SIM lock:

A simlock, Network Lock, Carrier-Lock, IMEI-Lock or (MASTER) SUBSIDY lock serves as a technical limitation built into CDMA and GSM smartphones by producers to be used by providers to restrict the usage of these phones to a particular locations and/or networks. This is contrary to a mobile phone (retrospectively called SIM-free or unlocked) that doesn't enforce any SIM limitations.Generally if the devices had not been locked, users might possibly sign an agreement with a particular supplier, obtain the low priced phone, then stop paying the monthly bill (thus breaking the agreement) and start using the smartphone on another mobile phone network or maybe sell the device for a profit. SIM locking curbs this by prohibiting a change of mobile phone network (using a new SIM).

Unlocking Technology:

Commonly, a locked phone will display a message if a restricted SIM is used, asking for the unlock code. On new phone models operating on Android mobile phone software, the smartphone is going to show a message stating “SIM network unlock PIN” or “Enter Network Lock Control Key” if it is network locked. Windows phones will show the message, “This SIM card can only be used on specific networks. Contact your customer service center for the unlock code”. Hopefully you should be sure what an IMEI number is and how you can obtain it from a smartphone, but why do you need it? The chief uses of getting the I.M.E.I. number is to allow a cell phone to get unlocked so you can use it on another network, doubtlessly saving you big by changing to a cheaper plan.

As soon as a valid code is typed in, the mobile will display "Network unlocked” or “Network unlock successful”.


Smartphone makers have financial incentives both to strengthen SIM lock protection (which placates mobile phone network organisations and allows exclusivity discounts) and weaken it (expanding a phone's allure to buyers that may not be interested in the provider that offers it). At the same time, making it too hard to unlock a mobile might make it considerably less desirable to network service providers who have a legal liability to provide unlock codes for some devices or in particular countries.

Unlocking Services:

Various companies provide a IMEI mobile phone unlocking service . This service requires those people whom wish to unlock a mobile phone handset to provide their IMEI number to a service supplier and sometimes they will also need the country and cellular network the device is locked to, frequently sent through email or submitted on their web site. The supplier then will supply (once you have paid) an unlock code for the phone.
