SIM lock:

A SIM-Lock, NETWORK LOCK, CARRIER-LOCK, IMEI-Lock or (master) SUBSIDY lock is a technical restriction built into GSM and CDMA mobiles by manufacturers to be used by carrier networks to limit the usage of these phones to particular countries and/or networks. This is as opposed to a mobile phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions.Unlocking a cell phone is nearly universally legal. At the same time, it's legal for providers to force SIM locks for certain periods of time, varying by region.


Unlocking Technology:

Usually, a locked phone will display a message if a restricted SIM is used, requesting the unlock code. On recent phone models operating on Google android software, the phone is going to show a message stating “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones should show the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Several other devices could display differing messages such as "Enter special code" or "Enter unlocking code," or in some instances the device will probably present a message stating it's locked. Once a valid code is typed in, the phone will display "Network unlocked” or “Network unlock successful”.
