none of the new iPhones play nice with T-Mobile’s 600MHz network, so they’re not devices you want to rely on for years to come. But unless you live in Wyoming or Maine, you won’t see the benefits of 600MHz for the next year.
T-Mobile’s second promotion doesn’t take place for another year, but it’s a big deal. If you buy an iPhone 8 on an Equipment Installment Plan right now, you’ll be able to upgrade to next year’s iPhone for free when it comes out. T-Mobile will offer free upgrades to the 2018 iPhone when you trade-in an iPhone 8, 8 Plus, or X that is over 50% paid off.
