Given a lot of places now want traceable sim, I wonder is this legal in some countries. Or it just happened the global is meant countries that does not require ID to register phone sim?
Most of the travel eSIM services resell a SIM from a carrier in country A that has a favourable roaming agreement with a carrier in country B (where you want to use the service).
I just signed up for the Firsty app from the UK, and the eSIM it gave me appeared to be issued by Play Poland (https://www.play.pl). This then roamed on the EE network in the UK (https://ee.co.uk).
As the SIM is roaming, there's no practical way for any KYC requirement to be enforced. This is the same as if an AT&T customer in the USA visited India (for example) and roamed onto an Indian network.
Some of the eSIM providers like Airalo do offer certain plans with KYC requirements, but that's only for a minority of countries.
