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.
