    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...

    I don't know about the phone number, but yes you can Bluetooth to your home wifi to receive updates and the car will encourage you to set it up.

    I have similar cell coverage issues at my house and I also have an AT&T Microcell installed but my Tesla is not connected to it. It uses the wifi perfectly and that's how I get my updates when it's parked in the garage. I think you will be fine without adding it to your Microcell if you have a good wifi signal in the car. Good luck!

    There's a SIM card on the radio inside the console computer.

    What if you put that in your phone, and turned it on? Would it link up enough to display a phone number?

    If the SIM card is removable that is a brilliant solution. And once I know the number, I wonder what would happen if I called the car? :)

    I'll know soon enough; my car went into production today

    Right, so all you have to do is pry off the 17" and take a peak. Please take pictures

    I can't say i'm eager to pry off the monitor; I think I'll let the SC folks figure this out for me.

    There is no benefit if you have wi-fi. I wouldn't worry about tit.

    You're confusing Bluetooth with Wi-Fi. They're different, and Bluetooth (at least in the car) has nothing to do with network connectivity, either over Wi-Fi or 3G/LTE.

    I'm not sure what your expectations of the Tesla Service Centers are, but I can assure you that they would never tear down the dash and remove/reinstall the touchscreen/MCU just so you can access the SIM card to retrieve the phone number.

    Especially when wi-fi is all you need.

    I thought the cell radio was in electronics pod up behind the mirror.

    By "letting the SC figure this out..." I didn't mean disassembling anything, only that if they could determine the tel number some other way. If not, no problem.

    Just connect to wifi, end of story. Extend your wifi if needed, and/or have it connect to a broader range 2.4ghz signal if needed, etc.
