A digital processing device capable of receiving an additional service is disclosed. In one aspect, a digital processing device includes i) an input unit, inputting a signal, ii) a subscriber identity unit, storing an identity code of a communication operator and generating a communication network access request message, iii) an additional service identity unit, storing an identity code of an additional service operator and generating an additional service request message and v) a control unit, generating a control signal allowing one of the subscriber identity unit and the additional service identity unit to be selectively driven. In accordance with at least one inventive embodiment, a user of the digital processing device can receive an additional service without his or her subscription to a specific communication operator and use various additional services in addition to the additional services provided by the subscribed communication operator.

Digital device and method for providing additional service by using the same

Disclosed is a system for downloading an application from a server and providing the same to a client by using a short message or a subscriber interface module (SIM) card. The system modifies a function key for each application according to a client's selection, and randomly modifies a user interface used for selecting an application. The system extends a usage range of the SIM card. The system periodically checks and analyzes the client' use log for a predetermined time, presents at least one application to the client according to the analysis result on the use log, provides a single application selected by the client to the client, and updates at least one application stored in the client mobile terminal according to the analysis result on the use log. Therefore, the system increases service satisfaction for the client.
