Abstract
Abstract Method and apparatus for sharing a SIM card between two masters. The invention may be embodied in so-called multi-mode radiotelephones that use SIM cards to store and access information. The multi-mode radiotelephone includes at least two master components and a single SIM card. The method and apparatus synchronizes and coordinates communications from either master component directly to the SIM card, thereby allowing a single SIM card to directly service two master components.
