Sir, but I am not getting basic information.
Actually I have some doubts.
1. Can SIM 300 communicated with ATMEGA16 by RS232 DB9 only?
2. If there is some message received by SIM300, how the µC will come to know about that?
3. How to take message from GSM modem to ATMEGA 16?
Please help.....

controller has UART, and so do gsm modem... so controller and UART are interfaced through UART.... and controller issues AT commands to modem and modem does the work depending on the AT command.....

Download the AT command sheet or i will attach here... read the AT commands that you wish to implement and understand it...
connect the AT command and open hyperterminal and type the command and see the modem giving you response...
