Hi, I really hope somebody might be able to help me here. I got my HTC DHD on Tuesday and it was working fine till today. For the last 4 hours it shows 'no service' (i.e. no network coverage/no phone). Everything else is working fine. I've tried switching my SIM card to my old HTC HD and it worked fine, I could make/receive calls. I also tried airplane mode on/off, restart, taking out the battery, plugging to pc, plugging into power socket, even hard reset - the problem still exists, like the phone module is off for some reason. WiFi works fine btw. All settings look fine. The phone doesn't have a scratch on it, brand new, never been dropped. I'm really upset by this issue - the phone is just 3.5 days old and such an issue appeared. Doesn't look promising ( Any suggestions apart from the obvious 'return to the shop and wait for ages to get it repaired'?
