Learn about SIM800L GSM GPRS Module along with its Pinout, Antenna & Power Supply Selection, Wiring, AT Commands & Code for Sending & Receiving Call & SMS.

We will hook up the SIM800l module with Arduino using the Soft Serial library. We will connect the Hardware serial port to the computer to debug and print messages. Note that the module requires voltage in the range of 3.17 to 4.4v . If proper voltage is not provided the module will give under and over voltage warnings.

Nov 26, 2015 · SIM800 and SIM900 are both quadband: 850, 900, 1800 and 1900 MHz. SIM900 is older type (now obsolete), predecessor SIM800. SIM800L has FM on it. SIM800F is pin compatible to SIM900 module. SIM868 is dual sim version with GNSS and small form factor. SIM800 use same AT commands as SIM900 + few new.
