Common Creation Inc. (Headquarters: Fukuoka City, Fukuoka Prefecture; CEO: Kazuki Muta; hereinafter 'the Company') has unveiled an implementation demo of automatic network switching that combines the SGP.32-compliant eIM (eSIM IoT Remote Manager) of the eSIM Tech Partner 'LibeSIM' with GNSS (location information).
This implementation is structured as a Proof of Concept (PoC) for a mechanism that remotely and automatically activates the corresponding network profile from the eIM, triggered by an IoT device entering an area pre-defined on a map. Details of the demo can be viewed at the Company's booth at 'Wireless Japan 2026,' held at Tokyo Big Sight from Wednesday, May 27 to Friday, May 29, 2026.
Background
In field operations involving mobile IoT devices such as vehicles, buses, construction machinery, and logistics devices, there is an emerging need for area-dependent connectivity management. This includes situations where the optimal communication carrier differs by area, or where there is a desire to use a local network only within specific facilities. On the other hand, the operational practices of physically swapping SIM cards on-site or entering into separate network contracts for each device are unlikely to be realistic options for large-scale IoT deployments, as operational loads and costs increase alongside the number of devices.
The Company officially launched the eSIM Tech Partner 'LibeSIM' service in March 2026, becoming the first domestic company* to provide a service featuring a GSMA SGP.31/32-compliant eIM (eSIM IoT Remote Manager). eIM is a next-generation standard technology that enables centralized execution of remote installation, activation, switching, and deletion of eSIM profiles without the need to physically access the device.
This demo is implemented as a PoC for a mechanism that automatically switches to the network suited for the area, using GNSS location information as a trigger, based on this eIM remote profile switching functionality.
* As of February 2026, as a domestic company providing a GSMA SGP.32-compliant eIM (eSIM IoT Remote Manager). (According to the Company's research)
Overview of the Demo
This demo is an implementation that remotely and automatically activates the corresponding network profile from the eIM, triggered by an IoT device entering an area pre-defined on a map.
Operators only need to draw an area on the map and assign it the same name as the network profile managed on the eIM. This makes it possible to automate network operations for each area without requiring physical manipulation of the device or individual remote instructions. The operational scenarios envisioned by this implementation are as follows:
Automatic switching of regional carriers in wide-area moving vehicles
Automatically switching to the optimal local carrier's network profile for the area upon crossing prefectural borders. In applications such as bus location systems, optimizing the network used for each operational area.
Automatic switching between Local 5G / Public Networks inside and outside facilities
Activating enterprise network profiles, including low-latency Local 5G, upon entering port and airport areas. Enabling connection to private networks only when logistics tracking vehicles enter a facility.
Automatic switching in temporary areas
Realizing operations that switch networks simply upon arrival at the site, without requiring configuration changes on the device side, even in areas generated for a limited time such as construction sites and event venues.
Configuration of the PoC Implementation
This PoC conducted operational verification using the following configuration, assuming an in-vehicle router.
Item
Details
Verification Vehicle
Verification vehicle (equipped with an IoT device with a GNSS receiver)
Area Definition
Two areas, 'Kawagoe' and 'Saitama' within Saitama Prefecture, defined as polygons on a map
Network Profiles
Two profiles prepared for each area
eUICC
Embedded eUICC compatible with SGP.32
Switching Trigger
Area entry determination based on GNSS location information
Network Switching by eIM (Geofence Setting Example)
In the verification, it was confirmed that the communication of the in-vehicle device automatically switches according to the defined area as the verification vehicle moved from the Kawagoe area to the Saitama City area.
Details of this implementation and a demo video are published in the LibeSIM technical blog article, '[SGP.32 eIM Use Case] Network Switching by eIM Based on GNSS Location Information.'
Overview of the Switching Flow
In this implementation, the series of processes from area definition to network switching is realized through the following flow.
Area Definition
On the map of the management screen, draw the area where you want to switch networks in a polygon format.
