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.
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.
I am really curious on why you want to replace it. Coverage problems?
soldiers can't use the tesla because of GPS?
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.
in HW3.0 it's assumed to have changed to simless form.
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'm willing to wager that a "Tesla SIM" is validated in order to provide you with Tesla services.
Stationed overseas with my 3. Support from Tesla with our vehicles is limited, no nav, data, etc.
sometimes unexpected things happen to soldiers
seems like a good way to steal a tesla and disable its location services....
