The new toggle can be found in T-Mobile’s “Privacy Center Dashboard”. You can click here to go straight to it, or follow the steps below.
Login to your account either on the web or in the app as a full permissions user (typically the account holder’s main line).
On desktop/the web, click “Edit profile settings” at the top. On the app, tap “MORE” at the bottom of the app and then “Profile settings”.
Scroll halfway down the list and choose “Privacy and notifications”.
Find “Privacy dashboard” and open that.
On this page, you’ll have all the privacy opt-out options. Take the time to opt out of all of them, if you haven’t already and want to. Otherwise, scroll down and find the new “Profiling and automated decisions” section, as shown below this list, and disable it.
If you have more than one line, go back to the top, and choose “Manage a different line >”. You’ll need to toggle this for each line on your account.
