Where T-Mobile does well

  • Real 30-day arbitration opt-out per line (phone or online, publicized); no annual service contracts — porting your number auto-cancels; only big-three carrier extending CCPA rights to all US customers; 'Do Not Sell' honored; price-lock guarantee still exists for current qualifying plans.

No court, no class action — one person at a time before an arbitrator.

The fine print

6 clauses and findings from the draft archive, dated 1 October 2026. The plain English comes first; the small print is the company's own words. None of these has been checked yet.

  1. No court, no class action — one person at a time before an arbitrator.

    requiring individual mandatory binding arbitration of disputes, instead of class actions or jury trials.

  2. Miss the 60-day window and you lose the right to contest the charge anywhere.

    you must notify us in writing of any dispute regarding your bill or Charges to your account within 60 days after the date you first receive the disputed bill or Charge. If you don't, you may not pursue a claim in arbitration or in court.

    Same T&Cs

  3. They can change the deal unilaterally; using your phone = acceptance.

    we may change, limit, suspend or terminate your Service or this Agreement at any time… If the change to your Service or Rate Plan will have a material adverse effect on you, we will provide 14 days' notice of the change. You'll agree to any change by using your Service after the effectiveness of the change.

    Same T&Cs

  4. Your behavior data gets bundled and sold.

    Aggregate reports may be used by T-Mobile or sold to other companies.

  5. FCC found T-Mobile sold customers' real-time location data without consent — the biggest carrier fine.

    T-Mobile willfully and repeatedly violated section 222 of the Act… by disclosing its customers' location information, without their consent, to a third party who was not authorized to receive it — forfeiture of $80,080,000.

  6. No service contract, but cancel and the entire remaining phone balance comes due immediately.

    cancellation of Service may affect other agreements that you have with us, including equipment installment plans or lease agreements where some of your payments may be accelerated upon cancellation.

    Same T&Cs

How these were found

Live T&Cs page (effective Sept 1, 2026) fetched but accordion sections are JS-rendered — full clause text cross-checked against July 3, 2025 court-filed copy (Case 1:25-cv-00686-BBC, Document 10-3) via archive.org plus current search snippets; wording consistent. Privacy Notice read live (June 26, 2026). Price-hike history and T-Mobile's Oct 2024 arbitration-based block of the price suit are from press/coverage, not T-Mobile's own docs.
