    in HW3.0 it's assumed to have changed to simless form.

    do you know how to disassemble SIMcard tray or LTE antenna?

    My understanding and experience, even if you replace the sim, you still have to get Tesla to unlock it to enable the new sim.

    If i am wrong and someone knows how to get a different sim to work. Please let me know, it would help out a ton of military members overseas.

    That thread is five years old and pertains to the Model S. I don’t think any of that applies to the Model 3. I’ve never heard of anyone attempting to remove or alter the SIM on a Model 3.

    Realize that if you change the SIM, you will probably break all of the services Teslas provides. I'm willing to wager that a "Tesla SIM" is validated in order to provide you with Tesla services.

    thank you for your help. my primary purpose is to disconnect the internet by unplugging the LTE antenna or removing SIMcard.
    the second is to use the switch only when I need the Internet. I know it's a strange purpose. It's a must for me :)
    I guess this cable can be a solution!

    I am really curious on why you want to replace it. Coverage problems?

    Your car won't wake from sleep via the app if you change the SIM. A text is sent to the car to wake it. Your cell operator would also have to allow you to use any APN as you wouldn't be able to change the default which is Tesla's ATT APN.

    AFAIK all other features would still work.

    The MCU/APU on the 3 is liquid cooled so you'd have to try to do it without removing the car computer. The link posted here should point you in the right direction. You'd have to remove the connectivity board first then try to get to the SIM. Disconnect the 12v and HV power first if you try this.

    I think he is saying he wants to drive in Stealth mode where nobody can follow him. Similar to turning off any GPS enabling functionality on your iPhone so that it can not track your locations.

    Stationed overseas with my 3. Support from Tesla with our vehicles is limited, no nav, data, etc.

    Sim is out of my car and I'm able to connect and wake the car from the app when it's on wifi. When driving, I put the car in hold before departing and reactivate wifi so I can still stream.

    There is no such thing as "SIMless form".
    All wireless devices are authenticated for valid subscription profile based off credentials stored in a SIM/UICC.
    SIMs can be physical (piece of plastic with a chip), or virtual (code download over the air via eUICC). The latter could also be updated/re-downloaded.

    Why?
    Feeling paranoid?

    That would be every time you drive (navigation, radio streaming, etc)?
    :eek:

    There is no such thing as "Tesla SIM".
    However, if AT&T had configured Tesla's enterprise services to run on a Private Network APN, those would not work with any other off-the-shelf SIM (AT&T's, Verizon's, or T-Mo's).
    Infotainment services, however, would like continue to work, as those are routed over the Internet APN.

    seems like a good way to steal a tesla and disable its location services....

    Odd thing to say, I hope you mean PCS.

    Tesla needs to get it together for vehicles in crappy coverage or people moving overseas or as least into another country. AT&T is crap in my area but Verizon is full bars LTE.

    Ahh I missed that in the OP.

    That was my thought after I realized what was actually being asked. I don't see why else you'd want to do this. If you're that concerned about being tracked, the most connected car on the road may be the wrong choice. You also have multiple bluetooth radios emitting signals, etc...
