I bought Samsung galaxy s8+ SM-G955F in Poland. I did 6 minutes phone call with local carrier sim card to do region unlock for other carriers sim cards. Unfortunately, when she came back to my country and fitted into the phone local sim card I received pin code request. So I tried to fit in another sim cards form different local carriers an it was the same message. Then I tried to type in PIN code of my sim card, that is exactly known, and it was not take effect. Now phone is asking PUK code. But that sim card works perfect with Samsung galaxy s7 edge without any pin or puk requests.

Welcome to Samsung Support. Please allow me a moment to read through your enquiry.

Hi there Leonid, thanks for getting in touch with us today!

I can see through reading through your query that this is an issue you would need to contact your service provider about.

Is there anything else I can help you with at all today?

Me	09:07:56

But I tried many others sim cards form other carriers and it was the same problem.

When we fitted in UK O3 sim card it works without pin or puk requests.

Samsung	09:10:00

Ok, bear with me a second

Me	09:10:15

ok, thank you

Samsung	09:10:33

So, does the device work with a UK sim card in the UK?

Me	09:12:47

Device worked with UK sim card in my country. My father was here couple of days (he is UK citizen), and we tried he's sim card.

Samsung	09:16:34

Ok, some UK networks have corresponding carrier networks in various countries so you can use your device while travelling abroad without the need to change SIM cards. I think that may have been why your fathers SIM card worked. Can I ask where you bought the device from? was it bought from a Samsung retailer, or from a network carrier?

Me	09:18:39

I bought it in Poland, Euro Net in Gliwice. and I have all documents confirming phone purchase.

Samsung	09:20:11

And is Euro net a network provider? Like O2 or Vodafone in the UK

Me	09:21:56

No it is not network provider. At the phone box was a warning "European sim card only". I did more than 6 min phone call with local carrier sim card to do region unlock. unfortunately it was not take effect.

Samsung	09:22:40

So you rang a phone box in Poland from your mobile for 6 minutes?

Me	09:23:28

Exactly right, sir.

Samsung	09:23:41

Ok, that is why your device isn't region unlocked

You should of been advised to make a 5 minute phone call to another mobile device, ringing a landline would not activate the region unlock

Me	09:24:16

How can I fix this problem?

Samsung	09:24:36

did you see my previous message there Leonid?

Me	09:25:33

Yes, but now in my country I have not polish sim card or other European sim card to do it

Is there is another solution to unlock the phone?

I heard that Samsung may give me unlock code. I have all purchase documents.

Samsung	09:29:55

It's not guaranteed to work, but you could try using a SIM card you know works like a UK O2 SIM, like your fathers, and make a 6 minute call with that to another EU mobile device. That may work, but I couldnt guarantee it. We do not have those codes to give out, the locks are put on devices by network carriers themselves

Me	09:32:17

If I came back to Poland I be able to unlock the phone?

Samsung	09:33:23

That is actually the most obvious solution to your problem... I just didn't want to suggest it straight of the bat, as travelling across Europe seemed a little extreme

But a 6 minute phone call to another EU mobile device in Poland should solve your problem. But it must be an EU registered phone, with an EU network provider

Me	09:37:39

Would you be so kind to ask some one else about how to fix that problem? As you said travelling to Europe is not so good solution. And I do not know where I can reach EU registered sim card here.

But thank you anyway.

Samsung	09:39:01

I already asked 6 colleagues. The General consensus was either getting a sim on the same network as your father and just using that, the solution I suggested earlier, or going back to Poland

But other than that trying your local network providers and see if any of them could help with your issue

Me	09:41:00

Ok, thank you so much.

Samsung	09:41:42

Thank you, you enjoy the rest of your day, and I hope someone can help you locally... Just to make you aware, you have come through to Samsung UK

Perhaps contacting Samsung in your region may offer help, they would have a better understanding of network carriers in your region

Me	09:43:06

I will try contact them. Have a nice day.
