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 library has a large number of methods for communication with the shield.
The GSM shield comes bundled with a SIM from Telefonica/Bluevia that will work well for developing machine to machine (M2M) applications. It is not necessary to use this specific card with the shield. You may use any SIM that works on a network in your area. The Bluevia SIM card includes a roaming plan. It can be used on any supported GSM network. There is coverage throughout the Americas and Europe for this SIM, check the Bluevia service availability page for specific countries that have supported networks.
The shield comes in two flavors:

Arduino GSM Shield with integrated antenna, use in urban areas or when the GSM signal is stronger. No external antenna required, just plug and play.

Arduino GSM Shield with antenna connector, requires a high gain external antenna, useful when you have a poor GSM coverage.
