A MVNO not on T-Mobile that used Passkeys for 2FA and the only way to legitimately port a SIM off the service requires a scheduled in-person interview would be a solid business. No marketing, all word of mouth from VIPs.

Would you pay $5k/year for this?

Does that actually work? Like if you're an MVNO aren't you basically just reselling the product of the actual network operator so they can still rug your users?

I have seen Efani recommended by a few people in the crypto security community recently (like @zachxbt here). I haven't used it and can't vouch but I think it's basically what you describe. https://twitter.com/zachxbt/status/1743115285148885489

SIMs need an onchain component that will allow users to use multisig recovery, easy portability, etc.

It is NOT possible to secure any SIM-based telephony system against number porting. One layer up from such an MVNO is an aggregator with humans that can be bribed to change the routing for that number. The solution is to upgrade the telephony network with e2ee and the mobile number secured using ENS and a private key.

The problem could be easily solved with a signature from SEC the entity. Like so by valid3.id. === https://sign.valid3.id/#/hsHSD6P0
