Welcome, munchiez117! Thanks for posting. We can't review accounts as members or Managers of the Support Community, since it's a public user forum, but from your description it sounds like the charge you're seeing is for an additional line on a T-Mobile ONE Taxes & Fees Included family plan. Since a family plan starts at two lines, any additional line -- three, four, five, etc. -- has a separate fee associated with it.
