AI Technical Summary
Current mobile phones cannot effectively isolate and manage SMS services from multiple SIM cards, resulting in users' inability to meet their personalized needs in different scenarios and posing a risk of privacy data leakage.
By introducing a subsystem-SIM card association mechanism into electronic devices, isolated management of SIM cards is achieved. SMS information is hidden when the subsystem is not activated, and relevant information is only displayed in the subsystem to prevent privacy leaks. The security of SMS records is ensured through interface design and storage location isolation.
It enables isolated management of SIM cards in different scenarios, protecting user privacy, simplifying SMS management, and improving user experience and security.
