Customer Proprietary Network Information (CPNI) Use and Disclosure

High severity
Share 𝕏 Share in Share

What it is

T-Mobile collects your call records, data usage patterns, and network activity as CPNI — information protected under federal telecommunications law — and may use and share it subject to specific legal requirements and your consent rights.

Why it matters

CPNI includes sensitive details about who you call, when, and for how long, and is federally protected; consumers have rights to restrict its use for marketing and to be notified of unauthorized disclosures.

Institutional analysis (Compliance & legal intelligence)

CPNI obligations arise under 47 U.S.C. § 222 and FCC regulations (47 C.F.R. Part 64); compliance teams should verify that T-Mobile's CPNI opt-out mechanisms, annual certification, and breach notification procedures meet current FCC requirements including the 2023 updated data breach rules.

Consumer impact

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. You can opt out of T-Mobile's Advertising & Analytics program and request deletion of your personal data by visiting https://www.t-mobile.com/privacy-center.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.
  • Opt Out of Arbitration
    Call T-Mobile customer service at 1-800-937-8997 and request to restrict the use of your CPNI for marketing purposes. You may also be able to manage this through your online account settings.
