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, push 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 in the Wi-Fi® Hotspot menu listing of your vehicle’s mobile app.*26 You can also visit your vehicle Owner Center and select Manage Wi-Fi Hotspot in the Quick Help section.

Do I need a data plan to use the vehicle’s available 4G LTE 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 Data Trial?

Members receive one month or 3 GB of 4G LTE data (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 with your myBuick, myCadillac, myChevrolet or myGMC Mobile App.® You can also visit your vehicle Owner Center and select Manage Wi-Fi Hotspot in the Quick Help section. Additionally, with certain service plans, you can push the blue OnStar button and ask an Advisor.

Why do I need a vehicle data plan for the available 4G LTE Wi‑Fi® Hotspot if I have a personal hotspot available on my smartphone?

The built-in 4G LTE Wi-Fi® Hotspot provides a better in-vehicle experience than your smartphone. The strong 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 (vehicle must be on or in the accessory position for Wi-Fi to function) from your vehicle.

What types of data plans are available?

The Unlimited Access Plan*3 and Unlimited Access + Safety & Security bundle both offer unlimited data at up to 4G LTE speed. Visit Plans & Pricing for plan information. Data plans are provided by AT&T.

Does my vehicle need to be running for the available 4G LTE 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 the available 4G LTE Wi-Fi® Hotspot?

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

What is the range for the available in-vehicle 4G LTE Wi-Fi® Hotspot?

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

Why does my available 4G LTE Wi‑Fi® Hotspot internet connection sometimes run slow or show that no internet connection is available?

The coverage for the built-in 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.
