This will depend on what type of SIM lock you are talking about.
One is when your phone asks for a passcode or a PUK passcode to unlock the SIM. If you are having trouble with remembering the correct code, you may need to contact your phone company (carrier) for help.

The other is when your phone is locked to a particular phone company (carrier) and will not accept SIMs from any other carrier. Only the phone company to whom the phone is locked can unlock the phone – and they might – or might not – choose to do so.
