T-Mobile US, the wireless carrier majority-owned by Deutsche Telekom AG, discloses in its Privacy Center that it collects a broad range of data—including precise location, biometric identifiers, and sensitive account data—and uses cookies, mobile advertising IDs, and third-party ad networks to support targeted advertising, as described in its own privacy notices. The company's regulatory record includes a 2024 FCC consent decree over data breaches spanning 2021-2023, a separate 2024 FCC fine for selling access to customer location data to aggregators, and a 2022 class action settlement tied to a 2021 breach affecting more than 76 million people. T-Mobile's corporate ownership is disclosed in SEC filings, which identify Deutsche Telekom as the controlling shareholder with majority voting power.
