Changing SIM profiles over the air (OTA) has always been a dream for anyone operating in the Iot industry or leveraging Iot connectivity. Thanks to the new RSP (Remote SIM Provisioning) technology, it is now possible to switch M2M (machine to machine) eUICC profiles. 

But how is it possible? This article outlines the step-by-step process of switching eUICC profiles, providing context and highlighting the technology's transformative impact on the industry.

Understanding Remote SIM Provisioning (RSP)

Remote SIM Provisioning is a ground-breaking technology designed to enhance the capabilities and flexibility of SIM cards used in mobile devices and M2M applications. Traditionally, SIM cards have been physical entities that store subscriber information and authenticate users on mobile networks. RSP, however, introduces a shift by allowing the provisioning and management of SIM profiles over the air, eliminating the need for physical replacement or manual intervention.

eUICC and the RSP ecosystem

RSP utilizes the eUICC standard, where eUICC SIMs function similarly to conventional card-based SIMs. They can either be embedded in a device (MFF2) or placed into the SIM slot in removable formats (2FF, 3FF, 4FF).

From a software perspective, the key element of eUICC is the capability to allow users and devices to switch between different mobile network operators (MNOs) or subscription plans without the physical limitations of traditional SIM cards. The eUICC technology not only simplifies device design and logistics but also paves the way for enhanced user experiences and service offerings.

The RSP ecosystem requires a collaborative environment between device manufacturers, MNOs and RSP platform where the devices need to be engineered with eUICC capabilities both at a software and hardware level while MNOs need to integrate the RSP platform into their infrastructure, establishing a centralized hub for managing SIM profiles and facilitating secure communication for profile updates and management.

Key benefits of RSP

1. Mobile network choice - Remote SIM provisioning enables end users and businesses to seamlessly switch between SIM profiles offered by various mobile network operators without the need of physical replacement of SIM cards.

2. Compliance framework - In order to uphold security standards and regulatory compliance, the GSMA has established a comprehensive compliance framework applicable to all subscription management products, such as eSIM and eUICC. Adhering to this framework not only safeguards the integrity of your connectivity but also guarantees seamless interoperability across your devices.

3. Cost savings and operational efficiency - Substantial cost savings can be realized by both Mobile Network Operators (MNOs) and end users.  For MNOs by eliminating physical SIM cards and enabling remote troubleshooting while for end users, getting access to the best rates through local SIM profiles avoiding hefty roaming fees.

Switching eUICC profiles in 4 steps: 

There are a lot of complex processes that take place behind the scenes as we switch eUICC profiles - the great thing is that everything is streamlined into an easy to follow 4 step process:

1. Initiation

The process begins with the device or user initiating a request to switch profiles. This can be triggered by the user selecting a new profile through the device's interface or an M2M application signaling the need for a different profile to better suit its operational requirements.

2. Authentication and Security

Following the initiation, the RSP platform performs authentication and security checks. This requires verifying the device's identity and ensuring that the communication between the device and the RSP platform is encrypted to protect sensitive information.

3. Downloading the New Profile

Once authenticated, the new profile is downloaded to the SIM. The RSP platform ensures that the profile is correctly installed and configured, adjusting network settings and subscription details according to the new profile's specifications.

4. Activation and Confirmation

The final step requires activating the new profile and confirming its successful implementation. The device may then disconnect from the previous network and connect using the new profile's credentials, effectively completing the switch.
