Monterey: After reading the following I believe OnStar's satellite usage is just for GPS tracking. The actual connections are made through AT&T's wireless network.

How Does OnStar Work?
Each OnStar system that’s installed as original equipment is capable of gathering data from both the on-board diagnostics (OBD-II) system and built-in GPS functionality. They also use CDMA cellular technology for voice communications and data transmissions. Since OnStar subscribers pay a monthly fee for the service, there are no additional additional charges from the carrier that handles the voice and data connection. However, additional charges are incurred for hands-free calling.
In order to provide turn-by-turn directions, GPS data can be transmitted via the CDMA connection to the central OnStar system. The same GPS data can also be utilized for emergency services functionality, which allows OnStar to summon help in case of an accident.
