SIM900 Quad-band GSM/GPRS Shield for Arduino UNO/MEGA
The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name ). It is possible to have multiple software serial ports with speeds up to 115200 bps.
SIM900 GSM/GPRS shield for Arduino - MyDuinocom
The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07. 07 ,07. 05 and SIMCOM enhanced AT Commands).
