ABSTRACT:
A method for providing and billing WIM functionalities in mobile communication terminals. The method is characterized in that the WIM internally counts each of the signatures initiated by the subscriber, wherein the signature function is blocked when a given number of signatures has been reached. No further signatures are possible until the counter has been reset by means of a release/reload-type operation and a corresponding billing has taken place.
