The issue that may arise is that by you using that much data,Sprint can figure out that you are tethering and that if you are not paying for Phone as Modem they may consider that a violation. Even if there is no cap on cellular data use but I think the 5gb cap applies to cellular data use as well as the air card. There may be an exception regarding the Unlimited Simply Everything Plan but that has been discussed in other threads. Sprint has been known to send letters out regarding notification of the 5gb data cap overage use. Don't want to be greedy
