Hard credit inquiries can temporarily lower your credit score and remain on your credit report for up to two years; consumers should be aware that simply applying for a service plan triggers this.
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.
