Everything eSIM requires. Nothing locked in.
eSIM Tech Partner「LibeSIM」
From line issuance and SIM applet development to IoT device management, we provide every technology eSIM requires, one-stop.
We design the configuration that best fits your requirements and, as your technical partner, support you all the way from PoC to commercial rollout.
Facing these challenges
in eSIM adoption and operations?
High costs and long lead times for eSIM issuance
Initial costs run into the millions of yen and issuance takes weeks, so for smaller operators, or for projects still at the PoC stage, the economics simply do not add up.
Adding IoT capabilities requires engaging multiple vendors
Adding capabilities to an IoT device requires hardware modification, and with the vendors involved scattered across the chain, adoption costs and coordination effort keep piling up.
Managing eSIMs across a large IoT fleet is difficult
Managing hundreds to tens of thousands of devices individually has clear limits, and in Japan there are still almost no services that support SGP.32.
LibeSIM solves all of these challenges as your one-stop partner.
SM-DP+ (eSIM issuance and management)
The platform is carrier-independent and supports private network environments such as Local 5G (Japan's licensing framework for private 5G networks) and sXGP. It also works with iPhone and supports SUCI (Subscription Concealed Identifier), meeting the security expectations of 5G deployments.
MVNO connectivity × SIM applet
SIM applets let you integrate value-added features, such as GPS-free location tracking and device management, into IoT equipment without modifying the hardware.
eIM (IoT remote management)
Our GSMA SGP.32-compliant eIM (eSIM IoT Remote Manager) manages eSIM profiles across your IoT fleet remotely and in bulk. Profiles can be installed, enabled and switched without physical access to the device. As one of the few partners in Japan able to offer an SGP.32-compliant eIM, we provide technical support from PoC design through commercial rollout.
R&D and technical support
We cover the full breadth of eSIM-related technology: SIM applet development, API design and system integration, eUICC procurement, and eIM adoption support. An engineering team that combines the system design capability built through software development with specialist telecom knowledge designs the eSIM environment best suited to your requirements.
LibeSIM eUICC (SGP.32 compliant)
An open eUICC, faithful to the standards, that ties you to neither a carrier nor an eIM. LibeSIM eUICC supports both SGP.22 (Consumer) and SGP.32 (IoT), and can be combined with any connectivity and any eIM, free of lock-in to any single provider.

A technical partner supporting everything from eSIM issuance to operations, one-stop
LibeSIM provides its own MVNO connectivity while also delivering the eSIM issuance platform (SM-DP+), SIM applet technology and an SGP.32-compliant eIM as a full stack. Unlike providers that offer only connectivity or only a platform, this eliminates the integration costs and blurred lines of responsibility that come with multi-vendor setups.
Initial cost
approx. 1/10 of major vendors
By building the ecosystem in-house, we cut costs substantially compared with major SIM vendors. Return on investment becomes easier to project, and a small start becomes realistic.
Issuance lead time
as little as one week
eSIM issuance that takes weeks to months with major vendors is handled in as little as same-day to one week. From a single profile for a PoC to thousands for commercial rollout, we scale flexibly to the use case.
PoC to commercial rollout
as fast as 2 to 3 months
Issuance itself is same-day, and the full process from validation to commercial launch runs in 2 to 3 months. A dedicated engineering team stays with you from PoC design through commercial rollout.

MVNO connectivity × SIM applet
Push notification-based information delivery for inbound tourism, combining SIM applet location tracking with LINE integration.
Example projects built with eSIM
Representative projects built with eSIM and eIM, from Local 5G to events, entertainment and tourism.
Local 5G × education
Provide students and researchers with instant access to a campus Local 5G network via QR code. Connectivity rolls out with the ease of free Wi-Fi, with no physical SIMs to distribute or collect.
Fleet-wide IoT device management
Distribute eSIMs remotely and in bulk to thousands of IoT devices and beyond. With an SGP.32 eIM, profiles are switched and updated without on-site SIM swap work.
Asset tracking for rental equipment
Fit printers, construction machinery and similar assets with eSIMs and detect removal or non-return through GPS-free, SIM-based location. Position stays available inside tunnels and warehouses, as long as the device is within network coverage.
Events and entertainment
Distribute high-speed connectivity for video streaming to attendees' phones, bundled with the ticket. With campaign-style delivery, a single QR code provisions thousands of people at once, with no per-person distribution work.
Tourism solutions
Load a travel SIM with a SIM applet to deliver area-specific tourism information via push notifications while capturing visitor movement data at the same time. A 1 to 2 GB eSIM is distributed easily by QR code.
Local government and disaster preparedness
Distribute safety-confirmation lines instantly through QR codes in LINE or public bulletins. No physical SIM stockpiles to maintain or manage, with the exact number of lines issued on demand, whenever needed.
