Hello ladies and gentlemen,
I would like to add my recent experiences on this subject. I have a Nokia 515 on the Vodaphone network. I have been offered a very good deal with BT. I managed to obtain Both PAC and NUC codes thru Vodaphone but when I tried to enter what I thought was the unblocking code( NUC )it was rejected. I then discovered that there exists a further code Access Control Code. Vodaphone say they don't know what that is or where to obtain it. BT don't seem to know anything about it either. I have tried some of the internet solutions, no luck. This is a blatant and sinister device to block any consumer choice I thought I had. Disgusting!!
