when I see "ör a majority of kilobytes", this (to me) indicates that if you are a heavier data user, they may be more forgiving with or a have a soft limit. If you consistently used 3GB+/month on network, I would venture to guess that as long as you are in the ballpark of 10% or less of total data used off-network they wouldn't suspend you.
Anyone have a good source on this or from Sprint internals? I was quoted this when I began service in 1998 (no more than 10% usage off nework). Of course terms and conditions change over the years, but the present (see below) doesn't seem completely ironclad.
"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.
