Hello, I bought an EQE5004Matic in Germany and brought it to Austria. Now the “third-party provider data volume” does not work. In this regard I had a detailed conversation with the me Support today. If a German car imports to Austria (or Switzerland, ..), then the IITC Internet in the Car of Mercedes me does not work! According to support the cars for Austria get their own SIM card. With the for DE then nothing works. E_SIM is, but hardware of His time which is deliberately built for security reasons so that you can hardly get any more. A conversion is not planned. Now I have a car worth well over Euro 100,000.- and it is not possible to use the MB entertainment package, despite connection to A1, but no data volume!!??? You are not told about it. Then I was asked why I bought the car in DE and not in AT, ha, ha. Welcome to of the EU!
