There are two methods to read SMS:

  1. GPRS_LoopHandle.ino -> in order to recieve "+CMTI: "SM"" may be you need to send this command to your shield: "AT+CNMI=2,2,0,0,0"
  2. GPRS_SMSread.ino -> you have to check if there are any UNREAD sms, and you don't need to check serial data continuosly

I will close this issue first. If you still need to discuss it, you can open it again.
