I meant like the elderly might still be using a dumb phone, but not a CRT screen or analog connection.

Why couldn’t you turn off 3G on that old phone via that same hidden menu? Or how come the phone didn’t even recognize that it can fall back to 2G…

Well, they shouldn’t turn it off any time soon, just like they don’t turn off analog radio. TV is one I can understand where turning off old methods makes sense, because people upgrade their TVs and use IPTV/SatTV/cable TV much more likely anyway.
