For a mobile carrier to prevent sim swapping assuming they themselves have good enough security policies, is trivial. Most people get sim swapped bc an insider rep sends a request to a local store, or a local store doesn't do their due diligence, or even more likely, that everyone involved is incompetent, overworked, and doesn't care. The real service being sold here is the idea that in exchange for a premium, a company will train employees correctly and enforce strong security policies. which would be skipped by a normal telco because they want as much profit as possible off the top of your 30$ a month.
