Seeedstudio GPRS Shield solderpad
A GSM module for Arduino with SMS, audio and GPRS support
seeedstudio.com/wiki/GPRS_Shield_v0.9bDescription
The GPRS Shield is compatible with all boards which have the same form factor (and pinout) as a standard Arduino Board. The GPRS Shield is configured and controlled via its UART using simple AT commands. Based on the SIM900 module from SIMCOM, the GPRS Shield is like a cell phone sans the Human Machine Interface. Besides the communications features, the GPRS Shield has 12 GPIOs, 2 PWMs and an ADC.
