To generate OTP refer

Generate Unique Random OTP (One Time Password) in ASP.Net using C# and VB.Net

For sending SMS there is no FREE API. you need to buy SMSs from a licensed SMS company

Please help me to do this using ASP.Net c# with free privilege sms sending service.

As mudassarkhan mentioned, most of SMS sending services/APIs are not free. If possible, you can try Twilio, or search for more SMS services/APIs.
