Lock Out SIM-Swap Attackers for Good

Stop the same attack from working again.

What to do

Switch every important account from SMS 2FA to authenticator-app or hardware-key 2FA
Set a port-out PIN, port-freeze, and 'no SIM swaps over the phone' note on the carrier account
Use a separate, unpublicised phone number for bank verification (some banks allow this)
Freeze your credit report so identity-fraud follow-ups are blocked
Report the SIM swap to the carrier's fraud team and your national telecoms regulator
