กำหนดอินเทอร์เฟซทางกายภาพ ไฟฟ้า และตรรกะของ Universal Integrated Circuit Card (UICC) สำหรับแอปพลิเคชันโทรคมนาคม

ETSI TS 102 221 defines the physical, electrical, and logical interface of the Universal Integrated Circuit Card — the chip platform that hosts the SIM and USIM applications in mobile devices. It standardises the card's command set, file system, and electrical classes, allowing a single UICC to run multiple telecom and value-added applications. The specification underpins every removable SIM and is the foundation later extended for embedded and integrated SIM forms.
