The SIM900 GSM/GPRS Shield Development Board is 100% compatible with all standard Arduino development boards and clones. It based on SIM900 module from SIMCOM, it provides you a way to communicate using the GSM cell phone network.
The shield allows you to send/receeive SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands).
The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module(They are all 2V8 logic) present on-board.
