Hi Tcall.
I work for Vodafone and may be able to help.
If you have recieved the handset from Vodafone directly, it will be locked to our network.
It can be unlocked at any time during the contract for a charge of £20, or, free of charge once you've had the phone for 12mths.
If you wand us to issue the unlocking code for your handset, if you go to
www.vodafone.co.uk, then contact us, you will be able to send us an email. If you include FIT135 in the body of the text, it will be picked up by a team who monitor the public forums, and will be able to help.
