Stop SIM-Swap Attacks on Your Phone Number

Attackers port your number to steal bank codes — carrier PINs, authenticator apps, and number hygiene.

  1. 1. Set carrier port-out protection now

    Call your carrier (or use their app) and add a port-out PIN plus Number Lock. This single setting blocks most SIM-swaps — attackers can't move your number without the PIN even with your personal details.

  2. 2. Move MFA off SMS everywhere important

    Switch banks, email, and crypto to authenticator-app codes. SMS MFA is exactly what SIM-swappers harvest — every account still on SMS is an open window.

  3. 3. Shrink your number's blast radius

    Use a Google Voice or secondary number for public listings, shopping, and social media. Your real mobile number should appear in as few breaches and forms as possible.

Guide FAQ

Sudden No Service plus password-reset emails you didn't trigger. Contact the carrier immediately from another phone — your line is in someone else's hands.
It stops physical SIM theft, not social-engineered ports — attackers convince carriers to move eSIMs too. The carrier PIN is still the real defense.
