We use the VERIZON MIFI account here and it provides us secured WIFI for five of our WIFI enabled devices. I have a grandfathered 3GB data plan for just $27 a month and this is perfect for what we are using it for. Just to check-in with the kids, pay a few bills on-line, answer some emails, and do a minimum surfing on the internet... Have never gone over my 3GB dataplan...
I use the WILSON SLEEK cradle for the docking station for the VERIZON MIFI unit which connects to an outside antenna on my trailer or pickup truck.
Works great anywhere we pick up VERIZON Cell Phone service.
Also small enough to slip in your shirt pocket and carry your tablet along with you doing some beach chair setting...
Even works pretty good running the TABLETS going down the road...
Must be good as neighbor campers are always coming over asking if the strong WIFI signal is us haha...
Its up to you to have a good PLAN B...
