SIM800C GSM GPRS module is a miniature GSM modem, which can be integrated into a great number of IoT projects. You can use this module to accomplish almost anything a normal cell phone can; SMS text messages, make or receive phone calls, connecting to the internet through GPRS, TCP/IP, and more! To top it off, the module supports quad-band GSM/GPRS network, meaning it works pretty much anywhere in the world.
The Sim800C GPRSGSM 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 GPRSGSM Shield delivers GSMGPRS85090018001900MHz 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 22+ Class 4 (2 W @850 900 MHz), Class 1 (1 W @ 18001900MHz) 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.
The main drawback of this module is working on 3.7 to 4.2 volts so you cannot power it directly through Arduino or Raspberry Pi. Moreover, the sim800C GSM and GPRS module require up to 2 amperes current so accordingly, design your power supply. You can use a 3.7-volt lipo battery to directly power the GSM module.
