T-Mobile collects and may use or share your Customer Proprietary Network Information (CPNI) — which includes details about how you use your phone service — for certain purposes. You have the right to restrict some of this sharing.
This analysis describes what T-Mobile's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
CPNI sharing practices define the scope of customer data available to T-Mobile's business operations and marketing functions. The operational significance lies in how this provision structures data flow across T-Mobile's corporate structure and to external service providers, which directly affects the scale and scope of data processing the customer authorizes.
The updated terms expand T-Mobile's authority to suspend or terminate service by explicitly including theft and unlawful conduct as grounds for suspension or service denial, beyond the previously stated prohibited uses. The agreement also clarifies that price commitments embedded in Rate Plans do not automatically extend to new technologies, features, or services unless expressly stated, meaning customers cannot assume their locked price applies if T-Mobile introduces new offerings. Additionally, the terms now state that reconnection or restoration of service after suspension may incur a fee. These changes modify the conditions under which service can be interrupted and the predictability of pricing as services evolve.
