iSIM Secure Connect

Manage eSIM and iSIM technologies with ease

What’s next in the evolution of SIM cards?

The Subscriber Identity Module (SIM) has long been the method of storing user credentials on a mobile handset and using those credentials to authenticate the user on the network. As a function, secure digital identity is only becoming more critical. But as the world gets more connected, the removable SIM is no longer the best way to manage it. In its wake are coming two more IoT-compatible SIM formats: embedded SIM (eSIM) and integrated SIM (iSIM).

Embedded SIM and integrated SIM

The embedded SIM (eSIM) technology is a hardware-based SIM designed to address some of the challenges impeding true scalability in cellular IoT. Compared to classical SIM cards, eSIM can store multiple operator profiles instead of only one. These profiles can be remotely updated, extended or deleted with a remote SIM provisioning (RSP) tool. It allows devices to be deployed anywhere with existing cellular coverage.

But there’s more: an integrated SIM (iSIM) is a software-based SIM that takes all the benefits of a standards-compliant eSIM and embeds them into the device’s permanent hardware array by combining the SIM with the system-on-a-chip (SoC) architecture and cellular modem. It provides lower footprint and introduces extra layers of security through a hardware-based secure enclave that maintains the integrity of all cryptographic and key managed operations.

Enabling secure digital identity on a massive scale

Nestled deep within the processor’s system-on-chip (SoC) architecture, iSIM is set to be the technology that allows mobile and IoT devices to securely authenticate themselves to a wide array of eServices, laying the foundations for seamless exchange of data in a hyperconnected world. With the right management solution, companies, governments and service providers could use those capabilities for all kinds of applications.

What is remote SIM provisioning (RSP)?

Remote SIM provisioning (RSP) and remote SIM management (RSM) offer a quick, secure and highly scalable way to manage network operator profiles on mobile and IoT devices over-the-air, eliminating the need to physically access devices and change SIM cards. Service providers can benefit from the new SIM form factors, embedded (eSIM) or integrated (iSIM), which make the on- and offboarding much more flexible and reliable.

GSMA specifies two RSP solutions, one for consumer applications and one for machine-to-machine (M2M) applications.

Why choose Nokia?

Nokia iSIM Secure Connect is a seamless automated provisioning solution that lets CSPs and enterprises manage iSIM and eSIM subscriptions in consumer and machine-to-machine (M2M) devices.

With automated management of the eSIM and iSIM lifecycle, you can significantly speed up new service delivery, improve customer satisfaction, and increase operational efficiencies.

By being technology agnostic and working in various network and cloud environments, iSIM Secure Connect supports your current and future IoT business and operating models, use cases, and monetization strategies.

Expand your customer base and offer new mobile and IoT services capitalizing on the massive growth, while keeping the integrity of your network protected

Manage the entire eSIM and iSIM lifecycle remotely to accelerate new service creation and support service differentiation

Gain significant time, effort and cost savings via subscription management ownership and automation, increasing the overall efficiency and return of investment (ROI)

The power of 5G with eSIM and iSIM

5G is a next-generation technology compared to 4G also in terms of use cases, security and the number of objects connected to the network. With the growing number of IoT devices, cellular connectivity through eSIM and iSIM will become the new standard. 

The combination of 5G, massive IoT, eSIM and iSIM technologies creates disruption in the market – it empowers digital citizens to use their mobile and IoT devices as a secure ID token for almost everything from opening a bank account to logging into the exercise bike at the gym. 

For enterprises, it unlocks a range of IoT applications and partnership opportunities for faster return-on-investment (ROI). For communications service providers (CSPs), it opens up new revenue streams by leveraging on the massive IoT growth. From a use case perspective, it enables new possibilities that weren’t possible before with previous technologies or SIM standards: connected cars, commercial good tracking, smart cities, remote surgery and so on.

How does remote eSIM and iSIM management work in smart water metering?

Water utility is a great example of industries that can significantly benefit from improved remote monitoring and provisioning of their assets. Water is one of the most precious and valuable resources so managing the effective distribution and metering of water is critical.
