HI there. I seem to be having the same problem that everyone else seems to be experiencing. I have obtained two PUK codes and also a NUC code. None of these work. Customer service at Vodafone is appalling and no one seems to help or offer advice. I've read about a Mastercode that I thought I had requested but after 10 working days just provided with the NUC code. Can someone please help as this seems to be an on going problem and this does not put Vodafone in a good light.

Some Samsung phones need a mastercode also known as an unfreeze code which customer service should be able to provide which is in addition to the Nuc @Anthony010 


Customer service on 191 or Live Chat should be able to provide this.


That or contact the Vodafone Social Media Teams via Facebook and Twitter.


My apologies at having to send you elsewhere to engage with Vodafone UK as I appreciate you came here , signed up and created a post to reach out for help but the Team here can no longer help with Account based issues.


But it's the same Social Media Teams here that help and assist via Facebook and Twitter.


Things have changed as they have decided that help and assistance with account based issues would be best supported that way.


I appreciate not everyone wants to use Social Media however it takes but a few moments to create a Twitter or Facebook account and then can be forgotten if necessary. Just a thought.
