The updated terms remove prior language stating that if a promotional rate plan customer qualifies for a price-related promotion, T-Mobile will not increase monthly recurring charges except per promotion terms. The revised language now states that price commitments do not extend to new technologies, features, or services unless expressly stated otherwise. This means promotional customers may face price increases for new services or technologies not explicitly covered by their original promotion. Additionally, T-Mobile expanded grounds for service termination to include theft and unlawful conduct, and restructured how account authorization and credentials are managed, requiring authentication of Authorized Users before access is granted.

When you make a booking, you agree to pay the cost of the Travel Experience, including any charges and taxes that may apply.
We may collect partial payments for unpaid amounts from any Linked Account, but any partial payment is not a waiver of our rights and will not satisfy your obligation to pay in full.
You're responsible for all applicable taxes, and we'll charge tax when required.
