Even before mobile phones, there where paid phone services, some about sex but some just to talk to people, that got people addicted.
I remember something called “the party line” where you would dial a paid number and you would be connected to sort of a group chat with some other people.
Some people even got in debt because of massive phone bills.
We also don’t have the grid support for everyone to start charging at home. At least not where I live. At the moment even solar panels are becoming a problem, major peaks during sunny days, where energy prices even go negative and people with dynamic energy contracts turn panels off.
