Welcome to Vodafone Community
I have used the two codes sent via email (following the initial email code not working) but am getting a message saying "SIM Unlock Unsussful".
I then used *#*#7378423#*#* and this I think told me 0 tries left. What can be done next?
Unfortunately if that's the case then your phone is probably hard locked and will need for Vodafone to send away to have it's counter reset so you can them attempt the Nuc again @MattEtheridge
