So i purchased a ATT HTC inspire 4g about a month and a half ago. It concerned me that upon the process i did not recieve a new SIM card but my old scraped up SIM card from about 3 years of use was slipped right back into the phone. I recently spent a night listening to music on my phone (w/ headphones) and when it came time to retire for the night I plugged my phone up to charge and i was out. That morning i didnt notice anything particularly different about service or my SIM not being recognized or anything but about 2 hours later while driving, i was waiting for a call. Then upon closer inspection i noticed I had no service whatsoever on the device and the SIM was not being recognized even though it WAS in the phone. I took out the SIM card/Battery/SD chip multiple times, turning the device on and off for hours at a time. I tried to mess with the Airplane mode..nothing. Uninstalling recent apps...nothing. Restarting it time and time again, wiping copper contact areas multiple times and still nothing. Wifi still works and connects well. Has anyone experienced this same problem. what did you do? Or to anyone else what would you recommend to take as a next step?
