On vehicles with a built-in communication module, the Internet connection is established via an integrated SIM card.
To use the Internet function, the vehicle must be equipped with a permanently installed communications module.
Additional data volume is required for the "Internet in the Car" service and the associated use of web browsers, Internet Radio or the Wi-Fi hotspot. This can be purchased directly from the mobile phone network provider More.
Contact a Mercedes-Benz Service Centre to find out whether it is possible to purchase data volume in your country.
