The SIM lock mechanism is generally managed by the Modem’s file system. When a non-authorized SIM card is inserted, the modem queries the user for an unlock code (often termed NCK - Network Control Key). The modem compares the user input against a stored hash or derives the expected code dynamically based on the device's International Mobile Equipment Identity (IMEI).

Historically, Huawei utilized specific algorithms to generate these codes. In older security versions, the NCK was static and stored in the modem's NVRAM (Non-Volatile RAM). However, modern security protocols often derive these codes dynamically or require server-side authentication.
