[Q] Lumia 900 SIM Unlock (no PIN and PUK tries left) - Nokia Lumia 900

Hey guys
Just a couple of months ago I got my lumia 900 as a gift.. However it was AT&T SIM Locked.
Checking through some forums and combing through the internet I found out that the PIN Code given by AT&T sometimes didn't work when requested for the PIN code but instead when PUK Code was asked.
I must sadly say, I tried using my given pin code for my PUK including my current network's simPUK code but all failed.
Now I have no attempts and I cannot seem to enter the PIN Code given not even the PUK code..
Can someone please let me know a simpler way to unlock this phone? I have software flashed numerous times but the PUK or PIN code isn't resetting.. Please do let me know!
Thank you so very much.

HELP!! h6315 wont unlock with official code

I have a h6315 tmobile locked phone purchased from ebay. It came with an unlock code. It wont unlock. I called tmobile, they sent me the official unlock code which matches the one given to me with the phone. Here are the steps I've been doing for 1 month to try to get it to work on cingular.
I've tried, using a live cingular 64k sim.
Unlock Error: your phone is not ready for unlocking
(h6315 wont work with 64k sims supposubly)
I've tried, using a live tmobile sim.
Picks up signal and works.
Unlock Error:unlock code not accepted
Had friend call tmobile, got unlock code. Same code as before.
I've tried flashing the rom with 1.00.38eng.
Put tmobile live sim in.
Unlock Error:unlock code not accepted
I bought a 32k cingular sim. Activated it. It works on other phones.
Unlock error:your phone is not ready for unlocking.
Does anyone have any ideas what else to do? I've read that some of the h6315 will never unlock. I guess I might have found the needle in the haystack.
Any help is greatly appreciated!!
Thanx!

PUK unlocking tool please. Thanks!

Hi guys, I hope you guys have a tool where I could find out the PUK code of my blocked sim. I'm in the Philippines and using a prepaid sim and I lost the card where the PUK is placed as well.. Our Network Provider can not give the PUK code for prepaid subscribers. I hope you could help me out on this as I badly need the number itself. thanks!
Sorry mate, we deal only with the phones here, NOT sims...
Customer Service SHOULD have the PUK codes for your sim. Doenst matter if you are prepaid or not. Now if it says SIM BLOCKED, you are outta luck, theres no way to unlock it from there.
It does actually matter black_joker. T-mobile here in the uk use randomly generated puk codes for sims and they also cannot provide a puk code for your sim if you have lost the card that came with it.
Really? Hmm. I never knew that. Now I'm interested. Will definately have to look into that one now.
PUK
I've just got the same problem with my phone. And I think the only solution is to get a new SIM with the same number from your Network Provider.
Yes... at the moment. I've actually been working on it. Out of 10 PUK Locked Sims, I managed to unlock 2. Hope to have it perfected here soon. Wish me luck!

Kaiser sim unlocker worked but can't enter code.

I just recently bought my first smart phone from a friend. He told me we could get the unlock code from at&t. I was given the wrong code. Not knowing it was the wrong one I tried it a few times, 5 times to be exact. I have seen it posted on a few threads and was told by at&t, after i had tried the code, that after five attempts the phone is permanantly locked. I tried the kaiser sim unlocker but the phone still won't let me confirm the code. Is my phone permanantly locked or is it possible to still unlock it? The phone is a HTC Kaiser 8925. If anybody has any answers it would be much appreciated.

Unlocking Lumia 900 -- AT&T SIM/Network Lock Code Is Incorrect - FIXED!

You've probably found your way here because you're trying to use an unlock code that you got from AT&T or an EBay seller, but the phone is refusing to take it, despite your triple-checking of details.
The workaround is this: Enter the incorrect code until you run out of your ten (10) attempts. Then you'll get the *real* network unlock message, with 32 attempts. Enter the same 8-digit code you've been entering, and voila, you're now free to use this on any network!
Attached is a video showing proof of unlocking using this method (sorry for the blurriness and quick cut at the end--was too excited that this unlocking ordeal is over):

minhtien for the initial hint to try this method
pyk for being the 1st guinea pig
My credit card company, who I knew I could call up if something was wrong with this phone and that it was truly un-unlockable
Please rep/sticky! I don't care about karma/rep here. Just want to share this helpful hint with everyone. I've spent maybe 12 hours researching fixes and workarounds, and just dove right in to using up my unlock attempts.
Thanks!!! It worked for me. I was nervous, but I figured the worst case is I return the phone.
I was able to unlock two different Lumia 900s with this method.
Thank you very much :fingers-crossed:
good news. I had same issue. I tried 4 times then I stopped. Now I need call AT&T again to get the unlock code because I threw it away.

Thank you very much this method does work, this is how i unlocked my phone. Nobody else couldn't help me at AT&T. This is why i love our community here at xda developers. and thanks to Breex243 for finding this method, i'm sure this will help a lot of people from this point on.
Verified! It worked like charms. Credit to minhtien, Breex243.

Thank you - this worked perfectly for me. Used up all my initial attempts, and the phone immediately said "32 attempts remaining". Then got it on the first try with the ATT provided code.
What if I can't even receive any code from AT&T or third-party? (they say the unlock code for my phone's imei number is not their system) Would it work with any 8 digit number?
Here is my imei number: 359746040748761 I've tried getting the code from AT&T and three different sellers on ebay, but no luck. Any help would be appreciated.
It does work!

Hi Diego, it might be that your device was indeed blacklisted/was tied to a non-paying account. You'll need the specific 8-digit unlock code.
Got the unlock code from AT&T and kept saying "Incorrect PIN" so I did get scared. Once I saw this post, I bit the bullet and used up all my attempts until it finally asked for the PUK code. Put in the same unlock code one more time and it worked.
Verified with Smart micro-SIM card from the Philippines and works great.
Thanks!

Wouldn't AT&T let me know if it was blacklisted or tied to a non-paying account when I called them for the code? That may be the case though, since I bought it used from Ebay.
Thankyou!!

Awesome! Thanks for the post. I had bought my wife a lumia and I was getting desperate!
Kudos!

I have been struggling with AT&T to fix this issue. But, this form helped and made my day. Thanks a ton. Thanks to the blog GSM, who redirected me here.
Worked for me also.. thanks alot... entered 10 times and then on the PUK screen..thanks heaps!
I got the phone from ebay. It was loaked to AT&T and after talking to the guys there I got the unlock code from them. I double thriple checked the unlock code and entered 4 times which indicated as incorrect pin. I'm not in USA, so no point of having a locked phone which could not be used here.
Please help.....
Finaly I've got my phone unlocked thanks to xda... I had already used 5 attempts but goving the fact that no point of keeping the phone locked which could not be used in my country, I've tried the balance attempts and then the phone asked for the PUK code. I've entered the same code..
It worked.... Thanks a lot.. I can assure you that, if you have got the code verified from AT&T and other third party places what they have given you is the PUK code..
It works...It works... I'm over the moon.. :laugh:

Wut. Why would you use all of those attempts when the instructions are to only use the 1st 10? You should have sought out assistance when the code didn't work the first time with your 32 attempts. Anyone know how to help this guy out?

SIM network unlock PIN

So I got my hands a new Nexus 5X from an EE retail store in UK, although I'm happy to use EE for everyday use there are times when I travel and need to swap SIMs due to black spots. Much to my horror and bemusement I discovered that my brand new 5X is indeed network locked, so there's that myth put to bed for non believers.
I have requested an unlock code from the network, unfortunately patience is not one of my strong points, does anyone know of any sites that offer an unlock for the 5X? I tried one this morning but it came back 'no code found'. If anyone knows of a site that can help, I'd appreciate a PM with the details.
Thanks.
For what is worth, I also got, from. my local carrier a brand new Nexus 5X. LG H790. Well, it turns out to be Network locked as well. Whenever the phone is turned on with the SIM in of another carrier it asks for: "SIM Network Unlock PIN"
I went on and bought online from two different companies sim unlock codes, from the first company: SimUnlock dot com was not able to found a code and after a few days, said so snd proceed to reimburse me.The second company: MasterUnlock dot com did return, very quickly (fte minutes after online purchase) a few codes, named
NCK NSCK SPCK CPCK SIMCK, tried the NCK and the SPCK as per the instructions received but none worked "unlock unsucessful", seems they are also reimbursing me.
So, I dont know whats next, as the carrier wont give out the unlock codes.
My Nexus 5X is locked to Mexico's carrier Telcel.
I have just had this exact same issue (EE UK). I didn't realise this was now a thing! I honestly thought these companies had grown up by now. but apparently not.
Has anyone come across a solution to these? If not, does anyone know if these codes are carrier specific and individual, or generic?
I'd appreciate any info anyone has on this as it's a new thing to me!
