This is a great and very neatly organised list.
Thank you for this amazing resource. A lot of the time I don’t know a service exists (or it’s alternatives) until I’ve done a ton of research (or realistically just suffering without it), so this provides a great starting point to see what might exist to solve a gap.

The countries in question can vary the process greatly.
I live in a country where I pay my monthly charge for my sim, and I hold a number in another country where if you have a positive balance on a prepaid number, even if it’s not connected, it stays active.
I also believe so long as it’s connected (even via roaming) most countries won’t shut it off.
