Terminal, SIM-card and telecommunications system for a subsciber as well as method for changing a subscriber related service profile

摘要

The terminal includes an erasable data storage (MEM) in which data for a service profile are stored. The service profile is allocated to the subscriber. A processor (uP) controls the input and output units (KBD,LCD) so that the subscriber can change and output the data for the service profile. Preferably, the data storage is arranged on an authorisation card (SIM) on which the subscriber identification for the subscriber is stored. The terminal includes the card reader (IF) which is connected to the processor. The card reader accommodates the authorisation card for reading and writing the data storage.
