    True, but why does the chip say AT&T? Since the SIM would be AT&T, not the 3G modem itself.

    Yes, but why is that label on there?

    The SIM would be the only thing tying it to a network.

    Now I'm wondering how easy it is to replace this. After all you just need to change the APN settings and it should work.

    Yes please! More bandwidth and lower latency :)

    Still I think the 3G antennas in Model S simply not good.

    See this topic however: No LTE in 2014

    Not that my opinion matters much to Tesla, but I'd think that a 3G->4G/HSPA or in 2015+ 3G-or-4G/HSPA->LTE upgrade would be a wide seller among the existing customer base. There has to be a large percentage of us who would be very glad for faster map downloads and/or web browsing.

    So the SIM is embedded into the module and not separate from the AR8550?

    Looking at your specs... do they imply that the existing module in our existing cars could be running 4G instead of 3G, with no change in hardware?

    I think HSPA is referred to by some as 3.5G. 4G is often used as marketing. What people really want is LTE. It doesn't look like this chip has that.

    This radio chip is rather old. I wonder what the VIN is on the car. Surely, there isn't 2011 technology in a 2013/2014 car ;)

    If this is the case, the radio cannot be upgraded. It looks like Tesla manufactures (or outsources) their own modem boards. As the pictures show, swapping the AT&T SIM with another carrier (MTS in this case) does work.

    Interesting that Tesla didn't go with industry standards on modular telematics gear.

    Of course there is older technology in the car. The chip was released at the end of 2011 for a car going into production in 2012.

    Since the LTE automotive chipsets are just now being sampled by customers... it will likely be next year before we here anything.

    Do you need to pay for data usage or is it paid by Tesla?

    Paid by Tesla, for now and they haven't said anything about when this will stop.

    They announced 4 years free data and Internet radio for new owners and 4 years from January 1, 2014 for those who bought cars before that date.

    Ok. Data roaming is expensive. Hopefully cars are sold with native SIM in every country.

    You would need to change the SIM card to a local carrier, and pay for that access just as if it was a phone or tablet. There's a Facebook page out there that shows someone opening up the dashboard to do this swap. You can also go check out page2 of this thread for more pictures of that install.

    Probably automatic or by pushing the setting by SMS/MMS, most tablets/dongles work that way already.

    You might want to reconsider and purchase from Tesla Denmark directly. Tesla will probably not help you with this. Plus you won't be able to use the superchargers, claim warranty, charge 3phase, etc etc etc. Way to many uncertainties and negatives if you ask me.
