I have developed one application for uploading the contact list of the mobile memory to server. It is working fine. But problem is i am not able to upload more data in one request while I am using POST method for uploading the data. I want to know that how many data can send in one request. My SIM is activated as a airlel live and another one is Mobile office. Both phone is working for the less data. please suggest me what will have to do for the same.
