Most of the time it is at home, over wi-fi. However, sometimes they chat while my daughter is walking to school. At some point, I worked in SoCal while the family still lived in the Bay Area. Very often, grandpa kept her entertained in the back of the car while the misses focused on the road ahead of her in the central valley. But the point was that while some never use video calling, others do so very often. You also wrote:With all the fibre going into homes, businesses, shops and restaurants, wi-fi is up-and-to-the-right.I don't know about you, but I rarely use those. My T-Mobile plan has unlimited data and coverage is adequate for me. It even works abroad, so unless I need high speed data I'm fine with the included 256kbps. Surprisingly, that's good enough for facetime. I predict that there will be a time where, just like POTS lines were exchanged for cellular phones, people will disconnect their cable internet and rely on 6g or 7g alone. And probably still with IPv4 addresses.
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. CB
Thanks, Sabri
