"SIM Suddenly *Perso* Locked?!" <-- (Thread Tittle Typo)
Hello XDA. Mayhaps you can help me solve a problem that came out of literally nowhere.
I'm using an AT&T Galaxy Note II on Metro PCS with Cyanogenmod 13, and I have been using this setup for a few months now with almost no issues. Now don't get me wrong, I've had some hiccups here and there. Random reboots, camera issues, once I even lost ALL of my personal data for seemingly no reason at all.
Right this very moment, however, my phone just randomly rebooted, which I'm used to, but upon unlocking my phone after startup all I get is "Unlock Sim Network Pin" - "Sim Perso Locked Emergency Calls Only"
I have NO idea what is going on or why this happened in the first place. I don't have the slightest clue on how to fix this at this hour other than paying for an unlock code from a third party, but there's no way I'm doing that! Please help.
TL;DR
My phone rebooted and now the SIM is locked for no reason. Pls hlp
How did you sim unlock the phone in order to use Metro PCS? You mean the sim is locked in that the sim card is asking for a pin?

When I bought the phone off of a friend they asked at&t to unlock it and they obliged.
Yes, that's exactly what I mean. Every time I restart the phone it asks for a pin to unlock SIM.
I'll update with screenshots.
Once the phone is unlocked via code, it should be permanently network unlocked. Do you still have the unlock code?
If the sim is asking for a pin, sounds like a setting in the security may have been changed to prompt for a pin. Did you try entering 1234 or 0000?
Same thing just happened to me, what was your solution? Phone worked fine yesterday, powered down from battery use, when I plugged it back /charged it, it was doing the perso lock thing.

I just got my new S3. Does anyone know what is the default unlock SIM PIN? I wanted to change the PIN no. So that I can lock the SIM card.
Thank you

The default sim pin for AT&T is "1111", I'm not sure if they would be the same, but I don't see why they would be different...

Just call T-mobile, they will give it to you.
Called. She has to put me in hold for like 4 times and then come back to me and ask why do I need the default unlock SIM no.
Are you kidding me?!

Correct me if I'm wrong, when you lock the sim, don't YOU enter the pin code yourself?

1. Are you trying to unlock your SIM to be able to use your phone with other carriers or
2. are you trying to change SIM PIN code which is not really unlocking. BTW, if i'm not mistaken there 2 PINs for SIM
If the answer is #1, then this will help you http://forum.xda-developers.com/showthread.php?t=1820253
if #2, then I have no idea, nor do i understand why you need it
I want to have personal PIN for my SIM CARD. If someone steal my phone they won't be able to make phone call from my account after they restart the phone.
Thanks guys. I already got the default PIN no.

Or you can just call t-mobile and ask them to temporary suspend your line cuz your phone was lost/stolen
Does anyone know where to find video call option in S3 it's not present in the dialer.

default t-mobile sim PIN
I was under the impression at first that the "Set up SIM card LOCK" related to the locked status of the device as it related to using other carriers SIMs. Then I come to find out, it really related to the PIN code on the SIM card. I did some research, and the default PIN is not the same as the UNLOCK code T-Mobile sends people for unlocking the devices for travel/etc. It is a separate code for password protection on the SIM: 1234
Enter this, and you can then change the PIN to whatever you want. This code is like a password to use the SIM card itself so no one else can use it or your service without the code on their phone. You can also store your address book/etc on the SIM that cannot be accessed without the PIN.
If anyone else looks this up, here are the default codes for AT&T and T-Mobile again:
AT&T GSM SIM PIN default code: 1111
T-Mobile GSM SIM PIN default code: 1234
Verizon GSM SIM PIN default code: 1111
edit: after further research, you may be aware that if your phone code blocked due to entry of wrong PIN too many times, and you requested the PUK code to fix it, the default SIM PIN may be reset to 0000 or another code. That is what the Verizon instructions page says. I hear after entering the carrier provided PUK code, it unlocks the SIM, too. IDK if the default SIM PIN remains 1111/1234 or changes after that. Just be aware it might if you can't get it to work.
Depending on the device, some devices password protect the SIM code lock screen with a Security code, which is '0000' such as the LG Encore. Just look up the respective guide in Google about this before getting stuck entering the wrong code on the wrong screen. For Android devices, you will go to "Settings->Security->Sim code lock->Set up SIM card lock->Tap Lock SIM card/Enter PIN to use device" without being hassled by this Security code - it is a unchecked box until you enter the above code. Then after entering it, it becomes checked. And you can then tap "Change SIM PIN" below. Good luck, and don't forget this code.
If you run into trouble, contact your carrier for PUK unlock issues, etc. The phone sometimes becomes locked when you enter the wrong PIN too many times when trying to figure this out. The PUK code can only be given by your carrier to unlock it if the security mode kicks in and blocks you.
My phone recently got locked in puk mode. When i took it to T-Mobile the lady reset it and told me thre new code was something like 1001 or 1101. So i need to know if anyone knows the basic sim pin codes they would use?
Aren't puk codes unique to a SIM card?
Hi,
I am new to GSM technology moving over from CDMA technology (US Cellular) and have a question about unlocking the phone so you can use it on another network. Once I put in a foreign SIM card and unlock it with the NCK code does the phone stay unlocked or every time you put in a different SIM card you have to reenter the code?
stays unlocked, you just need to do it once.

Unlocking a phone with a code is a permanent change however there are instances where we've seen some models reactivate the lock when someone has changed the software on their phone. Usually this doesn't happen and it is rate that it does but if so, then the same codes can be used to remove the lock again.
The only time the unlock codes won't work on a phone they have in the past is when the IMEI of the phone has been changed. This only happens if a phone is repaired and an engineer changes the IMEI - it won't happen randomly.
Hi Guys long time learcher, first time poster so please be kind if my n00bness starts to shine through.
So recently I brought a Tesco Branded Wildfire S A510e (believe 2012 model) second-hand. As soon as it came I used this site with my Macbook Air and got the phone bootloader unlocked, recovery finally installed and lastly flashed a nice custom rom with a new kernel.
My new network SIM card came through today, i decided to go with giffgaff because like tesco they are actually using the O2 network so I thought the SIM card would be compatible with the handset but alas as soon as I booted into my phone I was greeted with a SIM network unlock PIN prompt.
I done a bit of research and I discovered that my phone is SIM-LOCKED (if thats what S-ON means??) and to get it off I need to buy some kind of XTC Clip but unfortunately am feeling the pinch at the mo so I can't afford to order one. Instead I paid for a network unlock code from mobileunlocked.com (had used them before with a locked blackberry). I sent them my IMEI number, paid and waited for about 10 minutes and my unlock code arrived.
Eagerly I entered the code and it was accepted, the phone then displayed my menu screen etc. But I also noticed that I have no signal on the phone, i tried to scan for the network but I just got a "Error while searching for networks", I thought it might need a reboot so I did.
But when it booted up it asked me for the network unlock code again, I entered it again, it was accepted and the phone then displayed my menu screen but once again no signal, I tried to search for the network and once again same Error while searching message.
I shutdown the phone and manage to borrow my sons Tesco SIM to test, popped it in and turned it on. No code asked for, booted straight into the menu and looked, the phone has signal.
Tried my GiffGaff SIM again and still same problem. If I wait a message does pop up saying "mobile registered on network" but when I try to search for a network carrier a search prompt pops up for about half-a-second but then closes, No network operators are listed.
Has anyone else ever had this kind of problem??
Any feedback will be appreciated.
Thanks for reading.
I don't see where you activated the SIM that you got from GiffGaff. If you didn't, go to their site and click on, "Activate SIM" and follow the prompts.
Hello there,
Exactly the same thing happened to me yesterday also with a Wildfire S, and I found a way around it.
I flashed a stock ROM (Gingerbread, HTC Sense), and entered the unlock code, which actually unlocked the phone (calls and all).
After that I re-flashed the custom ROM I'd used previously and didn't get prompted for a code, the phone is still unlocked.
I have this I317m locked to bell. I am trying to use it on virgin mobile canada. From what I've read, I shouldn't have to unlock it to use it on virgin. Anyway, when I insert my virgin sim card, sometimes it'll say unregistered sim and other times it'll just tell me emergency call only. When I look under status, it knows my phone number and it knows that there is a sim card inserted, but it won't let me connect to anything. It's completely stock and on 4.4.2. It never asks to enter an unlock code when booted up and no combination of any symbols and numbers that I have found on the web results in anything happening through the dialer. I have an unlock code for it and I cannot input it anywhere. I am starting to think that I have a hardware issue of some kind and hope that it can be confirmed with help from you guys. Any advice would be greatly appreciated.
So it can pick up virgin under available networks, it just can't register on anything. This time, when I turned it on, it read virgin for a split second on the lock screen then switched to unregistered sim and then to just emergency calls only. It has bars showing up, I just can't connect to anything. strange.
Well, I have it all apart now and figured for the $7.69 it costs for a new sim reader and micro sd reader, I'll give it a shot.I kinda have a feeling that it not the issue though. I'm kinda leaning toward the nand being fried or something like that.
Have you checked that the IMEI was clean?
The imei comes up under about phone and matches the sticker. What else is there to check? It also shows up doing the #*06# trick.
Aha! Checked IMEI. Not clean. Will fix properly now. Thanks.
Which normally means you're in possession of a lost, unpaid or stolen device...
I ordered an unlock code from imei-unlocker a couple weeks back and when I got the code, i entered it and it supposedly sim unlocked my ATT G3. I tried to put my t-mobile sim into my device and the phone acted as if it didn't have a sim in it. I factory resetted it and the same thing happens, "No Sim" error. I borrowed my uncle's AT&T sim into the G3 and it still didn't work, I even tried factory resetting it again. I don't have any options to add in unlock codes any more because when I dial the number to get to the screen where I enter the unlock code, every option is greyed out. I don't know what's happening and I was planning on re-selling it but now, I don't even know if the phone will take a SIM anymore. Any idea guys?
Anyone got any ideas =/
