Sprint's program is called One Up, and lets customers upgrade their device once every 12 months. The One Up plan costs $65 per month and includes unlimited talk, text and data for the life of the line. Customers will then have to add in the cost of their device, which will be broken down into 24 equal payments and added to the monthly bill.
Existing customers who are eligible for upgrades can take advantage of the new program, which goes into effect today for new contracts.
