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.
When you're in the USA is the VoLte greyed out?
