Prepare to be spoiled. Your car’s built-in Wi-Fi^®Hotspot* turns it into a mobile hub with its own Wi-Fi that you and your passengers can connect to. And not just any connection — it’s a super-strong signal with great bandwidth — better than what you’d get from your smartphone. Plus, it’s powered by your car, so you won’t run down your phone’s battery. Your car has to be on or in accessory mode for the hotspot to work.   

Your OnStar account (My OnStar Plans) is where you can see, manage, and change your OnStar plan, and you’ll find plans and pricing info tailored to you. You can do things like add to your OnStar plan, switch to a different plan, and get customer support.  

Anytime, day or night, we’re here for you. You can push your blue OnStar button, or you can call us toll-free at 1.888.4ONSTAR (1.888.466.7827). If you’re deaf, hard of hearing or speech impaired, we have a toll-free TTY number for you: 1.877.248.2080. 

It’s help in just about any crisis situation — severe weather conditions, wildfires, etc. Our Advisors are ready to give you the emergency help you need, like finding a route. We can also get in touch with your family members. 

Think of it as OnStar everywhere you go, not just in your car. It’s an app on your phone, so you’ve always got OnStar when and where you need us. If you’re on a walk, on a bike, on a motorcycle, in someone else’s car — even at home or at work. Even better, you can share the app with up to seven loved ones.* So they’ll have OnStar wherever they need us too.
