Samsung Galaxy S8 network unlock request unsuccessful

[NickT57]

I have received an NUC code from Vodafone and on entering it into the handset I got the message that it was unsuccessful.

It appears for some Samsung phones I need a Master Key or code as well as a NUC. How do I get a master code?

Many thanks, I have raised the matter with them and am awaiting a master code from Samsung.

You're very welcome @NickT57 

Hopefully the Mastercode along with the Nuc and an activated non Vodafone sim card will resolve this for you.

The only other option would have been a reputable online unlocking site which would come at a cost from the unlocking site.

I wish you all the best with this.

Although it took nearly 10 days to get the Master code from Samsung, I have now resolved this issue, thanks for your advice.
