    About SIM lock:

    A locked handset will display a message if a restricted SIM is used, requesting the unlock code. On recent phone models running Android software, the phone will display a message saying ¡°SIM network unlock PIN¡± or ¡°Enter Network Lock Control Key¡± if network locked. Windows phones will display the message, ¡°This SIM card can only be used on specific networks. Contact your customer service center for the unlock code¡±. Other handsets may display different messages such as "Enter special code" or "Enter unlocking code," or in some cases the handset will simply display a message stating that it is locked. Once a valid code is entered, the handset will display "Network unlocked¡± or ¡°Network unlock successful¡±.

    The unlock code is verified by the handset and is generated by the network provider, typically by an algorithm such as a one way hash or trapdoor function. The algorithms used in many handsets are based on the IMEI number and the MCC code and have been reverse-engineered, stolen or leaked.
