Device testing for M2M and IoT

eSIM-enabling Consumer and M2M devices is a multi-levelled process.

It should be part of the design stage of a product, when devices are still on the drawing board and everything from form factor to connectivity profiles are being considered. It’s a key consideration during the final physical roll-out of a fleet of IoT devices. And it’s a consideration for every stage in between.

Consequently, the testing of eSIM devices should take place under many different scenarios. And, as eSIMs enable products and devices to have a life beyond their first ownership or the duration of their first network contract, they present a whole additional set of scenarios that need to be compliance-tested, which are beyond the realm of traditional, physical fixed SIM and SIM-based devices.

The technical requirements for device compatibility with eSIMs are outlined in Annex G of SGP.02 (M2M) and SGP.22 (Consumer). The Cloud 9 test lab provides a device manufacturer with advice and assurance to ensure that their devices are fully eSIM ready.

Why Cloud 9?

Cloud 9 is not only a provider of everything eSIM, it also acts as a partner and consultant to developers, product designers and integrators working with next generation M2M and IoT-enabled devices. It can test and trial GSMA 3.1-compliant eUICC eSIM chips, provisioning via IMSI bootstrap profiles, the deployment – and multiple deployment – of operational profiles and the development and maintenance of subscription management platforms.

Cloud 9 also acts as a partner for achieving GMSA site approval under the Security Accreditation Scheme (SAS) protocol and other related procedures such as the GSMA’s Embedded SIM Test Specification and its Function Compliance Program for eUICCs.

Unlike a large-scale IT network – a mobile workforce using laptops, perhaps – an M2M-based network has the added factor that the connectivity element, in this case the SIM, will be in a device for which the user has no technical knowledge.
Going one stage further, the SIM could be completely inaccessible to the user. Further still, the device could be in a remote unmanned location perhaps acting as a sensor or tracker.
But with an eSIM and a sophisticated subscription management system, none of this is an issue.
