The VERIZON MIFI does that for us when camping... Gives me a monthly 3GB dataplan for $27.
I use my secure MIFI unit sitting in a WILSON SLEEK Cradle which has an outside antenna and this give us a good Verizon Internet signal connection. We have a 100 feet or so of hot spot coverage around our camp site and inside the trailer using up to five devices like computers and tablets on the internet etc... all at the same using the MIFI unit. With the WILSON SLEEK CRADLE in the truck we get great internet connections from VERIZON driving down the roads. Great for the tablets doing this...
This is great for paying bills, keeping in touch with the kids, and some surfing on the internet. The dataplan is not big enough to do any downstreaming of TV or Videos. You need a min of 20GB a months for that. I think those things eat up around 1GB an hour when being used...
I am always leary of logging into the various open WIFI places that show up on my units.
We never had much luck depending on the camp ground WIFI. It depends mostly on how full the camp ground is. It really gets bad when everyone gets on it in the evening...
