Hello.

I would look at purchasing a cellular module development kit. Telit (http://www.telit.com/) is a popular manufacturer. You can interface to it using the serial port on your microcontroller and then send and receive SMS messages.

Once The AT commands is given’ >’ prompt will be displayed on the screen.
