What is a imeilock
SIM lock:
A sim lock, NETWORK-LOCK, CARRIER-LOCK, imei lock or (master) subsidy lock is actually a technical limit built into CDMA and GSM cellular phones by producers for use by carrier networks to limit the use of these phones to particular countries and/or networks. This is as opposed to a cell phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions.In the event the mobile handsets weren't locked, customers may sign an agreement with one particular organization, obtain the marked down phone, then stop paying the monthly payment (thus breaking the contract) and start using the cellphone on a different network or even sell the device for a profit. SIM locking reduces this by prohibiting a change of supplier (using a new SIM).
Unlocking Technology:
Commonly, a locked device will display a message if a restricted SIM is used, requesting the unlock code. On the latest phone models running Android mobile phone software, the cellphone will show a message stating “SIM network unlock PIN” or “Enter Network Lock Control Key” if it's 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 might display differing messages including "Enter special code" or "Enter unlocking code," or in some cases the phone will simply present a message saying that it's locked. When a valid code is keyed in, the mobile phone displays "Network unlocked” or “Network unlock successful”.
Economics:
Mobile handset makers have economic incentives both to strengthen SIM lock security (which placates network organisations and allows exclusivity discounts) and to weaken it (extending a mobile phone's overall appeal to consumers who aren't interested in the service provider that offers it). Moreover, making it too tough to unlock a mobile might make it a lot less attractive to network service providers who've a legal liability to supply unlock codes for some devices or in particular countries.
Unlocking Services:
A certain amount of companies offer a network unlocking service . This service calls for those people who want to unlock a mobile phone handset to give their IMEI number to a service supplier and often they will also need the country and cellular network the mobile phone handset is locked to, sometimes sent through email or entered on their web-site. The company will then provide (at a cost to you) a unlock code for the mobile phone.
Unlocking Service Providers:
Regrettably there are a great deal of dodgy service providers active in the mobile phone IMEI unlocking industry. Consequently it is prudent to be sure you find a honest provider for such a service.
