T-Mobile is hosting a weekend-only deal for the Samsung Galaxy S7, which could get a customer two of this year’s flagship phones for the price of one.

The Un-carrier has confirmed the event starts at 9:00 AM PT on Friday, November 11, and will run until 11:59 PM PT on Sunday, November 13. The promotion is a buy one, get one deal for the Samsung Galaxy S7 (the Galaxy S6, Galaxy S6 edge, and Galaxy S6 edge+ are also included). Customers can take advantage of the deal either through their local retail store, over the phone, or online.

To get the deal, you’ll need to buy a qualifying phone and sign up for an installment plan. For the Galaxy S7, that means $0 down and 24 monthly payments of $28.75. You then need to buy another phone and put it on a qualifying line of service, which will then receive monthly bill credits in the total of the installment plan’s monthly charge.

“This weekend only at T-Mobile, when customers buy a Samsung Galaxy S7 with T-Mobile’s Equipment Installment Plan (EIP), they’ll get another one free after 24 monthly credits when they add a qualifying line of service.

Not a T-Mobile customer? Not a problem – anyone can easily make the switch to the Un-carrier and get the same deal. And, with Carrier Freedom, T-Mobile will even pay off remaining device payments and early termination fees with your old carrier – up to $650 per line or more via trade-in credit and prepaid Mastercard® Card.”

If you cancel the service before the 24 months is up, on either device, the remaining balance on the device will be due, as is par for the course with installment plans.
