data plan

I never use campground wifi systems, mainly because they're slow. I've got AT&T share plan with 30g data. They do roll over unused data to the next month but it is not cumulative. Most months I have 40 or so gig to play with. IF you see that you are going over you can go on line and up your plan temporarily. A way to save a little money is to get rid of your home internet to offset the costs of the mobile data. My 4G lte is as fast or faster than my uverse internet. I stream netflix etc with no problems, even in the boons, where I have coverage. I rarely find a place where there is no AT&T coverage.
