Why do I need OnStar Link?

As cellular carriers transition to 4G or 5G connectivity, vehicles using a 2G connection will lose OnStar service. In the U.S., most major network providers will complete the transition in December 2022. After the transition, 2G network connectivity will no longer be provided.

How does OnStar Link help keep me connected?

OnStar Link will enable most of the vehicle’s safety and connected services.

Do I need a smartphone with me in order for OnStar Link to work properly?

OnStar Link works in tandem with the OnStar Guardian app. Once you plug it in and connect to the Guardian app, you’ll have help in a crash, an emergency or a vehicle theft. Plus, when you add Connected Services, you’ll have access to your vehicle mobile app, which allows you to unlock and lock your vehicle right from your smartphone.

To use all of these services, your smartphone is needed. It also ensures you have access to an Advisor through the OnStar Guardian app.

If you do not have your smartphone with you and you are in a crash, OnStar Link can still alert an OnStar Emergency-Certified Advisor*64 who can request help be sent to your location.
