Product Description

This module is a GSM/GPRS shield for the Arduino and based on the SIM900 Quad-band GSM/GPRS module. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands).  This shield has been tested successfully in Costa Rica to work with the ICE, Claro and Movistar using the Arduino library below.

This shield comes with an antenna and extension interface cable.

The module can be powered on and off via software control.

3.5mm sockets for microphone and earphone interface.

Features:

Quad-Band 850/ 900/ 1800/ 1900 MHz
GPRS multi-slot class 10/8
GPRS mobile station class B
Compliant to GSM phase 2/2+
Class 4 (2 W @850/ 900 MHz)
Class 1 (1 W @ 1800/1900MHz)
Control via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands)
Low power consumption: 1.5mA(sleep mode)
Operation temperature: -40°C to +85 °C

Code:  The example code in the default GSM library is the best way to get started (do not install alternate GSM libraries until you know what you are doing...they can change the configuration of the SIM900).

ADDITIONAL NOTE:  This shield has been successfully tested with the new GSM library built-in to Arduino 1.0.4+ (thanks to crispitico for this tip).  Make sure that the baud rate is set to 9600 and the jumpers are set like this:
