One thing users can do with a used Sprint phone, as of 2015, is to trade it in and receive instant credit toward a new phone purchase or an account credit, as long as the device is eligible. Used Sprint phones ineligible for a trade-in can be recycled using Sprint's Project Connect, which helps fund Internet safety resources for kids.
At SprintBuyBack.com, click the Eligible Devices tab to see an alphabetical list of phones eligible for a credit with the Sprint Buyback Program. Click the Home tab, and then click the Get a Buyback Quote button to enter the device information. If accepted, Sprint will pay for the postage with a prepaid shipping label. Once Sprint receives a used phone, it is processed and credited to the user's account within three billing cycles.
To recycle a phone with Sprint, use the free postage-paid recycling envelope that came in the box with the phone when it was purchased. Alternatively, users can print a free, prepaid shipping label online at SprintBuyBack.com. On the home page, click the Recycle Now button, and fill out the form to print the label. Sprint sells the recycled phone and uses the proceeds to help fund Internet safety resources for organizations such as the Boys & Girls Clubs of America and the National Center for Missing & Exploited Children.
Before trading in or recycling a used phone, Sprint recommends removing or transferring any personal information that is on it.
