In this post I am writing how to send a GET request using GSM Module with AT commands. It should work with any module and has been tested to work with Sim800 series (SIM800C-DS , SIM800A, SIM800H, SIM800L, SIM800C, SIM800 etc) and Sim900 series (SIM900, SIM900A, SIM900D, SIM900B) of modules from simcom.
