You may find that terms you originally agreed to have been changed without your affirmative consent, and simply continuing to use your phone constitutes acceptance of potentially less favorable terms.
Consumer impact
T-Mobile's terms significantly limit how consumers can resolve disputes β 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.
