SIM lock:

A sim-lock, NETWORK LOCK, carrier lock, IMEI LOCK or (MASTER) SUBSIDY lock is really a technical limitation built into GSM and CDMA mobile phones by producers to be used by carriers to restrict the use of these phones to particular countries and/or networks. This is contrary to a mobile phone (retrospectively called SIM-free or unlocked) that doesn't enforce any SIM constraints.Unlocking a cellphone is virtually universally legal. Also, it is legal for carriers to force SIM locks for certain time periods, varying by region.

Unlocking Technology:

Normally, a locked device will display a message if a restricted SIM is used, asking for the unlock code. On modern phone models working on Android operating system software, the smartphone should display a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if it's network locked. Windows phones are going to show the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Other handsets may well display varying messages for example , "Enter special code" or "Enter unlocking code," or in some instances the mobile will probably display a message stating it's locked. The minute a valid code is keyed in, the phone will display "Network unlocked” or “Network unlock successful”.


On many occasions a SIM-locked phone is sold at a considerably lower cost than an unlocked one on the grounds that the company expects income via its service. SIM locks are applied on inexpensive (pay-as-you-go) units, despite the fact that deals on costlier handsets need a subscription that delivers guaranteed income. Unlocked phones have a a lot higher market value.

Unlocking Services:

Several organizations provide a unlocking service . This service calls for people whom need to unlock a mobile phone to supply their IMEI number to a unlocking company and sometimes they will also ask for the country and cellular network the mobile phone is locked to, either sent through email or submitted on their web-site. The organization then will supply (for a fee) the unlock code for the mobile.
