NUC code for Samsung A70 doesn't work

2: Seeker

I am going abroad and need to unlock my phone. I have requested the NUC code to Vodafone, which was provided very quickly, but it doesn't work at all. I tried to get support online using Toby, but this tool is useless. Can anyone help please?

Is the alternative network sim card your using activated i.e connects to mobile data etc  ?

To add some Samsung phones need a mastercode also known as an unfreeze code as well as the Nuc.


Customer service on 191 or Live Chat can provide this.


The unlocking needs to be processed before you leave the UK as Vodafone cannot guarantee the Nuc will work outside the UK.

The best place for help and support is through the previous unlocking threads, if you ask the question, these will come up.


From the sound of things, you need to ask Vodafone for a master code, (also known as an MSK code or an unfreeze code)  This is entered first followed by the NUC code.
