Bear in mind that even if you do succeed in replacing the SIM card with a local one, you still need to modify the APN (Access Point Name). It is not simply a plug 'n play. Tesla "may" be able to provide you with a temporary code and instructions on how to change the APN, if you agree to sign a waiver. But they may also refuse to do so. Get in touch with the Service Centre in Amman or Dubai, and take it from there. Or just go to your local service centre in Germany and "beg" them (with cookies and donuts) to swap the SIM (it should take them less than 5 minutes).
Good luck and keep us updated.
