how to connect GSM Modem with any microcontroller ?


plz help me.
 

You have to use serial communication between MCU and modem. You send AT commands to configure and control modem. Most of modems work at about 3.7V so use low power MCU or level translators between MCU and modem. There are a lot of available schematics on internet about this.
