Simplifying IoT Connectivity: Kigen eSIM and Stacuity’s Multi-IMSI

Organizations can combine Kigen’s SGP.32 eSIM capability and Stacuity’s multi-IMSI core platform to deliver IoT connectivity with global reach, robust local behaviour, operational simplicity, and commercial sustainability over long device lifecycles.

As IoT deployments move from regional pilots to global scale, connectivity becomes less about coverage and more about control. Enterprises and service providers require the ability to deploy once, operate globally, and adapt over time, without having to redesign devices or rebuild infrastructure.

By combining Kigen’s SGP.32 eSIM capability with Stacuity’s multi-IMSI core platform, organizations can deliver global IoT connectivity that is flexible by design, operationally simple, and commercially sustainable over long device lifecycles.

A Practical Foundation for Global IoT

SGP.32 represents an important step forward for IoT connectivity. Designed specifically for large-scale deployments, it allows connectivity profiles to be provisioned and managed remotely in a standardised way, removing much of the operational overhead traditionally associated with global rollouts.

Kigen’s SGP.32-enabled eSIM technology gives enterprises the confidence that devices can be deployed anywhere and adapted later, whether that means changing operators, entering new markets, or responding to evolving regulatory requirements.

Complementing this flexibility, Stacuity’s multi-IMSI software-defined core introduces a single control layer that persists throughout the device lifecycle. While IMSIs or underlying providers may change, the policies governing traffic routing, local breakout, cross-connect selection, operator steering, and security are defined and managed at the endpoint level and updated dynamically. This ensures consistent behaviour independent of the active IMSI and allows multiple IMSI ranges to operate within a single logical core, without duplicating infrastructure.

By enabling multiple IMSIs on a single eSIM, devices can attach as local subscribers where required, improving performance, eliminating issues in devices with UX or requiring user consent for needed profile swaps and supporting regulatory requirements. All whilst avoiding the long-term limitations of permanent roaming models or the operational complexity typically associated with multi-operator environments.

Together, Stacuity and Kigen creates a connectivity approach that combines global reach with local behaviour.

“SGP.32 unlocks simpler, standards-based control of global IoT at scale. By combining Stacuity’s multi-IMSI core with security assurances of our SAS-certified Kigen eIM for SGP.32, supported by Kigen eSIM OS, we enable smoother fleet transitions, compliance to regulations, and operational stability,” said Jean-Louis Carrara, Head of Global Sales at Kigen. “A leap forward to the world of no truck rolls: so organizations can enter new markets over time with the confidence needed for mission-critical deployments.”

The Strategic Significance – 5 Key Drivers

Deploy globally, operate locally

Devices can be shipped with a single hardware configuration and activated anywhere in the world. Connectivity can then be optimised locally through multi-IMSI capability, improving network performance and user experience without operational complexity. Stacuity’s single logical core architecture accelerates the onboarding of new IMSI ranges, reducing time-to-market and operational overhead.

Resilience built into the connectivity layer

Multiple IMSIs allow devices to move between networks automatically when coverage or quality changes. Combined with profile management via the Kigen eSIM remote IoT manager, Kigen eIM, which has achieved GSMA Security Assurance Scheme (SAS) certification, it provides continuity of connectivity. Augmented by secure Kigen eSIM OS Rescue and recovery logic, this can provide a strengthened foundation for more expedient switchovers for mission-critical IoT deployments.

Commercial flexibility over the device lifecycle

IoT deployments often last years, and sometimes decades. The combination of SGP.32 profile orchestration and a multi-IMSI core allows connectivity strategies to evolve over time, reducing dependency on single operators and enabling better long-term cost control. Per-IMSI commercial models can coexist within one platform, enabling differentiated pricing, SLAs, or regulatory models without infrastructure duplication.

Simplified global operations

Operators and enterprises can reduce their number of SKUs, streamline provisioning processes, and launch new services faster. Connectivity becomes something you can control, rather than a fixed constraint.

With integrated diagnostics, packet inspection, signalling visibility, and remote device access built directly into the platform, Stacuity also reduces reliance on external tooling, simplifying troubleshooting and ongoing fleet management.

Alignment with industry standards

Both Kigen and Stacuity operate within GSMA frameworks, ensuring interoperability and long-term compatibility as networks evolve.

Enabling the Next Phase of IoT Growth

For enterprises and connectivity providers looking to scale globally, the challenge is no longer simply about connecting devices, it is maintaining flexibility as markets, regulations, and commercial models change.

By combining Kigen’s SGP.32 eSIM technology with Stacuity’s multi-IMSI core, organisations gain a connectivity foundation that can adapt as deployments grow.

Both organizations bring together ecosystems that offer unparalleled choice in the tools needed to seamlessly orchestrate complex global eSIM solutions. Devices can be deployed once, managed centrally, and optimised continuously, creating a more resilient and future-proof approach to global IoT connectivity.

“Stacuity’s software-defined platforms are built to enable and complement all players across the connectivity ecosystem, supporting customers in delivering true best-of-breed solutions,” said Roberta Castle, Founder and CRO at Stacuity. “The combination of Kigen’s SGP.32 eSIM capabilities and Stacuity’s multi-IMSI core demonstrates how complementary technologies can come together to create differentiated, flexible, and commercially sustainable solutions for both suppliers and end customers.”
