Save up to $300 when you buy the iPhone X and trade in your old iPhone at T-Mobile

T-Mobile revealed last month its $300 off iPhone launch promotion, but if you missed it, here are a couple of details that will help you choose the best deal on the upcoming iPhone X.

First off, you'll be able to pre-order the iPhone X from T-Mobile beginning 12:01 a.m. PT Friday, October 27th online and at participating stores the following morning. Keep in mind that the iPhone X will be available in stores starting on November 3, but there won't be too many units available.

The iPhone X will be available for purchase at T-Mobile for $279.99 down and $30 monthly payments for 24 months. The 256GB model can be had for $429.99 down and $30 monthly payments for two years. These prices are available for customers who opt for the Equipment Installment plan.

However, those qualifying for JUMP! On Demand will be able to get the iPhone X for $0 down and $41.56 monthly payments for 24 months. The 256GB iPhone X will be available for $429.99 down and $24 per month for 24 months.

Also, starting Friday, customers who trade in their qualifying iPhone (iPhone 7, 7 Plus, 6, 6 Plus, 6s or 6s Plus) will get up to $300 off their new iPhone X via 24 monthly bill credits on T-Mobile’s interest-free installment plan.

But there's more, as T-Mobile announced that iPhone X customers will be added to its new iPhone upgrade program, which will allow them to upgrade to a new iPhone when 50% of their current model is paid off.

T-Mobile will wipe out the remaining payments so you'll be able to upgrade to that next iPhone free and clear. It's worth mentioning that customers who buy the iPhone X on T-Mobile’s installment plan automatically get this one-time benefit for free.
