Android Version: 2.2 FroYo Network: O2 UK Taskiller Used?: No Issue: Here's a weird one for you. I got my HTC Desire last November and it's been perfect up until now. As of the last couple of days my phone has just lost all of it's signal. The only places that I can get signal are in big towns and on the motorway (obviously I'm not using the phone whilst driving!). Anytime I go home or to a place where normally I'd at least have 2 bars I have nothing. Even when I do get signal in the town I can't make calls and can barely send texts as they keep bouncing back. I thought I'd give it a little while just in case 02 was being dodgy but still nothing. If I manually try to connect to 02's network it comes up saying either that no network could be found or that my sim card cannot be registered on the network. My sim card works fine in other phones! I'm at a complete loss here, any help would be fantastic! Cheers.
