Socket connection issue with different types of sim cards

I am using sim808 module and i have two different types of sim cards.

  1. Airtel sim
  2. bics sim for things

First i kept Airtel sim card in my hardware and tested. that hardware is working fine it is sending data to the server and getting response from the server.
Data is sending in TCP protocal with GET method.

I kept bics sim card in my hardware and tested. that hardware is working fine it is trying to send data to the server but data is not reached .
Data is trying to send in TCP protocol with GET method.

Hi Sateesh

I don’t have experience with Embedded AT commands.
Also, Please ask specific questions, People wont have time go through your code. If you have ask short doubts we can answer.
And you should insert code directly in edit window instead of linking
