The Arduino GSM Shield connects your Arduino to the internet using the GPRS wireless network. Just plug this module onto your Arduino board, plug in a SIM card from an operator offering GPRS coverage and follow a few simple instructions to start controlling your world through the internet. You can also make/receive voice calls (you will need an external speaker and microphone circuit) and send/receive SMS messages.

The GSM Shield allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages. The shield uses a radio modem M10 by Quectel. It is possible to communicate with the board using AT commands. The GSM library has a large number of methods to communicate with the shield. The shield uses digital pins 2 and 3 for software serial communication with the M10. Pin 2 is connected to the M10’s TX pin and pin 3 to its RX pin. The modem's PWRKEY pin is connected to Arduino pin 7.

The M10 is a Quad-band GSM/GPRS modem that works at the following frequencies: GSM850MHz, GSM900MHz, DCS1800MHz and PCS1900MHz. It supports TCP/UDP and HTTP protocols through a GPRS connection. GPRS maximum data downlink and uplink transfer speed is 85.6 kbps.

To interface with the cellular network, the board requires a SIM card provided by a network operator. See the getting started page for additional information on SIM usage.

The most recent revision of the board uses the 1.0 pinout on rev 3 of the Arduino Uno board.

To use this board you should note that:

  • Requires an Arduino board (not included)
  • Operating voltage 5V (supplied from the Arduino Board)
  • Connection with Arduino Uno on pins 2, 3 (Software Serial) and 7 (reset). See these notes for working with a Mega, Mega ADK, or Leonardo.
  • This version has a connector for an external antenna
