I’m not receiving SMS messages!
If you are unable to receive SMS messages from Steam, check with your wireless provider that your wireless account is allowed to receive them. Steam will also stop sending SMS messages if too many have been sent to you, so waiting a few minutes to an hour may allow messages to come through again. You should also check to make sure that your phone’s inbox is not full.
My authenticator codes aren’t working!
If you are unable to log in using the authenticator codes:
Check the time on your phone and make sure it is accurate. The authenticator codes are generated using the phone’s time, and if the time is off, the codes will be incorrect.
If you have more than one account with an authenticator, make sure you are entering codes for the correct account.
You can remove the authenticator from the account; see the section below on authenticator recovery.

the giving one. dude were not that stupid. IM NOT GETTING THE CODE SEND TO MY 4G LTE UNLIMITED DATA IPHONE 6
The problem is not with the Steam Guard codes themselves, it is with the phone authentication step to set up the Steam Guard codes to begin with. As part of the process, you attach a phone number to the Steam account in question. Steam then immediately sends out an SMS code to confirm. These folks are getting an error message that Steam was unable to send that message, even if they did receive the SMS code. The error message screen does not allow them to enter the proper code, even if one has actually come from Steam, so they are stuck.
The time on the phone does not matter in this regard. Nor is it likely that their text message service was full at the time, as they tend to either have a ton of space or delete messages by first-in-first-out. Unlike voicemail there is generally no reason you can’t receive the latest message. My first guesses go like this. Either there is a Steam-side limit on the number of SMS that can be sent to one number in a particular period, or a limit on the number of accounts associated with a particular number. For some reason you have tripped one or the other. If you have already waited out any clock, best bet is to probably open a ticket and see if they can get you through the process, in case a flag is inappropriately stuck tripped.
if anyone has any logical ways to fix (i’ve done everything in this above guide), please help. all i want is to enable prime matchmaking and sell my hundreds of dollars of inventory to buy stuff.
ESP32 SIM800L: Send Text Messages (SMS Alert) with Sensor Readings
In this project we’re going to create an SMS notification system with the T-Call ESP32 SIM800L module that sends an SMS when sensor readings are above or below a certain threshold.
In this example, we’ll use a DS18B20 temperature sensor, and we’ll send a text message when the temperature is above 28ºC. Once the temperature has decreased below the threshold, we’ll send another SMS alert.
To send an SMS with the T-Call ESP32 SIM800L module, you just need to use modem.sendSMS(SMS_TARGET, smsMessage) after initializing a modem object for the SIM800L module (using the TinyGSM library).
Important: the SIM800L works on 2G networks, so it will only work in your country, if 2G networks are available. Check if you have 2G network in your country, otherwise it won’t work.
Watch the Video Tutorial
You can watch the video tutorial or continue reading for the complete project instructions.
Project Overview
This tutorial is divided into two sections:
You can modify this project for your specific case. For example, you may want to put the ESP32 in deep sleep mode and send an SMS every hour with the current temperature readings, etc.
TTGO T-Call ESP32 SIM800L
Besides Wi-Fi and Bluetooth, you can communicate with this ESP32 board using SMS, phone calls or you can connect it to the internet. In this tutorial, you’ll learn how to send an SMS notification.
Prerequisites
1. ESP32 add-on Arduino IDE
We’ll program the ESP32 using Arduino IDE. So, you need to have the ESP32 add-on installed in your Arduino IDE. Follow the next tutorial, if you haven’t already.
2. Prepaid SIM Card (SMS plan)
To use the TTGO T-Call ESP32 SIM800L board, you need a nano SIM card. We recommend using a SIM card with a prepaid or monthly plan, so that you know exactly how much you’ll spend.
3. Libraries
Installing the TinyGSM Library
Open your Arduino IDE and go to Sketch > Include Library > Manage Libraries. The Library Manager should open. Search for TinyGSM. Select the TinyGSM library by Volodymyr Shymanskyy.
Installing DS18B20 Libraries
In the Arduino IDE Library Manager, type “onewire” in the search box and install OneWire library by Paul Stoffregen.
Then, search for “Dallas” and install DallasTemperature library by Miles Burton.
After installing the libraries, restart your Arduino IDE.
Parts Required
To follow this tutorial you need the following parts:
You can use the preceding links or go directly to MakerAdvisor.com/tools to find all the parts for your projects at the best price!
Note: we had some signal strength issues with the antenna that came with the board package, so we’ve used another antenna (as shown below) and all those connection problems were solved.
Send SMS with T-Call ESP32 SIM800L
In this section, we’ll show you how to send an SMS with the T-Call ESP32 SIM800L board. Let’s build a simple example that sends an “Hello from ESP32!” message to your smartphone.
Copy the following code to your Arduino IDE. But don’t upload it yet, you need to insert the recipient’s phone number in the code.
How the Code Works
Insert you SIM card PIN in the following variable. If it’s not defined, you can leave this variable empty.
Then, add the phone number you want to send the SMS to. The number should be in international format, otherwise, it won’t work: (plus sign) and country code, for Portugal +351, followed by phone number.
Example for Portugal +351XXXXXXXXX
Configure the TinyGSM library to work with the SIM800L modem:
Include the following libraries:
The following lines define the pins used by the SIM800L module:
Initialize a serial communication to interact with the Serial Monitor and another to interact with the SIM800L module.
Setup the SIM800L pins in a proper state to operate:
Initialize a serial communication with the SIM800L module:
Initialize the SIM800L module and unlock the SIM card PIN if needed.
To send an SMS, you just need to use the sendSMS() method on the modem object and pass as arguments the recipient’s phone number and the message.
In this case, the message is “Hello from ESP32!“, but it can be replaced with other info like sensor data.
Demonstration
With the nano SIM card inserted in the module, upload the code to your T-Call ESP32 SIM800L board.
Go to Tools > Board and select ESP32 Dev Module. Go to Tools > Port and select the COM port your board is connected to. Finally, press the upload button to upload the code to your board.
Note: at the moment, there isn’t a board for the T-Call ESP32 SIM800L, but we’ve selected the ESP32 Dev Module and it’s been working fine.
After uploading the code, open the Serial Monitor at a baud rate of 115200 to see what’s going on.
After a few seconds, you should receive an SMS on the recipient’s phone number.
Troubleshooting
If at this point, you don’t receive an SMS, it can be caused by one of the following reasons:
ESP32 SMS Notification System
In this section, we’ll show you how to build an SMS notification system that sends a text message when the sensor readings cross a predetermined threshold temperature value.
Schematic Diagram
Copy the following code to your Arduino IDE. Insert the recipient’s phone number and set the threshold value. Then, you can upload the code to the T-Call ESP32 SIM800L board.
How the Code Works
In the previous example, we’ve already explained how to initialize the SIM800L and all the required configurations. So, let’s skip to the relevant parts for this project.
First, type your SIM card PIN. If it’s not defined, you can leave this variable empty.
Then, add the phone number you want to send the SMS to. The number should be in international format, otherwise it won’t work.
Define your temperature threshold. We’ve set it to 28 degrees Celsius.
Create a variable to keep track if an SMS was sent or not.
By default, the temperature is in Celsius degrees, but you can uncomment the following lines to use the temperature in Fahrenheit degrees. Then, you should also adjust the threshold value to match your temperature units.
After that, there’s a condition that checks if the current temperature value is above the defined threshold and if an alert SMS hasn’t been sent.
If that condition is true, send an SMS saying “Temperature above threshold: ” and the current temperature value.
As you can see, to send a text message, you use the sendSMS() method on the modem object. You just need to pass as arguments, the phone number you want to send the SMS to, and the message content.
After sending the message, set the smsSent variable to true to avoid multiple SMS alerts for the same threshold reached.
When the temperature goes below the threshold, we also receive an SMS.
These conditions are checked every 5 seconds, but you can change the delay time.
Upload the Code
After inserting the recipient’s phone number and SIM card pin code, upload the sketch to your ESP32.
After a few seconds, the code should be successfully uploaded.
You can also open the Serial Monitor at a baud rate of 115200 to see the current sensor readings.
If I put my finger on top of the sensor, the temperature will start increasing.When it goes above 28ºC, it sends an SMS.
When the temperature goes below the threshold, I’ll receive another SMS.
Wrapping Up
With this project you’ve learned how to send SMS with the T-Call ESP32 SIM800L module. Now, you can use this project in a real application and leave it sending SMS notifications when the threshold value is reached or send SMS with sensor readings every hour, for example.
To make this project battery powered, I recommend using deep sleep mode and wake up the ESP32 every hour to check the current temperature, because if you use the code in this project it will drain your battery quickly.

Sending Messages
Using Twilio’s REST API, you can send outgoing SMS messages from your Twilio phone number to mobile phones around the globe.
In this guide, we’ll explore how you can use Twilio’s Programmable Messaging API to:
Prefer a step-by-step guide to sending your first message? Check out our Programmable SMS quickstart in C#, Java, Node.js, PHP, Python, or Ruby.
If you’re looking to send and verify One-Time Passcodes (OTPs) via SMS, check out our Verify APIs for phone verification and 2FA.
Send an SMS with Twilio’s API
To send a new outgoing message from a Twilio phone number to an outside number, make an HTTP POST to your account’s Message resource:
You can post directly to the API with cURL or use one of our six supported helper libraries to send messages with C#, Java, Node.js, PHP, Python or Ruby.
This parameter determines the destination phone number for your SMS message. Format this number with a ‘+’ and a country code, e.g., +16175551212 (E.164 format).
If you send messages while in trial mode, you must first verify your ‘To’ phone number so Twilio knows you own it. If you attempt to send an SMS from your trial account to an unverified number, the API will return Error 21219.
You can verify your phone number by adding it to your Verified Caller IDs in the console.
From specifies the Twilio phone number, short code, or Messaging Service that sends this message. This must be a Twilio phone number that you own, formatted with a ‘+’ and country code, e.g. +16175551212 (E.164 format).
To get your first Twilio phone number, head on over to the console and find a number you like with SMS capabilities. If you’re interested in using a short code, you can apply for one via the console as well.
Note that you cannot spoof messages from your personal cell phone number without porting your number to Twilio first. Learn more here.
Tip: Send a Message from a Messaging Service
You can also enter a Messaging Service SID as the From parameter value when you send an SMS message. When you use a Messaging Service SID, Twilio will automatically send your message using one of the phone numbers in your service pool.
A messaging service is like a container for your phone numbers, bundled around common use cases, such as routing intelligence and content features. For more information, check out the guide on Sending SMS Messages from a Messaging Service.
The Body parameter includes the full text of the message you want to send, limited to 1600 characters.
If the body of your message is more than 160 GSM-7 characters (or 70 UCS-2 characters), Twilio will send the message as a segmented SMS.
Send an SMS message
Twilio will verify that you’ve included a valid Twilio phone number in the From parameter, and then either queue the call or return an error.
Check out the full API Reference for Messages for the full list of parameters you can include in your request. You can also find the parameters you can expect back from Twilio.
Monitor the status of your message
By including a StatusCallback URL in your API call, you can tell Twilio where to POST information about your message.
Please note that Twilio will make a POST request to your StatusCallback URL.
Send an SMS with a StatusCallback URL
Twilio will POST to this URL each time the status of your message changes to one of the following:
The parameters Twilio sends to your callback URL include a subset of the standard request parameters and some unique messaging parameters. You can see the full list in the API Reference for the Message resource.
Below is an example of the request parameters sent to the StatusCallback URL for a delivered message:
Include media in your messages
While you can send text-only messages almost anywhere on the planet, sending media is currently only available in the US and Canada.
Other MIME types are accepted by the API, but will not be modified for device capability.
Send an MMS message
The size limit for message media is 5MB.
To send more than one image in a message body, provide multiple MediaUrl values in your POST request (limited to 10 per message).
Use an Alphanumeric Sender ID
Alphanumeric sender IDs are used for branded one-way messaging. Instead of using an E.164 formatted Twilio phone number for the «From» value, you can use a custom string like your own business’ branding. Alphanumeric sender IDs may be used at no additional cost when sending an SMS to countries that support this feature.
Support for sending messages from an alphanumeric sender ID depends on your destination (‘To’) phone number and is not available everywhere. Please see this article for the full list of countries that support this feature.
A note on rate limiting
If you send multiple messages at once from a single Twilio sender (number or Alphanumeric Sender ID), Twilio will queue them up for delivery. Your messages may experience differing rate limits based on the sender you are using. For messages from a US or Canada long code number, the limit is one message segment per second (MPS). If you’re sending messages from a non-US or Canada long code number, or an Alphanumeric Sender ID, the upper limit is 10 MPS.
API requests for messages that exceed the specified rates will be queued and executed at the sending rate of your Twilio sender.
If your application tries to enqueue more than 4 hours’ worth of outbound traffic from a single sender (e.g., enqueuing more than 14,400 message segments to Canada over one long code phone number), the excess messages will fail with error 30001 (Queue Overflow).
If you need to increase your outbound SMS throughput, we recommend using a Messaging Service.
Are you planning to send out a large number of messages at a rate greater than one message per second? Consider applying for a short code.
Short codes are not subjected to the same rate limits as long-code numbers and may be a better option for you.

10 Reasons Why Some Messages Don’t Get Delivered
Share
Phoning a friend? If their phone is turned off, you’ll know it right away. But what about a text? You may never know if your message got delivered.
Global messaging using A2P (Application to Person) messaging (or SMS API) platforms is complicated, as most of the heavy lifting is done without you knowing it. Today, we’re going to show you the main reasons why SMS text messages go undelivered.
1) The recipient’s phone is switched off
If you get a busy signal while calling, you try again later. But when the SMS doesn’t get delivered on the first try, it is automatically re-sent in certain intervals. When the phone is available again, the message gets delivered.
If a certain amount of time passes without the SMS being successfully delivered, your mobile carrier might decide to stop trying. For example, Messente’s system is configured to try to deliver messages within 6 hours. If the message still won’t go through, it is eventually marked as ‘Failed.’
If you do get a ‘Failed’ warning on one of your messages, then you know that the delivery has definitely not been successful. At this point, you can try and resend the message, and the process will be repeated.
If this reoccurs, then it can be hard to know whether the recipient’s phone is switched off, or there is a more serious problem with either your phone or theirs. Most people will have their phones turned on at some point during the day, so if your message goes a whole 24 hours without being delivered, then it’s fair to assume that a switched-off phone is not the explanation.
2) False negative
Sending SMS text messages also requires receiving Delivery Reports (DLR) from carriers or operators. When the operator fails to respond with the correct receipt, the sender isn’t notified of the delivery and marks it as ‘Failed.’
Unfortunately, there are many cases where the operator has a problem on their end and the DLR is not sent through correctly. The most annoying thing is that the sender will have no idea that this is the issue and instead think that the problem lies elsewhere.
If you’re the person trying to send messages, then there’s really no way to know if you’ve run into a false negative. Ultimately, you only know if a message is delivered by receiving a reply.
USA, Canada, and most Latin-American countries are known not to provide delivery reports at all.
3) The number is roaming (abroad)
If you’re trying to send SMS messages to a number that is currently not in the home-country often causes problems, and frequently, delivery to numbers that are roaming is not guaranteed. It’s also worth noting that sending an SMS abroad can be very expensive, especially if you don’t have international messages included in your data plan.
If you’re a business sending messages to phone numbers all around the world, then you should check that you are collecting your clients’ country codes when they share their numbers with you.
4) The sender you are using is prohibited
Some countries or operators are blocking some types of senders or A2P messaging platforms. Japan, for example, doesn’t allow sending A2P SMS messages from regular phone numbers. Telia Sonera in Finland, on the other hand, blocks messages from alphanumeric senders like “CarService1″ or “BestHotel.»
These restrictions are put in place to prevent companies from engaging in high-volume messaging or spam. In these cases, it’s more difficult to run A2P marketing strategies, even if you’re not going to be spamming your clients.
Make sure to do your research around the rules and laws in your country. As long as you understand what is and isn’t allowed, you shouldn’t have any problems running a successful marketing campaign with an A2P strategy.
5) The carrier is blocking the SMS
Operators are also known to block some SMS routes from time to time. This also requires SMS services to re-route the message via another working route, which can cause temporary delivery issues. These problems are usually resolved quickly, but they can slow down your message delivery quite significantly.
Keep an eye out for any service updates from your provider since they will usually let you know when they’re experiencing problems. In the meantime, it might be worth holding back on sending too many messages that won’t be delivered right away.
6) Local regulations restrict SMS text messages
In some countries, local regulations restrict sending SMS messages to prevent spam. For example in some countries, messages notated as marketing can be sent only during workdays from 8 am to 8:30 pm. Although this can be annoying, it just takes a bit of planning to ensure you’re only sending marketing A2P messages in the allowed hours.
7) The number might be in the Do Not Disturb list
In some countries, the operators have a list, where handset owners can add their phone number by themselves so no messages from an A2P connection can be delivered. Ultimately, it’s problematic should one need to receive helpful information from a business, such as delivery information and order updates.
Some people might only have local numbers approved to avoid spam texts, so you’ll struggle to reach them if you’re not in the same country. There’s not really much you can do to solve this, aside from prompting your customers to add your A2P number to their «allowed» contacts.
8) The handset settings have «receive SMS messages» turned off
These days, SMS messaging isn’t the only way that people receive text messages. Many smartphones have internet-based messaging as their main person-to-person texting medium. Lots of people also use social network messaging apps to get in touch with each other.
As a result of this, it’s not uncommon for recipients to have their SMS messages deactivated, and some people might not even know that it’s turned off.
Often, there are conflicts between different applications that receive SMS texts, causing applications not to receive messages. If their SMS receiving capability turned off, SMS messages cannot be delivered properly to the phone number.
This issue can be further compounded by a user removing a conflicting app, but not changing SMS message settings to receive.
9) Conflicting SMS applications
Sometimes different applications on the handset can receive SMS messages. Due to their conflicts, the messages are not being delivered as the applications are conflicting and the message is not able to deliver to any of them, resulting in a failed message.
In simple terms, different applications are fighting to receive the same message, but in the end, it doesn’t get through to any of them. This is yet another problem that cannot be rectified from the sender’s side, and it’s down to the recipient to alter their receiving messages settings.
The only thing the sender can do is to make sure that they are sending messages to phone numbers designated to receiving SMS texts.
10) The carrier is experiencing technical difficulties
In some cases, the carrier or sometimes the hardware involved, is having some technical difficulties and messages are not able to be delivered.
We have seen in the course of years all manners of different occurrences, from the servers having a critical error to an accident in construction, resulting in a major data cable being cut.
If your carrier is having problems with their systems, then they should be letting you know what’s going on. Look out for updates online regarding outages or repairs from your carrier, and restrict your text messages when this is happening.
Conclusion
There can be quite a few reasons why your SMS message has gone undelivered. In many cases, there isn’t much you can do as a sender to help your text messages get through. There are a few things you can do to give your texts the best chance of reaching the recipient.
For example, you can make sure that you’re using the correct country codes at the start of your phone numbers. Additionally, ensure you’re only sending marketing text messages within the allocated time period of your country, so comply by local rules.
Hopefully, this list better explains delivery problems with SMS messages to help you better understand why your messages may not be delivered.
How to Send and Receive SMS Messages With Node.js and Express
This article originally appeared on the Nexmo blog, but I wanted to add some more content to it especially for the dev.to community. If you don’t want to follow along but you just want to try it out, I’ve put my code on Glitch and set up a Nexmo application with a few Nexmo phone numbers for different countries, you can send an SMS message to +442038973497 or +19373652539 and play with the autoresponder. If you want me to set up a number for your country, just tell me on Twitter, I’ll provision it and update the post here for others to use.
Nexmo has a couple of APIs that allow you to send and receive a high volume of SMS anywhere in the world. Once you get your virtual phone number, you can use the APIs to manage outbound messages (“sending”) and inbound messages (“receiving”). In this article, you will learn how to send and receive SMS messages with Node.js and Express.
We will first send an SMS with Node.js and the old SMS API (Nexmo’s first API) and then rewrite that code to use the new Messages API to send the same SMS. We’ll then build a Webhook that can receive SMS messages using express. We’ll focus in this article on sending and receiving SMS messages, but if you want to send and receive messages with Facebook Messenger, Viber or Whatsapp, you can do that as well with the Messages API.
You can extend the application we’re building here to reply to incoming SMS messages as well, or to include more complex, interactive elements and give you a head start building autoresponders for your SMS needs.
The code for this tutorial can be found on GitHub & Glitch.
Prerequisites
Before you begin, make sure you have:
Send an SMS Message With the SMS API
The SMS API is the first Nexmo API, and we’ll use it to send an SMS message to your phone number.
Install Node.js Dependencies
First off, initialize an NPM package, otherwise, older versions of NPM will complain about installing a package without having a package.json first. Just use the defaults for init, and then install the nexmo Node.js package.
Exit fullscreen mode
Initialize Dependencies
Exit fullscreen mode
We need to initialize the Nexmo node library we installed earlier, in the index.js file you created:
Exit fullscreen mode
Replace the values in there with your actual API key and secret. You can find those on the “Getting Started” page in the Nexmo Dashboard.
Send the SMS Message
The response data contains an array for all the messages that were sent, with information about their status. In most cases, it’s going to be 1 element in that array, but if the SMS was longer than 160 characters, it gets split into a multipart SMS, and then the array contains data about each part sent. If the status of the message is 0, the SMS was sent successfully, otherwise, the error data for the message is on the error-text property of the message.
Exit fullscreen mode
Depending on the country you’re trying to send the SMS to, there are regulations that require you to own the phone number you’re sending the SMS from, so you’ll have to buy a Nexmo phone number. You can do so in the Nexmo Dashboard or via the CLI:
Exit fullscreen mode
You can run the code and receive the SMS message with:
Exit fullscreen mode
Send an SMS Message With the New Messages API
There is a newer Nexmo API that deals with sending text messages called the Messages API. It is a multi-channel API, that can send a message via different channels, such as SMS, Facebook Messenger, Viber, and Whatsapp. The API is in Beta right now, so if we want to use it to send the same SMS message, we’ll need to install the beta version of the Nexmo node library.
Exit fullscreen mode
Run ngrok
If you haven’t used ngrok before, there is a blog post that explains how to use it. If you’re familiar with ngrok, run it with http on the 3000 port.
Exit fullscreen mode
Create a Messages Application
To interact with the Messages API, we’ll need to create a messages application on the Nexmo platform to authenticate our requests. Think of applications more like containers, metadata to group all your data on the Nexmo platform. We’ll create one using the Nexmo Dashboard, and that needs a name, and inbound URL and a status URL.
We’ll also save a keyfile on disk. Applications work on a public / private key system, so when you create an application, a public key is generated and kept with Nexmo, and a private key is generated, not kept with Nexmo, and returned to you via the creation of the application. We’ll use the private key to authenticate our library calls later on.
Initialize Dependencies
Let’s replace the contents of the file we created earlier. We need to initialize the Nexmo node library we installed earlier, in the index.js file you created:
Exit fullscreen mode
Replace the values in there with your actual API key and secret, the application id for the application you just created earlier, and the path to the private key you saved.
Send the Same SMS Message
In order to send an SMS message with the Messages API, we’ll use the nexmo.channel.send method from the beta version of the Nexmo node library. The method accepts objects as parameters, with information about the recipient, sender, and content. They vary for the different channels, you’ll need to check the API documentation for the other channels mentioned.
Exit fullscreen mode
You can run the code and receive the SMS message with:
Exit fullscreen mode
That’s it, you’ve sent the same SMS message using two different Nexmo APIs. You’ll notice the Messages API is a lot more verbose in usage, while both APIs need just one method to accomplish the same thing.
Receive SMS Messages
Create a Web Server
We’ll be creating our webserver using express because it’s one of the most popular and easy to use Node.js frameworks for this purpose. We’ll also be looking at the request bodies for the inbound URL, so we’ll need to install body-parser as well as express from npm.
Exit fullscreen mode
Let’s create a new file for this, call it server.js :
Exit fullscreen mode
Exit fullscreen mode
Create Webhook for the Inbound URL
Exit fullscreen mode
You can run the code with:
Exit fullscreen mode
Try It Out
Now send an SMS message from your phone to your Nexmo number. You should see the message being logged in the terminal window where you ran the code. It looks similar to this:
I hope it worked and you’ve just learned how to send and receive SMS messages with the Nexmo APIs and Node.js.
Autoresponder
One of the most common use cases for sending and receiving SMS messages is an autoresponder. I wanted to take this example a step further, so let’s build an SMS autoresponder with the things you just learned. If you combine the two things you’ve learned so far, together in the inbound Webhook, you have an SMS autoresponder, that replies with and SMS to all the incoming SMS messages.

Since I’m a fan of the NumbersAPI, I thought I’d use it for the autoresponder as well. I want to change the autoresponder to check if the text in the incoming SMS message is a number, and then use it to get a fact about that number from the Numbers API. Once I have a fact, I’ll send that back with the SMS message.

We’ll make a request to http://numbersapi.com/$
Let’s update the /webhooks/inbound route to make a request to the NumbersAPI before replying to the incoming SMS.

Try It Out
For reference, your final server.js file should look something like this one. If you’ve followed along this long, you’ll need to restart your server by running node server.js again in your terminal, and you’re good to go. Send an SMS message with a number to your Nexmo phone number and start interacting with your autoresponder.
Editor’s Note: Learn More About the Messages API
If you’re interested in knowing more about the Messages API, why not come along to our Vonage Campus event in San Francisco? Alex (the author of this post) is going to be there to give a workshop about builing talking websites – and he loves to chat about all things JavaScript in general so it’s a great opportunity to hang out with the Nexmo crowd and talk.
Read OTP from SMS flutter
I know about the package flutter_sms which is used for reading, writing and sending SMS.
But as I can see it will ask from user SEND_SMS permission also which is not needed and also google doesn’t allow asking for this permission if your app does not solely depend on this feature.
Can anyone help me with Reading OTP from SMS with flutter?
Or can help with writing the functionality natively for both IOS and Android and integrating it with flutter.

Trending sort
Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.
It falls back to sorting by highest score if no posts are trending.
Switch to Trending sort
For iOS, this package is not needed as the SMS autofill is provided by default, but not for Android, that’s where this package is useful.
No permission to read SMS messages is asked to the user as there no need thanks to SMSRetriever API.
You have two widgets at your disposable for autofill an SMS code, PinFieldAutoFill and TextFieldPinAutoFill.
Just before you sent your phone number to the backend, you need to let know the plugin that it need to listen for the SMS with the code.
To do that you need to do:
This will listen for the SMS with the code during 5 minutes and when received, autofill the following widget.
Sending an SMS with Phoenix
The Elixir programming language has been steadily gaining more adoption by developers, and for good reason. It is a functional language with an intuitive syntax and a supportive community around it. The most popular web framework in the Elixir ecosystem is Phoenix. It, like Elixir, is built to be intuitive and with a low barrier to entry.
As someone who does a lot of work in Ruby, and in Rails, I have been wanting to learn Elixir and Phoenix for a while. I took the dive and started working my way through the Elixir tutorials, and this past weekend created my first simple Phoenix app with the ability to interact with the Nexmo SMS API and send text messages.
Let’s walk through how I built it.
Starting Your Phoenix Server
The first thing that you need is to make sure that both Elixir and Phoenix are installed on your system. You can use their guides here and here to get up and running with the installation.
Once you have the language and the framework installed, you can create a new Phoenix app by running the following command from your console:
Exit fullscreen mode
This will create the basics of your new application inside a /sms_app directory. For simplicity sake, I would recommend answering in the affirmative to the setup prompts when it asks you if you want to install dependencies. Phoenix uses npm to fetch and install its Node dependencies.
Go ahead and cd into your new app directory. Once in there, we need to create the database for our application. By default, Phoenix uses PostgreSQL and assumes that there is a postgres/postgres PostgreSQL superuser. You can modify the Phoenix database settings in config/devs.exs first, and once you are ready, you run mix ecto.create from your console to set up the database for your application.
If you now run mix phx.server and navigate to https://localhost:4000 in your browser you will see a welcome page from Phoenix.
Your Phoenix server is up and running! Now let’s set up our application to interact with the Nexmo SMS API and start sending text messages. Before that, though, we need to create a Nexmo account and receive our API credentials.
Creating a Nexmo Account
Getting API Credentials
It is free to create a Nexmo account, and once you do, you are also given complimentary credit to begin playing with the Nexmo APIs immediately. Go ahead and navigate to the sign up page on the Nexmo dashboard and submit the sign-up form.
Once you finished signing up, navigate to the Settings page and fetch your API credentials.
Buying a Virtual Number
In many countries, you can send an SMS without a valid sender phone number, but if you plan to send your text messages in the US, for example, you need to provision a Nexmo virtual number and use it as your originating phone number.
There are two ways to acquire a virtual number with Nexmo. You can use the Nexmo CLI and execute the following commands from your console:
Exit fullscreen mode
The numbers shown in the above are just an example output. When you run the command you will see in real time numbers available for you to purchase. You can also specify a specific country, other than the US, by replacing the two letter US country code with another two-letter country code in the first command.
The other way to acquire a number is to navigate to the Numbers page in the Nexmo Dashboard and purchase a number using the web interface.
Configuring Your Phoenix App
Defining The Routes
Open up the router for your application in /lib/sms_app_web/router.ex and add the following inside the scope «/», SmsAppWeb do block:
Exit fullscreen mode
This tells our application where to direct two GET requests and one POST request. The GET /sms route is where the user will submit the SMS. The POST /send route is where the information will be submitted to. The GET /update route is where we will receive back information from the Nexmo API.
We now need to create those Controller methods.
Defining The Controller Methods
Let’s create a new Controller in /lib/sms_app_web/controllers called sms_controller.ex and add the following methods:
Exit fullscreen mode
As you can see we define a method for each one of the routes we created in the router:
Adding HTTPoison Dependency
Open up the mix.exs file in the root directory of your application, and within the defp deps do code block add the following on a new line:
Exit fullscreen mode
Then, from the command line, run the following to install the new dependency:
Exit fullscreen mode
Now we need to set up our views, so let’s go ahead and do that.
Setting Up The Views
Exit fullscreen mode
Now navigate to /lib/sms_app_web/templates and add an sms folder and inside of it we are going to create the index and the update templates.
Exit fullscreen mode
Exit fullscreen mode
The last step we need to do to make our app functional is configure our API credentials as environment variables.
Configuring Environment Variables
Exit fullscreen mode
Where there are blank quotation marks add the API credentials you received from the Nexmo dashboard, and the virtual phone number you purchased.
Once you are finished and the file is saved, run the following from the command line to incorporate your environment variables into your application:
Exit fullscreen mode
You now have a fully functioning Phoenix application that can send SMS messages with the Nexmo SMS API. You can navigate to https://localhost:4000/sms to begin sending messages.
If you are interested in seeing the full code for this walk-through, you can visit the repository.
Thanks for joining me on this journey beginning to learn Phoenix. There is a lot more to learn and I am excited to keep on going down this road!

Step 1: Are you in the right place?
Step 2: Describe your environment
Step 3: Describe the problem:
Steps to reproduce:
Observed Results:
The code executes with no error, but the sms is never sent to the device even though the codeSent callback gets fired. Nothing to show from the logcat
Expected Results:
I was expecting to receive and SMS with the verification code to complete the phone verification.
Relevant Code:
The text was updated successfully, but these errors were encountered:
samtstern commented Jun 13, 2017
@abba-maker thanks for the report! Do you have any access to a phone number not registered in Nigeria? Maybe a friend in another country? I want to see if this really is country-specific, as you suspect.
moderateepheezy commented Jun 14, 2017
@abba-maker I was having the same issue of not getting SMS, until I change from this
Changed to this
abba-maker commented Jun 14, 2017
@moderateepheezy I did that change but no luck. The SMS seem to be delivered to other carriers even without the change, but all MTN NG I’ve tried so far are not receiving the SMS. The problem seem to be specific to that carrier and unfortunately MTN NG are the largest carrier in my target location 🙁
Please #firebase help resolve the issue
moderateepheezy commented Jun 14, 2017
@abba-maker I just tried with MTN now and it worked, maybe you doing something wrong.
abba-maker commented Jun 14, 2017
@moderateepheezy that’s really weird, because all other carriers work just fine. Tried more than 4 different MTN NG numbers, non worked. But all other carriers works with same code
abba-maker commented Jun 14, 2017
I just tried verifying one of the numbers through firebase-ui auth demo but still did not receive any SMS. However, when I tried same number on the demo here on digits, I received an SMS with a code almost immediately.
inger commented Jun 27, 2017
samtstern commented Jun 28, 2017
Hey all. We’ve received a number of issues about people unable to get SMS sent to their device. These tend to be related to the device carrier and we’re working on fixing the issues. Instead of tracking them here (since I can’t really help) can you report such issues to Firebase support where they’ll get routed and tracked properly. Thank you!
jorgecasariego commented Sep 29, 2017
Hello everybody, in my case, I realised that this problem happens with all numbers that has ported from one provider to another. With phone numbers that has never ported Firebase Authentication works like a charm!
And also, the same happened with Digits. I had the same problem with ported numbers and my solution was give the user his verification code via a voice call but with unluckily Firebase it’s not possible to do this.
saryuvc commented Dec 7, 2017
first set the sha1 to firebase setting and generate google config.json then add to poject’s root directory and add to build.gradle dependency.
it’ll work properly
jermainec commented Jan 3, 2018
Hey guys, we are currently having what @jorgecasariego is facing too. Firebase Auth works well for numbers that haven’t been ported but the ones who ported are usually the ones who cannot receive the SMS despite numerous retries.
samtstern commented Jan 3, 2018
@jermainec if you’re having trouble with SMS delivery please reach out to Firebase support:

Debugging Common Issues with SMS
There are several common issues users run into when sending or receiving SMS messages. This guide outlines a few of the most common problems and provides troubleshooting tips:
My message wasn’t delivered
There are several ways to troubleshoot an undelivered SMS message.
I’m not receiving SMS messages on my Twilio phone number
There are several questions you should ask if messages are not reaching your Twilio number:
From/To pairs violating blocked sender rules
When a user opts out of receiving communications from a phone number that belongs to a Messaging Service, they are also opted out of all messages sent from that particular Messaging Service.
If you are to send messages to a recipient who has opted out this way, they must first text START or YES to your Twilio number to opt in again.
Why do I encounter duplicate messages?
The best way to begin debugging duplicate message issues is to review your message logs. You should look for a record of the message in question, as well as other messages that are duplicates that were sent within seconds of each other.
If you find duplicate messages sent within a few seconds of each other in your logs, it means that Twilio sent multiple messages to the carrier. This almost always means that Twilio received multiple POST requests from your application. Please check the HTTP request logs on your server to examine the requests you sent to Twilio.
It is extremely rare for Twilio’s system to create a duplicate message without receiving a POST from your application. If you’ve checked your server logs and only see one request to Twilio, please let us know by contacting support with the SIDs of the duplicated messages.
If you find only one message in your logs, it means that Twilio sent just one message to the carrier and the duplication happened within the carrier’s system. Users of all types of phones do occasionally receive duplicate messages, typically as the result of a safeguard that carriers implement when they suspect there may have been a service disruption. Duplicate messages may also occur when the recipient is roaming.
If duplicate messages occur for an extended time and with several different recipient carriers, please let us know by collecting the message records of the duplicated messages and contacting support.
My messages are delayed
When you send a message via the API Explorer, one of three things will happen:
For building messaging applications at scale, we have a document detailing best practices to get you started in a way that minimizes latency and shows you how to monitor your messages with Messaging Insights.
Need some help?
We all do sometimes; code is hard. Get help now from our support team, or lean on the wisdom of the crowd by visiting Twilio’s Stack Overflow Collective or browsing the Twilio tag on Stack Overflow.
Delivery receipts
Vonage’s adaptive routing then identifies the best carrier for your message. When the selected carrier has delivered the message, it returns a delivery receipt (DLR).
To receive DLRs in your application, you must provide a webhook for Vonage to send them to. Alternatively, you could use the Reports API to periodically download your records, including per-message delivery status.
Note: In most situations, a DLR is a reliable indicator that a message was delivered. However, it is not an absolute guarantee. See how delivery receipts work.
How delivery receipts work
Delivery receipts are either:
Not all DLRs guarantee that the target received your message. Some delivery receipts represent successful completion of only one stage in the delivery process, such as passing the message to another operator. Other delivery receipts are fakes. Because of this, Vonage cannot completely guarantee that a DLR is accurate. It depends on the countries you are sending messages to and the providers involved.
If your message is longer than can be sent in a single SMS, the messages are concatenated. You should receive a carrier DLR for each part of the concatenated SMS. Handset DLRs for a concatenated message are delayed. This is because the target handset has to process each part of the concatenated message before it can acknowledge receipt of the full message.
Understanding the delivery receipt
This is a typical DLR:
The most important fields are status and err-code as these tell you whether your message was delivered and, if not, what went wrong.
DLR status messages
The status field in the DLR tells you if your SMS was delivered successfully. Possible values are:
status | Description |
---|---|
accepted | Message has been accepted for delivery, but has not yet been delivered |
delivered | Message has been delivered |
buffered | Message has been buffered for later delivery |
expired | Message was held at downstream carrier’s retry scheme and could not be delivered within the expiry time |
failed | Message not delivered |
rejected | Downstream carrier refuses to deliver message |
unknown | No useful information available |
DLR error codes
The err-code field in the DLR provides more detailed information and can help troubleshoot a failed delivery. A non-zero code indicates that the message could not be delivered.
The other fields in the DLR are explained in the API Reference.
Using the SMS API in campaigns
Before you start your messaging campaign, check the country specific features guide for the countries you are sending to. If the country you are sending to does not supply reliable DLRs, use the Conversion API to provide Vonage with more data points and ensure the best routing.
Optionally, you can identify specific customers or campaigns by including a reference with each message you send. These are included in the delivery receipt. Pass your chosen reference into the request by specifying a client-ref parameter of up to 40 characters.
Authy One-Time Passwords (OTP)
For new development, we encourage you to use the Verify API instead of the Authy API. The Verify API is an evolution of the Authy API with continued support for SMS, voice, and email one-time passcodes, an improved developer experience, and new features including:
You are currently viewing the Authy API. New features and development will be added only to the Verify API. Check out the FAQ for more information and the migrating to Verify guide to get started.
Before sending a One-Time Password:
Once a user has been registered with your Twilio Authy application and receives an AuthyID, you can now implement 2FA, passwordless login or protect an in-application high-value transaction. Using the Authy API, you can send one-time passwords over voice or SMS channels.
Users can also install the free Authy app or use our SDK to generate offline TOTP codes ( soft tokens ). Soft tokens do not require wireless connectivity to issue and verify.
The Authy API is used to verify a user has access to the right phone number (for SMS and Voice channels) or has access to the right trusted device (for TOTP via the Authy App or use of the SDK).
Twilio’s Authy API follows the algorithms described in RFC 6238 and RFC 4226 to generate TOTP (Time-Based One-Time Passwords) passwords. It is also possible to use your own hardware tokens, please contact us for information on how to enable this type of 2FA.
Request a One-Time Password
When you call the API to start either an SMS or voice-based authentication, it automatically checks to see if that user has previously downloaded the Authy app or has an app installed that uses our SDK. If the user has the Authy App, by default, the API will not send the 2FA code via SMS or voice. Instead, a push notification will go to the device, prompting the user to start their app to get the code.
If a user has no record of installing a device, then the API will continue to send the code via SMS or voice. You can override the default behavior to force the sending of code via SMS or voice every time. This is a useful override if a user is specifically selecting «Send SMS» or «Get code via voice call» in your application UI.
For information on timing and other constraints like rate limiting, see our two-factor authentication best practices.
Parameters
Response
Name | Description |
---|---|
success Boolean | Returns true if the request was successful. (🏢 not PII ) |
message String | A message indicating what happened with the request. (🏢 not PII ) |
cellphone String | The country code and last two digits of phone number used to send the message with the rest obfuscated. (🏢 not PII ) |
ignored Boolean | True if we detected an Authy or SDK enabled app installed and we upgraded the OTP delivery channel from ‘SMS’ to Push Notification. Authy or SDK users are redirected directly to the requested token. (🏢 not PII ) |
device String | The type of the last device used by the user. This is only returned when we upgraded delivery from SMS. (🏢 not PII ) |
Supported Languages
I have a phone number problem
“Invalid number format”
The phone number must be entered in the following format ( +1 is the code for the USA ):
“Number blocked”
Phone numbers are temporarily blocked after sending the confirmation code. After adding a phone number, wait for the SMS with the code, or try requesting it again a few hours later.
Confirmation codes do not expire. No matter when you receive the code, you can always return to the Phone numbers page and enter it.
Why have I been asked to remove my number from other accounts?
One telephone number can be linked to no more than 10 accounts at the same time.
Confirmation code not delivered
The system has not yet processed the SMS (the maximum delivery time is 24 hours).
Your phone is turned off or does not have a signal.
You entered the wrong phone number. Make sure that you entered the country code correctly: +1 is the code for the USA.
You can find codes for other countries using a search engine.
Yandex cannot send SMS messages to your mobile operator.
If you don’t use a mobile phone or Yandex doesn’t send SMS messages to your service provider, you can change your password using an alternate email address or by answering the security question.
What should I do if I got a message about my phone number being added, changed, or deleted?
If you are trying to do something with your main phone number, just continue: Yandex sends email and SMS notifications about all operations for security reasons.
If you unexpectedly received a notification, it means that someone has access to your account. Don’t worry: you can easily restore access to your account using your main phone number. Without access to your phone, the hacker cannot delete or change the linked phone number for 14 days. During this time, you can:
Restore access and change your password.
Follow the Forgot your password? link and follow the instructions: get a recovery code and reset your password (when choosing a password, follow our recommendations).
Un-schedule the deletion or change of the main number on the Phone numbers page.
My confirmation code was sent to another person’s number
Your code may be sent to another person if you entered their number by mistake or are unlinking an old number that you no longer have access to (and could have passed to a new owner).
Your account is under no threat at all: a hacker cannot access your account if they only have your telephone number and confirmation code.

How to Send Text Messages Via Email for Free (SMS & MMS)
This may not be news for a lot of people, but you can send text messages via email, for free, to most major cellular providers. This tip is stellar in that it is part stupid frugal trick (save money on texting from your cell phone by emailing for free), part productivity (you can probably type faster from a normal QWERTY keyboard than a phone), and part tech geek. This article includes step-by-step instructions on how to text via email.
SMS Vs. MMS
First a primer on SMS versus MMS. SMS, or Short Message Service is also commonly referred to as a “text message”. With a SMS, you can send a message of up to 160 characters to another device. Longer messages will automatically be split up into multiple texts. Most mobile phones support this type of text messaging. Using an SMS gateway is great if you only want to send strictly text messages to someone with a basic text plan.
MMS, or Multimedia Messaging Service can be used to send longer messages and/or pictures, video, or audio content. It is most commonly used to send a photo taken with a camera phone to another phone. Most new mobile phones with multimedia capabilities support MMS. Due to the added capabilities, it often makes sense to send message via an MMS gateway if both are available. If the recipient has a more basic plan and cannot receive the message (e.g. image or video), then you can revert to an SMS gateway (and opt to send the media in an email instead).
How to Send a Text Message Via Email (List of SMS & MMS Gateways):
To send a text message via email, you must use a SMS or MMS to email gateway (email address). Just substitute a 10-digit cell phone number for ‘number’ for each carrier below:
If your provider does not have a gateway address listed here, most providers use one or multiple of the 5 largest networks in the US: AT&T, Sprint, T-Mobile, U.S. Cellular, and Verizon. T-Mobile recently purchased Sprint, but Sprint’s network is still active. If a provider isn’t listed here, you could find out which network is being used by that provider (usually listed under cellular network settings on the phone) and test the gateways above for those networks. AT&T and T-Mobile are used for GSM phones and Sprint, U.S. Cellular, and Verizon are used for CDMA phones.
Making the Most of Texting from Email
To take this to the next level from a productivity standpoint, I’d recommend creating ‘contacts’ within your email account so that you aren’t constantly looking up all of those cell numbers that you don’t have memorized each time you send an email.
How to Add Cell Numbers for Text Messaging in Gmail Contacts:
In the following example, I’m going to add my mother’s cell to my Gmail contacts. Let’s say that her phone provider is Verizon and her number is (555)123-4567. You should be able to set up contacts through most email programs (if you can’t, switch to Gmail).
1. Go to contacts.google.com:
2. Click the “Create contact” button (upper left corner):
3. Put in contact’s ‘name’ and the word ‘cell’ to clarify between email and cell contacts in both the “First Name” and “Nickname” (under “Show More”) fields:
4. When composing a new text message in Gmail, simply type in the new contact, enter your text, and send!
What About Texting To Email (Instead of Texting from Email?
Texting to email instructions are much easier than texting from email, and there are plenty of uses for it.

Hi,
My friend has SK telecom how can she send email texts?
Have your friend send text to your email. Then keep the reply path. Duh buddy
Just answer the question and help someone out, no need to be rude.
I just tried to text message from my “gmail” via @sms.mycricket.com and it wouldn’t work … I am REAL sure that I did exactly as “G.E. Miller” said … but the “text message” did not arrive at me phone.
Any help would be appreciated.
Keep your ignorance to yourself Ala frigging Ba Ba.In this country we try to be civil otherwise head to the nearest airport and do us all a big favor…..get out.
He did say “buddy” so that makes it okayer.
But apparently, in this country we’re still racist af! Did it occur to you, 1. You have no idea where he was born based on 3 little letters, and 2. People are ruDE because they are rude, even, (GASP!) right here in good old’ America. Sometimes I wonder who people like you would have to hate if the continents never drifted apart…. simplton. Smh.
Can you reply to an SMS received from email?
You can use this trick for sending voice mail converted to text from your landline to a text instead of email. I personally do not check new emails to my personal email accounts as I get them but I do check my texts real time.
wait so can u send attachments like uhm. songs and stuff to people. lets say i want to send a song to my phone. but i dont have internet browser. i have unlimited text,pic and email. but im not sure if email texts bill as internet use. if it doesnt can i send stuff from my email to my phone?
Nope, attachments seam to be removed (at least with verizon), though I expect you could text say an image back to the email and access it on the computer, so it’s somewhat of a one-way gate for attachments.
This is not true. You can send attachments. The extension is different thought. As for verizon it is [email protected]
I tried sending someone a text message to boost moblie but it seems it didn work and I can’t tell them to send a message to my email. Any ideas? Anybody??
@Nathan – Haven’t tried attachments out yet. If it works and your provider doesn’t charge you, check back and let us know.
waht about for criket?
What about Boost mobile and other non contract phones?
All non-contract phone carriers (also known as MVNOs) in the US use one of the four major networks to carry their calls, AT&T, Verizon, T-Mobile or Sprint.
I use H2O Wireless which is an AT&T MVNO. So the [email protected] works for me. I have a friend who uses Black Wireless, another ATT MVNO and it works for him too. These are the only two I have tested, so I don’t know it it will work for others, but it’s worth a try.
To find out which network your MVNO uses go here
http://www.prepaid-wireless-guide.com/compare-payg.html
and scroll down the column to where it says Network.
You can also get an idea by comparing the coverage maps. If it is orange, it’s probably AT&T. If it’s pink it’s T-Mobile. Also, sometimes there is a Wikipedia article on the MVNO, which will tell you which network it uses.
Just want to understand.if I’m on Verizon do I create [email protected] for all my contacts or do I use there provider after there number for txt messages
In my Gmail contacts, I just added another custom field under phone numbers and called email text” and entered the contacts mobile number plus the extension there.
Straight talk non contract phones This will work for pics
Hi! We are going to try to use this texting through email at my facility. It works, but there is a HUGE paragraph that automatically comes along with the message about confidentiality, etc. How can I get rid of this?
@Mary – That block of disclaimer text at the bottom of your emails is being automatically attached from some sort of email gateway service that IT has setup for your company. Other than sending the message from another external address, I doubt you’ll be able to get rid of it. You could ask them to exclude an address. Maybe request a shared mailbox that you could use for sending from? Just a thought…
Mr. Miller: Can I convert incoming text messages to my email, or resend them myself from my Tracfone to my email?
How does the message show up on your cell bill? Or the receivers?
Is there anyway it can be sent anonymously…..I don’t want my name or number to show up to the receiver. Thanks, Chris
i dont think so but it seems like you are hiding something
This is an anonymous sign up, we all are. And so what? People should be allowed some privacy.
we did this for our church, had to create a separate email acct., The email acct name shows up. when we first tested it, we used my email, my name was listed. so I don’t think you can do it anonymously.
I can’t get the ATT text messages to work at the above address. Do I have to send out one message at a time?
here’s one to add to the list, was hard to get too.
boost mobile [email protected]
Content of message would not go through for us at first.
[email protected]
this did work.
Hi! I know this has been here a while but I’m hoping someone is still around to help me! I’ve been trying to forward an email from my gmail account to my husband’s boost mobile. I’ve tried it with @myboostmobile.com, @sms.Myboostmobile.com,
@mms.myboostmobile.com. I even tried it without using the word my. Oh and I’ve put his 10 digits before all of them, of course. None of them have worked.I got mail delivery notices on the one without “my” and the one with “mms” stating they had permanently failed because there was no such domain. I didn’t receive one on the first two I listed here but they still didn’t go thru. Since Sprint has bought out Boost but didn’t change the name is it possible that I might should be using the one for Sprint. Also, I’ve already tried sending myself a text to my email because mine is boost as well, before anyone wants to be rude. Anyway, it didn’t work,something’s on my galaxy s3 are synced automatically so all it showed was my email stress. It looked like I emailed my own email account! Lol I really need too get him this email but I’m at a loss. As anybody out there? Can anyone help me please?! Even if you can’t have a blessed day and thanks for starting this in the first place, I’ve read thru the posts and learned several things I didn’t know, so I really appreciate you helping others! You must have some really great karma by now! Lol. I gotta laugh out I may just start screaming and break my phone!
Chris, when you send text messages from email, the text message will have your email address but it won’t have your phone number..is that what you’re asking? So the receiver will have whatever name your email is set up for but no number will be displayed. BTW, sending anonymous = fishy.
Yes Matt – you should always disclose all your information when txting or emailing people. Name, address and phone number are very important that everyone knows whom they are talking with. To help people be more comfortable with you, also send you birth date, SSN, mothers maiden name, all credit card and bank account numbers and all pins. ( I really enjoy talking with stupid people.)
Hey Matt – I’m commenting so much lately than this post (5 years) that everyone may have gone by now, but, thanks to this page, I tried it for the first time last night and it actually did show my e-mail address to the recipient. See my individual posting for more really interesting information about what I’ve learned and the 4-digit codes (someone has probably already mentioned this – lol).
And, Matt, some people are just jerks. You try to help and there’s always at least one person that has to say something nasty and can’t just be grateful for the info. Well, I am! All this information has been super helpful and opened a whole new world for my friends, because I refuse to pay for texting on my phone (have a great OLD plan-includes rollover mins.-lol) when I pay enough already for home computer internet service (no internet on my phone either)! This makes us both happy. I’m also not a person attached to my phone, so they can text to my e-mail, but know they aren’t necessarily going to get an immediate response if I’m away from my computer. LOVE IT. Thanks everyone!
THANKS Matt! for taking the time to post the info. I’ve done this b4 but it’s so few and far between (like leaving my cell phone at home) that I forget how to do it, so your post was great help AND your productivity idea was a great idea as well. Quote: “To take this to the next level from a productivity standpoint, I’d recommend creating ‘contacts’ within your email account so that you aren’t constantly looking up all of those cell numbers that you don’t have memorized each time you send an email.”
This tip has been very useful and my friends receive my text I send from my e-mail, however, I am not receiving their text messages back to my e-mail I only receive this. “This mobile text message is brought to you by AT&T” but no message from my friends. What am I doing wrong?
I am having the same problem.
MOST of the time the emails to text work outgoing and incoming. But several times I’ve gotten the same message as AISL.
Has anyone been able to correct this?
Try having your husband text to your email and see if the reply address shows.
This is great to use, especially when you don’t have a phone. I do this all the time with my friends.

Programmable SMS Python Quickstart
Ahoy there! All messaging transmitted using Twilio’s messaging channels is treated as Application-to-Person (A2P) messaging and subject to Twilio’s Messaging Policy. For detailed information on policy rules to ensure you remain compliant while using Twilio’s services, please see our Acceptable Use Policy.
With just a few lines of code, your Python application can send SMS messages with Twilio Programmable Messaging.
This Programmable Messaging Quickstart will walk you through the entire process step-by-step, starting with setting up your Twilio account all the way through sending an SMS using a Messaging Service.
In this Quickstart, you will learn how to:
By the end of this Quickstart, you’ll have a solid foundation for building and scaling with Twilio’s Programmable Messaging for your specific use cases.
Already have a Twilio account? Go ahead and skip this section.
You can sign up for a free Twilio trial account here.
Install the Twilio CLI
We’ll use the Twilio CLI (command line interface) for a few tasks, so let’s install that next.
The suggested way to install twilio-cli on macOS is to use Homebrew. If you don’t already have it installed, visit the Homebrew site for installation instructions and then return here.
Once you have installed Homebrew, run the following command to install twilio-cli :
The suggested way to install twilio-cli is by using Scoop, a command-line installer for Windows. If you don’t already have it installed, visit the Scoop site for installation instructions and then return here.
Note PowerShell will need to be run as an administrator to avoid common permission issues when installing via Scoop.
twilio-cli can be installed using the Advanced Package Tool ( apt ) on most distributions such as Debian, Ubuntu, and Mint.
To do so, run the following commands in your terminal:
For other installation methods, see the Twilio CLI Quickstart.
Run twilio login to get the Twilio CLI connected to your account. Visit https://www.twilio.com/console, and you’ll find your unique Account SID and Auth Token to provide to the CLI.
You can reveal your auth token by clicking on the eyeball icon:
Get a phone number
If you don’t currently own a Twilio phone number with SMS functionality, you’ll need to purchase one. With the CLI, run:
Select a phone number to add it to your account.
Next, we need to install Python and the Twilio Python Helper Library.
Install Python and the Twilio Helper Library
If you’ve gone through one of our other Python Quickstarts already and have Python and the Twilio Python helper library installed, you can skip this step and get straight to sending your first text message.
To send your first SMS, you’ll need to have Python and the Twilio Python helper library installed.
Install Python
If you’re using a Mac or Linux machine, you probably already have Python installed. You can check this by opening up a terminal and running the following command:
You should see something like:
Twilio’s Python server-side SDK supports both Python 2 and Python 3. You can use either version for this quickstart, but we recommend using Python 3 for future projects with Twilio unless there are specific libraries your project needs which are only compatible with Python 2.
Please note: Twilio’s Python 7.x library only supports Python 3.6+.
Install the Twilio Python Server-side SDK
The easiest way to install the library is using pip, a package manager for Python that makes it easier to install the libraries you need. Simply run this in the terminal:
If you get a pip: command not found error, you can also use easy_install by running this in your terminal:
If you’d prefer a manual installation, you can download the source code (ZIP) for twilio-python and then install the library by running:
in the folder containing the twilio-python server-side SDK library code.
Send an outbound SMS with Python
Now that we have Python and twilio-python installed, we can send an outbound text message from the Twilio phone number we just purchased with a single API request. Create and open a new file called send_sms.py and type or paste in this code sample.
Send an SMS Using Twilio
You’ll need to edit your send_sms.py file a little more before your message will send:
Replace the placeholder credential values
Swap the placeholder values for account_sid and auth_token with your personal Twilio credentials. Go to https://www.twilio.com/console and log in. On this page, you’ll find your unique Account SID and Auth Token, which you’ll need any time you send messages through the Twilio Client like this. You can reveal your auth token by clicking on the ‘view’ link:
Open send_sms.py and replace the values for account_sid and auth_token with your unique values.
Please note: it’s okay to hardcode your credentials when getting started, but you should use environment variables to keep them secret before deploying to production. Check out how to set environment variables for more information.
Replace the from_ phone number
Remember that SMS-enabled phone number you bought just a few minutes ago? Go ahead and replace the existing from_ number with that one, making sure to use E.164 formatting:
[+][country code][phone number including area code]
Replace the to phone number
Replace the to phone number with your mobile phone number. This can be any phone number that can receive text messages, but it’s a good idea to test with your own phone so you can see the magic happen! As above, you should use E.164 formatting for this value.
If you are on a Twilio Trial account, your outgoing SMS messages are limited to phone numbers that you have verified with Twilio. Phone numbers can be verified via your Twilio Console’s Verified Caller IDs.
When you send an SMS from your free trial phone number, it will always begin with «Sent from a Twilio trial account.» We remove this message after you upgrade.
Save your changes and run this script from your terminal:
That’s it! In a few moments, you should receive an SMS from your Twilio number on your phone.
Are your customers in the U.S. or Canada? You can also send them MMS messages by adding just one line of code. Check out this guide to sending MMS to see how it’s done.
In this code sample, we are making a POST request to the Programmable Messaging API’s Message endpoint in order to create a new outbound message. We are using the twilio-python library’s built-in create method, but you could make this request using the Twilio CLI (that you already installed), curl, or a request module of your choosing.
Use the Twilio CLI to send an SMS
Use curl to send an SMS
Set up a Twilio Messaging Service
Congratulations, you’ve sent your first SMS with Twilio Programmable Messaging and received it on your personal device.
At this point, we have acquired one Twilio phone number and used it to send one outbound SMS. You can imagine a time in the not-so-distant future where you’ll need a more robust, feature-rich way to send messages, such as:
In the next part of the Quickstart, we’ll walk through setting up your first Messaging Service. You can think of a Messaging Service as a container to hold all of your available phone numbers (and other senders) and comes with features that you may need along your messaging journey.
Create a Messaging Service with your phone number
Run the following Twilio CLI command to create a Messaging Service that we will use to send our first programmable SMS.
Take note of the Messaging Service SID (It starts with “MGXXX. ”). We’ll need it to send our next message.
Next, add the phone number you just purchased. Forgot the number already? No worries, you can list it with the Twilio CLI:
Add your phone number to your newly created Messaging Service with the following command:
Send an SMS from your Messaging Service
Sending an outbound SMS from a Messaging Service is similar to sending from an individual Twilio phone number. The primary difference is replacing the from_ parameter with the messaging_service_sid to indicate that you are sending from a phone number within your Messaging Service’s sender pool. (Currently, there is only one phone number in your sender pool, so we’ll be sending from that one.)

Describe the bug
Upon signing up with a phone number, the Verification SMS with the 6 digit code is never sent to the phone number. After trying to resend the code multiple times, the message is never received.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
A SMS Verification code is sent to the phone number used during SignUp.
Additional context
I have already raised a Service Quota Increase ticket and have that increased. I have also explicitly set the spending limit on the SNS (Text Messaging) Console.
I have tried using the Cognito Hosted UI to Sign Up and am facing the exact same issue with that. The verification SMS is never received.
My SNS service is working as expected as I can send out other SMS communication to our users using the aws-sdk.
Also, if the user registers using the email address, an email is promtly sent to the user with the verification code. Only SMS are not delivered.
The text was updated successfully, but these errors were encountered:
shreyansjain commented Jul 20, 2020
+1 to this issue.
We have recently started experiencing the same issue (Spending Limit/Service Quota issues have already been resolved).
Wanted to highlight few observations:
I have asked AWS team to confirm if it was related to recent changes due to ILDO
AakashPat commented Jul 20, 2020 •
@shreyansjain
Similar situation at my end.
In order to get a faster resolution to avoid impact on business, I am seeking approval for getting a Support Plan from AWS. It will cost us 29$/month. All this for something that should be very straight forward in the first place.
shreyansjain commented Jul 20, 2020
That’s strange, UserPool in ap-south-1 is the failing for me to send to IN numbers (CA/US numbers are getting delivered).
The worst case is, this the first point of entry to our platform and if users are not able to receive verification codes, they won’t be able to use the platform.
I’ll update once I hear back from them and/or please do the same.
AakashPat commented Jul 20, 2020
shreyansjain commented Jul 21, 2020
Heard back from AWS PM:
I will initiate the Premium Support team once I hear an update from you.
AakashPat commented Jul 21, 2020
It has been 15 hours since the ticket and I haven’t heard back from them. It is a System Impaired issue which had a 12 hour SLA. Certainly leaves a bad taste in my mouth about AWS Support.
Once I have a response, I will let you know.
AakashPat commented Jul 22, 2020 •
@shreyansjain, Finally heard back from AWS Support after 36 hours.
I understand that you are facing issues while using Cognito MFA as messages are not getting delivered to your users when using Frankfurth region.
As you are already aware, Cognito MFA messages are sent using SNS in the closest region[1], hence in order to investigate the issue we will need to troubleshoot from the SNS side in eu-west-1 (Cognito Userpools in eu-central-1 is currently using SNS SMS in eu-west-1 as SNS SMS was only recently released in eu-central-1).
Unfortuantely, there is no public documentation about which regions rely on which other regions for such situations. Also, there is no way for the users to know which is the closest region to the one they have selected. Upon pointing this out, I got another reply from the AWS Support team.
Yes, Cognito User Pools in eu-central-1 currently uses SNS SMS in eu-west-1 region.
Unfortunately, there is no public documentation that lists the mapping, but it mentions the following[1]:
«SMS messages from Amazon Cognito user pools are routed through the closest AWS Region that’s supported by Amazon SNS worldwide SMS delivery.»
However as SNS SMS started supporting eu-central-1 region only recently in March 2020[2], Cognito service is yet to update this change for Cognito Userpools in eu-central-1 to use SNS SMS in eu-central-1 region.
I can confirm that there exists a feature request with the Cognito team to update the documentation with this SNS SMS mapping, I have also added the details of this case and how it impacted your business to the feature requests so that the team can understand the issue and prioritize it. Rest assured that your feedback has been conveyed to the team.
Send an SMS message during a phone call with Node.js and Express
In this tutorial, we’ll show you how to use Twilio’s Programmable Voice and SMS to send a text message during a phone call.
We’ll write a small Node.js web application that:
Ready? Let’s get started!
Sign up for a Twilio account and get a phone number
If you have a Twilio account and Twilio phone number with SMS and Voice capabilities, you’re all set here! Feel free to jump to the next step.
Before you can receive phone calls and send messages, you’ll need to sign up for a Twilio account and buy a Twilio phone number.
If you don’t currently own a Twilio phone number with both SMS and Voice capabilities, you’ll need to buy one. After navigating to the Buy a Number page, check the «SMS» and «Voice» boxes and click «Search»:
You’ll then see a list of available phone numbers that meet your criteria. Find a number that suits you and click «Buy» to add it to your account.
Create an Express app that accepts incoming calls
We’ll be building a small Express web application that accepts incoming calls and sends the caller an SMS. Let’s start by building out the code that receives the call and says something to the caller.
Set up your development environment
To download the code used in this tutorial and run it, you can clone this GitHub repository and follow the setup instructions in the README.
If you don’t already have the Twilio Node.js helper library installed, you can do so with the following command:
You will also need to install Express and body-parser. If using npm, this looks like:
Handle incoming calls
Handle the inbound call
In this code sample, we leveraged Twilio’s Node.js library to create a voiceResponse that says some text to a caller. We can ignore the blurred lines for now: those will come into play later when we’re ready to create an SMS from this call.
Make sure to include this line at the end of your file:
You can now run this Express application:
You can check that your app is running by going to http://127.0.0.1:8000/answer in your browser. You should see some text that says «Thanks for calling! We just sent you a text with a clue.»
But how do we tell Twilio to use this response when someone calls our Twilio phone number?
Allow Twilio to talk to your Express application
For Twilio to know how to handle incoming calls to your phone number, you’ll need to give this local application a publicly accessible URL. We recommend using ngrok.
If you’re new to ngrok, you can find more information here about how it works and why we recommend using it when developing locally.
Once you’ve downloaded ngrok, make sure your Express application is running. Then, open a new terminal window and start ngrok:
If your local server is running on a port other than 8000, replace ‘8000’ in the command above with the correct port number.
You should see some output that tells you your public ngrok URL.
Now you can configure your Twilio phone number to use this app when someone calls you:
Save your changes. Now you’re ready to test it out!
Call the Twilio phone number that you just configured. You should hear your message and the call will end.
Great! Next, we’ll get some information about the caller so we can send them a follow-up SMS.
Get your caller’s phone number from Twilio’s request
When someone dials your Twilio phone number, Twilio sends some extra data in its request to your application.
While Twilio sends a lot of data with each inbound call, the two pieces of information we need are:
While we won’t be using them in this app, many values are included in Twilio’s request to our application. Check out the full list of parameters Twilio sends with every request.
To send our caller an SMS, we’ll need to access that To and From information. Update your /answer route to include the following:

SMS Service Providers
SMS technology has risen to become one of the most critical communication channels for most individuals and organizations. Whether you’re running a survey, making a booking, or advertising special offers to your customers, there are no better means than the use bulk SMS services. Emails can go unread, calls can be unanswered, leaflets can be thrown into the trash, but when you send a text message, it will be read in the first moment it pops up in the phone’s notification bar. It’s like a norm for human beings to want to read a text message once received on their mobile phone.
And given how affordable they can be, businesses can get higher ROI when using SMS than any other communication channel. However, depending on your business’s unique needs, you ought to select a provider that offers several pricing tiers, have an option for bulk SMS, is reliable, and boast other functions such as an API. Before we progress further, let’s try and understand what SMS Service providers are all about.
What is an SMS Service Provider?
An SMS service provider can be defined as a business entity that specializes in the provision of SMS text messages, even though it is not a mobile network operator itself. It acts as the intermediary between customers and mobile network providers. SMS service providers enter into agreements with vast network providers, and they are be authorized to utilize these networks to facilitate the exchange of SMS messages. They offer customers an interface that they can use to send and receive SMS messages. Sometimes, these service providers may utilize SMS gateways to provide more sophisticated services.
What is an SMS Gateway?
An SMS Gateway is a protocol that enables a computer to send and receive SMS messages through mobile network SMPP protocol. The SMS gateway converts the message being sent into a language that can be easily understood by the network receiving it. This ensures that the text message reaches the intended target without any delays. An SMS gateway permits companies to utilize their email, CRM software, or computer to deliver SMS text messages to customers. It then returns a delivery report detailing the delivery time and status.
Years ago, SMS gateways were real pieces of hardware with sim cards and radios. Each was connected to a mobile network to send messages in a similar way to a typical cellular phone. However, today’s SMS gateways route SMS messages to the mobile networks through an SMPP interface that is exposed by the systems via APIs. SMS service providers that leverage SMS gateways are preferred since they deliver loads of features that benefit any enterprise, whether in education, healthcare, retail, or entertainment industries.
Which is the best bulk SMS service provider?
While several companies offer bulk SMS services, only a few of them are top-notch. In this piece, we take a sneak peek of this world-class bulk service provider.
Twilio
When it comes to bulk SMS services, no company comes close to Twilio. Boasting a programmable SMS platform that runs on a professionally balanced software platform, this provider can offer bulk SMS and guarantee prompt and safe delivery. Some of the unique features that make it one of the most respected SMS service providers include multi-tenancy, scaler, geo match, scaler, and queueing.
Since most organizations in the modern market use APIs, you’ll also be glad to know that Twilio integrates cutting-edge APIs that allow you to program SMS messaging. Twilio not only adds robust messaging capabilities to your enterprise, but also helps you to add phone verification, and get deliveries whenever you send a message to a customer or prospect. When it comes to selecting the most accomplished SMS service provider, you can trust that Twilio is a fantastic choice.
SMS technology has risen to become one of the most critical communication channels for most individuals and organizations. Whether you’re running a survey, making a booking, or advertising special offers to your customers, there are no better means than the use of bulk SMS services. Emails can go unread, calls can be unanswered, leaflets can be thrown into the trash, but when you send a text message, it will be read in the first moment it pops up in the phone’s notification bar. It’s like a norm for human beings to want to read a text message once received on their mobile phone.
And given how affordable they can be, businesses can get higher ROI when using SMS than any other communication channel. However, depending on your business’s unique needs, you ought to select a provider that offers several pricing tiers, have an option for bulk SMS, is reliable, and boast other functions such as an API. Before we progress further, let’s try and understand what SMS Service providers are all about.
Tinder SMS Verification 2022: The 8 Most Important Things to Know About Tinder SMS Verification
The Tinder SMS Verification is meant to confirm that you are the owner of your Tinder account.
Other than verifying that you are the owner of your account, it is a way to know that you can receive texts.
These texts are important in that, they help inform you of log-ins to your account.
They also help send you codes whenever you are logging in to Tinder.
This is especially the case if you are using a different device to log in to your account.
In short, the Tinder SMS verification code is meant to send you codes and keep your account private.
Check Benefits and reasons for using a private number for SMS verification versus Google Voice, burner numbers, and public phone numbers.
It means that another person using the same number cannot access your account.
They will have to prove ownership by first of all getting the code sent to their phone.
It is not that likely that someone will have a similar number to yours.
The other alternative would have been using an email account.
The major idea behind the Tinder SMS is to verify your identity.
This is very important today in this world of hackers and Fake Tinder Profiles.
Online dating just is not as safe as it used to be.
There are so many Tinder Catfish accounts out there looking to harm you.
This will be a straightforward analysis of the Tinder SMS error from these:
As a bonus you will get:
There is no room to waste your time but just to help you understand this phenomenon better.
A time of 7 minutes is enough to skim through this topic. Shall we begin?
1. The Tinder SMS Verification, What it is?
The Tinder verification code is a code used to establish a Tinder user’s identity.
The Tinder SMS verification is used to make sure that you are the owner of the account.
It also is a way to ensure that other users do not create double accounts with similar details.
This code is important to inform you that someone is logging in to your account.
That is why whenever you log in, you are asked to verify your account.
This is a security feature by Tinder to keep your account safe.
Choosing to log in with your phone number will prompt Tinder to send you a verification SMS.
This is a security feature to prevent Tinder users with ill motives from using your account.
We however know that you can Browse Tinder Anonymously.
2. Why You Are Not Getting an SMS From Tinder
The most obvious explanation is the Tinder Error 5 000.
The server error may prevent you from getting a Tinder SMS.
This is caused by a failure in connection to the Tinder servers.
This failure is from both the Tinder Company and the user.
The Tinder servers may be down at some time or under maintenance.
The user may also have a slow internet connection.
It may be that your phone has a full inbox and needs you to delete some messages.
There will be other reasons that we will discuss later on in this analysis.
3. How To Bypass Tinder SMS Verification
The most direct way is to use a virtual number.
We suggest avoiding these public phone services, google voice, and burner numbers as they are being used many times for verification which can get you shadowbanned again. I highly suggest using a private number for Tinder SMS verification.
You could always log in with your Facebook account.
However, here I will suppose that you already had chosen the phone number as the method.
A virtual phone number will do.
Remember, if you do this many times, Tinder will ban you from the online dating app.
It is only consequential if you overdo it.
There is another way to bypass it.
I think we mentioned it briefly. That is, use Facebook login.
All Tinder does is connect to your Facebook and log you in.
Remember that this only works if you were not banned previously.
Another way is to get a new SIM card if at you were previously banned from Tinder.
The last way is to use your friend’s phone number, get the code and continue with Tinder on your device.
Those are your best options.
4. How To Get a Verification Code for Tinder
Well, it is not hard really.
Remember to keep your device online so that Tinder is still live.
Once that is done, enter the code on Tinder.
These are the steps in getting a Tinder verification code. An Example of an SMS code is: your tinder code 63473 is don’t share.
That means you have to keep the code safe, by not sharing it with nobody. The Tinder verification code is not permanent.
It keeps on changing every time you log in, especially from a different device.
If you were to delete your cache files from the browser, you will have to sign in afresh.
Sometimes that is the way to fix Tinder SMS error.
5. How You Are Causing the Tinder SMS Error
There are some things that you are doing wrong as regards the Tinder SMS error.
These are the reasons from your end that prevent you from getting the text from Tinder.
The knowledge of these issues will also help you to fix the errors.
They include among these:
Tinder not only reads your number but also your device.
If you keep on using different devices, you make Tinder think that you are not legitimate.
Are you guilty of any of these reasons?
Online dating is easier if you also do your part.
Tinder is meant to be enjoyed not to make your life harder.
You may not always have the knowledge to fix these issues but at least, you can avoid them.
6. Tinder Error 5 000
Apart from you being to blame for not receiving Tinder code SMS texts, Tinder also is to blame.
The online dating app operates in many countries and may experience server challenges.
Their servers may be highly busy in the many countries that they operate in making you inconvenienced.
The server error 5 000 is an obstacle to using Tinder completely.
Hopefully, for you, this is not the main reason that you cannot receive texts nor enter the code received.
7. Tinder Not Sending SMS code – Causes of SMS Error
The ‘Tinder Help’ site helps shed light on the causes of the SMS error. But is not enough details on why we are not receiving the Tinder code.
These help us at least understand better why they happen:
Some of the Reasons why Tinder won’t send code verification, and what you can do to fix it:
1. Your Phone Carrier is not supported on Tinder
What if Tinder says that my phone carrier is not supported?
Your phone carrier is your mobile service provider (it’s where you get your SIM card from); And if Tinder says that your phone carrier is not supported, what they mean is that your mobile service provider isn’t supported.
This could be because Tinder policy doesn’t support all carriers registering. The best thing you can do is get an online disposable number that has carriers supported by Tinder.
We’ll update you once we find another way to do this without breaking any rules.
2. There could be a delay by Tinder while trying to reach your phone.
It may also be that the Tinder servers are down.
Tinder advises that you wait for a few minutes before giving up. Or before trying again numerous times.
3. Your mobile/internet network could be slow.
This is also one of the reasons you might see the Tinder Error 5 000.
What you can do in this case is upgrade your internet or restart your WIFI device or move to a different room in your house to get a stronger mobile network.
4. It may be caused by your mobile service carrier.
Maybe the carrier (a.k.a mobile service provider) company has blacklisted your phone. Find out.
5. Your apps may be causing it to have a glitch.
Several apps replace the original phone SMS app such as Truecaller or QuickText and others.
Try disabling these or uninstalling them and see whether there will be a change.
6. Your message inbox (storage) is full.
Delete some old messages that you are no longer using. Yes, that could be an issue that Tinder can’t send you the code.
7. You have tried to submit your number many times.
Forcing Tinder to send you an SMS code by submitting your phone number many times only will make it worse. If this is you, then calm down and wait for a day or so to try again.
These are seven of the major issues that plague why tinder won’t send verification code.
Why isn’t Tinder fixing it?
Well, because most of the problems listed are not coming from Tinder but the mobile carrier.
They are also coming from the users themselves.
A good example of a user being ‘guilty’ is not deleting past messages thereby having a full inbox.
8. Texting Apps that work with Tinder – How To Get a Tinder SMS Online
Several texting apps give you random virtual phone numbers to receive SMS and calls.
Texting apps are providers of phone numbers that can be used temporarily – We’re not addressing apps like Whatsapp, Viber, or Telegram!
The Texting Apps provide you with a virtual phone number that most probably was being used before by someone else. These texting apps require Credit Cards and other details about you while creating an account.
Tinder is very aware of these providers and strict about them. We do not recommend using these public numbers because you will not have a good experience with Tinder at all.
Here is the list of texting apps that works with Tinder and receives SMS verification codes:
If you do take Tinder a little bit seriously, we prefer to avoid using texting apps, because most likely you will get a number that was used before by someone else. God knows what the previous user did.
This is negative because other previous users could also have access to your current Tinder account.
Here’s what a previous user says about one of these texting apps:
I installed the app they gave me a number and within 30 min. I was getting random sales calls and group texts. I had to turn my phone on silence. I’ve used this app for years during the school year then the summer uninstall it. I’ve never experienced this. Quality has really gone down. I would have given it a one star if I had paid for it.
Some argue that a fake number will get you banned from Tinder. Well, that depends on how many times they have attempted to bypass Tinder. If you try way too many times, you will eventually be banned.
Just once is harmless. You may just get a warning and that is if you get caught.
You can get a Tinder SMS online through various legitimate services.
If you follow and receive SMS online, you will be able to get a virtual phone number.
From here, you will be able to receive your SMS online. It’s easy.
Remember to use this service carefully and in moderate ways, otherwise, you raise your chances of being banned on Tinder.
Using it once is okay but not too many times.
A Quick Bonus
Tinder can not only ban you but also blacklist your device.
This means that if you were trying to create a new account, you will not get an SMS.
So what should you do?
You can use a trick to defeat the blacklisted status of your device.
Use another phone or computer and a different phone number.
Create an account and select log in using your phone number.
You will be able to get your verification SMS.
If you were to delete all your browsing history, you can use your new account on your device.
It will work just fine.
So, could it be that your SIM card is blacklisted by Tinder?
9. Recap
The Tinder SMS error is a pretty straightforward concept.
It is either you get the SMS or you don’t.
Here is your quick recap:
Those are the most important things to remember.
Conclusion
There will always be a glitch on any online dating app.
This is why you should not be too hard on Tinder.
The SMS error on Tinder can happen on any other online dating site.
Tinder is just more famous than others, hence the issues that are tied to it.
Remember, it is used in many countries worldwide.
There will be errors expected.
Your part is just to ensure that you follow the steps we have mentioned above.
These are on how you cause the SMS error. Try to avoid those mistakes. Tinder is worth it.
That is why you must continue enjoying the app. Do not let one error get you down.

How to Send an SMS With TypeScript Using Twilio
Writing Node.js applications with TypeScript means you can take advantage of the TypeScript type system and tooling. We’ve seen on this blog how to send an SMS message with Node.js, but let’s have a look at how to do this with TypeScript.
What you need
To follow this tutorial you will need:
Once you’ve got all that, let’s dive into the code.
Getting started with TypeScript
Let’s start a new TypeScript project for this example. In a terminal, run the following commands to create a new project directory and create a package.json file.
Now we need to install some dependencies. We’ll need TypeScript in our development dependencies so we can compile our code to JavaScript before we run it and we’ll need the Twilio Node module which makes it easy to use the API to send SMS messages.
Initialise the project with a tsconfig.json file by running:
We’ll leave the tsconfig.json with the default settings. If you are interested in changing them the settings are well commented. You can also read more about the different options in the TSConfig Reference.
We need a file into which we will write our program. Create a file called index.ts :
Next we’ll set up a script to compile our TypeScript to JavaScript and a script to run the JavaScript. Open package.json and to the «scripts» property add the following:
Let’s write some TypeScript
Open index.ts and start by importing the Twilio library:
For this script we will send the parameters in via environment variables. Environment variables are a great place to store information that you need in an app but shouldn’t check in to source control. You can read more about setting environment variables in this post.
We will need our Account SID and Auth Token, available in your Twilio console, a Twilio phone number that can send SMS messages and a phone number to send the message to. We’ll get those variables out of the environment like so:
Using the accountSid and authToken initialise a Twilio API client:
Using the client, we can make an API request to create a message. To the create method we need to pass:
The create method returns a Promise when the request is successful and we’ll log the SID of the message resource we created to show it worked.
Squiggly red underlines mean we have failed to satisfy TypeScript with this code. In this case, TypeScript is not sure what the process object is. We may know that it is a Node.js global that provides information about and control over the running Node.js process, but TypeScript does not. To tell TypeScript about process we need to install the types for Node.js. We can do that with:
With that complete, the errors move further down the script.
For this example let’s wrap the client initialization and message creation in a conditional based on the presence of the required variables. We can then show an error message if one is missing.
You should find that there are no more red underlines, which means we can compile the TypeScript into JavaScript. In the project directory, run the script we defined earlier:
When the script completes, you will find an index.js file in your project. You can now run the other script we defined earlier to send an SMS message.
Of course, you should set all the relevant environment variables. When running a single script like this, we can do it all on one line:
That’s it, you’ve sent an SMS message using TypeScript and Twilio.
What is Error 38 when sending SMS? How do you resolve it?
Yoodley is reader-supported. When you buy through links on our site, we may earn an affiliate commission.
Error 38 is an error that occurs exclusively on Vodafone network carriers when your network operator is unable to send SMS. The error code goes as “Error 38: Unable to send SMS”.
According to the information we’ve gathered from public forums, Error 38 can occur for a variety of reasons, including:
How to resolve Error 38 when sending an SMS?
Below we have enlisted four ways you can solve Error 38 on a Vodafone sim when sending an SMS:
Solution #1 – Restart your device
The act of turning away from your computer and onto your phone may appear to be a simple tech support repair; however, it will work more often than not in most cases. It’s possible that simply restarting the phone will be sufficient to resolve the problem permanently.
Solution #2 – Manually select Vodafone network
The Preferences menu provides you with a number of options for dealing with the issue of low connectivity, and it may be able to resolve the Vodafone error 38 for you. The ability to select the system operator manually may resolve the issue almost immediately.
Solution #3 – Set the SMSC manually
Despite the fact that this procedure is usually handled at the conclusion of the network provider, you may be required to manually enter the SMSC (SMS service centre number). You’ll need to get in touch with the network operator in order to have the correct SMSC number delivered to your location.
Solution #4 – Reset Network Settings
If you have tried every possible repair option and none of them have worked, the only thing left to do is to reset the system settings to their default values. This option allows you to delete all of the Wi-Fi, Bluetooth, and mobile network configurations that have been previously saved. In the event that nothing else could be done to resolve the Vodafone error 38, perform a community reset on the phone.
How to fix error code 17?
The Error Code 17 may also appear when you try to send a text message on your phone. When a user is sending a message, the issue is said to appear a few minutes after the message is shown as ‘Sending’. Users are met with an error message that reads “Can’t send. Please try again. (Error code 17)”.
When you’re disconnected from a WiFi network, the intended message appears to be sent, with the mileage varying from network to network. This however seems to be only a temporary workaround.
To fix the error code 17, you must unlock your phone and turn off your phone’s WiFi connection. By disabling the WiFi toggle in Quick Settings, you can accomplish this.
It’s also possible to go into the Settings app and disable ‘Wi-Fi’ by swiping the toggle next to it.
An update from your device manufacturer should include a permanent fix for the problem if it has been reported widely. As soon as a fix is released, you can simply update your device to the latest software version to fix the problem.
Other Ways To Fix “SMS Not Sending” Error Code 17 On Android
How to Fix SMS Fails to Send in Android?
There are a number of reasons why Android’s SMS messages may not be delivered (or be received, but this article will focus on the failure to send). Please visit Phone Not Receiving Texts for more information.
It’s possible that your SMSC number is to blame if you’re unable to send or receive texts despite being able to receive them fine.
Solution 1: Setting SMSC Through Secret Phone Menu
Many users recommend converting the SMSC number to PDU format if you receive an ‘Update error’ when manually adding the SMSC. Below we have described how you can convert the SMSC number to PDU format:
Solution 2: Setting SMSC in Default Messaging App
It’s not uncommon for people to prefer a different texting app to the one that comes pre-installed on their devices. Apps like Textra, Chomp, EvolveSMS, and even the SMS feature in Facebook Messenger appear to be fancier than the stock app.
In order to keep your phone from becoming bloated, root users often disable the default SMS app. For some reason, most third-party SMS apps don’t have a way to set the SMSC number, whereas the default app usually does.
Due to the fact that the default SMS app has access to the SMSC, while third-party apps aren’t, this is typical.
If any of this describes your situation, try the steps below:
Solution 3: Resetting the SMSC in Another Phone
If nothing else has worked, some people report that they were able to fix the problem by setting the SMSC in a different phone, then putting the SIM card back in the one that was having problems.
How to Fix ‘Error 98 SMS Termination Denied’ Error on Android?
One billion people use Android, making it one of the most popular mobile operating systems. Customizability options and fast speeds make it a popular choice. Almost everyone has a mobile phone with SMS capabilities, which lets them communicate with friends and family via text message. “Error 97:SMS Origination Denied” Error has been plaguing Android users recently.
Below are a few reasons that could trigger Error 97:SMS Origination Denied when sending an SMS:
Corrupt Data: In some cases, the problem may have been caused by corrupt data in the messages app. Sending and receiving messages may be hindered due to corrupt data.
Corrupt Cache: For faster loading and a better user experience, the messages application stores certain launch configurations and other data in a cache. However, this cached data may become corrupted over time, causing the error.
Once you have a basic understanding of the problem, we can now move on to the solutions. Make sure to follow the order in which they are presented in order to avoid a misunderstanding.
Solution 1: Clearing Cache
If the messages application’s cached data is corrupted, the messages may not be delivered. As a result, in this step, we will only clear the cache, which will not delete any of the messages. Follow the steps below:
Solution 2: Clearing Data
If clearing the cache does not resolve the problem, we will clear the data for the Messages app in this step. Ensure that important messages are backed up in case they are accidentally deleted. Clearing the data for the Messages app does not delete messages on some phones, but it does on others. To do so, follow the same steps as in the previous method, but this time select the “Clear Data” option rather than the “Clear Cache” option.
Top 10 Sites to Receive SMS Online without a Phone
Many websites these days ask you to provide some form of verification when you want to sign up to a service. This includes most things like shopping sites, email accounts, discussion forums, gaming services, blogs, social media and etc. Basic forms of verification are just supplying an email address or perhaps solving a captcha to confirm you are a real person and not a spam bot.
Other forms of verification can try to be a bit more secure by requiring you to enter more personal information like a name, address or zip code. Another method to try and identify you are a legitimate user is phone verification which usually comes in the form of an SMS message with a code sent to your mobile phone. The problem with that is not everyone can or wants to hand over their own phone number.
Some important services might use more secure two factor authentication where it would make more sense to use your real phone number. But for other things that are not so important or just require a one time verification, using a number that is not tied to your own phone might be preferable. Thankfully, there are websites that offer services where you can get a text message sent to another phone number.
Using an online SMS receive service is easy, simply note down the number provided and give it to the service or individual that requires a number to send the message. After a short period of time, the message you are waiting for should appear. Do note that these messages are not private or secure and can be seen by anyone, so make sure no personal information is going to be received.
Here we list 10 websites that offer a free SMS message receiving service which allows you to get text messages sent to you without using a real phone.
To verify if these services worked, we simply sent a message to the listed number via Skype SMS, World Text SMS or the aFreeSms Text Messaging Service. Usually one worked if another didn’t. If the service had no more than eight or maybe ten numbers, we tried to test them all. If there were more numbers than that we tried a random selection of six or seven, usually from different countries where possible.
1. Sellaite SMS RECEIVER
Sellaite SMS RECEIVER has been around for several years and is different from most of the other services here because it uses three phone numbers from Estonia (country code +372). They seem to be quite fast at taking down offline numbers and replacing them with working numbers, which should help with reliability.
All three numbers worked fine and received messages within ten or so seconds. A great feature here is the voice messaging option where you can receive and play messages from voice based phone verification. Play and Stop buttons will be visible on the title bar of messages with voice playback. Note the Send SMS button on the main page points to a paid service.
2. FreePhoneNum
FreePhoneNum has a sizeable selection of twenty seven numbers available although they are all from two countries. The United States has twenty one numbers and Canada has six. We tested five US and three Canadian numbers at random and all were received within a few seconds.
A text sending service is available where you can send up to 5 messages to US/Canada numbers per day. There is also a free voice call service on the website where you can use your speakers/microphone for a two way phone call. Again, this is only to North American +1 international code numbers.
3. FreeTempSMS
FreeTempSMS appears to be from India and has a total of eight numbers. Six are for the United States and two are for Canada.
At the time of writing, all eight numbers worked fine and all SMS messages were received within a few seconds. There is a registration option but we couldn’t work out what it’s for because it doesn’t seem to do anything and there is no information.
4. SMS-Online
There are eight phone numbers available with SMS-Online, one each from the United States, Puerto Rico, France, Malaysia, Indonesia and Sweden. The United Kingdom has two numbers. Just click the Open button for any country to see the messages list. Do note there is usually a VPN ad at the top of the messages list so you might have to look below that to see your SMS message.
The only number we had trouble with was one of the two from the UK. The rest seemed to work OK so in effect we had seven working countries with one number each. You can subscribe with an email to be notified when new numbers are added. The service is multi language and supports special character like Chinese or Cyrillic. Emojis are also supported
5. Twilio
Twilio is not going to be for everyone and you really don’t need it for just a few SMS messages. It requires registering for a trial account but ironically you have to supply a phone number for verification. One of the other services here might receive the SMS but most numbers will already have been used. Otherwise, you will have to decide if giving your real phone number to Twilio is worth it.
The big advantage of Twilio over the other services here is all received messages are only viewable by anyone that knows the login credentials. Therefore, it is much safer if you want to receive personal or private messages.
6. Fakenum
Fakenum has five numbers listed which are all in the United States. Simply click the “Receive Free SMS” button and then on one of the numbers you want to use. Press the “Show my SMS Message” button or refresh the page to view new incoming messages.
When we tested, four of the five numbers worked. Messages didn’t take long to arrive and were displayed within a few seconds. It’s unlikely to work for you but this was the only free SMS service we found that was accepted by Twilio for phone verification. Could be worth keeping an eye on these numbers if you are trying to get a Twilio trial account.
7. Online-sms
Online-SMS boasts around seventy numbers coming from fourteen countries. These include the United States, Canada, the United Kingdom, Belgium, France, Poland, Sweden, Portugal, Italy, Austria, Switzerland, Spain, Denmark and Latvia. We tested a random selection of seven working numbers from the US, France, Belgium, UK and Poland.
With this many numbers available there’s a very good chance some or even many will not be working at any one time. Check the last message received time to get an idea of what is currently active (don’t trust the on page “online” status). Do be aware that during testing some messages were taking 30 minutes or more to arrive. A few numbers were receiving within a couple of minutes but most did take some time.
Another service that uses the same API or was developed by the same company is 7Sim.net. It looks very much the same as Online-sms but has far fewer working numbers.
8. Receive-SMS
Receive-SMS has been around for several years and is, in fact, one of a couple of sites that still works from our original article in 2013 (the other was Sellaite). It used to have six European based numbers but now there are four from the United States. The latest messages from all numbers are merged into the bottom of the main window.
We found that three of the four numbers worked fine but the fourth hadn’t been active for a few months or more. There is an option to get notified by email when new numbers are added although they might not change that often because the inactive number has been offline for quite a while. Paid private numbers are available if you need more from your SMS receiving service.
9. Sms-verification
This service has three numbers which are all from the United States. When messages are received from any of those numbers they appear in a merged list in the lower part of the main window.
During testing, all three numbers worked fine and each received an SMS message within a few seconds. Receive-SMS.com links directly to this service on some of its pages so they both appear to be run by the same company or are at least using the same API.
10. Mytrashmobile
While we have received messages from all three numbers, they weren’t all working at the same time during any one session. The USA number, however, did seem to work consistently. There are Android and iOS apps available and links to other related sites for spoofing texts, emails, WhatsApp and phone calls.
Another useful resource to check is called The SMS Bay. This website doesn’t have its own numbers but lists several SMS receiving services and their active numbers in a table that is supposedly updated every five minutes. Some are already listed here but quite a few are not. The Texts and Age columns don’t appear very accurate so it’s best just to go to the linked website and check for activity yourself.
Final Note: Even if some of them appear to be working, the phone numbers that are used to receive SMS messages online can still be easily blocked using TeleSign’s PhoneID that can identify the type of the provided telephone number such as VoIP, fixed landline, mobile and etc.
You can also be prevented from using one of these numbers for phone verification because someone else has already used it and a unique or lesser used number might be needed. If that is the case there is little option but to keep trying different numbers until you find one that works.
I can’t receive the verification code sent to my phone number/email address linked with my account
I can’t receive the verification code sent to my phone number/email address linked with my account |
1. The phone number or email address may be incorrect.
Verify that you have entered the correct phone number or email address.
2. The message may have been blocked by the carrier or email service provider.
You may have reported this type of notification messages or emails as junk information.
3. The verification message may have been blocked by your phone.
4. You may have a poor network connection.
The verification message sent by the server may be delayed due to factors such as poor network signal reception or unavailability of the carrier’s network. Please wait for a while, or obtain the verification code again after the penalty time elapses.
Tips: If you have reached the maximum number of verification code requests, try again 24 hours later.
How to Send and Receive SMS Messages With Node.js and Express
Vonage has a couple of APIs that allow you to send and receive a high volume of SMS anywhere in the world. Once you get your virtual phone number, you can use the APIs to manage outbound messages (“sending”) and inbound messages (“receiving”). In this article, you will learn how to send and receive SMS messages with Node.js and Express.
We will first send an SMS with Node.js and the old SMS API and then rewrite that code to use the new Vonage Messages API to send the same SMS.
We’ll then build a Webhook that can receive SMS messages using Express. We’ll focus in this article on sending and receiving SMS messages, but if you want to send and receive messages with Facebook Messenger, Viber or Whatsapp, you can do that as well with the Messages API.
You can extend the application we’re building here to reply to incoming SMS messages as well, or to include more complex, interactive elements and give you a head start building autoresponders for your SMS needs.
The code for this tutorial can be found on GitHub & Glitch.
Prerequisites
Before you begin, make sure you have:
Vonage API Account
To complete this tutorial, you will need a Vonage API account. If you don’t have one already, you can sign up today and start building with free credit. Once you have an account, you can find your API Key and API Secret at the top of the Vonage API Dashboard.
This tutorial also uses a virtual phone number. To purchase one, go to Numbers > Buy Numbers and search for one that meets your needs.
Send an SMS Message With the SMS API
The SMS API is the first Vonage API, and we’ll use it to send an SMS message to your phone number.
Install Node.js Dependencies
First off, initialize an NPM package, otherwise, older versions of NPM will complain about installing a package without having a package.json first. Just use the defaults for init, and then install the @vonage/server-sdk Node.js package.
Initialize Dependencies
We need to initialize the Nexmo node library we installed earlier, in the index.js file you created:
Replace the values in there with your actual API key and secret.
Send the SMS Message
The response data contains an array for all the messages that were sent, with information about their status. In most cases, it’s going to be 1 element in that array, but if the SMS was longer than 160 characters, it gets split into a multipart SMS, and then the array contains data about each part sent. If the status of the message is 0, the SMS was sent successfully, otherwise, the error data for the message is on the error-text property of the message.
Depending on the country you’re trying to send the SMS to, there are regulations that require you to own the phone number you’re sending the SMS from, so you’ll have to buy a phone number. You can do so in the Vonage API Dashboard or via the CLI:
You can run the code and receive the SMS message with:
Send an SMS Message With the Messages API
There is a newer API that deals with sending text messages called the Vonage Messages API. It is a multi-channel API, that can send a message via different channels, such as SMS, Facebook Messenger, Viber, and Whatsapp. The API is in Beta right now, so if we want to use it to send the same SMS message, we’ll need to install the beta version of the Nexmo Node.js SDK.
Run ngrok
If you haven’t used ngrok before, there is a blog post that explains how to use it. If you’re familiar with ngrok, run it with http on the 3000 port.
Create a Messages Application
To interact with the Messages API, we’ll need to create a messages application on the Vonage API platform to authenticate our requests. Think of applications more like containers, metadata to group all your data on the Nexmo platform. We’ll create one using the Vonage API Dashboard, and that needs a name, and inbound URL and a status URL.
We’ll also save a keyfile on disk. Applications work on a public / private key system, so when you create an application, a public key is generated and kept with Vonage, and a private key is generated, not kept with Vonage, and returned to you via the creation of the application. We’ll use the private key to authenticate our library calls later on.
Initialize Dependencies
Let’s replace the contents of the file we created earlier. We need to initialize the Nexmo node library we installed earlier, in the index.js file you created:
Replace the values in there with your actual API key and secret, the application id for the application you just created earlier, and the path to the private key you saved.
Send the Same SMS Message
In order to send an SMS message with the Messages API, we’ll use the nexmo.channel.send method from the beta version of the Nexmo node library. The method accepts objects as parameters, with information about the recipient, sender, and content. They vary for the different channels, you’ll need to check the API documentation for the other channels mentioned.
You can run the code and receive the SMS message with:
That’s it, you’ve sent the same SMS message using two different Vonage APIs. You’ll notice the Messages API is a lot more verbose in usage, while both APIs need just one method to accomplish the same thing.
Receive SMS Messages
Create a Web Server
We’ll be creating our webserver using express because it’s one of the most popular and easy to use Node.js frameworks for this purpose. We’ll also be looking at the request bodies for the inbound URL, so we’ll need to install body-parser as well as express from npm.
Let’s create a new file for this, call it server.js :
Create Webhook for the Inbound URL
You can run the code with:
Try It Out
Now send an SMS message from your phone to your Vonage number. You should see the message being logged in the terminal window where you ran the code. It looks similar to this:
Sending SMS with Twilio in a Node.js Application
With the increase in the number of mobile devices around the globe today, and numerous mobile applications available to us, SMS is becoming the de facto standard for verification.
SMS comes in handy for verification purposes at various stages in our applications, this is especially a great option on mobile applications.
It should be noted that SMS is not only useful for verification purposes but can be essential across various business use cases such as operational/transactional alerts, order placements, etc. TextMagic has a comprehensive article on a number of SMS use cases for businesses here
Today, we are going to explore how to use Twilio for sending SMS in a Node.js application.
Prerequisites
To follow through this tutorial you must have the following:
If you don’t have Node.js installed just head on to the official Node.js website to get a copy of Node.js for your platform. Once you install node.js you will automatically have npm installed.
Head over to Twilio now to get an account set up in less than 2 mins free of charge.
Getting started
To get started, create a new directory for the application by running the following command on the terminal:
Initialize the directory to create a package.json file by running:
Open the newly created folder in your editor of choice.
Your folder structure should now look like the one below:
Create a simple Express server as shown below in an index.js file:
To demonstrate a simple use case of SMS in our application, we are going to create a simple user registration system and use Twilio to send an activation code to the user’s phone number.
The purpose of this tutorial is to show how to send SMS using Twilio in our Node.js application hence all the best practices of user registration are not considered.
In the index.js file, paste the following code:
Now that we can create a user successfully, let’s now integrate Twilio to help us send verification SMS to new users as soon as their account is created. Head on to Twilio site and create your account. After you successfully created an account your dashboard should look similar to the one below:
Get a Free Twilio trial number
From your Twilio dashboard, click Get a Trial Number to get a free number which we’ll use as the sender when sending out the SMS to users. You will be able to customize your SENDER ID once you upgrade your account by subscribing to the Twilio platform but our trial number will suffice for the purpose of this tutorial.
Integrating Twilio in our App
Create a new file in the project directory and name it twilio.js. In the new file copy and paste the following code:
NOTE:
Depending on the format you’re getting the phone number from your user, you may need to format it to meet the international format for sending and receiving SMS. Read more on that topic here
Now, in the index.js file, add the following code:
Now we are ready to send SMS in our node.js application so let us test our work
Testing our application
Just before we send our first SMS, we need to add a verified phone number to our Twilio account. This is so because we are on the trial version. So, from your Twilio dashboard, click on verify phone number and verify a phone.
You should have at least one verified phone number already if you set up your account properly.
Save your work and start the server by running node index.js on the terminal
Open up Postman and send a POST request to the /users endpoint with the right parameters
Congratulations! You’ve just successfully sent an SMS from a Node.js application.
