SIMalliance Test Specification Improves Interoperability of M2M and IoT Deployments


SIMalliance, the global non-profit industry association which simplifies secure element (SE) implementation to drive secure mobile services, has published a test specification which will promote greater interoperability for remote SIM provisioning and subscription management across machine-to-machine (M2M) and consumer devices.


The newly released eUICC Profile Package: Interoperable Format Test Specification v2.0, reassures embedded UICC (eUICC*) manufacturers and users, including mobile network operators, that their subscription profiles will be correctly interpreted and implemented by the eUICCs they are provisioned to. Device makers who integrate eUICCs into their solutions will also benefit from the certainty that they are using compliant products.

The test specification aligns with the recently updated eUICC Profile Package: Interoperable Format Technical Specification v2.0, and provides a globally standardised means of testing products which implement the latter specification.

The eUICC Profile Package: Interoperable Format Technical Specification describes a common coding process for subscription data to be built, remotely loaded and installed into any embedded UICC (eUICC*), by any SIM vendor on behalf of any MNO.  It is referenced in the GSMA Embedded SIM Specification, specifically within the Remote Provisioning Architecture for Embedded UICC Technical Specification v3.1. Within that document, the GSMA defines a technical solution for the remote provisioning and management of the eUICC in M2M devices

Hervé Pierre, SIMalliance Chairman, comments: “This test specification offers assurances of interoperability across the remote provisioning ecosystem and demonstrates SIMalliance’s continuing support of the GSMA Embedded SIM Specification. The availability of a test specification, which eliminates ambiguity in how the technical specification is interpreted, also indicates the stability of remote provisioning technology.  This maturing ecosystem will only serve to further accelerate the adoption of M2M and IoT deployments, as it enables subscriptions to be loaded and managed remotely, across devices already deployed in the field, in a proven, interoperable way.”

All SIMalliance eUICC resources are available, free to download, from the resources page on the SIMalliance website.  SIMalliance continues to invite industry feedback on its eUICC resources. Comments should be sent to
