T-Mobile is known for offering Valentine’s Day deals every year, and this year is no different.

Starting tomorrow, February 10, customers who add a line can get a second line of free service. The line will be covered by a monthly bill credit that’s applied to the lowest cost line added while the offer is available. If you cancel any of the paid lines, the credits will stop.

In order to get this deal, you’ll need to be on a T-Mobile One family plan with at least two voice lines. Also of note is that there’s a limit of one free line per account with this offer.

This free line deal is stackable with other T-Mobile offers. That means that you can combine it with T-Mobile’s Buy One, Get One deal on flagship smartphones from Apple, Samsung, and LG.

Also kicking off on February 10 is an Apple Watch discount. Customers who buy an Apple Watch Series 3 can get a second for half off. This deal is also stackable with T-Mo’s offer of a free line of service.

Rounding out the Valentine’s Day deals is a discount on Beats headphones. Right now you can get $60 off the Beats Solo3 ($239.99), $40 off the Powerbeats3 ($159.99), and $30 off the BeatsX ($119.99).

Will you be taking advantage of any of T-Mobile’s Valentine’s Day offers?
