SIM lock:

A SIM-LOCK, Network Lock, Carrier-Lock, IMEI LOCK or (MASTER) subsidy lock is a technical limit built into CDMA and GSM mobile devices by manufacturers for use by carrier networks to limit using these phones to specific locations and/or networks. This is contrary to a mobile phone (retrospectively called SIM-free or unlocked) that doesn't impose any SIM constraints.

Typically, a locked smartphone will display a message if a restricted SIM is used, requesting the unlock code. On new phone models working on Android operating system software, the smartphone will display a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is 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”. Some other handsets may possibly show different messages which include "Enter special code" or "Enter unlocking code," or in some instances the device may simply display a message stating that it is locked. Right after a valid code is typed in, the handset displays "Network unlocked” or “Network unlock successful”.
