Expecting always on satellite connections in a lot of these places is asking for a lot.
It might be easier than having reliable power grids or running water supply. Assuming at least some of the satellite-internet projects work out (Starlink, Amazon's thing, Chinese thing, European thing, ...) all you need might be a fairly affordable (comparing to infrastructure for running water) hardware that can run on demand using batteries.
AST Spacemobile and Starlink's user experience will just require mobile phones. No adapters or base station. they'll find a way to power them, or extend signal from them. for the passport holder, that will just be client side and no connectivity necessary.
Good luck to the French dude trying to drink in the U.S. without a passport, or getting stopped by the police in Łodz and not having any valid identification on you.
Nowadays, the licenses in the EU are standardized, but at the same time, they are completely unreadable if you don't know the standard, since data fields are numbered, but not usually described in English.
