      i am using PIC30F microcontroller for communicating with GSM modem.I am using Quectel M95 modem.When i am sending reading command(AT+CMGR=1<CR><LF>) to the modem i am getting <CR><LF>OK<CR><LF> as a response.

CMGR response

From your hyperterminal (dont connect to microcontroller) just type AT+CMGL="ALL",   so that it will display the list of messages in your simcard. If it lists type AT + CMGR = 2 (the message number you want to display) and check it.
