If you’ve got an unlimited data family plan at T-Mobile, you’ll soon be getting free Netflix to go along with it. The new “Netflix on Us” perk is T-Mobile’s latest attempt to differentiate its service from that of larger rivals Verizon Wireless and AT&T. There’s not much fine print here; as long as you’ve got two or more lines on a T-Mobile One unlimited plan, you’ll eligible to receive a standard Netflix subscription at no extra cost. The deal will launch starting September 12th and can be activate online, in-store, or by calling customer service.

T-Mobile says that customers who took advantage of the company’s “line-on-us” promotions still qualify for free Netflix. But it sounds like that’s not necessarily true for people on the 2-lines-for-$100 or recently announced Unlimited 55+ plans. Those subscribers can get the Netflix offer “by switching to the latest T-Mobile One plan.”
