Description:

The GPRS Shield is based on SIM900 module from SIMCOM and compatible with and its clones. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve 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 onboard.

Be careful: Insert the SIM card into the SIM card holder by gently press down the SIM card holder!! Don't force up, otherwise you could damage the card slot!!
