The SIM800L is a micro SIM low cost GSM/GPRS Development Module. TheModulesupports TTL communication and hence can easily communicate with Microcontrollers without the need of additional data converters like MAX232. The module also supports antenna with IPX connector.

SIM800Lmodule can be used to make a cell, receive a call,send and receive text messages, connecting to internet through GPRS, TCP/IP, etc. Moreover themodule supports quad-band GSM/GPRS network,so it can operate globally.

The SIM800L GPRS GSM Module is compact in nature and hence can be directly used on final Designs. The on-board LED indicates the connection status of the Board, when there is no signal the LED flashes quickly and when a signal is established it flashes slowly.
