Why is OnStar being discontinued?
The reason for this change is the upgrade of cellular carriers from a 2G network to a 4G or 5G connectivity. As older GM vehicles use a 2G connection, these cars will lose their in-car OnStar services. In the US, most major network providers will complete the transition from the 2G network in December 2022.
