If T-Mobile's service failure causes you significant financial harm — such as a missed business deal due to an outage — you cannot recover those consequential losses, only the direct amount you paid for the service itself.
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.
