Does the SIM work in your old phone?
Or another unlocked phone?
Are you sure that the new phone is unlocked for use on any network?
What make and model of phone is it?
If it's an iPhone then there's probably the usual Apple iPhone BS to deal with.
This needs cash credit on the account to pay for the SMS(s) that the iPhone sends automatically to a UK activation server (8c per UK SMS).
Hope this helps.
