Suddenly cannot connect to network

I have a pay as you go legacy SIM in an older Moto G4 Play Android phone. I powered it off in the middle of last week and powered it on yesterday.  It will not register to the T-Mobile network here in coastal Los Angeles.  It shows “Emergency Calls Only”. My wife’s phone connects to T-Mobile from the same location, also with a pay as you go legacy SIM.

Scanning for carriers, it finds T-Mobile and AT&T.  Selecting T-Mobile manually causes it to try to register for a while and then say my SIM does not allow connecting to the T-Mobile network.  Moving the SIM to a different phone shows the same situation.  I inspected the SIM and do not see any problems with the contacts, and no difference when I tried gently polishing them with a pencil eraser.

Can a SIM fail this way?  I think it is at least 10+ years old. The phone doesn’t report any issue like “SIM not detected” that I have seen years ago with other SIM-related problems...

I got a free replacement SIM at my local store and that fixed it.

Yes, if I swap them the problem follows the SIM.  Both phones connect normally with her SIM.

The T-Mobile tech support guy at 1-800-937-8997 said my account was in normal status and just suggested I go to a local store to have the SIM checked or replaced.

YES! Try switching SIM cards with your wife. If your SIM doesn’t work in her phone, it’s the SIM. If your SIM does work in her phone & her  SIM doesn’t work in your phone, it’s your phone! :open_mouth:

Have you tried swapping sims between phones to see if it’s a phone or sim card issue.

Sims cards can fail so you may need a new one.
