Japan's First*, SGP.32-Compliant eIM (eSIM IoT Remote Manager) | Official Launch of eSIM Tech Partner "LibeSIM"

Common Creation Co., Ltd. (Headquarters: Fukuoka, Japan; CEO: Kazuki Muta; "Common Creation") today announced the official launch of "LibeSIM", an eSIM Tech Partner service providing the full eSIM stack of issuance, connectivity, management, and development, starting March 2, 2026.

* As the first Japan-based company to offer an SGP.32-compliant eIM (eSIM IoT Remote Manager), as of February 2026, based on Common Creation's research.

Background

With the rapid growth of IoT devices, the cost and lead time of distributing and managing physical SIM cards have become a major challenge for connectivity providers, system integrators, and device manufacturers.

Against this backdrop, the eIM (eSIM IoT Remote Manager) defined in "SGP.32", the GSMA specification for IoT eSIM, is attracting worldwide attention. Major SIM vendors and security companies around the world have begun commercial rollouts of SGP.32-compliant solutions, and 2026 is shaping up to be the year eSIM and SGP.32 reach mainstream adoption.

In Japan as well, demand for eSIM is expanding, particularly around Local 5G (Japan's licensing framework for private 5G networks), and the need to operate IoT devices through an eIM is rapidly becoming concrete. However, only a limited number of domestic providers can cover everything from eSIM issuance to remote management, and adopting eSIM has typically required combining multiple vendors.

LibeSIM solves these challenges as an "eSIM Tech Partner" that delivers the full stack of issuance, connectivity, management, and development from a single company, providing consistent technical support from PoC through commercial deployment.

Response to the early release

LibeSIM was first released in a preview form at the "Local 5G Summit 2025" held in December 2025. Since then, we have received a large number of PoC and adoption inquiries from connectivity providers, system integrators, and device vendors.

Going forward, based on feedback from the early release, we will continue to expand the management dashboard, strengthen API integration, and broaden the scope of eIM interoperability testing.

Service overview

LibeSIM addresses the main challenges of eSIM adoption through the following four services.

1. eIM (IoT remote management)

Japan's first SGP.32-compliant eIM, available as a commercial service*

Our GSMA SGP.32-compliant eIM (eSIM IoT Remote Manager) enables remote, centralized management of eSIM profiles on IoT devices. Profiles can be installed, enabled, and switched without any physical access to the device.

Common Creation is the first Japan-based company* to offer an SGP.32-compliant eIM as a commercial service. Drawing on the expertise gained through designing and developing our own eIM, we provide end-to-end technical support from PoC design to commercial rollout.

For customers considering eIM adoption, we also offer free demos and technical validation through PoC programs. Please feel free to contact us to see how the eIM works and whether it fits your environment.

Example use cases for eSIM / SGP.32

• Permanent roaming compliance for automotive and telematics devices For connected cars and in-vehicle telematics units, eSIM profiles can be switched remotely according to the country or region of operation, avoiding permanent roaming restrictions and optimizing connectivity without any on-site work.

• Flexible use of high-capacity data and voice lines Devices can run on a standard data profile and be switched remotely to high-capacity data or voice-capable profiles when needed, selecting the optimal plan for each use case and cost profile without touching the device.

• Switching between Local 5G (private networks) and public carrier networks In operations such as autonomous shuttle buses, devices can connect to a private Local 5G network inside factories, warehouses, or campuses, and switch automatically to a public carrier network outside. Centralized profile management through the eIM removes the operational complexity.

2. eSIM issuance platform (SM-DP+)

A cloud platform that issues and delivers eSIM profiles on demand. It can be deployed at a fraction of the initial cost of major SIM vendors, and supports anything from a single profile for PoC to thousands of profiles for commercial rollouts, with issuance in as little as one week. Multiple delivery methods are supported, including QR codes, email, and API integration, so the platform can be embedded flexibly into your own services.

The platform is carrier-independent and also supports private network environments such as Local 5G and sXGP. It is currently used in many projects, primarily by Local 5G customers.

It also works with iPhone and supports secure authentication with SUCI (Subscription Concealed Identifier), meeting the security requirements of the 5G era.

3. MVNO connectivity × SIM applet

A one-package service combining our own MVNO connectivity with SIM applets. Because the line subscription and applet capabilities are integrated, no additional vendor integration is required.

By combining SIM applets, we deliver value-added services such as location tracking without GPS, device authentication, and secure storage.

Since these capabilities are implemented on the eSIM itself, no hardware modification of the IoT device is required. Existing devices can be used as they are while new connectivity-driven services are rolled out.

Example use cases for SIM applets

• Asset tracking of rental equipment (printers, construction machinery, etc.) using SIM-based location

• Travel SIMs for tourism solutions with embedded SIM applets

• Device authentication and management capabilities for IoT devices

4. R&D and technical support

Alongside the three services above, we provide R&D and technical support covering the full range of eSIM-related technologies.

Our engineering team combines system design capabilities built through software development with deep telecom expertise, covering SIM applet development, API design and system integration, eUICC (embedded SIM chip) procurement support, and eIM adoption support, and designs the optimal eSIM environment for each customer's requirements.

Why LibeSIM

Full-stack delivery

eSIM issuance (SM-DP+), MVNO connectivity, SIM applets, and an SGP.32-compliant eIM, all from a single company. This eliminates the integration cost and unclear demarcation of responsibility that come with multi-vendor setups.

Strong cost advantage

By building the entire ecosystem in-house, our initial cost is approximately one-tenth that of major SIM vendors, enabling small-scale validation before scaling.

Fast issuance, small lots

eSIM issuance that takes weeks to months with major vendors is available in as little as one week, starting from a single profile for PoC.

End-to-end support from PoC to commercial rollout

We work alongside our customers as a technical partner from the validation stage, addressing every technical challenge related to eSIM.

Comment from the Head of LibeSIM

Masaki Yamamoto, Head of LibeSIM, Common Creation Co., Ltd.

eSIM technology is evolving rapidly, but in Japan, issuance, connectivity, and management are still handled by separate vendors, and the barrier to adoption remains high. Even at the PoC stage, companies often need to contract and coordinate with multiple vendors individually, and it is not unusual to spend months before validation can even begin.

With LibeSIM, we have built an environment where customers can quickly validate the value of eSIM and move on to commercial deployment, by providing the full stack from eSIM issuance to connectivity and eIM (IoT remote management). For the SGP.32-compliant eIM in particular, where technical information is still scarce in Japan, we have built a structure that allows us to offer it as a commercial service ahead of others.

We see 2026 as the turning point when eSIM, and SGP.32 in particular, reaches full-scale adoption. As an "eSIM Tech Partner", we will support connectivity providers and IoT device manufacturers on the technical front and contribute to the growth of the eSIM ecosystem in Japan.

Future outlook

Through LibeSIM, we will continue to open up eSIM technology and support adoption by a wide range of customers, from connectivity providers to IoT device manufacturers.

Specifically, we are planning the following initiatives.

Expansion of the partner program

We offer three collaboration models for putting LibeSIM's technology and services to work, namely a reseller and distributor model, white-label provision, and technology partnerships.

Expansion of use cases

In addition to Local 5G and IoT device management, we will expand into new use cases such as large-volume distribution for events and entertainment, disaster preparedness for local governments, and tourism solutions.

Use of an IIN (Issuer Identification Number)

Common Creation has been allocated an IIN (Issuer Identification Number) by the International Telecommunication Union (ITU), and we are building a structure that allows us to complete the entire eSIM issuance value chain in-house, including automatic ICCID numbering.
