An internet booster boosts an internet signal that someone provides to you, like a store or restaurant or coffee shop. Except you are not going to be able to find any loose internet signals while boondocking in the wilds, no matter what state you are in. What you are going to need is a contract with a cell service provider such as Verizon, which really does have the widest network. Then you will either use the data on your cell phone or use a couple of mobile hotspots. I mention a couple because at least in my case, I get 30 gig of data at 4 G with each one before Verizon throttles me down.
If you want to boost anything, you will need a cell phone signal booster to get a better signal while you are boondocking somewhere.
I am online 5-7 hours per day, so I have two mobile hotspots which I purchased from Verizon for $200 each. I pay $148 per month for "unlimited" data, which is really not unlimited because I get 30 gig of fast speed and then unlimited really slow speed. My contract also covers unlimited cell phone calls and 20 gigs of data on my cell phone if I need it.
You can always drive into town and find a mall or someplace like McDonalds or Starbucks that provides free internet and use an internet booster for that. I do have an internet booster that I used to use for that, but now use only occasionally when I am at a campground that provides free internet. However, be aware that for 95% of commercial campgrounds, free internet means you have to be sitting next to the activity center or directly under the wireless access point. IN other words, it is almost always useless.
You can check into satellite internet, however. Not sure what that provides or what it will cost you, but obviously you will need to buy a satellite dish and some other equipment. (Providers make you purchase a satellite for RVs, as opposed to with home use where they bring you a satellite and let you rent it.)
