Hi,

Do the websites which claim to unlock phone actually work?

If so which one is best?

Thanks

iPhones need to be unlocked by Apple (excluding jailbreak), while some companies may have an inside line to the apple database the common method is to go via the mobile network.

If you are not the original owner or don't know the original owner - it is not easy/possible to get it unlocked via the network.

Sorry i cant help with the websites.

I've no idea but I got my old phone unlocked before selling it and it cost me £20 which I recovered in the price I sold it at.

T-mobile did it in about 3 days.

Better and cheaper going to your network from free upto £20.
