GSM Module.

SIM800L is a miniature cellular module that allows for GPRS transmission, sending, and receiving SMS. Low cost and small footprint and quad-band frequency support make this module the perfect solution for any project that requires long-range connectivity.

The SIM800 series module supports the HyperText Transfer Protocol application. Which provides a mode to the alternative HTTP server. The basic application contains GET, POST, and HEAD methods; it also supports proxy servers, redirection, and broken transfer resuming functions.

The SIM800 series module supports File Transfer Protocol applications. Which provides a mode to interact with the FTP server. The basic application contains GET, and PUT methods, it also supports the broken transfer resuming function. The PUT method supports APPE, STOR, and other modes.
