A telecommunication apparatus adapted to be used with a detachable memory device is disclosed. The detachable memory device such as an IC card are capable of storing information relating to a particular user. When the detachable memory device is connected to the apparatus, the apparatus retrieves information relating to the particular user out of the detachable memory device. Thereafter, the apparatus may perform one or more of functions on the basis of the retrieved information. When the detachable memory device is connected to the telecommunication apparatus, the apparatus detects the presence of identification information stored in the detachable memory device.
