    Hi Everyone,

    I'm working on a project at home which deals with transmitting SMS messages using the Telit module (GM862Quad). I am using a PIC to interface with the module and I am able to transmit SMS messages.

    To transmit sms messages one has to send them in AT format which is the only way the Telit module can understand instructions. So in order to transmit SMS it was easy being that I would place the AT commands in character strings and transmit it using UART.

    However, how can I read received SMS messages? That is when someone sends an SMS message to the SIM card I'm using in my Telit module, how can I program my uC (which is in C) to be able to read the SMS sent to the sim card when it only understands AT?

    Thank you for any help provided.
