I've had my htc inspire for 10 months now and everything has been fine, until today. This morning my phone shut down by itself and when I turned it back on "no sim card" and "no service" errors came on. My brother and I are both with att and he has service right now. Also, I just checked my sim card with an older phone and it works fine. I do have the mobile insurance, do you guys think it will cover my phone? Or any ideas on what the problem could be?
