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 create 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 – Five Key Drivers
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 organisations 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.”
Stacuity and Kigen teams look forward to jointly discussing this collaboration at MWC 2026 in Barcelona with MVNOs, MNOs, and enterprises looking to serve global demand for eSIMs.
