Hey Francis, great article I agree that nothing comes free I have also searched for a lot of free SMS providers but couldn't find any. Now I am using www.textlocal.in SMS platform which has helped me in scaling up my business they have their API available for free which is very easy to use.

  If you have free credential or promotional route SMS means there is no assurance, that may be delivered or not. Also, your phone number will not listed in DND service.

how can i change the receipient no. dynamically
- Francis Susaimichael11y ago
  Get the Mobile number in a separate text box and while constructing the url, get the mobile number from the text box. So whatever mobile number entered in the textbox will be the target for SMS. Hope this helps!

Introduction:

In my previous article I explained SMS Gateways and the various schemes available for them. This article explains how to integrate those SMS gateways into an ASP.Net web application.

What a "SMS Gateway" is

A SMS Gateway allows a computer to send or receive SMS to or from a telecommunications network. This Wikipedia URL provides more detail.

Some “facts” about SMS Gateways

When I did some experimentation and Googling of SMS gateways some of the tutorials suggested use of “free” SMS gateways. But nothing worked for me. Latter I understood that “Nothing comes free”. Also most people asked the same question: “Is there any free SMS service is available to send SMS from my website?”. In my experience the answer is no. So my point here is, don’t waste your time searching for the free API. Instead, find a well-suited SMS Gateway provider and sign up with them.

What next

Well you want to send a SMS from your ASP.Net web application. So as a first step, you need to sign up with a SMS Gateway provider to get the SMS credits. Normally all SMS gateway providers provide at least 10 free SMS credits to check their services. Also they will provide details of the Application Programming Interfaces (APIs) and explain in detail how to integrate those API codes into your application.

For demo purposes I have signed up an account with mvaayoo SMS gateway providers and will use their services in this tutorial.

Markup

For the simple illustrative purposes, I’m going to develop a simple UI in a web-form as in the following. I have a textbox to accept mobile numbers and a button to send the message. That’s all!
