Problem with OPPO phone in USA
I have a dual-sim OPPO FInd phone, and I have a USA SIM card with T-Mobile. For the last couple of years I've traveled back and forth to the UK, switching between US and UK sim cards with no trouble....

Does that imply that my phone isn’t going to ever work with T-Mobile for voice calls?
Yes. As of last year, VoLTE is now required to make and receive calls on the T-Mobile network. No compatible VoLTE on your device means the device is no longer compatible with T-Mobile USA or any US based cellular provider's network.

Thanks so much for taking the time to think about this and send really informative replies. I have spent so much time (including multiple phone calls with T-Mobile tech support), and made zero progress. It seems that you've been able to diagnose the problem using only my minimal and not-well-informed descriptions of the problem. Many thanks for that.
