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.
AFAIK, that's not correct. T-Mobile does provide IPv4 *on the device* but translates it to IPv6 (464xlat) before the packets leave the device for the network. Regards, Bill Herrin -- William Herrin bill () herrin us https://bill.herrin.us/
