Turn in your current iPhone and get the iPhone 6s for as little as $5 a month from T-Mobile
If you'll trade in a working iPhone 6, you'll be able to get the iPhone 6s with 16GB of internal storage for just $5 per month. Those who trade in an iPhone 5s will be able to get the entry-level iPhone for 10$ per month. Trading in an older device is also possible, but T-Mobile will raise the monthly payments to $15. T-Mobile's CEO said that even those who've already pre-ordered the iPhone 6s can take advantage of this deal.
If you have your eyes set on an iPhone 6s with more internal storage or an iPhone 6s Plus, you'll have to pay more, although the exact details have yet to be revealed by the Magenta carrier. Since this is T-Mobile's Jump! On Demand program we're talking about, those who take advantage of this promotion will be able to upgrade to newer smartphones up to three times per year. Without trading in an older iPhone, customers can get the 16GB iPhone 6s for $27.08 per month.
More details about T-Mobile's iPhone trade-in extension for the Jump! On Demand program will be announced later today, so stay tuned if this seems like a good deal to you.
