How to Get a Free Phone From Sprint if You Already Have a Plan

1. Visit Sprint's New for You Upgrade Program Web page to determine if you are eligible for a new free phone. Enter your phone number and billing zip code into the upgrade eligibility checker.
2. Select a phone that costs less than the credit you will receive for renewing your contract.As of December 2010, you receive credit of $25, $75 or $150 toward the cost of a new phone, depending on the length of your renewed service contract and the amount of time since you last received a discount.
3. Maintain your renewed Sprint contract for the duration of the agreement.
