Sprint Zone is a free app for smartphones that allows Sprint users to view a detailed overview of their cellular usage data and pay bills directly from their device. With usage statistics from their current billing period, users can breakdown their personal activity and usage of other devices on the same plan. Users can also pay bills in-app and never have to worry about missing a payment again. With access to comprehensive usage details, the ability to make appointments at a Sprint store and manage your lease, Sprint Zone covers all the basics of account management.
