SIM lock:

A SIM lock, NETWORK-LOCK, Carrier Lock, imei lock or (master) subsidy lock is a technical limit built into GSM and CDMA mobile devices by producers for use by service providers to restrict the usage of these phones to specific countries and/or networks. This is unlike a mobile phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions.The reason why several carriers SIM lock their smartphones is because they provide cell phones at a low cost to consumers in exchange for a contract to cover the use of the network for a specific time period, commonly between one and three years. This business model permits the organization to recoup the price of the device covering the lifetime of the contract. Many of these savings are worth as much as several hundred US dollars.

Unlocking Technology:

A handset can be unlocked by entering a code provided by the network operator. Alternative mechanisms include software working on the handset or a computer or laptop connected to the handset, hardware devices that connect to the mobile or over-the-air by the carrier. Typically the unlock operation is permanent. The code needed to remove all locks from a smartphone is referred to as the master code, network code key, or multi-lock code. Generally if the handset is carrier locked it will typically display one of the following messages: SIM network PIN blocked, Enter lock PIN.


Mobile phone suppliers have financial incentives both to strengthen SIM lock protection (which placates mobile phone network organisations and enables exclusivity discounts) and to weaken it (widening a mobile phone's overall appeal to consumers that are usually not interested in the service provider that offers it).
