I have a MG 880 that I recently got from my office. I installed it and the installation went smoothly. I am able to make voice calls and to send SMS. But the moment I try connecting to the Internet I find that the connectiong goes through and the internet is connected but within 4-5 seconds, the connection fails and it re-connects. This happens continuously. I do not get any error message. (I was able to query the modem and it shows success on some fields and error +CME Error : 3) on other fields.
What can be the possibility and how do I solve this problem?
