Even if no swap occurred, the same controls protect you next time.
What to do
- Switch important accounts from SMS to authenticator-app or hardware-key 2FA
- Set carrier port-freeze and 'in-store only' SIM swaps where supported
- Use a separate, unpublicised number for bank verification
- Set up text alerts so you'll notice signal loss instantly next time
