Hello,
I bought a Captivate in USA, the cell works fine in my country (Chile). I want to install a customrom, but I don't know if it's possible considerating the problem of the Sim.
I appreciated if you help me
Thanks

Hi, i bought a factory unlocked captivate from USA and never had a problem with custom roms. The sim never got relocked and i had flash over 20 roms on my phone. And i live in Argentina, without any access to an AT&T sim.
Though i would suggest, that you try to get your unlock code written down somewhere before you do custom roms, specially if you did not buy it factory unlocked. There is an app that gets the unlock code for you, I can't recall its name. Some of the phones get relocked after going back to stock; though I'm not sure if it is because they where manually unlocked instead of factory unlocked. What I do know is that when i tried to get my unlock code it wasn't anywhere, so I started flashing the phone hoping it didn't get sim locked.
If you don't get the code, flash and get sim locked there are several posts that explain how to unlock your phone. Those and the "universal sim unlock" gave me some peace of mind at the time.
Thanks!

Back up your efs directory. It is possible to relock and be stuck if you don't. There is no factory unlock captivate. All are att and have to be unlocked via code.

Hi,
First of all I hope this has not been covered, I searched but found nothing.
I recently bought an unlocked Captivate from the US, I am in Australia. I put my sim in and all was good. Used it for about 4 weeks and then one day turned it on and said on the screen 'you have entered an incorrect unlock code, please contact service provider.'
Now I never entered a code or even had a chance to enter a code. Now it will not let me use any sim at all or even give me a chance to enter and unlock code, which I have obtained using the one click unlock found in this forum.
The phone is rooted but was working fine when rooted originally.
Can someone help? I can still use phone with wifi just not sim. I have tried a hard reset and that still has the same problem. I have tried flashing it back to an older rom, same deal.
What can I do? I can't even enter an unlock code to get it unlocked.
All sim based devices have a PUK code...contact your provider, ask for it and then try to unlock your phone till it ask for it...then you can reset it...that'd what I would do.

hey, I tried to unlock this cell phone (SGH-T679) for few days now
but I failed to unlock it
it's really tough to unlock it i guess
Tried using several unlock Apps from android market but they didnt work ;(
and I even bought a code from a website but it didnt work either lol
nah.. can someone please help me out to unlock this phone?
it is originally from T-mobile but now i'm using Fido (in canada) ... so have to unlock it ASAP
If the phone is from T-Mobile, and you are using it successfully on another carrier, then it is already SIM unlocked.
Hi all,
Not got the G yet but looking to get one for my sister from Tescos as soon as I can. I see root is now resolved via "superroot", I see that people are getting SIM unlock codes from eBay etc. All good.
I see a lot of talk about flashing the factory rom over the Tesco one - but see many ifs/buts/maybes. Has this 100% been done by anyone?
Finally - if bootloader is unlocked, factory rom installed do I actually need to get a SIM unlock code too? (I would have hoped that would be enough but looking for confirmation from those that know!)
Cheers
Chris

If you want to use a different network other than tesco you will need to obtain an unlock code, unlocking the bootloader and flashing roms will not unlock the device to use other networks
Cheers for the info. Fair do's I guess....

Hi everyone. I bought a T-Mobile's Z3 used by another guy. He shipped it from the U.S but i'm not there. The thing is: He bought a SIM unlock code but T-Mobile won't let me introduce it because they only let you unlock the phone through their app. The question: If I debrand the phone by flashing the global/international firmware would it let me introduce the code? . I hope you can help me.
I don't think you can just cross flash, at least that is my experience with other devices as well. Also no way to bypass the SIM lock as there is no boot-loader unlock or r oot for the TMO Z3.
As far as I know its an over the air unlock and there is no option to even enter a code... when the app did not work for me I called TMO and they unlocked it within an hour, as I am a current customer.

Oh well!. So the only hope is to wait for some root method. Thanks for your answer :good:

Root and bootloader unlock have no effect on sim unlock. They are completely different things
It depends by phone/carrier implementation I guess, for my Sprint LG G2 you could bypass the simblock using a method that requires root. In the HTC M8, boot loader unlock with Super CID could achieve SIM unlock as well.
You probably are correct with Z3 though.
Im in the same boat, bought a used z3 and tried to unlock using device unlock app on phone, Failed. I bought an unlock code but there is no menu to input unlock code. If we flash global generic firmware, will unlock code pop up?

Has anyone tried this and been successful? I attempted it this morning but got errors and flash aborted.
Edit
Guys keep trying the unlock app. I almost gave up and tried it one more time after a factory reset. Went through the setup menus. No Sim card, WiFi through my old Xperia z, turned on my location. Opened the unlock app and applied for permanent unlock and BOOM.... Unlocked.
Don't know if any of what I did made a difference but try it if you want.
Best of luck to you all.

Okay. I have att and the note 5 is tmo and unlocked. If I use Odin for any reason, even to revert to 5.1.1 will it no longer be sim unlocked?
Sim unlock has nothing to do with Odin, rooting, or installing custom roms. Once it's sim unlocked it stays sim unlocked.

You are right, nothing to do with software, firmware
or odin.
-------------------------------------------------------------------
But...
There is no reason to use a sim-unlock service since
anyone can unlock their N920T or S6 Edge/Edge+
with the tmobile device unlock app which comes with
the official stock firmware in the phone which can be
also downloaded from Tmobile or the playstore.
The only requirement is that the phone is paid off
and you have owned the phone for at least 30 days.
If those two requirements are met the Tmobile device
unlock app will ask you if you want a temporary or a or
a permanent full sim unlock.
It will not ask for any other information or input.
The Tmobile device unlock app can be downloaded
from the play store.
Here is the playstore download link:
https://play.google.com/store/apps/details?id=com.tmobile.simlock&hl=en
Good luck,
Have a great day!
