A SIM-LOCK, NETWORK LOCK, Carrier Lock, imei lock or (MASTER) subsidy lock is actually a technical limitation built into GSM and CDMA mobile phone devices by producers for use by service providers to limit the usage of these phones to specific countries and/or networks. This is in comparison with a phone (retrospectively called SIM-free or unlocked) that doesn't enforce any SIM limitations.The reason lots of carriers SIM lock their handsets is simply because they offer phones at a low cost to customers in exchange for a contract to fund using the network for a given timeframe, generally between one to three years. This business model permits the business to recover the price of the mobile phone over the lifetime of the contract. Many of these reductions are worth close to a couple of hundred US dollars.

A phone can be unlocked simply by entering a code provided by the service operator.

If the handset is carrier locked it will typically show one of the following messages: SIM network PIN blocked, Enter lock PIN.
