"With Jump! On Demand, you make payments on your phone for 18 months. After 18 months, you can simply turn in your phone with nothing more to pay, or upgrade to your next new phone and start a new plan, or make a final payment and keep your phone. If you keep your phone and make the final payment, the total of your payments will equal the retail price of the phone. In addition, customers can pay off their JUMP! On Demand plan at any time by paying the remaining payments in advance, and keep their phone without penalty."Customers that cancel their T-Mobile wireless service in less than 18 months must pay the sum of their final monthly payments and return the working smartphone, or purchase the smartphone outright for a fee, such as $164 for the iPhone 6. Jump on Demand will be available for eligible devices at participating T-Mobile stores in the United States beginning Sunday, June 28.
T-Mobile is offering the iPhone 6 and iPhone 6 Plus through Jump On Demand for just $15 and $19 per month respectively for a limited time, prices that are unmatched by competing carriers. T-Mobile customers interested in the deal can sign up to receive updates about Jump On Demand through the carrier's website.
