SIM lock:

A simlock, Network Lock, Carrier-Lock, imei lock or (Master) subsidy lock serves as a technical restriction built into CDMA and GSM smartphones by manufacturers for use by service providers to restrict the use of these phones to specific locations and/or networks. This is not like a mobile phone (retrospectively called SIM-free or unlocked) which doesn't impose any SIM constraints.

Almost all mobile phones can be unlocked to work with any GSM network provider, however phone may still display the original branding and may not support popular features of the new service provider. Aside from the locking, smartphones might also have firmware installed on them which is specific to the mobile phone network provider. This firmware is installed through the service provider which is separate from the locking mechanism. Most smartphones can be unbranded by re-flashing an alternative firmware type, a process suitable for advanced users only.

Alternative mechanisms contain software running on the device or a computer or laptop connected to the handset, hardware devices that attach to the handset or over-the-air by the carrier.

If the device is carrier locked it will usually show one of these messages: SIM network PIN blocked, Enter lock PIN.

SIM locks are applied on inexpensive (pay-as-you-go) devices, despite the fact that bargains on costlier handsets need a subscription that provides guaranteed income. Unlocked handsets have a improved market value.
