This weekend only, T-Mobile customers will have the chance to get a 32 GB Samsung Galaxy S6 for $0 down and $0 per month for 18 months with an eligible trade in.

The deal applies to those who trade in an iPhone 6, iPhone 6s, Samsung Galaxy S5 or Samsung Note 4, Note 5 or Note edge on the carrier’s JUMP! On Demand payment and upgrade plan. Users who trade in an iPhone 5, iPhone 5s, Samsung Galaxy S4, HTC One M8 or LG G3 or G4 will be able to secure a new Galaxy S6 for $15 per month.

Those with no trade-in device will face a monthly payment of $24 for the S6.

Customers who take advantage of the deal will be able to keep the promotional price rate for the duration of their JUMP! On Demand agreement for as long as they use the phone on T-Mobile. Those who cancel T-Mobile service will have to either pay off or return the device.

After this weekend, however, monthly plan pricing for the S6 will jump to $10 per month for those who haven’t already signed up.

T-Mobile is also sweetening the pot by offering customers who buy and activate an eligible Samsung smartphone – including the S6 mentioned above – a free Samsung Galaxy Tab A 8.0 tablet for no money down and no monthly payments when they add a data plan.
