AT+CNMI=1,2,0,0,0 Set how the modem will response when a SMS is received
AT+CMGF=1 To format SMS as a TEXT message

i would like to know what is the command to Read the GSM SIM 800 module settings . I would like to confirm the command i gave to set the module to Text Mode has been saved .
are there any other settings (initialization ) related to PDU mode as the Messages being Sent from the same GSM are recieved in Text Form in my Mobile.
hi , actually the code works fine with sim300. but problem is with only sim800.
at+cmgf=1 command i have sent to module from microcontroller got ok response from the module but still same problem is there.
i solved the problem . the problem was my mobile sms settings(text messages ) input mode was in unicode mode. i changed it to gsm aplhabet/automatic it works fine now. the problem was not with gsm module .
