EUICC
eUICC (embedded UICC) refers to the architectural standards published by the GSM Association (GSMA) or implementations of those standard for eSIM, a device used to securely store one or more SIM card profiles, which are the unique identifiers and cryptographic keys used by cellular network service providers to uniquely identify and securely connect to mobile network devices. Applications of eUICC are found in mobile network devices (cell phones, tablets, portable computers, security controllers, medical devices, etc.) that use GSM cellular network eSIM technology.
