New and existing Sprint customers who add a new line of service and trade in an eligible device can get an iPhone X for $5 a month with Sprint Flex lease. The promotion is only available for one week at Sprint stores, or by calling 1-800-SPRINT-1.

“Sprint continues to offer the best limited-time promotions like iPhone X for $5 a month, a deal you can’t get anywhere else,” says Dow Draper, Sprint chief commercial officer, in a press release. “Offers like this encourage consumers to try Sprint and experience our improved network, and the immersive all-screen display of iPhone X makes it a perfect fit for streaming content.”
