APPARATUSES AND METHODS FOR PROVIDING MULTI-STANDBY MODE OF WIRELESS COMMUNICATIONS USING SINGLE SUBSCRIBER IDENTITY CARD WITH MULTIPLE SUBSCRIBER NUMBERS

If so, the processing unit activates one subscriber identity module instance in the subscriber identity card for the elementary file, and reads the elementary file from the subscriber identity card.
