Universal Integrated Circuit Card (UICC)
Definition - What does Universal Integrated Circuit Card (UICC) mean?
Techopedia explains Universal Integrated Circuit Card (UICC)
A big differentiator and advantage of the UICC over the SIM is that it can have multiple applications stored on it because of its inherent processing power and larger storage capacity. The SIM card, on the other hand, is simply a storage device. One of the more important applications in the UICC is USIM (Universal SIM), which identifies the user and the device to the wireless service provider when using standards such as UMTS, HSPA and LTE. Other applications include CSIM (CDMA SIM) for enabling access to CDMA networks and ISIM (IP Multimedia Subsystem SIM) for securing access to multimedia services and non-telecom-related applications such as wireless and automatic payment.
