Remote eSIM Provisioning Using Confirmation Code Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM technology for UE devices requires high user interaction and lacks scalability in initial connectivity processes, particularly in bulk activations, with users often misplacing or failing to find confirmation codes for device activation.
Innovation Solution
A system and method for remote SIM provisioning that allows users to request or automatically send confirmation codes from a provisioning system, enabling seamless activation of eSIM-enabled devices by integrating a local profile assistant and utilizing a remote SIM provisioning platform to manage ICCID reservations and confirmations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eSIM protocols are used for device activation, then security level is improved and device compatibility is enhanced, but user interaction complexity increases and scalability is reduced
Solution Approach 1:
The system enables self-service activation by allowing users to autonomously retrieve confirmation codes through their existing account credentials or alternative verification methods. The provisioning system automatically sends confirmation codes to registered devices or emails, eliminating the need for manual assistance while maintaining security protocols. This resolves the contradiction by making the secure eSIM activation process self-serving rather than requiring complex user interactions with support staff.
Solution Approach 2:
The confirmation code acts as an intermediary element between the user and the eSIM provisioning system. Instead of requiring direct complex interactions for security verification, the system introduces a simple confirmation code as a mediator that users can easily obtain and input. This intermediary simplifies the user experience while maintaining the security requirements of eSIM protocols.
2Reliability
If manual confirmation code retrieval is required, then security verification is maintained, but activation time increases and user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-registering user contact information and device identifiers before the activation process. When activation is needed, the confirmation code is automatically sent to pre-configured channels (email, SMS, or registered devices) without requiring users to search through multiple applications or contact support. This preliminary setup reduces activation time while maintaining security verification through the pre-established communication channels.
Solution Approach 2:
The system implements feedback mechanisms by automatically notifying users when confirmation codes are sent and providing real-time status updates on the activation process. This feedback loop reduces uncertainty and allows users to quickly understand the activation status without repeated inquiries, thereby reducing overall activation time while maintaining proper security verification through the confirmation code requirement.
3Reliability
If confirmation codes are sent through multiple channels, then reliability of code delivery is improved, but system complexity and resource consumption increase
Solution Approach 1:
The system applies local quality by sending confirmation codes through different channels based on user preferences and device context. Instead of uniformly using all available channels for every user, the system selectively chooses the most appropriate channel for each user's situation (e.g., email for desktop users, SMS for mobile users, push notifications for app users). This reduces system complexity by avoiding unnecessary multi-channel operations while maintaining high delivery reliability through context-aware channel selection.

AI summary
A system and method disclosed provide a subscription management (SM) platform, associated with a mobile network operator (MNO), that may receive from a first user device, over a second network other than the MNO, a discovery message including the device identifier. The first user device may not include a SIM profile activated to provision the MNO. Methods and systems may send, by the SM platform to the first user device over the second network, a confirmation code request message and receive a confirmation code response message indicative of a request to send a stored confirmation code to a second user device. Methods and systems may receive, by the SM platform over the second network, a confirmation code entered by a user, and send the SIM profile associated with the device ID to activate for provisioning the MNO.
