What is a SIM lock?
Skip contentThe service provider placed the lock in the phone to make sure your phone can only be used on their network. We are used to thinking about locks as strong mechanical devices, that physically prevent us from entering somewhere, but fortunately the lock used in the phone is only a software setting, and so can be easily changed. The lock may be accessed by opening a normally concealed menu, so that the unlock code can be entered and the phone can then be unlocked.
