  2. SIM Application Toolkit - Wikipedia

    en.wikipedia.org/wiki/SIM_Application_Toolkit

    USIM Application Toolkit (USAT) is the equivalent of STK for 3G networks. [4] USAT takes advantage of the multiapplication environment of 3G devices by not activating until a specific application has been selected, unlike STK which is activated at startup. [13] Some functions are card related rather than application related. [5]

    In a cdmaOne/CDMA2000 ("CDMA") network, the UICC contains a CSIM application, in addition to 3GPP USIM and SIM applications. A card with all 3 features is called a removable user identity card, or R-UIM. Thus, the R-UIM card can be inserted into CDMA, GSM, or UMTS handsets, and will work in all three cases.

    Developing globally applicable standards for communication technologies is the task of standardisation bodies such as ETSI (European Telecommunications Standards Institute, 3GPP (Third Generation Partnership Project) and 3GPP2 (Third Generation Partnership Project 2). In case of the (U)SIM interface, the most important specifications are:

  7. CDMA subscriber identity module - Wikipedia

    en.wikipedia.org/wiki/CDMA_Subscriber_Identity...

    A CDMA subscriber identity module (CSIM) is an application to support CDMA2000 phones that runs on a UICC, with a file structure derived from the R-UIM card. By porting the application to the UICC (Universal Integrated Circuit Card), a card with CSIM, SIM, and USIM can operate with all major cellular technologies worldwide.

  8. IP Multimedia Services Identity Module - Wikipedia

    en.wikipedia.org/wiki/IP_Multimedia_Services...

    The ISIM application can co-exist with SIM and USIM on the same UICC making it possible to use the same smartcard in both GSM networks and earlier releases of UMTS. Among the data present on ISIM are an IP Multimedia Private Identity (IMPI), the home operator domain name , one or more IP Multimedia Public Identity (IMPU) and a long-term secret ...
