Remote eSIM Provisioning Using Confirmation Code Relay
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 confirmation codes or facing difficulties in locating them.
Innovation Solution
A system and method for remote SIM provisioning with a confirmation code, allowing users to request or automatically receive the code when activating a device, enabling seamless activation through a network of platforms and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional eSIM activation protocols are used, then device activation can be completed, but user interaction complexity increases and scalability decreases
Solution Approach 1:
The system pre-generates and stores confirmation codes in a database before activation is needed. When activation occurs, the pre-prepared code is retrieved and presented to the user, eliminating the need for real-time code generation and reducing user interaction complexity while maintaining scalability
2Reliability
If confirmation codes are sent to users during activation, then activation security is improved, but users may misplace or lose access to the codes
Solution Approach 1:
The system introduces an intermediary interface (user interface on the UE device) that mediates between the secure code storage and the user. The interface displays the confirmation code directly to the user during activation, ensuring secure delivery while maintaining easy accessibility. The intermediary also provides fallback mechanisms like resending codes if users lose access
Solution Approach 2:
The system enables users to request re-sending of confirmation codes through the user interface without requiring customer service intervention. This self-service capability ensures users can recover lost codes independently, maintaining both security and accessibility
3Ease of operation
If manual confirmation code processes are used, then individual device activation works, but bulk activation efficiency decreases
Solution Approach 1:
Confirmation codes are pre-generated and stored in the database before bulk activation events. When multiple devices need activation, the system retrieves pre-prepared codes efficiently, enabling parallel processing and significantly reducing the time required for bulk activations compared to real-time code generation
Solution Approach 2:
The system uses template-based confirmation code structures that can be rapidly instantiated and customized for different devices. Instead of creating entirely new activation protocols for each device, the system copies and adapts proven activation templates, maintaining consistency while improving processing speed

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. 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 first confirmation code to a second user device. Methods and systems may receive, by the SM platform over the second network, a second confirmation code provided by a user, and send the SIM profile associated with the device ID.
