To prevent getting tracked, T-Mobile customers need to opt-out of a data sharing program by April 26th
Privacy groups are concerned that by comparing data that has been collected, T-Mobile subscribers still can be identified. Aaron Mackey, a lawyer for the consumer-privacy advocate Electronic Frontier Foundation says, “It’s hard to say with a straight face, ‘We’re not going to share your name with it.’ This type of data is very personal and revealing, and it’s trivial to link that deidentified info back to you.”
To opt out of the program, T-Mobile subscribers should open the T-Mobile app, tap the MORE tab and select Advertising & Analytics > Use my data to make ads more relevant to me. Use the toggle switch to turn off the setting which will then show a gray color. Or, you can go to MyT-Mobile.com and click on the drop down called My account. Follow these directions: Profile, Privacy and Notifications > Advertising & Analytics > Use my data to make ads more relevant to me. Turn the toggle off to opt-out of the program (it will turn gray).
Metro subscribers can open the mobile app or go to https://www.metrobyT-Mobile.com/iba. To use the latter web address, you must be on a mobile browser. Using the app or the mobile website, visit the Account tab > Network and Location Settings > Use my data to make ads more relevant to me. Turn the toggle off (gray) to stop. Sprint customers need to open the Sprint website (https://www.sprint.com/en/login.html). Tap on Visit My Account > Preferences, and scroll down to All about my account. Select Manage advertising and analytics preferences; Select the line you would like to update, then click on Use my data to make ads more relevant to me. Tap on the ‘OFF’ radio button to opt out.
AT&T automatically enrolls its wireless customers into the basic Relevant Advertising program. You can opt out by heading to your browser and typing in https://www.att.com/cmpchoice. At Verizon, you can opt out of the Relevant Online Advertising program, by logging into the My Verizon app. Go to Account Settings > Preferences > Manage privacy settings and select the phone number that you want to opt out with. The third toggle down is for Relevant Mobile Advertising. Toggle the switch to off and you have opted out. AT&T and Verizon use a similar method that pools user data based on presumed customer interests.
