i have found different solution to resolve that using vodafone sim card data posting successfully. when using airtel simcard send data using HTTP/1.1. when i'm sending data like HTTP/1.1\r\n but data modified in controller and Send Data too gsm is HTTP1.1\r\r\n. in idea sim card internet connection is not established properly. and disconnect automatically. — Kalarav Parmar, Jan 05 '17 at 12:08

A solution is very different from my thinking actually in this GSM module UART interfacing used. So, whenever I want to communicate to GSM send the command over UART to GSM. there is some unexpected behavior I have found when I'm sending data like HTTP/1.1\r\n but data modified in the controller and Send Data to GSM is HTTP1.1\r\r\n\n. in idea sim card.
