    Again, the unknown to us GSM module will provide full details on the connections and instructions to get it to read out.

    Most of the GSM modem will have serial port so there is no need of addition circuit, if the GSM modem has Rs232 port then you need a MAX232 at the microcontroller side.

    GSM modems usually have RX/TX pins with TTL levels, you just connect it to 8051, if the levels are RS232 you use level converter like MAX232. You communicate with the module with the AT commands. Ask Google for more.
