How to connect and use Onstar 4G LTE Wi‑Fi Hotspot

Setting Up and Using

The newest feature that Onstar have is that 4G connectivity and allows you to have a living Wi-Fi hotspot through OnStar in your vehicle. The built-in 4G LTE Wi-Fi Hotspot turns your vehicle into a reliable mobile hub, with great signal quality and bandwidth. It provides a better in-vehicle experience than your smartphone. When you press the Onstar button on the panel, you have Wi-Fi settings there. So just like the router in your house you’re going to get a Wi-Fi hot spot name and then it does have a passcode. You can connect up to seven devices to your Wi-Fi hot spot in the vehicle. But you can only access it if you have that password. So you don’t have to worry about the person in the car next to you stealing your your devices and getting in there.

What can you do with that Wi-Fi Hotspot speed?

So once you have that information then it’s just a matter of connecting the tablet so you could have each kid could have a tablet or a phone. When you see that you’re connected, a little Wi-Fi symbols on. It’s actually fast enough to stream Netflix. This is something where you really could have each person in a vehicle be doing something different. If you have your teenager who only wants to be on Facebook, Instagram or play online game the whole time then they can be on their phone. You can connect their phone to the Wi-Fi hotspot. You can be on Facebook, Instagram, other social platforms or online games and not be using up data on your phone. You can be using the data in the vehicle.

  • I have a 2020 Buick Encore GX that keeps alerting that I have active 4G LTE hot spot… but I have no active data plan with Onstar. I asked both a billing rep and a supervisor to put a data block and deactivate any possibility of the message popping it. Minutes after it was resolved on the call, it came back on my car screen that it again was active. How do I disable it?
