cheers in advance for any help

Whoever gave you the phone needs to unlock it for you, or call the provider and have them unlock it for you.

We will not give out unlock codes, as there are some shaddy characters out there who either steal phones or find them and don't turn them in as they should, and then come here or to other forums trying to find a way to get them unlocked so they can use them.
