The Sim800C GPRS/GSM Shield with Antenna provides you with a way to use the GSM phone network to receive data from a remote location，and it is compatible with all boards which have the same form factor (and pinout) as a standard Arduino Board. This shield can also be applied to DIY phones for calling, receiving and sending messages, making GPS trackers or other applications like Smart home, etc.

SIM800C GPRS/GSM Shield delivers GSM/GPRS850/900/1800/1900MHz signals for Audio, SMS and GPRS Service. Also, it runs at the low power consumption of about 0.6mA in sleep mode but acts compliant to GSM phase 2/2+: Class 4 (2 W @850/ 900 MHz), Class 1 (1 W @ 1800/1900MHz) with a two-in-one headset jack.

What’s more, to make your project more flexible and efficient, we have prepared two different antennas for you. One is the traditional GPRS antenna which is more sensitive while another one is an onboard antenna which is more compact and easy to install.
