Beginning September 12, T-Mobile will offer its customers a Netflix Standard 2-Screen Monthly Subscription for free when they sign up for two or more lines on a T-Mobile One wireless family plan. That's a savings of $10 per month. Customers can activate and link their existing Netflix service within their T-Mobile account. (T-Mobile will pay Netflix directly.)
