Hi, a few months ago I requested the NAC Code for my Galaxy S7 Edge.

Now, when my sister tried a few days ago she forgot about the Code and entered it wrong 3 times, so the phone is now asking for the PUK. The PUK however isn't accepted by the phone either. They have tried it with different SIM Cards as well (and the phone right away asks for the puk) but it doesn't accept any of the SIM card's puk numbers. What can we do about that? Is there a possibility to reset it by requesting a new NAC Code maybe?

Mods - I'm not sure when PUK codes became a thing with NAC's so this has thrown me a bit (I know Steps in real life and asked her to post here)

 

I had thought PUK codes were tied to the SIM card only. 

 

Steps has tried both PUK codes tied to her sin without success so I'm wondering if perhaps NAC PUKs are somewhat different to win PUKs?

PUK's are completely linked to the sim card.

Did you try a different sim in the phone? Did you put a sim card lock on the phone?

We have tried several Sim Cards now but as soon as the SIM card is in it asks for the puk, no longer for the NAC code.
In the email that I received with the NAC Code it says "If the incorrect Vodafone Network Assignment Code is entered more than 3 times, the phone becomes blocked and the PUK is required to re-activate it." But as I said, it won't accept either of the puk numbers that we entered.

You'd need to find the original sim card that was in it before the sim was locked. Typically if you enter the NAC code wrong too many times it locks the phone completely and requires a manufacturer to unlock it.

If it's asking for the PUK then the sim card unlock code was put in wrong too often. The PUK request has nothing to do with the NAC code. I suspect your sister entered the wrong sim code in too many times and now it requires the PUK code. Maybe if you PM a mod the sim number of the card that was in the phone when the error occured they may be able to get you the PUK code.

See i had thought that as well - but the NAC instructions that i received 

 

Note: Please insert Non Vodafone Ireland SIM card in your mobile when you unlock it

 

If the incorrect Vodafone Network Assignment Code is entered more than 3 times, the phone becomes blocked and the PUK is required to re-activate it.

1.         Ensure the phone contains a Non Vodafone SIM card.

2.         Power on the phone.

3.         A pop up message asking to input the NAC will appear.

4.         Input the NAC.

 

So if i have a non Vodafone sim in the phone, and the incorrect NAC is entered (which seems to be the case here), the NAC is then required to unblock it - one would think the NAC code should not be aware of my NAC as there is a completly different non Vodafone Sim in the device. Here is where the logic was breaking down for me.

 

If the PUK needed was the PUK of the non vodafone sim inserted, then this wouldnt exactly act as a secure method to unblock as the person that entered the NAC wrong should have their own PUK anyway.

 

If it is the original SIm cards PUK, then is the NAC now tied to the active Sims PUK when it is generated?

 

I just find it odd that the PUK is being asked for with an unlock.

 

The Sim card itself being used to unlock is not blocked, it works in other phones by just entering the Pin - so the issue is elsewhere.

The NAC should not be aware of the PUK code at all. Did yee try the PUK code for the non Vodafone sim? I would have thought the PUK for the non sim would just allow you to re-enter the NAC code. In 21 years of mobile unlocking I've never seen what you're describing. I've entered an incorrect NAC too many times and then needed a manufacturer to reset it but never seen a request for a PUK code.

I know it's crazy right?

 

But the unlock email we received does state that if the NAC is entered incorrectly multiple times and locks, to ensure a non Vodafone Sim is entered and enter the PUK.

 

Which just makes no sense to me.

 

Yes, tri ed PUK 1 & 2 of both the original SIM and the current non Vodafone Sim currently inserted without success

It may need to go back to the manufacturer.
