As cellular carriers transition to 4G or 5G connectivity, vehicles using a 2G connection will lose OnStar service. In the U.S., most major network providers will complete the transition in December 2022. After the transition, 2G network connectivity will no longer be provided.
In the U.S. and Canada, certain 2015 model year and older GM vehicles will be affected when 2G networks are upgraded. This also may include former GM brands, such as Pontiac, Saturn and HUMMER.
OnStar Link will enable most of the vehicle’s safety and connected services. Simply plug the device into your vehicle’s OBD-II port and pair the device to the OnStar Guardian™ app.*82 The embedded OnStar hardware and the three-button module in your vehicle will be deactivated, but you’ll have access to key OnStar® safety services and a live Advisor through the Guardian app.
OnStar Link also pairs with your vehicle mobile app. Once you pair either your myChevrolet, myBuick, myGMC or myCadillac app, you can continue accessing your Remote Key Fob — all from your smartphone.
OnStar Link will enable most of the safety and connected services you love — and even some new services.
OnStar Safety & Security
OnStar Link will be available to existing Members starting March 2022.
Starting in March 2022, when you log in to your GM account, we will automatically determine if your vehicle is eligible and prompt you to order the device. The device will be shipped to your chosen address along with setup instructions.
Members who have an active paid service plan will not have to pay for OnStar Link. However, if you do not activate your device within 30 days of receiving it, you will be charged a fee of $99 (includes sales tax) to cover the cost of the device.
Your current OnStar Safety & Security Plan*4 or Essentials Plan*109 will continue to offer most of the same services you have today. You can choose to upgrade your plan to take advantage of new services like Remote Key Fob and in-vehicle data.
Getting started with OnStar Link is quick and easy. The device will come with a Quick Start Guide to walk you through the start-up process in six simple steps.
