What is a NETWORK LOCK
SIM lock:
A SIM lock, NETWORK-LOCK, carrier-lock, IMEI-Lock or (MASTER) SUBSIDY lock is actually a technical restriction built into GSM and CDMA mobiles by manufacturers to be used by carrier networks to restrict the usage of these phones to a particular locations and/or networks. This is contrary to a phone (retrospectively called SIM-free or unlocked) which doesn't impose any SIM restrictions.The reason lots of carriers SIM lock their phones is that they offer phones at a discount to customers in exchange for a contract to cover the use of the network for a given time period, commonly between one to three years. This business model permits the company to recoup the cost of the phone across the life of the contract. Such discounts are worth as much as a couple of hundred US dollars.
Unlocking Technology:
A mobile can be unlocked simply by entering a code provided by the network operator. Different mechanisms consist of software working on the handset or a computer or laptop connected to the phone, hardware devices that link to the mobile or over-the-air by the provider. Almost always the unlock procedure is permanent. The code required to do away with all locks from a cell phone is called the master code, network code key, or multi-lock code. Generally if the device is carrier locked it will generally show one of the following messages: SIM network PIN blocked, Enter lock PIN.
Economics:
Mobile companies have commercial incentives both to strengthen SIM lock protection (which placates service companies and will allow exclusivity deals) and also to weaken it (increasing a handset's overall appeal to users that may not be interested in the service provider that offers it). Also, making it too tough to unlock a mobile may make it significantly less desirable to network service providers with a legal obligation to provide unlock codes for certain handsets or in specific countries.

This service calls for individuals whom need to unlock a mobile phone to provide their IMEI number to a unlocking company and quite often they will also need the country and network the device is locked to, frequently sent by email or entered on their web-site. The company then will provide (for a fee) an unlock code for the mobile phone.
