For surfing the internet a cellular hot-spot is better than the Sat services due to speed. I've been able to get cellular services in most all of the places we've camped - I use Verizon network, a Verizon MiFi hotspot, and - when needed - a cellular antenna on top of a 35' pole strapped to the back of the RV (only when camping, of course). This almost always delivers a signal. I've been skunked in the deep woods of Northern Minnesota up by Zipple Bay (that little "hat" on the top of a Minnesota Map buy the Lake of the Woods).
Oh, that is another thing, I think the Satellite technique requires a clear line-of-site to the appropriate satellite. I'm not sure you can always see that depending upon your latitude, tree cover, hills/mountains, etc.
Recommend: a MiFi (make sure it has a plug-in for an external antenna) on a network with wide coverage (ie, Verizon).
