How to ensure Binge ON is Activated for Simple Choice MI 6gb Line?

I have an old free Simple Choice MI 6gb line running on a Franklin T9. Unforttunately, MI SC lines were not upgraded to unlimited like other data limited SC voice lines. I remember this line having Binge On, but there seems to be little documentation in the app or online indicating whether it's on or not, how to activate it, and what is covered (youtubetv?) Anyone have any insights?
