Frequently Asked Questions

[H3]
What is the Wi-Fi Hotspot?®

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.

[H3]
What is in My OnStar Account

Your OnStar account (My OnStar Plans) is your hub for managing your OnStar services. Here you can view, update, and change your plan, explore personalized plan and pricing options, add or switch plans, and connect with Customer Support.

What is Crisis Assist?

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.

[H3]
What is the OnStar Guardian® app?

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.
