CPNI Data Rights and Sharing

Medium severity
Share 𝕏 Share in Share

Why it matters

CPNI contains sensitive information about your calling patterns, location data tied to network usage, and service details. How this data is used and shared affects your privacy and can be used for targeted marketing or shared with affiliates.

Consumer impact

T-Mobile's terms significantly limit how consumers can resolve disputes — mandatory arbitration and a class action waiver mean most legal claims must be handled individually outside of court. T-Mobile also reserves broad rights to change rates, suspend service, and share certain customer data. You can opt out of the mandatory arbitration clause by sending written notice to T-Mobile within 30 days of activating service.

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 and request to restrict the use of your CPNI data for marketing purposes. Ask the representative to note your restriction request on your account and request written confirmation.
