The SIM800L Arduino Library is a simple and easy-to-use library for the SIM800L module, allowing for quick and efficient communication with the module using the Arduino platform.

Enables GSM/GRPS network connection using the GSM/GPRS modules. Use this library to make/receive voice calls, to send and receive SMS using Generic GSM/GPRS modules, such as u-blox SARA-U201 module.This library also allows you to connect to internet through the GPRS networks. You can either use Web Clients and Servers.
