am facing a serious problem with my blackberry curve 8520. My mobile network is based on edge. And since 2 days GSM is shown at the place of edge and if I make a out going call, it shows " the call is Failed" and even messages can't be sent. And I get a incoming calls with out any problem, when I get a incoming cal GSM is changing to EDGE and then I can make a outgoing cal..In order to make a out going cal from my mobile I should receive a incoming cal first to change GSM to EDGE. And some times edge changes to SOS and no network is activated. Please solve my problem.

The first thing I'd do is to get a free SIM card swap from Airtel.
