T-Mobile today kicked off a new program called Jump On Demand

T-Mobile today kicked off a new program called Jump On Demand, which will allow people to upgrade their phone for free up to three times per year. The Jump On Demand program builds on Uncarrier 2.0, which introduced the idea of early phone upgrades with Jump. Now customers can trade in their phone as many as three times per 12 months for a new handset at no additional cost as long as they continue to make the monthly phone payments. T-Mobile said customers can walk out of the store with no money out-of-pocket with Jump On Demand, though customers with poor credit may have to make a downpayment on their device.

The monthly pricing for Jump On Demand will be about the same as before -- the price of the phone divided by 24. Jump On Demand does not carry the extra $10 monthly fee that's part of the original Jump program. Phone trade-ins will have to be in good working order to be accepted for a new handset. T-Mobile said only a few flagship devices are eligible for the program: Apple iPhone 6 and 6 Plus, LG G4, and Samsung Galaxy S6, S6 Edge, and Note 4.oppo mobile Customers already enrolled in the Jump program can transition to Jump On Demand the next time they upgrade (as long as the balance of their current phone is paid off) and will no longer have to pay the $10 fee. Customers who join Jump On Demand and make 18 payments on their phone without upgrading will have the option of making one final payment to own the device or trade the device in. Customers can choose to pay the balance of their handset at any time. As part of the launch, T-Mobile is offering the 16GB iPhone 6 for $15 per month with Jump On Demand as long as an old phone is traded in at the same time. Jump On Demand will be available in T-Mobile stores beginning June 28.
