in need of satellite phone

[Beastmaster]

Yes, OnStar uses standard cell service through Verizon. The other major issue is that by 2008, OnStar has to go all digital.

This means that unless you can reach a digital cell site, you're stuck.

I've been in the boonies where Verizon, Cingular, Alltel, T-Mobile, and even analog doesn't get you anywhere, but Satellite phones will.
