Welcome to Vodafone Community
I have recently obtained a NUC code for my old LG G6 as I have upgraded and want to give the G6 to a family member who is not on Vodafone. I have followed the instructions given by Vodafone . But when I have selected Service Provider Lock, it doesn't give me the option to put the NUC in. It comes up with a message " Your phone is not personalized "
Any help would be fantastic!
The first thing to do is to make sure the alternative network SIM card is activated. If this has not been done the NUC won't work.
If you are still unable to unlock the phone after following the information from Vodafone taken from this link Use your Unlock Code please come back to the forum.
