we are getting ready to go fulltiming at the end of Dec. While I don't have direct experience with multiple companies. All the research I've done and people I've talk to that had it, says/said Millenicom hotspot service is the best. We got it and are using it at home while we still have the cable internet back up. It's been working well so far a few hiccups just recently we had to call there tech support and uncheck something because a lot of websites wouldn't come up.
The problem I hear with the Sat services is the low data amount they give you which you can burn through pretty quick then the problems/expenses start to pile up.
