The eUICC Profile Package: Interoperable Format Test Specification version 3.3.1.2 has the objective of testing if a profile is correctly interpreted and correctly loaded on an eUICC.

It includes tests for eUICCs supporting IoT minimal profile. It provides a globally standardised means of testing products which implement Version 3.3.1, Version 3.2, Version 3.1, Version 2.3.1, Version 2.2, or Version 2.1 of the eUICC Profile Package: Interoperable Format Technical Specification.

The Profile Elements defined in the test specification are provided separately in ASN1 format. It is mandatory to use the ASN1 files for the creation of the DER codes.

The Specific_ASN1_definitions shall be used when creating the DER code for Test Case 8.2.11.4 (check unknown tag in Profile Package) at least for the DF-CUSTOM-by-Generic-File-Management-4 profile element.

The Test Applets used in the Profile Packages are provided as an informative attachment of the specification.

The objective of the Interoperable Format Technical Specification is to define the technical specification of a standard format to be used for the loading and installation of an interoperable Profile Package in any compliant eUICC.

This specification is based on the following Trusted Connectivity Alliance document: eUICC Profile Package: Interoperability Functional Requirements. Major updates have been made to the specification to support full alignment with 3GPP Release 18, including the support of Slice SIM (SSIM) allowing authenticated access to a 5G network slice using proven eUICC security. It also includes clarifications and guidance to further promote eSIM interoperability.

The embedded UICC (eUICC), and the subsequent requirement for remote provisioning, has introduced the need for several operations previously carried out in personalisation centres by individual UICC vendors, to be performed remotely in an open ecosystem.

This document specifies the structure and coding required to build, remotely load, and install a profile in an eUICC.

It is intended primarily for Profile Creator providers, Profile Creator users (i.e., Mobile Network Operators or MNOs) and eUICC vendors for them to elaborate and exchange profiles with guaranteed interoperability.

The Profile Package, as technically specified in this document, represents the structure of data to be built by the Profile Creator and to be loaded in the eUICC for the eUICC to be personalised according to the content of the Profile Package.
