Corporate globalstar that now owns the gateways in north americam
central america, and parts of western europe has elimated all roaming
services. Apparently it does not fit there 'business model.' Most of
the indendent gateways such as elsacom(central & east europe), turkey,
russia, australia, etc. still offer roaming for gsm customers. You
could get a globalstar europe SIM to use in your phone. If you do this
you can get unlimted service throughout the coverage area; this even
includes free calls to premuim rate cell phone number, etc. the cost
is 35 euros per month. BUt there is a problem the globalstar
satellites are having serious communications problems as they have
gotten old. Expect to wait a significant amount of time for a
functioning satellite to fly overhead and than be cut off after a few
minutes. If the financing does not fall through it will be sometime in
2010 when service starts returning to normal. The satellites will be
launched over a period of years; so I would not expect uninterupted
service before 2014 or so. There are many of us who watch this
industry who do not expect to ever again see reliable globalstar
service. I costs about $1 billion dollars to launch satellites for a
company that earns about $25 million per year. You do the math.

If you need a reliable sat phone that has good tariffs look into
thuraya. the website is www.thuraya.com. they have a prepaid plan that
only cost $0.39 per minute for calls from europe to most of the world.
You can also roam onto thuraya from most gsm plans.
