Phone Number and SIM Swap Lockdown
A carrier and account-security workflow for SIM swap risk, port-out fraud, phone-number takeover, SMS MFA exposure, and suspicious service changes.
- Stabilize carrier access, account PINs, port locks, device status, and phone-number recovery.
- Review email, banking, cloud, social, crypto, and phone-carrier accounts for takeover paths.
- Move critical accounts toward app-based MFA, passkeys, hardware keys, or stronger recovery methods where supported.
- Document carrier support interactions and suspicious service-change evidence.
