Kigen iSIM
Deploy ubiquitous connectivity with iSIM:
iSIM makes it cheaper for chipset and device makers to integrate cellular connectivity into IoT designs whilst offering all the advantages of eSIM.

What is an integrated SIM (iSIM)
iSIM is the next generation of SIM technology with the potential to revolutionize cellular IoT connectivity forever. It moves the SIM from a separate chip into a dedicated silicon area which sits alongside the application processor and/or cellular radio on a purpose-built system-on-chip (SoC).
98% smaller
iSIM is significantly smaller than eSIM, reducing the circuit board footprint and releasing more valuable silicon real estate.
>50% cheaper
Fewer components and simplified PCB design help reduce manufacturing and logistical costs. This offers the potential of significant savings for large-scale IoT deployments.
70% Less power
iSIM can massively reduce the standby power consumption compared to multi-chip designs, which is a real game-changer for devices with a built-in lifetime battery.
Flexible subscription deployment models
iSIM can support either a classic SIM OS providing a fixed network subscription or an eSIM OS with the flexibility to have the subscription changed for a manufacture-once ship-anywhere model.
Industry standardised
Just like SIM and eSIM, iSIM conforms to industry standards and offers an equivalent level of protection for subscription credentials.
Additional capabilities
Integrated at the heart of the device and securely personalized, iSIM can act as a root-of-trust for payment, identity and critical infrastructure applications.
Building a secure system-on-chip (SoC) with iSIM
Building a secure SoC with iSIM requires a SIM or eSIM OS implemented on a Secure Enclave that is integrated into a System-on-Chip (SoC) and uses the devices non-volatile memory. We offer a full software solution, integrated with many market-leading Secure Enclaves from Kigen’s vast network of partners, to build iSIM in ultra-fast time.
Can iSIM support remote SIM provisioning?
Absolutely. We recognize that for IoT to scale, it must have cost-effective ways to remotely manage connectivity subscriptions. Our iSIM is flexible enough to support either a single profile or remote SIM provisioning mechanisms, with the latter enabling out-of-box connectivity, secure and remote profile management; even for the tiniest of IoT devices.
Is iSIM secure?
Yes, from both a physical and logical perspective. Going above and beyond an eSIM, an iSIM can’t be physically accessed, helping to reduce the risk of theft and tampering. iSIM can offer the same level of logical protection for the network credentials as a certified eSIM. Chip-level security is reinforced by a Secure Enclave. iSIM is fully compliant with GSMA Remote SIM Provisioning standards as well as ETSI SIM specifications.
What Is a secure enclave?
A Secure Enclave is a certified security module within a System-On-Chip design consisting of hardware and low-level software providing resistance against hardware and software attacks. It is capable of securely hosting Kigen SIM or eSIM OS together with applications and their confidential and cryptographic data.
It is also known as an integrated Tamper Resistant Element (iTRE).
