Hey, welcome to EQ! I would call sprint first thing tomorrow morning or log onto your online account and see if you have been charged for the data usage. I believe everyone can get data, you have to ask specifically to have it turned off. Most likely you have been charged for your usage, but talk to Sprint about it and see what kind of deals you can work out with them. If you don't want the service then tell Sprint that and have them put a block on your account for data. They should do so. If not, spend the $15 extra a month and get unlimited data. I didn't think I would ever use it as much as I do. Being in college too I use it for research and such when there is no wifi available. Hope this helps.
