T-Mobile is sweetening its ONE plan this Valentine’s by offering a free line of service when you add a new one to an existing family plan or start a new one. That may sound slightly confusing, but what it really boils down to is that you can get a T-Mobile ONE plan with 4 lines for $35 per line (that’s $140 total), instead of the usual $40. T-Mobile’s ONE plan already comes with unlimited 4G data (throttled at >50 GB), tethering, data roaming in 140+ countries, and a standard Netflix subscription.

The catch seems to be that, if you already have a family plan, you have to add a new line to get the second one free. In other words, if you’re already on a family plan with 4 lines, you probably won’t be able to get 4 lines for the price of 3, but you will be able to get 6 for the price of 5. Still, that’s a pretty good deal for new customers or if you were already considering expanding your current family plan from 2 to 4 lines.

T-Mobile says this is a “limited-time offer,” but it doesn’t specify when it’ll expire, so if you’d like to take advantage of the promotion, you should probably do so sooner rather than later.

Edit: A reader says that a representative confirmed the deal expires on the 15th.

Bellevue, Washington — February 9, 2018 — BAD line: “Are you a parking ticket? Because you’ve got FINE written all over you.” GOOD line: the one you get for FREE at T-Mobile, just in time for Valentine’s Day!

“Flowers and chocolate are for amateurs,” said John Legere, president and CEO at T-Mobile. “Step AWAY from those stuffed bears and candy hearts, and get your valentines something they’ll actually use and love!”

Even better, you can combine your free line deal with all of the Un-carrier’s current offers, including BOGOs on twelve superphones from Samsung, LG and others.
