GSM SIM900 Library for Arduino

Enables GSM/GRPS network connection using the GSM/GPRS modules. Use this library to make/receive voice calls, to send and receive SMS using Generic GSM/GPRS modules, such as u-blox SARA-U201 module.This library also allows you to connect to internet through the GPRS networks. You can either use Web Clients and Servers.
