If the phone was supplied by Vodafone, and it won't work with another
SIM card, this is likely to be because the phone is locked to the
Vodafone network.

To unlock it, you'll need a Network Unlock Code (NUC). Vodafone can
supply this.

I'd suggest getting in touch via the web form at
www.vodafone.co.uk/contactus. Make sure you include the make and model
of your phone and 15 digit IMEI number (found by keying *#06# SEND on
your phone).

In the meantime, it's best not to attempt to enter anything else, as
entering the wrong code several times can permanently block the phone.

If the phone is less than 12 months old, there will be a charge of
£19.99 for the code.
