If you’re unaware, T-Mobile offers a monthly payment plan that it calls its “value plan program.” Here’s how it works: typically, you can purchase a phone with a down payment and then pay off the rest of the price of the device over the length of your contract. It works similarly to how a subsidy does, but you pay more when you buy the phone. The carrier is currently offering a value plan deal, however, that will offset the price of the down payment.

The “$0 down sale” will apparently run until the end of the year and includes high-end devices such as the Galaxy S III, the Nexus 4, the Galaxy Note II and the Windows Phone 8X. Those devices will cost you $199.99, $149.99, $299.99 and $149.99, respectively and each includes a mail-in rebate that ranges from $150 to $200. Other phones and tablets currently on sale include the Galaxy S Relay 4G, the HTC One S, the BlackBerry Bold 9900 and the Galaxy Tab 2 10.1.

The catch is, the actual “down payment” only hits $0 after you receive your mail-in rebate. In other words, you’ll be able to get the Galaxy S III for $199.99 with a $0 down payment after you receive the $200 mail-in rebate. So, technically, you’ll need to pay the cost up front. Still, it’s a solid deal if you’re looking to pick up a new phone on T-Mobile’s value plans before the year ends.
