has an agreement with a wireless service
provider for service in that area. The
wireless service provider must also have
coverage, network capacity, reception, and
technology compatible with OnStar or
connected services. Service involving location
information about the vehicle cannot work
unless GPS signals are available,

design and architecture of the vehicle,
damage to the vehicle in a crash, or wireless
phone network congestion or jamming —
