T-Mobile brings back its two best iPhone deals of the year for four days only; sales begin tomorrow
The conditions of the deal/s may have changed since the initial publishing of this post.
T-Mobile is bringing back its deal that saves you $300 on the iPhone X with the trade-in of a qualifying iPhone
The second deal making an encore is one that will chop $300 off the price of your Apple iPhone X. Simply trade in a qualifying older iPhone model, purchase your tenth anniversary edition using an Equipment Installment Plan (EIP), and you'll receive the rebate in the form of 24 monthly bill credits of $12.50 each. Keep in mind that T-Mobile's business customers are eligible for both deals.
You've already let these two deals slip right past you without taking advantage of either one of them. Now, T-Mobile is giving you a second chance to get a new iPhone on sale. Miss this opportunity, and there is no guarantee that you will get a third shot at saving money on the iPhone you've been dying for. Remember, you only have until the end of the day Sunday to take advantage of either deal.
