Document Type and Number:
WIPO Patent Application WO/2021/203235
Kind Code:
A1
Abstract:
A method to maintain network service for a mobile equipment is described. The method includes reading a current integrated circuit card identification (ICCID) value when the mobile equipment supports a hot swap function 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.
