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.

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?

How does one change the settings to allow a PIN authentication before the usage of phone everytime? I tried to activate the PIN under the 'Phone Settings' option but it seems that it already has an old PIN which i am not aware of and until one knows that, it wont let a new PIN be set up. As a cautionary note, there are only 3 chances to set the PIN, i dont know what happens if you fail at all three attempts...may be it'll lock the phone/ SIM? Does anybody know more on this....care to share!
Thanks
You wanto go the the 'Lock' settings and setup that your phone locks itself after so many minutes and what password you want to unlock it.
Unlike traditional GSM phones, Windows Mobile does not use the GSM Pin mechanism due to the fact that Windows Mobile did not originate as a phone device and thus used its own locking mechanism.
I imagine you could lock the SIM card by entering the wrong PIN or if you flagged in the SIM card itself that a PIN needed to be entered to active the SIM (as thats how the GSM technology works in that even if you transfer the SIM it will still ask you to unlock that SIM card in another device). However, due to the nature of how Windows Mobile works your device would still be accesible, just not the network related tasks of calls and data. So I would recommend just using the Lock settings.
All SIM cards (unlike Windows Mobile) have a default PIN code as it can't be blank. Ask T-Mobile what it is (or it may be in the manual), but it generally is either 0000, 1111, or 1234. But don't try too many times as that will lock the SIM card and you will need a PUK code to unlock it.
Hey thanks for your reply, its pretty comprehensive and it worked for me. You were right, the options of the PIN under phone settings are :
1. For authentication at the time that the phone is starting up after a shut down or restart.
2. For SIM authentication.
But i was looking for locking my fone when i am not using it and as u said that feature is under the LOCK settings.
Thanks again for your input.
Sorry if there is a very obvious answer to this. I have a SIM lock on my simcard on my Desire so I have to input the PIN code when I switch it on. Occasionally, I get distracted and the SIM unlock keypad disappears before I put in the code. I have not found a way to get it back to input the code without switching the phone off and on again. Surely there's an easier way?
Just tested it on my phone, after the keyboard goes away I have the lock slider, and under the text "Drag down to enter PIN1 code"
Obviously dragging it down lets me enter the code.
You don't see the same screen?
Ah but I suppose my problem then is that I am running No Lock to avoid the lockscreen. I suppose there may not be another solution.
Reading this topic just reminded me to put a sim lock on my phone.
What is the initial SIM PIN when you have not set it yet?

Me too, just set my new PIN.
As for the initial PIN, it is 0000 for O2 UK but I think it is the same for other operators. You can always check it with your network operator.
1210 for T-Mobile UK, at least that's what mine was. Although it is an old one2one blue SIM.
I have an LG E900 I want to unlock, My carrier gave me the unlock code and told me to insert the new sim in and enter the code.
I put the SIM in and I get.
This SIM card can only be used on a specific network. Contact your customer service centre for the unlock code.
and below that I get a keypad however the keypad has no * or # which make up part of this code.
I have contacted Orange who sent me to LG and then LG sent me back to Orange.
Any ideas?
Sounds as if the phone has a Sim lock activated. This will prevent access to the phone functions until deactivated.

What you do is instert your the sim you want, then when you get a number/key pad enter the unlock code you get and wallah it works.
Hope that works, if you need more help pm me.
Just got a hold of a HTC One X and get no signal at all when I have my SIM in.
Was originally from O2 (UK) and when opening a SIM info app (eg SIM card, SIM manager) the SIM state shows as network locked.
I'm assuming the phone needs to be unlocked but there doesn't seem to be any way of inputting a unlock code (doesn't prompt for unlock code with SIM inserted,no option for entering unlock code in security menu).
Any ideas?
Thanks

Don't think you can SIM-unlock a HTC One X without s-off, unless you have a code, in which case ive read in some cases you may have to insert the new SIM code and hard reset the phone, to then input the code. But don't quote me.

Yea that's the thing though. I have an unlock code for it, I just can't find anywhere to input it.
I've done a hard reset and there's still no prompt for unlocking.
EDIT: my flatmate whose phone it is said that it was working fine before upgrading to JB.

"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.
