Cell coverage at my house is spotty, so I have installed an AT&T Microcell for our phones and visitors. To grant access to it for my soon-to-be-delivered Tesla I need the car's tel number. Does anyone know how to determine this? Or, does it matter? I have great wi-fi in the garage, so that's not an issue; can all the updates come via wi-fi if the car's cell is offline?
Thanks...
