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.

I believe it’s VoLte compatible.  I have the option to “Use mobile data during calls” which I think is VoLte.
