SUBSCRIBER IDENTITY MODULE SELF-INVALIDATION

原文（中文）

Embodiments of the present disclosure are directed to systems and methods for self-invalidation of a subscriber identity module (SIM) in a mobile communication device. This mechanism allows the SIM to invalidate itself after detecting a predetermined number of consecutive incorrect authentication attempts, preventing unnecessary attempts to access a network. The system's operations include initiating an authentication session, receiving an authentication request from the network, and verifying the received authentication values against pre-stored values. If incorrect values are detected consecutively, the SIM increments a counter. Once the counter reaches a pre-configured threshold, the SIM updates the international mobile subscriber identity (IMSI) to a null value, rendering the SIM invalid for further use.
