Hello, I am new here...
Help!!!,
I've bought a Cingular hw6920 and I would like to use it when I travel, with local SIM cards.
The phone is obviously locked and when I try to use another SIM, it shows the message "Network is locked, please input unlock code".
Since I have a Cingular account, I've asked for the code, but after sending them the IMEI (correct), they have replied that they cannot find it!
Same thing happened when I've tried to get the code through one of the pay services.
Any suggestion? I can't return or exchange the phone since I left it to my brother in Europe.
The phone has never been turned on in the US with a Cingular SIM, could this be the problem?
Thanks
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.
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.
This is for ATT Galaxy Note II model SGH-I317:
This little note is to provide clarity and ease to find out what carrier your SIM card is receiving after you have unlocked it.
1)You have removed your "normal" carrier SIM card
2) You have put in a "test" SIM from another compatible carrier
3) You entered an unlock code, with the "test" SIM in your phone.
4) Nobody can easily tell you how to check if you unlocked the phone properly or you were ripped off by the "unlock service"
THIS HOW YOU CHECK:
5)Make sure the "test" SIM card (the "test" is not your normal carrier and just used to ask for an unlock code) is still in the phone.
6)GOTO System Settings
7)GOTO More Settings
8)GOTO Mobile Networks
9)GOTO Access Point Names
10)OBSERVE...the current carrier. (IT SHOULD BE THE CARRIER OF THE "test" SIM, not your "normal" carrier.)
FINISHED.

......really?
Nobody can tell if sim is working? Lol.
If you have data..then unlocked worked. Pretty easy to tell.

What happens,if your "test" SIM is deactivated & you need to verify the carrier?
Thank you for the insight:
I posted, for those of us who have secured a legally deactivated "test" SIM card to unlock the phone, with no way to verify using an activated SIM.
(Now that is a very smart move on my part...obtaining a deactivated SIM to use in unlocking the phone instead of an active one)
Nobody wants to get off a plane and insert a "local" foreign pre-paid SIM and find out they did not unlock it properly.
I unlocked my SGH-I317 by obtaining an unlock code from ATT using a deactivated T-Mobile "test" SIM.
I am sharing this information for those of us, who are not developers.
REMEMBER: Fill another person's bucket, never knock it over. If you knock it over, karma catches up.
Another way I've used is to drop by another carrier's kiosk when they're not too busy and ask to borrow one of their demo SIMs for a quick test. (e.g. you've just done the AWS mod and want to know if it worked.)
