Hi there. If you haven't already, the first step to activating your OnStar services is to push the blue OnStar button in your vehicle. Be sure you have power to the vehicle and that it is stationary and parked. From there, an enrollment Advisor will be happy to assist you. If you have already done this, then be sure your OnStar account is linked to your GM Account at experience.gm.com and you are using the correct email to sign into your app. Should you have any specific questions or continue to experience issues, feel free to email socialmedia@gm.com for further assistance.
