Asp net send sms to mobile

ASP.NET is a powerful programming that allows developers to web applications. One common requirement in web development is the to send SMS messages to mobile devices. In this article, we will explore how to achieve this using ASP.NET.

To send SMS messages in ASP.NET, we need to use a third-party SMS gateway . There are several SMS gateway providers available, such as Twilio, Nexmo, and Plivo. These services provide APIs that allow developers to send SMS messages programmatically.

Setting up the SMS Gateway

Before we can start SMS messages, we need to sign up for an account with an SMS gateway provider and obtain the necessary credentials. Once we have the credentials, we can proceed with integrating the SMS gateway into our ASP.NET application.

Installing the SMS Gateway SDK

To interact with the SMS gateway API, we need to install the SDK provided by the SMS gateway provider. Most SMS gateway providers offer SDKs for various programming languages, including ASP.NET. These SDKs provide a set of classes and methods that simplify the of sending SMS messages.

Sending SMS Messages

Once we have installed the SDK, we can start sending SMS messages. Let's take a look at an example using the Twilio SMS gateway.

using Twilio;
using Twilio.Rest.Api.V2010.Account;

class Program
    static void Main(string[] args)
        const string accountSid = "YOUR_ACCOUNT_SID";
        const string authToken = "YOUR_AUTH_TOKEN";

        TwilioClient.Init(accountSid, authToken);

        var message = MessageResource.Create(
            body: ", this is a test message!",
            from: new Twilio.Types.PhoneNumber("YOUR_TWILIO_PHONE_NUMBER"),
            to: new Twilio.Types.PhoneNumber("RECIPIENT_PHONE_NUMBER")


In the above example, we first initialize the Twilio with our account SID and auth token. We then create a new message resource with the desired message body, sender phone number, and recipient phone number. Finally, we print the message SID to the console.


Sending SMS messages in ASP.NET is made easy with the help of third-party SMS gateway providers. By integrating their APIs into our ASP.NET applications, we can send SMS messages to mobile devices programmatically. Remember to sign up for an account with an SMS gateway provider, install their SDK, and follow their documentation to successfully send SMS messages.
