The invention relates to a method for resource management in a vehicle-based mobile communications unit in the memory thereof a plurality of activatable identity profiles (201, 202) are stored, each comprising a user specific and a user-nonspecific data component. The mobile communications unit has a modem device (14) by means of which, while using an identity profile (201, 202) in each case, at least two simultaneous mobile communication channels can be established to mobile communication networks (18) which networks can be used to provide mobile communication services of mobile communication services providers, wherein the implementation of the method is automatically implemented by a control unit of the mobile communications unit. The invention is characterized in that during a mobile communication transaction conducted via two simultaneously established mobile communication channels, the user-nonspecific data components of the currently active identity profile (201, 202) are compared with one another to determine the mobile communication services provider currently being used, and in the case of a mobile communication services provider identity determined within the context of the comparison, one of the mobile communication channels is switched off and the mobile communications are conducted via the other mobile communication channel. |
