What happens if I am in the middle of the desert and I do not have cell service?
OnStar equipped vehicles come with a large roof antenna that’s stronger than that of a cell phone. Where the cellular network signal is weak you might still have a connection, although your cell phone does not. However, please note the OnStar antenna depends on the same kind of (cellular) network as an ordinary cell phone and as such is subject to cellular network coverage and availability. It’s not a satellite phone. Not all services are available everywhere, particularly in remote areas or even deep in basements. See our User Terms for more details.
