Verizon Mi-Fi 4G. You can connect several devices, like Kindle, laptop, etc. We have used it all over the US with zero problems. 2 places we had to use a booster. We have Wilson Sleek for that. When I'm at a campground that has fast wi-fi, I use theirs for email and non-secure type transactions. That is few and far between. Most campground wi-fi is slow if it even works at all. I always use my Verizon for banking, paying bills, etc. They have many different data plans. I think mine is $60 per month. If I go over, it's about another $10. No biggie.
