SIM lock:

A sim-lock, network-lock, CARRIER LOCK, IMEI LOCK or (Master) subsidy lock is a technical limit built into CDMA and GSM mobiles by manufacturers to be used by providers to restrict the use of these phones to specific countries and/or networks. This is not like a cell phone (retrospectively called SIM-free or unlocked) that doesn't enforce any SIM constraints.The main reason several carriers SIM lock their phones is simply because they offer smartphones at a discount to customers in exchange for a contract to pay for using the network for a specific period of time, in most cases between one to three years. This business model permits the organization to recover the price of the mobile phone across the life of the agreement. These kinds of reductions are worth around a couple of hundred US dollars.


Unlocking Technology:

A handset can be unlocked by entering a code provided by the service operator. Different mechanisms contain software running on the device or a pc connected to the device, hardware devices that connect to the handset or over-the-air by the provider. In most cases the unlock operation is permanent. The code needed to do away with all locks from a cellphone is called the master code, network code key, or multi-lock code. Generally if the phone is network locked it will usually display one of these messages: SIM network PIN blocked, Enter lock PIN.


Economics:

Smartphone companies have financial incentives both to enhance SIM lock protection (which placates network providers and will allow exclusivity discounts) as well as to weaken it (widening a mobile phone's appeal to consumers that may not be interested in the provider that offers it). Furthermore, making it too hard to unlock a phone may possibly make it less desirable to network service providers that have a legal liability to offer unlock codes for certain devices or in particular countries.


Unlocking Services:

A certain amount of companies provide a online smartphone unlocking service . This service calls for people who would like to unlock a phone to give their IMEI number to a unlocking company and frequently they will also ask for the country and service provider the device is locked to, sometimes sent through email or entered on their web-site. The supplier will then supply (once you have paid) the unlock code for the mobile phone handset. For a few brands as in Nokia and Samsung many services also offer unique remote-unlocking software with directions, when a cable connection is necessary to remove the SIM lock from home. Such companies may well email the unlocking code or software that will remotely unlock the device. The price for unlocking a phone may deviate based on the network its locked to and the mobile phone model itself, as every unlock code is unique to each unique device.


Unlocking Service Providers:

Regrettably there are many of dodgy web sites active in the smart-phone imei unlocking industry. As a consequence it is advisable to ensure you use a trustworthy provider for these services. Do your due diligence and investigate every potential retailers before committing to making an order.
