T-Mobile Family Cell Phone Plans

The T-Mobile One family plan is an attractive option if you, your partner or your kids burn through data. There are other, less expensive unlimited plans out there, but T-Mobile’s plan also allows unlimited mobile hot spot use. However, if you’re outside a major metropolitan area, T-Mobile’s network might leave something to be desired.

How T-Mobile’s family plan compares on prices

T-Mobile One’s advertised price now includes most monthly taxes and fees, the kind that might otherwise inflate your bill beyond what you expect. It doesn’t include taxes or fees for add-ons like insurance or phone payments.
