eUICC 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.[citation needed] 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.
Standards
The core standards that define eUICC are published by the GSM Association and include the following articles:[1]
- SGP.21, ‘eSIM Architecture Specification’, version 3.0, 28 March 2022
- [1] eSIM IoT Architecture and Requirement Specification, version 1.0, 19 April 2022
- SGP 22, ‘Remote Sim Provisioning(RSP) Architecture for consumer Devices’, version 2.4, 28 October 2021
Implementation
eUICC can refer to any implementation or application of the eUICC standards in an eSIM device. Each implementation of eUICC includes software code, a processor to emulate the software, non-volatile memory used to store the unique identifiers and cryptographic keys that are part of a SIM profile, and a bus interface to communicate the SIM profile to the mobile device. eUICC standards specify that only one eUICC security controller (ECASD) may be implemented in an eSIM, but the eSIM may store multiple SIM profiles.[2]
