eSIM Profile Installation Compatibility Checks to Prevent Network Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network lock occurs when an invalid embedded subscriber identity module (eSIM) card is inserted into an electronic device, preventing network-related functions, as the eSIM cannot be physically removed, unlike a plastic SIM card.
Innovation Solution
A method is implemented to prevent network lock by checking network operator-related information before downloading an eSIM profile, using a lock setting unit to compare extracted identification information with stored lock setting information to determine if network lock will occur, and either stopping the download or displaying a warning if it will.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an eSIM profile is downloaded and installed in the electronic device, then network communication function is enabled, but network lock occurs when the eSIM is incompatible with the device's network settings
Solution Approach 1:
The patent applies preliminary action by checking network operator compatibility information before downloading the eSIM profile. The processor extracts network operator information from the eSIM profile data received from the server, compares it with the device's network settings (MCC/MNC), and determines compatibility in advance. This prevents network lock from occurring before the eSIM is fully installed, resolving the contradiction by enabling reliable network communication only when compatibility is confirmed beforehand.
2Object-affected harmful factors
If network lock prevention checking is performed before eSIM profile download, then network lock is prevented, but additional processing time and complexity are required
Solution Approach 1:
The patent applies self-service by implementing automated network operator information extraction and compatibility checking. The processor automatically extracts MCC/MNC information from the eSIM profile data, compares it with stored network settings, and determines compatibility without requiring manual user intervention or complex external verification systems. This automation prevents network lock while minimizing added complexity, as the device performs the checking using its own existing resources and data.
