Network Unlock Code Received, but not successful

[rabailey]

Receveived email to unlock Vodafone Samsung A3.

"Your unlock code is 4149513. Just to confirm, this is for your device with the IMEI serial number 35965....."

Turned on the phone with a different (O2) sim.  Got asked to enter to this unlock code

But message: unlock was unsuccessful.

Multiple attempts.

Please help me to unlock this phone

Hello Rachel. 

Some Samsung Phones need a mastercode as well as the nuc. 

Here is a thread with some in. 

Mastercode.

If that does not help then Samsung Customer services maybe able to provide a mastercode but can't help with the actual unlocking. 

And or customer service on 191 or Live Chat can escalate this to the Vodafone Nuc Department and give you their email address too.

@rabailey If you need any further help with unlocking your Samsung A3, please contact our team directly using the link in my private message. 

We'll be able to check on the status for you and escalate it to our NUC team if needed 🙂

Fixed this, finally.  The Network Unlock Code we were originally given by Vodafone was missing the leading zero.

Putting a 0 at the beginning of the code worked perfectly.

Thanks for all those who offered help.

Every Time I use Unlock Code on Huawe Y6 2019

It is always saying "Unlock Code Unsuccessful" Even though I put a Zero on unlock code & I have only 3 attempts left,

Please Help !

Hey @Robert1992, have you completed our NUC form here; to get your code? Have you checked that the IMEI you've provided is correct? 

If so, have you tried the following steps to insert your NUC: 

1.  Insert an activated alternative SIM card
2. Your Huawei Y6 2019 will ask for SIM network unlock PIN
3. Enter the code received
