Frequently asked questions

The Billing Responsible Party is the person who’s responsible for the account. Usually this is the person who opened the account with T-Mobile and signed the service agreement. An account can only have one BRP, and they must be at least 18 years old (at least 21 in Puerto Rico).

That person will be listed as the Billing Name on the account. They’re responsible for all costs associated with the account and for all lines on the account. They’re also the only person who can make account changes.

The Primary Account Holder is often the same as the Billing Responsible Party, but not always. The Primary Account Holder is named by the Billing Responsible Party when the customer sets up a T-Mobile account either in the app or at my.t-mobile.com. 

The Primary Account Holder sets access and permissions for other lines, can view account activity, and has full access to account management options.
