This might be stupid but I never really grew up in a time when people used home phones. My family, at least. The other day I realized there was a phone jack behind an end table in my house that I hadn’t noticed before and started thinking about it and having a lot of questions. Are these phone jacks a public service or utility, like water and electricity? Where do the jacks even go to? do they have a phone number already assigned to them or something? Like if I wanted to, could I just plug any old phone into the jack and have it work?

In most countries they are exploited by private companies, and you do need a subscription. Furthermore, you often pay an amount per minute- more if you call outside of your area, and more than that if you call to another country.
The copper lines go to a phone central, where it will be redirected. There are probably some in-depth videos on how that works exactly.
