> The majority of national governments (around 160) require mandatory SIM-card registration, which means you need your real name and personal details to sign up for phone service. And just under 20 of these also require biometrics, e.g. your fingerprints or a facial scan, with eight more countries in the process of implementing such requirements.
The biometrics part is unnerving to be sure, but anonymous SIMs or DIDs are incompatible with fraud and spam fighting efforts. If you terminate bad actors, they’ll just keep spinning up more resources.
