Everything about IP Multimedia Services Identity Module
Application residing on SIM card
An IP Multimedia Services Identity Module (ISIM) is an application residing on the UICC, an IC card specified in TS 31.101. This module can be used in UMTS 3G and IMS-based VoLTE networks. It stores parameters used to identify and authenticate the user to the IMS. The ISIM application can coexist with both the SIM and the USIM on the same UICC, allowing the same smart card to be used across GSM networks and earlier releases of the UMTS.. Wikipedia →
