Abstract: A method is described in which a number of subscriber profiles are flexibly allocated to a subscriber identity module. The subscriber has a subscriber identity module in his terminal. The terminal is also associated with a subscriber identity number. However, the subscriber identity number can be associated with two or more directory numbers that are distinguished by different associated subscriber profiles. The subscriber profiles are available and can be administered in a suitable manner in the network. Depending on the current status of the profile (activated/deactivated), a mobile-terminated call is switched through or diverted, e.g. to a so-called “voice mailbox”, that is to say an answering machine.
