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.
T-Mobile collects detailed network usage data about customers and may use it for marketing or share it with affiliates; consumers have a regulatory right under FCC rules to restrict certain uses of this data by contacting T-Mobile.
