Quoting Beausoleil

Sander, The USA SIM card doesn't work in Europe. The number is broadcast on a different bandwidth than used there. The USA uses two different bandwidths for broadcasting than most of the rest of the world for some stupid reason.

The different bandwidth applies to the handsets, not the SIM cards.

Historically, and going from memory, much of the world is on GSM900 and 1800, while north America is on GSM800. But nowadays I think handsets are all quad band to cope with any of it.

Your US phone provider SIM card should work fine in a French phone, it's just a question of whether it's a nano SIM, micro SIM, etc. Modern smartphones all tend to be nano SIM now I think.

I have an old quad band phone that I can bring. We'll try it and see what happens. All the phones use the nano SIMs. The battery has had it in the old phone and can't be replaced but it works when it's plugged in. I use it with a bunch of recipes I've saved on it.

Hope it works. Right now I'm more worried about France closing to Americans than phone problems. We are both vaccinated but they change the rules every day and although we applied when they opened to foreigners, we still don't have our Health Passes. This is an interesting time to travel . . .
