why do u always think i didnt search? maybe for u it's easy to find but i cant find nothing about this. maybe u dont understand the question?
Unlocking sim has nothing to do with root. It's part of sim management, if you provide a correct code calculated with imei number and your phone provider it just unlock the sim card.
You have generally a hidden menu that doesn't need root to be able to enter the unlock code.
You can bypass this on s3 with some apk that need root.

why didn't you ask cingular when you called them??
i suppose if you insert a sim card from another company, a device will ask you for an unlock code.
Unlock Procedure
On devices I've used in the past:
Insert non-Cingular SIM into the device
Turn on device
Enter code when asked for it
Use unlocked device
If you don't have a non-Cingular SIM you wish to use you'll gain nothing from unlocking the device.

I called cingular and I got the same instructions that KOGIR posted So that should work.

I travel a lot internationally for work...does this mean you have to enter this code with each sim card?.
I know on my samsung t809...there are a unique sequence of buttons you enter to get into the maintance screen...this will unlock permanently.
I have a backup phone and I dont remember the PIN I used. I previously rooted the phone and installed an ICS ROM (plus a bunch of apps) so I dont want to wipe the phone and start over. Is there any way for me to bypass the PIN lock? I am hoping that since I rooted it this is possible!
Ask to your operator, from the phone side you can't do anything
What about this method? Has anyone been able to get it to work? Keep in mind that the old phone is rooted. I would rather not wipe the phone so I am hoping to find a good solution.

After 5 incorrect tries, I think the phone allows you to sign in with your Google Account

Do you mean you've locked the SIM card or the phone?
If it's the SIM card, you need to speak to the provider to get a PUK code
If it's the phone, you can unlock it by logging in with your Google account after 5 attempts as posted above

Not the SIM, just the PIN code for the phone itself.
My question is why there is no software that can sim unlock xperia x10, i mean access has been obtained to the bootloader and everything inside, i dont understand why there is no method to sim unlock this cellphone, other android cellphones that are succesfully rooted and hacked their bootloader are super easy to sim unlock just one button press like samsung galaxy so my question is why cant they acess the area where the lock is stored and erase it or replace it with an unlocked register, im really interested in this info, if someone answers me or points me in the right direction it would be really appreciated, im pretty sure there is no method and i want to create one, probably imposibly difficult but i want to try.

I dont have a technical answer to why its not possible but yes the answe is no. Theres no possible way to sim unlock your phone.
Galaxy phone capable of being unlocked already have the unlock code hidden in some file which we dont have.

Oh thanks i didnt know that about the galaxy but i still want a more technical answer about how can we have access to everything from bootloader, kernel, rom everything, so where is the sim lock hiding?
How do I get my S3 to auto prompt for the unlock code? I'm just trying to unlock it for use on another network, and maybe apply a new ROM (I tried Android Revolution HD which looks cool)
I have the stock Vodafone UK ROM on it right now, but can put another ROM on it if I need to do that to unlock it.
It used to prompt me to enter an unlock code, but now it doesnt...
Thanks,
Paul
If you are talking about a pin for the SIM, then this is stored on the SIM so will not take effect if you change sims. If you are referring to the unlock specified in phone security settings, then this will get removed when you wipe the phone (such as when you put on a new rom).Just go back into settings and set the unlock code again.

Hi,
To have the asked unlock code, just put a SIM card from another carrier. You are on Vodafone so put an Orange SIM card (for example) and you will have the unlock code request (I presume you have it?).
But for move to another ROM you need to unlock your phone?
Or try this to unlock your phone: http://forum.xda-developers.com/showthread.php?t=1846451&highlight=sim+unlock

I mean the unlock code to use on a differ t network. It should ask for unlock code when I put in foreign sim.
Where us that option in the settings?
Thanks,
Paul
Yes if it doesn't ask, maybe it's already unlocked.

Thanks Viking37...
I have just used the GalaxSIm unlock and it's worked a treat so I'm using my Orange SIM... I expect that the O2 SIM may not be setup by O2 yet. I will have to call them to get that SIM sorted out.
Thanks for your help. This is now solved.

I bought a sgh-t399n at a garage sale recently and quickly rooted the phone and installed TWRP Recovery and CM12 on it. I called Metro and T-Mobile ( After flashing their firmware) for the unlock code but of course they refused to give it to me. So i tried 2 or 3 different unlock by IMEI websites as well as every single unlock app and software I could find while running logcat. The best lead I've gotten was the S.G.S. Unlock Tool app. It says it found the code but the results are null. In the logcat the system denies permission saying that the app was sending request as -2 when it was 0 and that it needed "android.permission.INTERACT_ACROSS_USERS_FULL" to accsess the info. Now I'm not a Dev by any definition of the term, nor am I any kind of hacker but I have learned a good bit from these forums over the last couple of years and my gut tells me this can be done with a little patients and some help from the good folks at XDA. Any imput on the subject is greatly appreciated.
You won't be able to unlock on CM12, have to have the stock firmware and OS installed.
yeah install stock system and any code should work without issue
If you unlock on stock system and then flash cyanogen, will it be fine?

The unlock code must be hidden on one of the partitions of the device it's self though right? Possibly in the EFS partion? Also how would i change thepermissions of an app to allow in to interact acroo all users?
Whether or not the code is in EFS, you still can't unlock on CM.
No I understand that. It is currently on the T-Mobile stock T399 firmware flashed with odin but still could not get an unlock code . Also i would like to learn to unlock these phones for future devices.
So it is not requesting an unlock code when you have a non T-Mobile SIM card installed? How odd... It should. If not, either it's already unlocked, or something else is going on. Have you tried both the Metro and Tmo firmware? Only the newest T-Mobile and Metro phones are not supported by unlocking via code as they use the Unlock app. As far as unlocking yourself, your best bet would be to get an unlock box like z3x or Octopus if you plan on doing a lot of them. If it's just 1 every year or 2, then it wouldn't make sense. Some phones have ways to unlock via root and hacks, but not all and it is becoming less common now as more manufacturers are making the ways to unlock more difficult either via encryption or other means.
The unlock companies I tried were unable to get a code by imei. Therefore I was never able to put in a real code. I've looked in to the z3x but it is way outta my price range as I am only a novice tinker. I just figured since the code must be in the programing of the phone somewhere then it was just a matter of locating the partition and file in which it was hidden and then decoding it. Is it possible to change an apps or users permissions? If so how?

I believe the app Root explorer allows you to change permissions on items.
It does, but nothing Root Explorer can do will help you find an unlock code, unfortunately. If the phone does not ask for a code when inserting another carrier's SIM, then that's the issue that would need to be resolved before anything else.
Sorry if I've been unclear. The phone dose ask for a code when a sim from a different carrier is put in but after trying 3 unlock by IMEI companies none of them were able to generate a code by IMEI. As for the permissions issue, I have an app that claims to find the codes but only says "null" in the results column. After going through the log cat it says the app is running as user 0 but is requesting info as user -2 and that it needs the permission " INTERACT_ACROSS_USERS_FULL" to show the info. So i was hoping to learn how i grant said app that permission and see if it would show the code?

Could anyone PLEASE PLEASE PLEASE PLEASE PLEASE give me a working unlock code for my metro pcs phone email me [email protected] or [email protected] thank you.
Running into the same problem only im on a non rooted system. I need a solution to get the codes needed to unlock it from T-mobile and need them without running hardware as all i have is hardware from the old days. Software would be a choice if anyone knows of anything reliable. Services I am also willing to pay for if cheap and working.
