Cloud eSIM

eSIM and some key barriers to global enterprise adoption

The Cloud eSIM will be essential for the large-scale diffusion and use of 5G. It will allow connected objects to be equipped with constant cellular connectivity and will continuously transform the management of connectivity in companies towards digital-minded enterprises. As a result of these changes, the business landscape we’re experiencing today is uncharted territory, one that is forcing organizations to be agile and adopt zero-touch, digital-first technologies and applications. IoT solutions can help businesses become more efficient and productive, and can also bring in new opportunities and innovations, enabling them to scale new levels of growth.

eSIM is the materialization of this new efficiency, as devices get connected to the mobile network without having to worry about their location and without having to physically intervene on these objects when setting them up or when changing the mobile subscription. However, certain challenges remain in the face of the mass deployment of IoT objects on 5G networks. Cybersecurity, seamless integration, and reliable, robust connectivity and global reach continue to remain key barriers to global enterprise adoption. Hence, manufacturers will have to deal with the high economic costs associated with the technology’s deployment. They will be forced to adapt their objects to the reception of an eSIM and will thus lengthen the implementation cycle of their products. The risks related to the security of objects, currently assumed by companies, is another challenge. The environmental cost associated with the delivery of eSIMs is another factor to consider.


The Cloud eSIM program


The Cloud eSIM program, “called “Velios”, designed by teams from the Oasis Smart SIM’s Aix en Provence R&D center (13) is a ground breaking technological innovation in the field of eSIM authentication, making it possible to meet the constraints of the current form of eSIM (additional material cost for each object, longer design and certification time, environmental cost). The Cloud eSIM simply offers a new paradigm that will rapidly accelerate and simplify IoT deployment for certain use cases.


With the Cloud eSIM, Oasis will offer an entirely digitalized eSIM functionality and virtualize it in a secure cloud architecture, all without modifying existing technologies and infrastructures (communication networks and modems) and enhancing the security of the solution. With Velios, connected objects no longer need on-board SIMs, mobile connectivity is implemented remotely (zero-touch concept) and secure data is no longer stored in the object (zero-risk concept).

Oasis Smart Sim’s cloud-based eSIM will be used in the recently announced end-to-end solution for zero-touch onboarding of cellular-connected IoT devices to cloud services built on Micron Technology’s Authenta™ solution and powered by Tata Communications. This solution will simplify and accelerate large-scale global deployment of internet of things (IoT) devices and the IoT services ecosystem.


Cloud eSIM for IoT


A new level of security

As the threat landscape grows riskier, cybersecurity is a weak link in IoT adoption. To tackle that challenge, the Cloud eSIM is built on Micron’s Authenta silicon root of trust, providing a unique level of protection for the lowest layers of IoT software. Starting with the boot process, Authenta uses strong cryptographic identity and security features baked natively into flash memory. To enable device compatibility with this new SIM, OEMs need only to install Authenta flash; no secure key injection or added secure elements are required.

Leveraging this root of trust, Micron’s cloud-based service Authenta KMS authenticates these IoT devices, allowing them to be activated and managed at the edge. This enables platform-hardening and device protection through the entire lifecycle, from manufacturing to installation. The ease of this security-as-a-service solution is particularly beneficial for traditional manufacturers making forays into connected devices for IoT use cases.


What use cases?

The use cases are numerous:

  • The eSIM Velios can be set up on demand to connect an object on an ad hoc basis (activation of a connected bicycle to geolocate it, to allow the live stream of its on-board camera, to occasionally collect data or at manufacturing stage). This just-in-time delivery reduces customers’ capital and operational expenditures, as compared to physical SIM cards that require activation of service contracts well before shipping and based on fixed monthly contracts.
  • The eSIM Velios introduces a new paradigm of usage based on the number of objects requiring simultaneous connection and no longer on the number of objects deployed. For instance, a manager of a connected vehicle fleet will be able to recycle his mobile telephone subscriptions by limiting himself to vehicles in use. This offers a pay-as-you-go alternative  for objects that do not require permanent connectivity

A Cloud SIM can be used as an eSIM in a connected car thanks to the Velios Link. In this example, the car contains two eSIMs, a physical one (left) and a virtual one (on top), virtually embedded in the car thanks to Velios Link & Velios Client.


Having won the I-Nov competition, Oasis will rely on the financial support of the BPI to finance this project which will create more than 80 jobs in France and should ultimately allow more than 110 million objects to be connected to the horizon 2025.
