Standards
The core standards that define eUICC are published by the GSM Association in two topical areas.Consumer and IOT
Core standards for implementing eSIM on mobile devices include the following articles:Machine to Machine (M2M)
GSMA publishes standards for machine-to-machine (M2M) third-party provisioning of eSIM which includes the following articles: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.EID
GSMA standards define EID as "eUICC Identifier". Some developers / implementers have referred to this using the descriptive term "eSIM identifier", which summarizes the function of an eUICC Identifier. Some third parties have joined this acronym with the term "electronic identity document", which is a general concept of any identifier stored or presented in electronic format.References
