I went with MIFI 2200 several years back working on 2G 3G platform and had it sitting in a WILSON SLEEK Cradel with a small external antenna... Being on the VERIZON CELL PHONE service really did great when I was off the Interstate roads and away from the large towns...

I had this cradle mounted up on the inside of my POPUP trailer near the roof behind the wrap around curtains... Was out of sight and provided excellent service for my needs for my 90% off-road camping...
This gave me a good 50-60 feet around my popup trailer using my other devices on the internet...
Of course the 2G SERVICE is not the way to go these days and I have long removed this setup from service...
I just recently got a new MIFI 6620L JETPACK unit through my VERIZON Cell Phone account and it works great taking on a few trips... This one has up to 4GB I think it is... Will most likely do the same thing for my trailer and get another WILSON CRADEL to match the new MIFI6620L...
I never had a lot of luck with WIFI signals at camp grounds etc... Having your own 'secured' HOT SPOT is the way to go for sure... The newer smart phones gives this as well but my old GIBBS flip cell phone doesn't support that haha...
