T-Mobile is not required to notify you of any changes to the terms that are not materially adverse, i.e. do not change your pricing or the service that you actually receive. Changes like this are normally just clarification, restructuring of the T&C's, etc. Any materially adverse changes must be disclosed to you, per the policy listed in the T&C's.
