Building a custom remote SIM provisioning infrastructure made easy – Full control over soldered eSIMs

At the MWC, the world’s largest gathering for the mobile industry held in Barcelona, 26 February – 1 March 2018, Comprion shows the newest products in the field of eSIM and Remote SIM Provisioning (RSP).

Comprion SM-SR (Subscription Manager – Secure Routing) and Comprion SM-DP (Subscription Manager – Data Preparation) provide GSMA SGP.02-compliant functionality, enabling especially Mobile Virtual Network Operators (MVNOs), service providers, and manufacturers of mobile IoT devices with eSIMs, for example, from the areas of smart living, automotive, or logistics, to build their custom remote SIM provisioning environment and thereby maintain control over their soldered eSIMs.

Introducing the eSIM – What is it all about?

Olaf Rethmeier, Comprion’s product manager of M2M solutions, explains: “We have observed that many MNOs and MVNOs are preparing their mobile radio infrastructure for eSIM and RSP technology. With the integration of eSIMs into M2M devices, provisioning and changing the subscription data are performed remotely via the operator profile, this means the air interface.

The GSMA has defined an M2M infrastructure and fixed roles (SM-DP, SM-SR, MNO, EUM, eUICC) including their functionality, so that access data of the mobile network can be exchanged securely between eSIM and subscription manager. This makes sure that changing the operator and the related communication works according to uniform standards and that the system is compatible with different eUICCS, servers, and MNO network architectures.”

RSP infrastructure – Easy integration instead of implementation by yourself!

In order to facilitate upgrading the infrastructure according to SGP.02 for network operators and service providers, Comprion now provides RSP functionality by SM-DP and SM-SR implementations as complete modules. “These modules can be integrated into the existing system without the need of the operator to implement the very complex RSP functionality by himself,” explains Rethmeier.

But also manufacturers of mobile IoT devices with eSIMs have an interest in operating their own RSP servers: “Thus, control over eSIM data is maintained by them and not by the network operator,” adds Rethmeier.

Comprion SM-SR and Comprion SM-DP support all procedures defined in GSMA SGP.02, follow the functional requirements needed for a GSMA SAS certification, and are available now.
