Unlock Code Not Working

[Renato]

I asked a code to unlock my o2 Phone, Galaxy Note 8 (N950F)

I inserted the other carrier sim card and type the code, the message was, code didn't' work.

What I can do in these cases? Go to an O2 store or take my mobile to Samsung? The contract ended this month.

@Renato 

Firstly, DO NOT keep entering the wrong code as it will permanently lock the phone.

Ensure you have requested the correct code Guide: Unlocking an O2 phone to use a different SIM card 

If all fails, send a message to @Marjo or @Martin-O2 for help.

Hello MI5,

I tried once, didn't work I stopped.

Yes, I requested by myo2. (Case Ref. 1173693635 (KMM1932881722I15977L0KM))

@Marjo @Martin-O2 Guys, can you help with this one?

Thanks

[MI5]

Hang on and one of them will be in touch tomorrow.

Thanks for the mention @MI5. 

@Renato I can get someone to look into this for you. I'll need some details so I'll drop you a message.

@Renato I have an update for you on this one. Our Guru team have requested the master unlock code for your phone from Samsung to make certain we get it right and don't permanently lock the handset. 

It can take up to 10 days so I'll drop you a message as soon as it comes through. 

[Renato]

Thank you very much, sir.

I'll be waiting.

[Renato]

Replying just to keep the post open.

Thanks

No worries @Renato we won't do anything with the thread until your issue has been solved.

It didn't work.

When I insert the new carrier sim, ask for a PUK code, I contacted O2 to ask about my PUK, O2 told me one, but don't work either.

Don't know what to try anymore.
