I am now working on a project in which I gotta send SMS from a GSM or, CDMA module by a Microcontroller device when a sensor have positive response.( I can't use PC there because my device has to be portable)

hi shakib,

its pitty easier when you understand the GSM and its commands. first of all you read the AT commands for the GSM modem, and then you test with your PC com port terminal. so only you could understand the working principle of the GSM.

After you getting thorough in the GSM, you go ahead with your Microcontroller. by passing the commands from the controller to GSM, it will work according to the commands.
