SIM lock:

A sim lock, Network-Lock, Carrier-Lock, imei lock or (Master) subsidy lock is really a technical restriction built into GSM and CDMA phones by producers to be used by carriers to restrict the use of these phones to specific locations and/or networks. This is contrary to a cell phone (retrospectively called SIM-free or unlocked) that does not enforce any SIM constraints.


Unlocking Technology:

A phone can be unlocked simply by entering a code provided by the service operator. Alternative mechanisms consist of software running on the device or a computer or laptop connected to the handset, hardware devices that link to the device or over-the-air by the carrier. Almost always the unlock procedure is permanent. The code required to eliminate all locks from a cell phone is known as the master code, network code key, or multi-lock code. If the phone is network locked it will usually display one of these messages: SIM network PIN blocked, Enter lock PIN.


Economics:

Quite often a SIM-locked handset is sold at a noticeably lower price than an unlocked one because the service provider expects income thru its service. SIM locks are employed on lower priced (pay-as-you-go) units, while discounts on more pricey handsets require a subscription that gives guaranteed income. Unlocked mobile phones have a improved market value.
