You can fix this. Or at least you can try to fix it.

I've used the method described in the Sim Unlock thread to generate my code, but I can't get the unlock code request (dialogue box) to come up on the phone. I've turned it off and inserted a different SIM (it was originally O2, now it's GiffGaff, although I believe they use the O2 network) but I don't get the prompt to enter my unlock code. I can scan for networks and register on the O2 network, but I get No Service errors.
Tried a variety of ROMS. I got asked for the code on a Cyanogen one but it always refused it and asked for it at every boot. I've also SuperCID'd to 11111111.
Any clues?
Just reset phone to 1.78 stock and on first boot spotted a message "Restricted Access Changed". Does this mean anything?
So it would appear that putting a GiffGaff sim into an O2 locked phone won't trigger the unlock request. But putting a T-Mobile one in does. It's accepted the code, but I'm still getting 0 bars of reception.
Does anyone has any ideas?
Having an issue with a newly picked up at&t P907a and looking for a little help.
Love the note pro but when I add a sim the pro recognizes that it has been inserted and a pop up asks to be restarted to connect to the network.
Once restarted it simply says 'no sim installed' and won't let me into the mobile networks part of the android settings to change any networks etc..
Running stock at&t as it has been factory reset.
I've been assured this pro is unlocked but starting to have my suspicious...
Anyone else come up against this?
Thanks.
Call AT&T or go on their website and do live chat, they will look up the IMEI and can unlock it for you.

Thanks Jargin,
So the issue I'm having is because the pro is not unlocked? Have you had the same issue with it saying no Sim installed?
I've been told that if you put in an unsupported Sim in one it will ask for an unlock code rather than just displaying no sim..
No after reboot my device asked for an unlock code. I would take it to a store, maybe someone entered too many won't pin codes, that can happen too.
Hello. Half a year i bought D6603 that was connected to some uk provider, the man i bought from had unlock code. So on first run we inserted sim that is not acceptable, so it asked for unlock code, after code was inserted, sim lock was unlocked.
Now, i had a problem with my phone, so i brought ir to repair center, after all fixes they reinstalled OS , and after that, now i cant use my sim card. i wanted to insert that code again that i have, but it not allows it. when i go to that "secret" menu of sony, in sim card section i see all parameters are 0, so that means that enabling all simcards by code are disabled.
Please help, how i can unlock my phone, that i could use my own sim card? I have that unlock code, but i can't insert it and unlock.
Thanks.
P.S. now i have tried to hard reset it as it shown in this video:
youtube.com/watch?v=4al5k-mooc8
after this "hardreset", in secret menu , sim lock tab shows not zeros anymore, but unknown error.
Hi guys,
a friend of mine told me that your are the only persons they maybe can help me....i really hope so!
I bought a S8+ which is A1 Mobilkom Austria locked. As i want it with a another carrier "3 Hutchison Austria" i ordered a sim unlock Code from a third Party Company. After i got the Code i tried that like the instruction says:
#####################################
Instructions to release your SM-G955F Galaxy S8 Plus
1. - Turn on the handset on with a SIM card not accepted by the device (your new network operator)
2. - If the card has a PIN number, enter it and press OK.
3. - The device will prompt: “Network lock”, Now enter XXXXXXXX and press OK.
4. - Your phone will indicate: "The operation was successful", becoming permanently unlocked.
Minor code: If the code in step 3 does not work, type the code XXXXXXXX and press Unlock, the phone will indicate Unlock fail, now dial the code again from step 3.
######################################
I really don´t know if i did something wrong...after 3times it is locked now.
After that i am getting this message now "SIM Network PIN blocked. Enter SIM Network PUK" - But now the Problem Begins. I tried to put in the PUK Code um my 3 Hutchison Sim Card but that was
unsuccessfull. So it seems it doenst men the PUK of the sim, it means the PUK of the network lock.
Do i have to contact A1 for that Code? That would cost me 150€ and tehy will give me the sim unlock Code. But i do not Need the sim unlock Code, i need the PUK unlock Code....so maybe
i buy it but i alos do net get the PUK Code.
What can i do now?
Pleeeeeease help me!!
P.S. I am from Austria, vienna - Sorry for my not perfect english
Thanks in advance

Whoah, take it easy...
You title says, "S8+ blocked after trying to unlock". But your description says that your SIM card is PUK blocked?
If the phone boots perfectly without any cards in, then the SIMcard is blocked. Then you need to order a new SIM card for the new carrier, cus you cannot unlock a SIMcard that has been PUK blocked...
It feels like you type the Carrier unlock code instead of the PIN for the SIMcard?

Thats the Problem. I have the PUK Code from my 3 Hutchison SIM Card but that one does not work. I took this sim Card and put it into a another phone which is unlocked and it worked fine. So it can´t be the simcard PUK. If it should be the simcard PUK, then the sim Card wouldnt work in a another phone , right?
I tried few minutes ago a anonther 3 Hutchison sim Card from a collegue (he has the sim pin and the Sim PUK with him) and it also doesnt work!
Thats really weird, it sounds like the SIM PUK ( i know the error message Sound like that) but it means the Network PUK.
I think there should be a another Code ewhich you Need, if yout put the carrier unlock wrong into the phone...
thanks in advance

1.) This means you again tried to unlock the phone 3 times with your friend's 3-SIM card and again ended with the PUK message?
2.) Or did the PUK message appear right from the start with the other 3-SIM in?
If 1. then looks like the bought unlock PIN is not working at all.
If 2. then
-->
Do you know anyone who could borrow you an A1 SIM card for a test, who has also a PUK available?
OK, finally my phone is working with the 3 Hutchison sim Card now
Solution:
I ordered a new unlock code which includes a UNFREEZE Code from a another company. I was telling them my problem and the told me it should be the unfreeze code which i was needed.
After typing the unfreeze code into my phone it asks me for the net unlock code...i typed the new net unlock code into my phone and i can use all cards now!
Thanks for your support guys :good:

I have the same problem, my phone is asking me for the
"Sim network PIN. Enter SIM network PUK."
Wich company did you use to get the code? help me!! haha
I used sim-unlock.at (Austrian Company) but you just need a company who also provides you the unfreeze code with the netlock code.
Some company just send you the netlock code, some are sending you a pack of codes...
Hope this will help you
I also have the same problem but I'm in Ghana, can my service provider help me provide me with the unfreeze code, I really need help, really cost me much to get this phone, Please help me, Phone keep asking me for a PUK even with a new SIM card in it

You may need to configure the APN for the new carrier manually. Go to settings, connections, mobile network, then APN (Access Point Names), select add and type in new APN settings.
However if that doesn't work, It may be hard locked. Meaning that an invalid sim unlock code was entered too many times. In my past experiences if it doesn't prompt you for the code when you enter a new sim card it is either hard locked or already unlocked and needs the APN settings configured. However after inserting a new sim card the phone would normally configure the APN automatically and only on occasion would I need to modify it to get data/text working properly.

invalid sim card,sim card not supported means it is locked device, i would like to help you to unlock it if you're interested
I'm facing this same issue. When I got the phone I installed an unbranded firmware (XAA/XAA/ATT) and I've since upgrade to Oreo. I can't seem to restore an ATT firmware so I can be prompted to enter the unlock code. Any suggestions?
make sure you using non at&t sim and it must be an active sim card. submit an unlock request to at&t on their website or use an unlock service like attunlocker.us to get your code.

The issue is there's no prompt to enter the unlock code.
is the SIM card active that you are using? what SIM is it?

Yes, it's a T-mobile SIM.
Sorry to necro, but does no one have a solution for this? I've seen plenty of threads such as this but very few solutions.
Necro double-post, I'm really asking for it...
First, you have to get an unlock code from the carrier. I had AT&T and it told me my phone was active under an account (previous owner). When you call AT&T and ask for an ulock they loop you to the website and you can't progress there, so you just have to ask for "customer service" twice and then get to the second level support. They can get you an 8 digit code for unlock. But I still never got prompted for the code and neither AT&T (5 calls), Cricket (3 calls), or xFinity (3 calls) could tell me how to get to the unlock screen. The following did it.
My solution was to use the following method, as found on https://www.tenorshare.com/samsung/samsung-unlock-code.html:
Step 1: Open the phone and type #7465625*638*# in the dialer.
Step 2: Then, it will ask for the Samsung Reset Code, it is an 8-digit code.
Step 3: Provide it and you will be done.
