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 WLAN 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.
