As your internet service provider, T-Mobile can see the websites you visit and apps you use on its network and may use this information to infer interests and serve targeted advertising.
Unlike website cookies, network-level monitoring is invisible to consumers and captures all online activity on T-Mobile's network regardless of browser privacy settings, representing a uniquely invasive form of data collection.
Network-level data collection by telecommunications carriers implicates FCC open internet and CPNI rules, CPRA sensitive data frameworks, and FTC unfairness doctrine; the use of deep packet inspection or similar methods for advertising purposes without meaningful consent has been a subject of prior FCC enforcement and should be flagged in due diligence reviews.

T-Mobile collects extensive personal data including precise geolocation, network browsing activity, CPNI, biometric data, and financial information, and uses it for targeted advertising as well as sharing with affiliates, partners, and third-party data brokers. Consumers' data may be sold or shared in ways that affect their privacy and financial profile, and some data sharing persists even after account cancellation due to legal retention obligations.
