eSIM Profile Transfer via Call Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with embedded subscriber identity modules (eSIMs) are sold with fixed SIM profiles, making it impossible to transfer eSIM cards between devices or change telecommunication operators, limiting user flexibility in managing their communication services.
Innovation Solution
An electronic device and method that identifies and transmits eSIM profile information for call forwarding, allowing users to set up and manage eSIM profiles on external devices, enabling the transfer of eSIM cards and operator changes through call forwarding requests and profile management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a wearable device is sold with a fixed SIM profile during manufacturing, then the device can be produced and sold immediately, but it becomes impossible to transfer the eSIM card between devices or change telecommunication operators
Solution Approach 1:
The patent segments the SIM functionality into a separable eSIM card that can be independently transferred between devices. The wearable device and external electronic device can share the same eSIM card through call forwarding, allowing the SIM profile to be decoupled from any single device while maintaining manufacturing simplicity.
Solution Approach 2:
The eSIM card is designed to be universally compatible across multiple devices and telecommunication operators. By enabling call forwarding between wearable and external devices, the same eSIM card can serve multiple functions and be used with different operators, enhancing adaptability without complicating the manufacturing process.
2Adaptability or versatility
If eSIM profile information is transmitted and managed between devices, then user flexibility and adaptability are improved, but the device complexity and communication overhead increase
Solution Approach 1:
The patent introduces call forwarding as an intermediary mechanism that simplifies eSIM profile management. Instead of directly transmitting complex profile data between devices, the system uses call forwarding requests and responses as a mediator to enable seamless eSIM card transfer and operator changes, reducing the perceived complexity for users.
Solution Approach 2:
The system creates a virtual copy of the eSIM card functionality across multiple devices through call forwarding. When call forwarding is enabled, the external electronic device receives a copy of the call forwarding information, allowing the same eSIM profile to be accessed from multiple devices without physically transferring the eSIM card or increasing hardware complexity.

AI summary
An electronic device is provided. The electronic device includes a memory, a communication module configured to communicate with an external electronic device, and a processor configured to: when a call forwarding is requested by the external electronic device, identify information on an embedded subscriber identity module (eSIM) profile of the external electronic device, based on call forwarding-related information stored in the memory; transmit the information on the eSIM profile to the external electronic device via the communication module; and set up the call forwarding with the external electronic device using the eSIM profile based on the information on the eSIM profile.
