T-Mobile’s got a new deal, but it’s only be available this weekend.

Starting this Friday, you can get a free Samsung Galaxy S7 when you buy one on an Equipment Installment Plan. The second Galaxy S7 will be free with 24 monthly bill credits. If you cancel service before those 24 months are up, the remaining balance on the phone will be owed.

Also worth noting is that the second Galaxy S7 must be activated on a qualifying line of service. I reached out to T-Mobile to clarify what the qualifying lines of service were, and here’s how it breaks down:

• Existing customers [with Simple Choice Unlimited plan]: Simple Choice Unlimited or T-Mobile ONE line is required with the second device to be eligible.
• Existing customers [with plan other than Simple Choice Unlimited or T-Mobile ONE]: T-Mobile ONE plan required with first device and second device to be eligible.
• New customers: Required to port-in a line and activate both devices with T-Mobile ONE service to be eligible.

The Galaxy S6, Galaxy S6 edge, and Galaxy S6 edge+ are also eligible for this offer if you’d prefer one of those devices instead of the Galaxy S7.

This deal will be available starting at 6:00 am PT on Friday, November 11, and it’ll run through 11:59 pm PT on Sunday, November 13. It’ll be offered at T-Mobile stores, online, and through telesales.

The Galaxy S7 may not be the newest Android phone on the block, but it’s still one of the better Android phones available. Its spec list includes a 5.1-inch 2560×1440 AMOLED display, Snapdragon 820 processor, 4GB of RAM, 12-megapixel camera, and a microSD slot. Also of note is that the GS7 will be updated to Android 7.0 Nougat.
