... always wondered if the cell phone requirements are not (also) tied to then wanting an actual, physical, person behind each account - as in most EU jurisdictions each SIM card is tied to an actual ID.-
In many EU countries, you can buy sim cards from some vending machine, in a grocery store or places where you can buy international telephone cards. No ID required. But phone plans are often tied to your home internet.
There are several countries that didn't buy into the madness of registering SIMs, luckily. Most strangely, the UK, the master of CCTV. Apparently they realized that it's a useless measure and will just anger the people.
