Bill.satellite summed up the current situation with sat internet pretty well. I have a Motosat F1 internet dish on top of our motorhome that aims at the satellite automatically, most of the time. It does work anywhere. But the speed is slow. I tried to increase the speed about two months ago and they said I could not, so I did not renew the service. The speed is normally more than 1/10th as fast as 3G, but it is usually slower than 3G. All the internet services speed is dependent on how many users on it. If they wanted to Huges could give lightening fast sat internet, but they don't want to at this time. So could Via Sat, which is another high speed provider. We could get very high speed sat internet at our house, but not at our motorhome.
If you absolutely have to have internet connection get a satellite internet dish. If your need is less than that get a good smart phone with a hot spot feature. I personally use Verizon which has good coverage. Not everywhere though.
