Handling of Subscriber Identity Module (SIM) Cards with Multiple Profiles

摘要

Various embodiments provide methods implemented on a mobile communication device for generating a database of information associated with a plurality of profiles associated with a SIM installed in the mobile communication device in order to enable the device to efficiently switch between profiles by utilizing the information stored in the database. In various embodiments, the mobile communication device may populate the profile database with information, data, and/or values needed to acquire service/camp on a network for each of a plurality of profiles associated with the SIM by activating each profile, collecting such service information associated with each activated profile, and storing the service information in the profile database for use in switching between the plurality of profiles at a later time. Specifically, by using information already determined to be relevant to and/or necessary for acquiring service with a profile, the mobile communication device may switch to that profile quickly.
