If you need GPRS Shield, please purchase EFCom 

4 Frequency GPRS/GSM Module-EFCom Por is an ultra compact and reliable wireless module. It is a breakout board and minimum system of SIM900 Quad-band GSM/GPRS module. It can communicate with controllers via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands).

This module supports software power on and reset. EFCom Pro is based on SIM900 4 Frequency GPRS module. The GPRS is configured and controlled via its UART using simple AT commands. Just connect on the Arduino/AVR/ARM/FPGA/CPLD... board, you could easily use AT command to control it. EFCom Por can be connected to PC via FT233RL, and recommend our FT232 Bee adapter.

EFCom Pro IO List:

GND , +5V , RX , TX , PWR , RST .    

Connect with  FT232 Bee adapter.


There are a AT Command tester written by Surya for you. It easy use it and you can learn AT command quickly. AT commands are the primary software interface for wireless modules. AT commands are defined as part of 3GPP standard under 3GPP TS 27.007. That implies that all the wireless modules that operate on cellular networks are required to support AT commands.
