我也觉得T家的deal很划算啊。前提是2念你不换号... 举个例子.. 你有一个6，拿去trade in，我的理解就是把六换了2年的话费.. which is 27*24。 在普通市场里，6应该没办法换那么多钱吧？ 说不识数的mm还请赐教啊……

iPhone 7 Trade-Up Offer Created by tmo_marty on Sep 1, 2016 2:09 PM. Last modified by tmo_marty on Sep 9, 2016 12:19 AM. Starting September 9, 2016, and for a limited time, if you purchase the iPhone 7, the net cost of your new phone could be as low as FREE after 24-month finance agreement! And, if you purchase an iPhone 7 Plus, your net cost could be as low as $120. For Costco customers, this limited-time offer is available starting September 16, 2016. How the offer works The trade-up offer is available to new and existing T-Mobile postpaid customers, including T-Mobile employees and @Work customers. To take advantage of this offer: Purchase the iPhone 7: First, you need to purchase the iPhone 7 (32 GB) or iPhone 7 Plus (32 GB) during the offer period using our Equipment Installment Plan (EIP). If you want a phone with more memory, 128 GB and 256 GB versions of both the iPhone 7 and iPhone 7 Plus are available for an additional cost. Tax on the full sale price of your new device will be due at sale. Trade in your old iPhone: Next, you need to trade in your fully paid-off iPhone (from any carrier). For your trade-in to be eligible for this promotion, you must own the device outright, which means you can't have a remaining JUMP! On Demand or EIP balance. Also, the trade-in device must be in good working order without physical or liquid damage and have the “Find My Phone” feature turned off. Note: This offer cannot be combined with other offers or programs where a trade-in is required (e.g., Carrier Freedom). And, if you cancel wireless service before the end of your EIP agreement, the remaining device balance at full price will be due. What do I need to do? The steps you follow to take advantage of this trade-up offer depends on if you're new to T-Mobile or if you're already a T-Mobile customer. First time with T-Mobile? Once you receive your iPhone 7, go to [url=http://www.t-mobile.com/cell-phone-trade-in.html.]http://www.t-mobile.com/cell-phone-trade-in.html.[/url] Enter the following information: The order number for your new device. Your NEW T-Mobile phone number. Make sure you enter the new number that T-Mobile provides you with at the time of shipping, even if you plan to port in, or transfer, your current number to your new iPhone 7. Complete the trade-in steps. Ship out your old iPhone device. Already a T-Mobile customer? Go to [url=http://www.t-mobile.com/cell-phone-trade-in.html.]http://www.t-mobile.com/cell-phone-trade-in.html.[/url] Enter the following information: The order number for your new device. Your T-Mobile phone number. Complete the trade-in steps. Once you receive your iPhone 7, ship out your old iPhone device. Getting your rebates or bill credits T-Mobile will give you the value of your trade-in as a one-time bill credit. After that, we'll apply monthly bill credits toward your device monthly payments. Depending on the total of the trade-in value of your device and the monthly offer credits, your new device net cost could be as low as free after 24-month finance agreement. If you trade in your old iPhone at a T-Mobile retail location, you can use the value of the trade-in to buy down the EIP balance instead of getting the one-time bill credit. Costco members If you're a Costco customer, you can submit your rebate information by going to [url=https://promotions.t-mobile.com]https://promotions.t-mobile.com[/url] and using the Promotion Code 16SeptiPhone7. You must complete the trade-in process and submit your rebate request within 30 days of purchase and remain active and in good standing with T-Mobile when rebate is processed. After you complete the process, you should receive your rebate of the trade-in value in the form of a Prepaid MasterCard® card within eight weeks.
