No it won't. Anonymous SIMs were already wiped out in large areas of the world. The way KYC works is you need to know the "beneficial owner" i.e. ultimate owner of an asset. The bazillions of 5G sims we're promised will all be tied to a strongly verified corporate identity and to get on a network will require you to present ID if an individual, or do corp KYC if a firm (which will in turn require the heads of the company to do personal KYC to establish beneficial ownership information). Remember, this isn't even new for many countries.
