What is T-Mobile Port Out Protection?
T-Mobile publishes this under two names — Port Out Protection and Account Takeover Protection — for the same free feature: it blocks unauthorised users from moving your lines to another wireless carrier. It is available on T-Mobile Postpaid, T-Mobile Prepaid, T-Mobile for Business and Metro by T-Mobile.
Two details matter. First, it must be added to each line on the account individually — protecting one line does not protect the rest. Second, removal is deliberately harder than addition: for postpaid, the Primary Account Holder has to turn it off, and prepaid line users who ask to remove it must pass an extra account security step.
You need to be the Primary Account Holder, or hold Full Access permissions on your line, to add it. Business and government accounts are asked to contact T-Mobile rather than self-serve, because of line volume.
Important: Because it is per line, adding it once is not enough on a family plan. Check every line.
How do I do it?
- Sign in to the T-Mobile app or T-Mobile.com with your T-Mobile ID.
- Confirm you are the Primary Account Holder or have Full Access on the line.
- Open the account security settings and choose to add Takeover Protection.
- Repeat for every line on the account.
- For a business or government account, contact T-Mobile to have it applied.
