A while ago I had a discussion with my friends that it is possible that in the future if 5G is sufficiently cheap, smart tvs come with a 5G SIM so they can force ads and updates even if you refuse to connect it to WiFi. I wonder if this will ever be a real thing. Either 5G, 6G or whatever comes next.
Real 5G can’t penetrate walls so I doubt it. AT&T 5G is really 4G so that could be added to tv’s easily.
