Dear All,Activated the EGPRS Connection on my BSNL Post Paid Mobile Connection but EGPRS is not working. The connection gets established for some time when I can browse the net but getting disconnected very soon.The normal mobile signal strength is also dropping momentarily.I am using the Nokia 5800. I stay in Central Kolkata (PIn: 700 012)I have tried the same BSNL SIM in other phones but the signal strenth is not dropping. When I am inserting a Airtel SIM in my Nokia 5800 it is working right.(So my Handset is not faulty)Very confused - Where is the problem ??Handset & SIM both are OK. But the particular SIM does not work with the Nokia 5800. :huh:Contacted BSNL Customer Care but they said they are helpless as usual.Kindly help and suggest.
