  • UNIVERSAL INTEGRATED CIRCUIT CARD (UICC) SERVICE
    Publication number: 20230107560
    Abstract: A method to maintain network service for a mobile equipment includes reading a current integrated circuit card identification (ICCID) value when the mobile equipment supports a hot swap function and a remove interrupt is not triggered by hardware in response to a polling error triggered by a universal integrated circuit card (UICC). The method also includes comparing the current ICCID value to a cached ICCID value captured during a UICC initialization. The method further includes maintaining a current state of the UICC when the current ICCID value matches the cached ICCID value.
