T-Mobile Allegedly Sells T-Life User Data as Opt-Out Prompts Keep Returning

2 articles · Updated · PhoneArena · May 28

T-Mobile is accused of selling customer data collected through its T-Life app, according to a Reddit user who said they previously worked at ad-tech firm Vistar Media.
The allegation lands after users complained earlier this year that T-Life's data-sharing prompt would not honor a tap on "Decline," repeatedly resurfacing until consent was granted.
T-Mobile says it wants device and network-usage data to build products and improve third-party advertising, and its 2025 deal to buy Vistar Media expanded that ad-business push.
Because T-Life is effectively required for account management, critics say subscribers face a forced choice between using the carrier's app and exposing more personal data.
The dispute is adding to customer backlash at a time when T-Mobile has stopped disclosing subscriber numbers, fueling questions about whether unpopular app policies are starting to hurt retention.

With its mandatory app, has T-Mobile turned user consent for data sharing into an unavoidable choice?
