Registering a replacement Onstar Unit
Begin the registration process by recording the replacement units STID and ESN serial numbers located on the unit label. Next, with the ignition switch turned ON (II), press the OnStar services button to connect to the OnStar call center. When the OneStar agent answers, provide the replacement unit's STID and ESN serial numbers. The agent will provide you with further instructions.
Cellular network issues are indicated by, but not limited to, error messages like, "Your cellular number is not recognized" or "Please enter your credit card number now", etc.
Messages like these indicate the replacement unit's MIN or ESN is not being resolved by OnStar Technical Support.
If you cannot connect to the OnStar call center from the vehicle and the OnStar status light is solid or blinking red, see ONSTAR PANEL BUTTONS AND LIGHTS .
