In the EU this is trivial to bypass via the Roam-like-at-home policy and pre-paid Eastern European sim cards. In the US one is able to order a sim card via mail and while one has to submit PII I don't suspect it is checked rigorously. (versus EU photo ID schemes that cannot be fooled without significant effort and criminal energy)

So here's two of the worlds largest economies out - I can't imagine it's much harder in the "rest" of the world.
