Are any providers offering an opt-in SIM freeze of sorts with some kind of enhanced authentication in order to unfreeze? Wouldn't such a feature/service easily prevent the SIM-swap risk? I don't know how easy this is to prevent regarding the infrastructure (do networks detect a SIM-swap via change in host IMEI?). I understand the article describes a rogue employee but it seems to me that an added layer for such a service could easily prevent unauthorized access.
