What you need to know
  • 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. The decision to sunset these networks was made by the wireless network providers and the need to upgrade to newer technology.

    Certain GM vehicles on the road today currently leverage the 2G network for OnStar connectivity. Once the 2G network sunsets, the three-button interface in your vehicle will be deactivated.

  • 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.
