I have been looking around at Satellite Phones and services, and these guys seem to be the cheapest and the best.
http://www.globalstar.com/the only other service I might consider is phone rental.
http://www.satellitephonestore.com/satellite-phone-rental.phpBut in terms of Satellite Phones your still only getting 56-64KBPS for the smaller/cheaper models, and 128KBPS-492 kbps for the bigger high end/suitcase models.
Which is strange cause most comminications sent through cell phone across continents is routed through Satellites anyway.
You would think that it would be much faster, but the technology hasnt seemed to evolve much in the past 5-10 years.
