Turn on your carrier's port-out lock

Stops your number from being moved (ported) to another carrier without you. At AT&T it is part of Wireless Account Lock, which AT&T calls a free security feature; at Verizon, Number Lock stops anyone from generating the transfer PIN a port needs.

How to do it

  1. AT&T: in the AT&T app, tap the person icon, choose Wireless account lock and swipe to lock (prepaid: Profile & Settings › Account Info & Preferences › Wireless Account Lock). Only users with primary or secondary access to the account can change it.
  2. Verizon: sign in to My Verizon with Account Owner or Manager access, go to Account › Account settings › Security settings, and turn on Number Lock for your numbers.
  3. Other carriers: ask whether they offer a lock on number transfers and SIM changes.
  4. Before you move your number to a new carrier yourself, turn the lock off first.
