T-Mobile

T-Mobile's Terms & Conditions are very long (a count of 71 pages / 20,116 words has been cited but was not verified in this review), and plaintiffs in Panchal v. T-Mobile (M.D. Fla. 2024) argued the arbitration clause was unconscionable — but the court rejected that argument and compelled arbitration, so the clause has held up in court. That same clause is ALSO broader than most competitors': it explicitly covers PRIVACY AND DATA-SECURITY disputes, not just billing fights, meaning a customer would have to read a very long document to discover they've waived their right to sue over a data breach.

Arbitration

Mandatory individual binding arbitration explicitly covers privacy/data-security disputes, not just billing — broader scope than some peers. In Panchal v. T-Mobile US, Inc. (M.D. Fla. 2024), plaintiffs challenging T-Mobile's data practices argued the arbitration agreement was unconscionable; the court found it neither procedurally nor substantively unconscionable, pointed to a clear opt-out provision, and compelled arbitration. (A T&C length of 71 pages/20,116 words has been cited but was not verified.) T-Mobile does offer a documented opt-out process (30 days from activation).

Legal notice. PUBLIC COMPANY (TMUS). Service route: c/o General Counsel / Corporate Secretary, Bellevue, Washington — the corporate address on the SEC Form 10-K cover page is the official address of record. Confirm the exact street address on the current 10-K at sec.gov/edgar, and check the state-of-incorporation registered agent (usually Delaware; most large filers use The Corporation Trust Company or Corporation Service Company) via the Secretary of State business-entity search. A registered agent MUST accept service, which is why it is the reliable channel when a company publishes no privacy address.
