Multi-IMSI vs. eUICC

When it comes to IoT, there are two main options for multi-network SIMs: Multi-IMSI and eUICC. Since IoT devices are often placed in remote locations, used for complex purposes, and left unattended for many years, it’s crucial that their connectivity requirements are comprehensive and forward-looking.

Multi-IMSI technology enables a single SIM card to store multiple IMSIs, which are unique identifiers for mobile subscribers. With a multi-IMSI SIM, a device can connect to multiple mobile networks, even if they are from different MNOs. This technology is particularly useful for IoT devices that require the ability to switch between different networks or to roam between networks in case the primary one is unavailable.

The eUICC, or Embedded Universal Integrated Circuit Card, is a new type of SIM card that can be provisioned and managed remotely. This means that SIM profiles can be easily added, removed, and updated over the air without requiring physical access to the SIM card. This can be particularly advantageous for IoT devices that are deployed in remote locations or used for complex use cases.

This white paper by FloLIVE compares multi-IMSI and eUICC technologies and advocates for a combined approach:

1. Multi-IMSI Solutions For IoT Use Cases: The pros (Flexibility, cost-effectiveness, ease of deployment) and cons (Complexity, security, compatibility ) of this approach are analyzed.
2. The Rise of eUICC: This new type of SIM resolves many challenges, yet enterprises hesitate to adopt it widely. The paper discusses the possible reasons (Costs and complexity).
3. Why should multi-IMSI and eUICC together be the next big thing? The combination of multi-IMSI and eUICC can offer several benefits for IoT enterprises, including:

• Reduced costs: Enterprises can save money on SIM card costs and provisioning fees by using multi-IMSI SIMs, which reduce the number of SIMs they need to manage.
• Increased flexibility: Enterprises can now choose the best network using multi-IMSI SIMs connecting to multiple networks.
• Improved security: eUICC SIMs are more secure than traditional SIMs, which can help to protect against unauthorized access to IoT devices.
• Simplified management: eUICC SIMs can be remotely provisioned and managed, saving time and money for enterprises.

As a result, the combination of multi-IMSI and eUICC is well-positioned to be the next big thing in IoT connectivity.
