Mitigation
Do you have a problem like this?
IoT device designers
- The number of product variations increases with each carrier.
- Designing with future changes in telecommunications carriers and plans in mind is difficult.
- The product has a long lifespan, but there are concerns about changes in the communication environment and contracts.
- We want to reduce the burden of on-site SIM card replacement and maintenance support.
Service planning manager,
Operations staff
- We want to consider communication methods that will allow us to expand overseas.
- We want to optimize future communication costs.
- We want to minimize the risks associated with communication failures.
- I want to be able to flexibly change my communication contract as the services expand.
In the long-term operation of IoT services,
It is important to be prepared for changes in the communication environment.
If the SIM card embedded in an IoT device could be rewritten remotely after the device has been shipped, without having to go to the site,
Could these challenges be solved?
To achieve that,
Remote provisioning
That's the technology.
What is remote provisioning?
This system allows you to remotely rewrite the communication profile (carrier information) without physically replacing the SIM card. Traditionally, one SIM card was fixed to one carrier and communication plan, but this technology allows you to choose and change carriers and communication plans later using a single SIM card.
The industry standard "SGP.32" that supports the system
SGP.32 is a specification for enabling remote provisioning in IoT devices. It is a next-generation eSIM standard for IoT devices developed by the GSMA. Because it is not a proprietary system specific to any particular manufacturer, it is common across the industry and can be adopted with confidence.
Connect SIM by macnica provides SIM cards that comply with SGP.32.
Why are IoT devices "SGP.32 compliant"?
Is it necessary?
eSIMs for smartphones (SGP.22) are designed with the assumption that users will switch between them via the screen. However, this method cannot be used in IoT devices that do not have screens. SGP.32 is a standard designed for IoT devices that allows for remote and automatic profile management without the need for a screen or user interaction.
Remote provisioning
Four things to achieve
Carrier switching
This will make it easier to flexibly adapt to future changes in telecommunications carriers and plans.
Global Operations
This makes it easier to consider how to address different communication environments in each country and region.
Remote operation
Manage communication profiles from the dashboard to achieve flexible communication operations.
Long-term operation of equipment
Even IoT devices with long product lifecycles can be operated with future changes in mind.

With "Connect SIM",
Realizing a flexible IoT communication environment
Connect SIM by macnica is a communication service for industrial IoT. Based on NTT Docomo lines and multi-carrier SIMs, we offer flexible plans tailored to your needs and support everything from the introduction to the operation of IoT devices.
Optimizing communication costs
Industrial IoT devices have diverse applications, including devices with fluctuating data usage, devices primarily focused on uplink communication, and devices that utilize large data capacities. Connect SIM offers customized plans tailored to your usage, including two-tiered plans, shared plans, and uplink-focused plans. Flexible communication plans enable cost optimization.
NTT Docomo network + multi-carrier support ensures stable operation both domestically and internationally.
Based on NTT Docomo's network, we offer multi-carrier SIMs compatible with all three major Japanese carriers. In addition to providing backup lines during communication failures and optimizing coverage, it also supports communication for overseas devices. This ensures network redundancy and contributes to improved business continuity planning (BCP).
Both physical SIMs and chip SIMs can be provided to suit your device.
In addition to standard card SIMs, we also support board-mounted chip SIMs (MFF2). We provide optimal SIMs for industrial equipment requiring environmental resistance from -40 to +105°C, as well as miniaturization and tamper resistance. As a semiconductor trading company, we will provide support.
SGP.32 compliant remote provisioning-enabled eSIM
We also offer SGP.32 compliant SIMs that allow you to remotely rewrite carriers and profiles even after shipment. This allows us to support long-term product operation, SKU standardization, carrier changes, and preparation for overseas expansion.
"Connect SIM" plans
Here is an example of a plan.
We will propose the optimal plan tailored to your needs and operational requirements. Please feel free to contact us if you are unsure.
Upbound Main Plan
Designed for IoT devices where uplink communication is the primary mode of transport.
This plan is suitable for applications that involve sending data from sensors and devices to the cloud.
- equipment monitoring
- Sensor data collection
- Meter monitoring
- Remote monitoring
Share plan
Operate multiple lines efficiently by consolidating them.
This plan is suitable for those who want to efficiently utilize their data allowance in a multi-SIM environment.
- Mass deployment of IoT devices
- Multiple location deployment
- Fleet Management
- Nationwide service
Two-stage plan
Suitable for devices with fluctuating data usage.
This plan allows you to set fees based on usage and is frequently adopted for industrial IoT applications.
- equipment monitoring
- Remote maintenance
- Devices that only communicate in abnormal situations.
- Equipment with seasonal variations
Use Case
Surveillance cameras and remote monitoring systems
Reducing maintenance costs after installation and ensuring stable operation are important.
High availability to prevent communication interruptions and remote management are required.
Task
- If the installation location is at a high altitude, in a mountainous area, or at a construction site, on-site dispatch and work are required each time the SIM card is replaced, resulting in enormous labor costs per unit.
- In some cases, after installation, it may be discovered that the SIM card's carrier cannot connect, requiring a physical replacement of the SIM card.
- There is a risk that security and safety equipment will cease to function during communication failures.
suggestion
- It uses a SGP.32 compliant SIM and enables remote rewriting of carrier profiles.
- In addition to the main line, a backup profile is prepared in advance. The system is configured to automatically switch over in the event of a failure, ensuring redundancy.
merit
- Reduced on-site work: Carrier and plan changes can be handled remotely, reducing travel and operational costs.
- Addresses area coverage issues after installation: You can switch carriers later depending on the radio wave conditions.
- Avoids data loss: Allows switching to a backup line in the event of a failure. Also functions as a BCP (Business Continuity Plan) measure.
Construction machinery, agricultural machinery, industrial IoT devices
- Globally standardized design and unified SKUs directly lead to operational efficiency.
- Ensuring a stable communication environment in each country is required.
Task
- It is necessary to contract with local carriers for each destination and procure, stock, and install SIM cards.
- By separating SKUs by country and carrier, the number of BOMs, inventory, and maintenance costs increase.
- Due to permanent roaming restrictions, some countries will cut off communications after a certain period of time.
- For equipment requiring long-term operation, a mechanism is needed to adapt to changes in the local environment after shipment.
suggestion
- It uses a SGP.32 compliant SIM. It ships with a common bootstrap (initial profile) and switches to the destination profile remotely after arrival at the destination.
- The configuration involves managing with a single SKU and changing communication differences using profiles.
- In countries with permanent roaming restrictions, remote distribution of local carrier profiles enables compliant operations.
merit
- SKUs can be standardized: eliminating the need for destination-specific inventory management. Design, procurement, and maintenance costs can be reduced.
- Compliant with roaming restrictions: Remote switching of local profiles ensures continuous communication even in restricted countries.
- Durable for long-term operation: Even if local conditions or carrier circumstances change after shipment, remote support is possible.
