Method of operating a mobile communication device with the capability of using the internet, with the steps: - determination (S10, S12) of at least two situation profiles through the determination of specifications, wherein two different profile situations differ through one specification, through which the extent of internet usage when using the internet is determined in accordance with the relevant situation profile, wherein at least one situation parameter is assigned to each situation profile, through which a situation is defined, which for all situation profiles is different in each case, - before or during use of the internet by the mobile communication device, determination of at least one situation parameter relating to a current situation and downloading of data from the internet (S16, S18) to an extent that is predefined by the situation profile assigned to the at least one situation parameter, wherein the situation profiles are stored in a central dataprocessing installation in a user account, wherein through a user of the mobile communication device the situation profiles are set, wherein - the situation profiles are called up from the user account by the mobile communication device as a function of a situation parameter which the user indicates, and wherein - a situation parameter serves to classify a location of the mobile communication device which is recorded by a position recording device, characterised in that - in the method a data connection between the mobile communication device and a vehicle is established and for calling up situation profiles from the user account transfer of the identification of the vehicle to the central dataprocessing device and comparison with the identification stored there take place, wherein - through the user a situation profile for a first location and for a second location a different situation profile is set, wherein - after the start of travelling the vehicle is located at a first location and use of the internet takes place in accordance with the situation profile for the first location and - when the vehicle continues to travel the vehicle is located at a second location and use of the internet takes place in accordance with the situation profile for the second location, wherein - at the first location the vehicle is located in its home country and at the second location is located abroad, wherein - the different situation profiles a) differ in terms of the number and resolution of images to be downloaded when using the internet, wherein the number is determined by a scale of a depicted map if maps are downloaded for a certain travel route, and/or b) differ in terms of a bit rate when downloading audio files. -
