Question
My phone has been working fine for a year but a week ago it started to not read the SIM Card. Now it will not register it at all. It's a LG CU920 and the SIM Card is at&t also what's the problem?
There is likely not a problem with your SIM card. Take out the SIM and wipe off the contacts with a soft cloth (no water or other liquids) and then put it back into the device. When you turn it on again, it likely should work. If it doesn't, then the issue is most likely with your phone, NOT with the SIM card. It's possible that the antenna of your phone may be damaged. If your phone is pretty old, that could be the problem. If you are still under contract for that phone, take it into AT&T and see if they can have repair look at it. If it's older than 2 years, I would suggest getting a new phone. I hope this helps. Thanks. DebiN
