You are not using ipv4 today.

The scenario you describe, using facetime (iOS) on T-Mobile US, you are not
using ipv4 on the device.  T-Mobile does not assign ipv4 addresses to iOS
or Android devices in default scenarios, has not for years.

If the far end of your facetime call is v4-only, you may need nat64 in the
cloud.... but otherwise no v4 in the flow, and no v4 on the device.
