Is this a new SIM card or did the problem just start recently and it was working before? If it just started up, sounds like you've got a faulty connection going due to the coming loose of the parts. Lots of 3rd party stores offer fixing, and since your warranty is out anyway, might be worth shopping around. If this is a new SIM, then it might just be the SIM that's a dud. It happens sometimes.View original
