The usual: My account password, two factor auth, account security PIN. Additionally, an SMS is sent to the number that’s being transferred giving a chance to block (with a timeout to auto-approve if the device is lost).

I haven’t explored it but I would assume there is also an optional “high security mode” lock — something like requiring account changes to happen in-store with physical ID.

How is having to type into an app your account password, do two factor auth, type account security PIN a better UX then pulling out a physical SIM and putting it into another phone?

More secure at least, if my phone is lost or stolen they can't just take the SIM out and rack up international charges on my account, etc.

Because I didn't have a physical SIM. The phone was lost.
