Mobile phone unlocking is a systematic process of allowing a mobile phone to “accept” SIM cards that are registered from other telecommunication companies or carriers.

Basically, a mobile phone contains a software program that blocks SIM cards from other carriers to be used. So the phone is “locked” exclusively to its carrier. And in order to unlock the phone, another simple software is patched to bypass the original locking program and enable the mobile device to read SIM cards that are registered from other carriers.
