title: Issue related to APN names
body: <p>I am using simcom900 modem,I am successfully able to establish GPRS connection and send data from my module to server.I am using 2g Airtel SIM and I have given APN name as "airtelgprs.com".I have also tried by giving different APN names which are not related to airtel network then also I could establish connection and transfer data to server.</p>
