In reality, I'd actually just go back to a dumb phone or some Gnu/Linux phone, but I mean IF I wasn't willing to do that or it wasn't an option.
Chances are that's what I do. When I can get my own place again I'm going to have a "landline", a phone table, and an answering machine. Current social pressures already make this difficult. Most of my friends chat on different apps all day so I'm isolated from group chats, events and whatnot. So if we want to catch up or do something we need to schedule a call. So I don't often get invited to small things
