title: How to develop my own sms Gateway?
body: <p>I intend to develop an SMS gateway in c#, but i am doubtful about it's feasibility, because my initial research had shown that an SMS gateway had to cover for protocol differences.</p>
  
  <p>So what exactly a gateway had to do, further if i use SMPP, so is it possible to send/receive SMS to/from any number in the world by simply using SMPP ?</p>
