This GSM/GPRS module is .NET Gadgeteer compatible, which uses the .NET Micro Framework to make writing code for your device as easy as writing a desktop, Web or Windows Phone application.
This module carries SIM900, which is a quad-band GSM/GPRS engine. The standard industrial-level interface makes it easy to configure via AT commands. 
Through this module you can do almost everything that feature phone does. Imagine that every morning, your "private robot secretary" calls your phone and say "good morning". It will be really cool!
