OnStar says that personal calling is not available in my area
and they don't know when it will be available. Yet I can talk to Onstar using the system. Does the system use cellular technology even if you press the OnStar button? If not, what does it use to communicate with OnStar (digital satillite?)?
If personal calling is in the area and you drive to some city that it is not available, does it stop working?
Are there any good websites that explain how this all works other than the Onstar site?
