What is an "SSID" or "passphrase?"

The SSID is the name of the Wi-Fi hotspot for the vehicle, and the passphrase is the password associated with the hotspot. The SSID will be used to identify which Wi-Fi hotspot you connect to, and the passphrase will be entered to complete the connection.

How do I get my Wi-Fi hotspot username and passphrase?

To get your hotspot name (SSID) and password, press the voice command button and say "Wi-Fi settings."

Can I change the SSID and password for my Wi-Fi hotspot?

You can change the name of your hotspot and password by pushing the blue OnStar button and asking your Advisor. You can also change them in your vehicle’s mobile app.

Do I need a data plan to use the vehicle's Wi-Fi hotspot?

Yes, a data plan is required to use the vehicle's Wi-Fi hotspot. Data plans are provided by AT&T.

What is the OnStar Data Trial?

Members receive 3GB of data good for 3 months (whichever comes first) with the purchase of an eligible, Wi-Fi hotspot-equipped Chevrolet, Buick, GMC or Cadillac.

How can I find out how much data I have remaining?

You can check how much data you have remaining on your myBuick, myCadillac, myChevrolet or myGMC mobile app, or by pushing the blue OnStar button and asking an Advisor.

Why do I need a vehicle data plan for the Wi-Fi hotspot if I have a personal hotspot available on my smartphone?

The built-in OnStar Wi-Fi hotspot provides a better in-vehicle experience than your smartphone. Our stronger signal means you have a fast and more reliable connection. It is powered by your vehicle, so you’re not reliant on a mobile device battery, and you can access your hotspot up to 50 feet from your vehicle.

What types of data plans are available?

OnStar offers a variety of monthly and one-time use plans to suit your data needs. Visit Plans & Pricing for plan information. Data plans are provided by AT&T.

Does my vehicle need to be running for the Wi-Fi hotspot to work?

The vehicle ignition needs to be in the “Run” or “Accessory” position for the Wi-Fi hotspot to be active.

How many devices can be connected to Wi-Fi hotspot?

Up to seven devices can be connected simultaneously to the Wi-Fi hotspot.

What is the range for the in-vehicle Wi-Fi hotspot?

The Wi-Fi hotspot has a range of up to 50 feet from your vehicle.

Why does my Wi-Fi hotspot internet connection sometimes run slow or show that no internet connection is available?

The coverage for the in-vehicle Wi-Fi hotspot depends on the wireless carrier network coverage. When you are in areas where coverage fluctuates, performance may be impacted. In a 2G-coverage area, the Wi-Fi hotspot will not work. In a 3G-coverage area, streaming data or video to your devices may result in the degradation of your service. View the coverage map.

Also, the vehicle ignition needs to be in the “Run” or “Accessory” position for the Wi-Fi hotspot to be active.

How do I find out if my vehicle is Bluetooth-equipped?

Visit GM Total Connect or push your blue OnStar button and ask your Advisor.
