title: Send and Receive SMS from PHP Application
body: <p>I want to make a Facebook like SMS sending and receiving service. Are there any PHP API to do that? I want to use a specific number like Facebook.</p>
  
  <p><strong>Note</strong><br>
  Sending SMS through E-mail is possible but how can I receive SMSs through my PHP application? I am searching for a free PHP API without any external hardware to do that. Is it possible?</p>
