Abstract
An electronic device and a method for managing an IC card with multiple SIM profiles is described. The electronic device comprises: i) an integrated circuit (IC) card domain, configured to store a first SIM profile and a second SIM profile, and ii) a communication domain coupled to the IC card domain via a physical interface. The IC card domain is configured to: a) generate a first logical interface on the physical interface and associate the first SIM profile with the first logical interface by providing a first logical interface identifier, and b) generate a second logical interface on the physical interface and associate the second SIM profile with the second logical interface by providing a second logical interface identifier. The communication domain is configured to: a) address the first SIM profile using the first logical interface identifier in parallel and independent of the second SIM profile and b) address the second SIM profile using the second logical interface identifier in parallel and independent of the first SIM profile.
