Hey Adam - you sadly forgot to mention the phone model you intend to and unlock and whether it is a network unlock (so the phone can be used with all National networks) or a security PIN/Password that has been forgotten. For network unlock though, you can either purchase it from a third party like sim-unlock.net or from the carrier under which the phone is currently locked to. As for a PIN/password, you will please try and resubmit including the model of the phone as the reset tend to differ from one manufacturer to the next and equally from one model to the next.
