I’m really glad that I had the experience of travelling during a time when telephone cards were still a thing. I caught the very tail end of that era.
When abroad, I would go to a local corner store and purchase a little plastic card with maybe 10 or $20 on it. I’d go to a payphone and your dial the number on the card, it would say how much balance I had left, and then I could call any number in the world for a certain rate per minute.
I’m really glad I had that experience. The disconnection was liberating.
