Based on the phone's data, such as: the brand and model, its IMEI serial number and the network of the service provider it is locked for, a unique unlocking code is generated. After inputting the unlock code on the phone's keypad the simlock is disabled. The remote unlocking mechanism does not require any cables or additional software. Remote simlock unlocking is the simplest method of removing the SIMLOCK lock.

Disabling the simlock by entering a unique unlocking code on the phone's keypad is an option introduced by the manufacturer, hence - a checked, safe and efficient method.

The limitation has been implemented in the mobile phone in such a way, that it can operate with SIM cards of only one specific service provider. Remote unlocking with the use of a code disables this protection and extends the usability of a phone, thus making it possible to use SIM cards of all networks' service providers from all over the world.
