Dear all,
I need help!I have an unbranded Galaxy S and I usually update the firmware without any problem(until now!!). Few days ago I flashed for the first time JM5 firmware without any problem. Today I had to reflash the JM5 firmware. Everything was ok but when I booted my phone I had the message: "SIM network unlock PIN"!!!!I'm going crazy because I cannot unlock the SIM!!!What's happened? Please help me!!I tried to reflash with an old firmware but no chance to reset!!How can I proceed?
Thank you
Contact your operator for your PIN code, unless you have it in the letter that you got with your SIM card.
EDIT:
Actually: Did you buy the device from Handtec?
According to this thread, they got a batch of Orange-locked phones where they should've been unlocked.
Return the device to them to get a new unlocked one.
The problem is that the phone worked properly without any restriction for 20 days with the same SIM and now I noticed this problem!!!
I cannot also unlock my phone via websites that provide this kind of codes because I don't really know also the name of the opeator that is locking my phone!!
I think that this is an internal problem of phone but I don't know how to fix it.
Other ideas?
What on Earth, same issue here.
My phone just randomly got locked.

What do you mean? Do you mean that sometimes you are able to use your phone e sometimes no? How do you unlock your your phone?
I think that you have an imported device that was unlocked from the seller. When you have restored the factory settings, probably the unlock was... wiped... I have had the same problem after a factory reset; I'm Italian and my Galaxy is an imported item from Hungary or Austria, but I don't know the original provider that locked the device. I have phoned the Samsung Customer Care (the seller is on vacation until the end of august ) and, from the IMEI, they told me only that the device was producted for the Austrian market. Without the provider it's no easy to unlock the phone, but there is a service that I'm trying: unlocksamsung.co.uk - they are partner of Mobileunlocked.co.uk, but unlock only samsung and only using the IMEI number of the phone. In the meanwhile I've ordered a I-Smartsim 2008 from Ebay...
Bye.
Did you try reflashing a different firmware?

All from JF1 to JM5.
so that means the lock in the firmware ? I was under the impression that is was not.

No, the network lock is firmware independent. I was able to flash various firmware without problems in first days. The lock appeared after the first Factory Reset using the vol-up+home+power combo.

I can confirm that the network lock is firmware independent, however my phone went into network lock before Factory Reset.
I did however try Factory Reset to fix it and it didn't help, nor did flashing several other roms, including the stock rom.
I contacted the point of sale and apparently they had a previous issue with a batch of phones but they did not expect it to happen again.
I hope if a replacement isn't honoured then we need to find a solution... :\

Once it showed up I haven't been able to use my phone as a phone.
When you enter your SIM PIN (if you have one), it then jumps to a full screen that asks for a NETWORK UNLOCK PIN.
Just to clarify, this is not PUK or PUK2, as I can use my sim in another phone just fine. ( G1 actually. )
Did you buy your phone from handtec? If so your phone is probably locked to Orange UK.

I don't know. I'm Italian, I bought it as an import "free" device and maybe the phone is from Austria or Hungary. I hope in a software workaround in the future. For now I'm waiting (and hoping in) an unlock code and/or the unlock sim buyed on ebay (till seller reopen at the end of the month...).
Bye.
Just to understand what this issue is about: now, when your phone is trying to connect to the Network, it checks your device's IMEI as "locked" and then negotiate a PIN Dialog?

Now that is REALLY scary.. Can you please try to remember what you did, or what program were you using -->right before<-- the network lock got restored ???! Something must have made the Factory Reset trigger...
Same thing happened to me 2 days ago. I removed the sim from my phone and I left it without battery for ~16hours. When I put the sim back, I got the same message to enter SIM network unlock PIN.
Fortunately for me, my phone was unlocked via an unlocking service and I had the NCK code. The trick is that I cannot unlock the phone again using this code, but I can lock it to my network with it.
The weird thing is that now I can use my phone both on the network that it was previously locked and on the network that i locked it. So, my phone is now locked on 2 networks And the other thing is: I can enter as many unlock codes that I want. it is no more limited to 3 tries.

Tell me, have you unlocked it after you bought it?

rbnet.it, let me try to clear things out and understand it:
A - Wasn't your phone dead?
B - What program did you use to check your locks?
Also i'd like to leave some general question for anyone who knows:
C - Do you think that if a galaxy S user unlocks its phone online using some kind of site, the phone will eventually lock himself up again?
D - Are the locks "predictable"? I mean, will the phone always do Network-Lock or always do Sim-Lock?
This scares me out a lot, my phone is locked to "TMN" (network only) but everything is OK as long as it stays that way... But i'm starting to believe that it won't

A: No, it isn't dead It's network-locked on a foreign countries/provider: I can't use the phone section (call, mobile networks, etc) within Italian providers, but if I dismiss the pin request (or leave out the SIM), I can use any other functions.
B: a samsung code that check the status of the phone: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=721111

Good news guys.
I contacted Handtec ( Place of purchase. ) and apparently it's a issue with Samsung Firmware or something.
The guy sent me a network unlock code, and it seems to work.
I haven't got the prompt again.
That's just what I was wishing for =)
Since yaz00us told us that his phone locked himself up, it had to be a Samsung Bug.
By the way, does the given code work for future times? If so i might ask mine right away... =)
thanks for the good news
I like to share my experience, in June 22nd this year i purchased unlock code from an online company Cellunlock.net that have stores on Quebec and Montreal and Laval Canada and Hallandale Florida to unlock my
T-Mobile Vibrant SGH-T959
firmware 2.2
Baseband: T959UVKB5
Kernel version: 2.6.32.9
Build Number: FROYO.UVKB5.
The unlocked code i was given never trigger the phone to unlock it successfully i try:
1: Power on without sim, type in #0111*unlocked code# then i hit dial and o get message "Not registered to network"
2: Power on without sim, type in #7465625*638*unlock code# then i hit dial and o get message "Not registered to network"
3: power on with At&t sim card and i get prompt to enter the network code and message: unlocked unsuccessful
I even made a video and sent it to them upon their request so they can see that i was doing the steps to unlock the phone correctly.
So since i live in fort Lauderdale and they have an office 20 minutes from where i live they suggested to go there so their technician can unlock it by hooking it up to a machine which it turn out to be Z3x Box (i look it up), first attempt it looks like it unlocked it but went i got home and turn the phone back on wiht my ATT card and the phone did not recognized any network, even went i try to use itwiht th original T-mobile card, so after few E-mail i went back to their office and i spend about 2 1/2hr with the technician wich he proceed to flash the phone several times due the phone after it supposed to be flash successfully with the Z3x box either the phone work with ATT but not wiht Tmobile, or the phone kept rebooting itself, after it will says 1 time flashing the phone the phone never turn back ON again, so the technician suggested to leave the phone with them so ty can try to fix it with another technician of may be the battery was dead, so i left my phone with the charger this was o July 7th, since this date they told me they had sent the phone to Samsung and they were waiting for them to returned it.......up to today i still have no phone and i have to E-mail them for status and every time they say the same thing.....what you guys thing i should do next or do i have any chance to get my phone back?
Maybe they think your Vibrant is the Canadian version of vibrant? The bell vibrant or something?
IDK how it can be just YOUR phone thats doing that though, i'd assume the unlock code is the problem? but then again they did try that z3x box too...
Did they give you more than one unlock code to try out?
The vibrant has T-mobile on top, they never give me another unlocked code they mention that maybe the IMEI number was incorrect on the phone from Samsung it slef because we verify the IMEI number when they had my phone, As i mention the technician work on the phone for 2 1/2 hrs. untill it died.
Why didn't you just call your carrier to unlock it?
Because i had another phone wich i call them to unlocked and they said i had to wait another 90 days to unlock another one, i needed the phone unlock to use went i travel to south america and i could not wait. at the time.
Can't you odin to factory 2.1 and get a app in market that will give you the unlock code for free? There was a program on here when the vibrant first came out that when you hooked it to you pc it would find your unlock code then you just put in a different carrier sim enter the unlock code, well that's what I did.
EDIT HERE this might help if you want to do it yourself don't know if it still works, but I know that the whole was in 2.1 eclair that we could get the unlock code thank button is here>>>>>>>>>>>>>VVV
They have the phone for more than 2 months and still waiting for them to sent it back to me.
Moved..............
Ok, I'm a noob, but I do not hate myself, and I have done a search for similar threads. None apply.
Here's the situation:
I received a used Samsung Captivate with Gingerbread on it from a co-worker, who upgraded to a Galaxy SII. He erased all his personal info/data, but I don't have the details.
I called AT&T, since I'm a customer in good standing, and since the Captivate is not subject to a contract. I asked for an unlock code. They gave it to me. I put it in the dialog, and it did not work. I got something along the lines of "Network unlock unsuccessful. You have 9 attempts left." Not the EXACT wording, but it gets the point across. AT&T and I checked and re-checked the IMEI, and they kept generating the exact same unlock code (which is 8 digits).
In all, I've spent 3-4 hours on the phone with AT&T service, and about an hour with Samsung service, which is where AT&T sent me after they couldn't figure out why the phone wouldn't unlock.
With one attempt left, Samsung said the phone needed to be reflashed, and sent me a UPS label to send it in. So I did. They replaced a component by the power port, reflashed, and sent it back to me. So, stupid me, I tried the unlock code again, after twice again verifying the IMEI. Now, the phone says "Network unlock PIN number is entered incorrectly. Contact your Service Provider," when I put in a T-Mobile SIM to test. (Yes, I know I can only get EDGE on the Captivate on T-Mobile.)
I called Samsung, and they said they don't know why it wouldn't work, and that the unlock code was indeed correct, and that the mainboard probably needs to be replaced.
Has anyone ever heard of this? Does this sound logical? Am I dead in the water unless the mainboard is replaced, unless I want to use AT&T exclusively? I had hoped to be able to use a foreign SIM when I go out of the country, but it looks like this is no longer possible, unless the mainboard is replaced.
An AT&T GoPhone SIM works just fine.
Thanks,
Tracy
What happened most likely appears to be a miscommunication. Do you know what excatly they flashed ?
Personally speaking, without going through AT&T route, I myself have used the Galaxy_S Unlock by Helroz which works like a charm. ( you need to be rooted though)
They flashed Froyo 2.2 I897UCKB2. I was considering rooting and flashing a new ROM, but having searched for unlock info before calling AT&T, I learned that in Gingerbread, they hid the unlock code. Thus my reason for calling AT&T (since I didn't want to pay for something I could get from AT&T for free). I'm glad I didn't do any rooting or flashing before I sent the phone back to Samsung. I have NO problem experimenting once I either: 1) know for sure I can never unlock the phone, or 2) can successfully unlock it. I don't want to have to undo a bunch of stuff before I send it back to Samsung. I'm lazy.
From what I was told by AT&T and Samsung, once you've used up your attempts, you're permanently locked to the original network.
Thanks!
About I guess 6 months ago there was a little app that would let you root your phone temporarily. It stayed rooted until you reboot. It worked very well. I used it a lot until I rooted my Captivate for good. Unfortunately I can't find my copy of it. I did a quick search here and didn't run into it either. It may be worth a try if you can find it.
If you root the phone, unlock it with the the app mentioned before, then do a factory reset, you will no longer be rooted, but the unlock will be there. Once you unlock a phone, it stays that way unless you decide to relock it. When you unlock the phone, it will put a folder on your phone. Keep that folder in a safe place. Just to be safe, copy and save it in multiple places. If you ever want to relock the phone you will need that folder.
Cool, thanks, guys. I'll look for the app and try it out.

My wife and I just switched over to t-mobile about a month ago and at&t wasn't much help in getting our phones unlocked either. The gave us unlock codes for some other phone.
I used the same app that theevildevil mentioned, Galaxy_S Unlock by Helroz on my phone. On my wife's phone I used Samsung Galaxy S Unlock Tool by DaGentooBoy. Her phone was running a gingerbread ROM. Mine even had a screwed up IMIE number. Both apps worked great though.
ZeroG1, how many digits were your unlock codes? I ask because Samsung thinks AT&T gave me the number for the wrong thing.
Thanks,
Tracy
Hi to all
I have a Stock AT&T Note 3 on KitKat, And I bought the unlock code from a website and the Code was working fine
I sent my phone to the Samsung repair center in TX to fix the memory card slot problem.
After a week they sent the phone back to me, and Of course the phone is back to the original settings
When I turned on the phone and inserted my T-mobile Sim card, the phone is asking me for the network
unlock code, so I entered the same code that I used before and it is not working ...
Thanks
You probably didn't get the exact phone you sent them. They probably sent a different one. Check for an old receipt, or the original box for the imei code. See if it's different then the new one. It most likely is. If it is, you will need to obtain a new unlock code.
I checked the IMEI number and they matched
I also thought of that it might have to do with the unlock code
so I ordered another Unlock code from a different site
and it turned out to be the SAME Unlock code from the other site !!
Yes there's only 1 unlock code per imei. It doesn't matter where you obtain the code, it will be the same.
I hate to tell you this, but you'll need to contact the warranty dept and probably send the phone back. Again :'(

Do you think this has anything to do with the Region lock restriction ?
No I don't believe it to be related to region lock.
Check one more thing for me please. Verify that the imei of the phone is what you believe it to be. Open settings and in "about phone" check under status and verify the imei is what you think it is. You can also Press * # 0 6 # on your keypad, Press 'Call' or 'Send' as if making a call. Your IMEI number will be retrieved and displayed on your screen.

do you know anything about this ?
NOTES: If you have a Samsung Galaxy S3, S4, Note 2, Note 3 or your Android version is Android 4.4 (KITKAT): All SAMSUNG devices manufactured after the date of JULY 2013 and Samsung devices running on Android version is Android 4.4 (KITKAT) are subject to REGION LOCKING. If your phone has been used previously with the original carrier, this will not apply to you. However, if your device is BRAND NEW, your must activate it with the original carrier. If your Samsung device becomes Region locked, you will not be able to fully factory Unlock your Samsung devices so it can be used internationally. Even the correct code will not work anymore. In order for your Samsung device NOT to be region locked, you MUST activate (FIRST USE) your S3, S4, NOTE 2, NOTE 3 with your ORIGINAL carrier at least ONCE to take your region lock OFF. After your Region lock is off, you can Sim Unlock your device via Unlock Code. All Canadian Carriers are NOT subject to Region Locking. All USA and European Carriers ARE subject to Region Locking. Region lock is removed automatically after you activate your device with its original carrier. Make some calls before unlocking. (Insert an active original sim card into the device and make a few calls to activate the phone and bypass the region lock. Once you've activated the phone, you can input the unlock code.)
Well after reading that I'm amazed. I believed region lock was based on where you lived and used the phone. Like a person in Europe couldn't use an at&t phone overseas until it was used in the states. I was unaware a person in the U.S. had to do the same if they were using it in the U.S. but with a different carrier. My apologies.
You wouldn't happen to know anyone on at&t would you? Maybe a Samsung rep in bestbuy can help you with borrowing an at&t sim and making a call or 2 on your phone.

I tried to use someone's ATT sim and it doesnt work
Also Samsung is telling me that "as you have unlocked the device from third party site , and this is not considered as official unlock for the device"
I might bring the phone to bestbuy and let them check it out.. since the phone is still under Warranty
There's defiantly something wrong if an at&t sim doesn't work. Are you the original owner? If not do you know the original purchaser? It could have been blacklisted.

The phone is working Fine with an ATT sim card, it has signals
it is just that it is not working after I inserted my tmobile sim card
and entered in the unlock code... So the imei should be fine !
I believe you need approximately 5 to 15 minutes of use on an at&t sim card from my previous readings of other user experiences.

ive owned a sony z1 for a few years now and love it, but broke my screen twice in a month, i have my current phone with half the screen working.
my girlfriend works at a cellphone store and a customer forgot / left / didnt care / his sony z1 at the store a year or so ago so its rotting on a shelf and she brough it home for me to see if i could use it as a replacement.
the phone is network locked. i dont know what carrier the phone had, ive rooted it thinking there might be a work around
anyone know if i can unlock the network without sending the imei and 50$ to some website? without knowing what carrier it might cost me a few attempts...
any help would be awesome
The phone can't be unlocked without a code.
Check the APN settings to see if they give you a clue about the network the phone was originally used on.

the phone was factory reset when it wasnt claimed , guess ill just go for the cheapest one and maybe do it twice.
If you are confident the phone still has the oem firmware, you can edit the build.prop file and look for the CDA number (starts with 12xx, followed by a dash and four other numbers), then grab a copy of xperifirm and look for that code. This will at least show which carrier the phone was customized for.
