A method for switching a Universal Integrated Circuit Card (UICC) transmission protocol includes: setting an operational mode of the UICC to an ISO 7816-12 USB UICC transmission protocol mode (USB mode); and in response to a user input, enabling the UICC to fallback from the USB mode to an ISO 7816-3 T=0/T=1 transmission protocol mode (ISO mode).

Aspects of the present disclosure are directed to a user equipment having a universal integrated circuit card (UICC), multiple baseband modems, and routing logic for handling communications between the UICC and the baseband modems, and methods for operating the user equipment in which the routing logic arbitrates communication between the UICC and the baseband modems in accordance with arbitration logic. Other aspects, embodiments, and features are also claimed and described.

Apparatus and method with routing logic for communications between multiple baseband modems and a universal integrated circuit card

Systems and methodologies are described that determine whether to communicate an update message to a UICC. A UE may be equipped a status update message from at least one of a first radio access technology (RAT) module supporting a first RAT and a second RAT module supporting a second RAT. The first RAT and the second RAT are different. Further, the UE may be equipped to determine whether to generate a universal integrated circuit card (UICC) update message to update a UICC by applying one or more RAT arbitration factors to the received status update message. The UICC includes current UICC status information associated with a current RAT. A status update message may include, a service status, RAT information, and location information, and the UE may apply the RAT arbitration factors to at least a portion of the status update message.
