Claim:
1. A communication apparatus, equipped with at least one subscriber identification module (SIM) cards, the communication apparatus comprising: a detector, arranged to detect an amount of the SIM card(s) inserted on the communication apparatus; and a processor, providing different man-machine interfaces (MMIs) to be displayed on a display apparatus according to the amount of the inserted SIM card(s); and wherein when the amount of the inserted SIM card(s) equals to one, the processor provides a single card MMI for a subscriber; when the amount of the inserted SIM cards is larger than one the processor provides a multi-card MMI for the subscribers; and the different MMIs is displayed based on the predetermined SIM card without displaying an option for SIM card(s) not inserted, wherein when the amount of the inserted SIM cards is larger than one and a communication request corresponding to an application is initiated by the subscriber, the processor detects whether the communication request has the predetermined SIM card, wherein each of the different MMI comprises an application controller, the application controller comprises a first part and a second part, and the second part comprises the candidate identification symbol and the first part comprises an icon of the predetermined SIM card, when the communication request with the predetermined SIM card is initiated by the subscriber, the processor respectively displays the predetermined SIM card and a candidate identification symbol on the application controller; or when the communication request without the predetermined SIM card is initiated by the subscriber, the processor displays the candidate identification symbol on the application controller, the first part of the application controller comprises a functional icon corresponding to the communication request, and when the processor detects that the subscriber has selected the functional icon, wherein if the processor has detected the predetermined SIM card exists and a non-predetermined SIM card is not selected by the subscriber, the communication apparatus executes an operation corresponding to the functional icon by the predetermined SIM card; if the processor has detected the predetermined SIM card exists and the non-candidate identification symbol has been selected by the subscriber, the processor of the communication apparatus sends an indication signal to indicate the subscriber that a non-predetermined SIM card is selected; and if the processor has detected the predetermined SIM card does not exist and the candidate identification symbol has been selected by the subscriber, the communication apparatus executes the operation corresponding to the functional icon by the non-predetermined SIM card.
