In the WCDMA system, video calls are possible, multimedia services such as high-speed data and video are possible, and free global roaming is possible. In such a WCDMA system, a mobile subscriber must mount a Universal Subscriber Identify Module (USIM) card in the mobile terminal in order to use a mobile communication service. In the second generation of CDMA systems, user identity module (UIM) cards are optional, but in WCDMA systems, USIM cards are mandatory.

The Universal Subscriber Identify Module (USIM) card is a smart card, also called a Universal Integrated Circuit Card (UICC), and includes a microprocessor, memory, card operation system (COS), security algorithms, and electronically erasable (EPEPROM). Programmable Read Only Memory). The USIM card stores various profile information such as phone number, subscriber authentication key, password (PIN), call time, billing information, financial information, emergency call information, and language setting information.
