ABSTRACT:
Embodiments of the invention include a multiple subscription subscriber identity module (SIM) card. The SIM card includes a plurality of sets of subscription parameters from which to select and activate a single set of parameters. The sets of subscription parameters each contain various information, e.g., information such as an Integrated Circuit Card Identifier (ICCID) and an International Mobile Subscriber Identity (IMSI), and are based on various criteria, e.g., different service regions of use for the electronic device on which the SIM card is installed. A set of subscription parameters is selected for a particular region of use either manually or automatically. The SIM card, which can include a software interface that provides a list of available sets of subscription parameters, is activated by updating the selected set of subscription parameters. Alternatively, a default set of subscription parameters is selected unless a different set of subscription parameters is selected manually from among the plurality of sets of subscription parameters. According to alternative embodiments of the invention, the selected set of subscription parameters can be deactivated and a different set of subscription parameters can be selected and updated to in the SIM card.
