Here's the legal description:

Off-network Roaming: The primary use of your Device must be for domestic purposes within the Sprint-owned network. Domestic means use in the 50 United States and U.S. Territories (except Guam). Sprint reserves the right, without notice, to deny, terminate, modify, disconnect or suspend service if off-network usage in a month exceeds: (1) voice: 800 min. or a majority of minutes; or (2) data: 300 megabytes or a majority of kilobytes. The display on your device may not always be on and will not indicate whether you will incur roaming charges. You can monitor usage online through My Account. Roaming is not available with single-band phones, or to customers who reside or whose primary use is outside an area covered by the Nationwide Sprint Network. Sprint may limit or terminate service if you move outside of the Sprint owned-network.
