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.

What services do I get with OnStar?
Welcome to OnStar. Where you can get Roadside Assistance* or navigation when you need it, Emergency Services* 24/7, and a vehicle mobile app* that connects you to your car from anywhere. You’ll even discover hands-free driving with Super CruiseTM* and OnStar Smart Driver* to help you boost your safe driving skills.

Can I get OnStar for free?
Here’s how: It starts with your free 30-day OnStar® trial. You’re going to love the experience. So during that 30 days, choose a monthly renewing plan. When you do, the next two months of that plan are complimentary for eligible vehicles* — it will start right after your 1-month trial ends.

Is OnStar exclusive to GM?
Since 2014 OnStar offers LTE Wi-Fi service on select GM cars. Starting June 14, 2021, the OnStar Guardian app was made available to any driver in the United States or Canada.
