If you do not want to trade in your current iPhone, T-Mobile has a JUMP! On Demand promotion that offers the 16GB iPhone 6s for $20 per month for 18 months with zero dollars paid upfront, totaling $360 under the agreement the device is returned in good condition. To keep the iPhone, you must pay an additional $164, bringing the total cost to $524 -- a savings of $125 and the best deal for those willing to join T-Mobile.
6/ YES – you read it right! Trade-in an iPhone6 & get a new #iPhone6s for $5/mth or trade-in your iPhone5s & get a new one for $10/mth!— John Legere (@JohnLegere) September 22, 2015
T-Mobile will honor this deal for customers who already pre-ordered an iPhone 6s or 6s Plus.
