What is Carrier Unlock Code?

A carrier unlock code, also known as a network unlock code, or a SIM unlock code, is a unique code that is used to unlock a mobile phone from its original network or carrier. When a mobile phone is locked to a particular network, it means that the phone can only be used on that network and cannot be used on any other network. A carrier unlock code is used to remove this restriction, allowing the mobile phone to be used on any network that is compatible with the phone’s specifications.
