Hi henary

Your problem is not so clear but from what i understand ...

1. Your First task is to read for an incoming SMS.
a) poll for it with AT+CMGS=<Slot Number>
Slot Number will be from 1 to 30 or more depending on your SIM capacity.

or you can enable unsolicited incoming SMS indication with AT+CMTI command.

the read message you can further process for your particular command header and then you can form a report in ascii and use

AT+CMGS=<mobile number> modem replys <
then you pump your ascii message and end with ctrl+Z or 0x1A.


just go through these commands if still having problem i will send you a log file with the command sequence.
