I would get the make clear lines in the sand...we had limits in AK and boy when you went over, it cost you like crazy...
we did NO movies, videos, you tube, etc....strictly internet bs only!
if schooling comes first then the rest will fall by the way side....or get them laptops and send them to the nearest McDonalds that has free WI-FI
PS. I have suddenlink and we are now paying $55 month!
