Abstract
A universal integrated circuit card (UICC) may include a universal subscriber identity module (USIM); a code division multiple access (CDMA) subscriber identity module (CSIM); a memory to store instructions; and a processor. The processor may execute instructions to determine a type of wireless access network available to a user equipment (UE) associated with the UICC; perform updates of the UICC using the USIM, in response to detecting a CDMA enhanced High Rate Packet Data (eHRPD) network, a Global System for Mobile Communication (GSM) access network, or a Long Term Evolution (LTE) access network; and perform updates of the UICC using the CSIM, in response to detecting an available CDMA access network other than a CDMA eHRPD access network.
