It has 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!
