Magenta Friday has arrived.

T-Mobile is now offering its Magenta Friday deal that’ll get you two lines for free. The offer is available wherever T-Mobile new lines of service are available, including T-Mo stores, Costco, customer care, telesales, authorized postpaid dealers, and T-Mobile’s website.

With this offer, new customers signing up for two voice lines on a Simple Choice or T-Mobile One plan can get two additional lines for free after monthly bill credits. The first two lines must be voice lines, but after that, you can get voice, mobile internet, or wearable lines for free.

Existing Simple Choice and T-Mobile One customers are also eligible for this promo. Keep in mind, though, that if you’ve already got one line free because of a previous promotion, you can only get one extra line free. There’s a max of two free lines per account.

Finally, these free lines are good for as long as you maintain qualifying service and stay on your current plan. If you cancel service on any lines or switch to a non-qualifying plan, you’ll lose your monthly bill credits.

T-Mobile will offer fourth line free deals every now and then, but this two lines for free promo is a bit more special. The deal will only be available from today until Sunday, November 20, so keep that in mind if you’re thinking about taking advantage of it.
