don't worry, use mine in deep mtn valleys all the time. Tou may have to waite 5 minutes or so for signal to optimize. don't forget these sats are moving all the time.

Does anyone have information about how well these satellite phones operate in a rugged mountain environment? This issue is that there are deeply cleft, at least relatively speaking, valleys in the mountains and this may interfere with line-of-sight communication with the satellites. Is this a problem or something to be concerned about? I can bring this up with the dealer who provides rentals, of course, but their response may be a little biased. If you respond, please distinguish between Irridium and Globalstar satellite phones. The satellite constellations are different between these two services and this may impact the signal availability in the mountains.
