SIM lock:

A simlock, network-lock, CARRIER-LOCK, imei-lock or (master) subsidy lock is actually a technical constraint built into GSM and CDMA cellular phones by producers for use by providers to restrict using these phones to particular locations and/or networks. This is contrary to a mobile phone (retrospectively called SIM-free or unlocked) that doesn't impose any SIM constraints.




Unlocking Technology:

Frequently, a locked handset will show a message if a restricted SIM is used, asking for the unlock code. On the latest phone models running Android software, the cellphone is going to show a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones should display the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Other devices may display different messages for example "Enter special code" or "Enter unlocking code," or in some instances the phone will probably present a message stating it's locked. Right after a valid code is typed in, the mobile displays "Network unlocked” or “Network unlock successful”.


Economics:

Phone companies have economic incentives both to bolster SIM lock security (which placates network organisations and will allow exclusivity offers) as well as to weaken it (increasing a phone's allure to consumers that are not interested in the provider that offers it). At the same time, making it very hard to unlock a smartphone may possibly make it considerably less appealing to network service providers who have a legal duty to offer unlock codes for some handsets or in selected countries.


Unlocking Services:

Some organizations provide a remote phone unlocking service . This service calls for those people that need to unlock a mobile phone handset to supply their IMEI number to a service supplier and quite often they will also need the country and service provider the mobile phone is locked to, frequently sent through email or submitted on their website. The organization then will provide (at a cost to you) an unlock code for the handset. For many manufacturers as in Nokia and Samsung a variety of services also offer unique remote-unlocking software with directions, where a cable is needed to remove the SIM lock from home. Such companies may email the unlocking code or software which can remotely unlock the unit. The price for unlocking a cell phone will change based on the network it's locked to and the smartphone model itself, as every unlock code is unique to each specific device.
