sim unlock - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

Hi, i bought At&t note 3 and i have someone brought it to Indonesia. The thing is, they forgot to insert the sim-card there.
I root the note 3 and tried the RegionLock away from chainfire but it doesn't work.
Is there any other workaround i can try? Does installing custom ROM will work?

No, the ROM has nothing to do with the SIM-lock. Someone (you or they) will have to buy an unlock code if AT&T won't give it to you. (They may, if the phone will permanently be used outside the US.)

RegionLock Away wasn't meant for unlocking your SIM, it was meant for getting rid of the region lock Samsung imposed on the phones.

[Q] SIM unlock

I might need to change service providers soon because Koodo is just sucking right now. As such, my phone needs to be unlocked. I would be paying Koodo for the service so that I don't have to run the risk of bricking my S5830D (can you even brick a phone while attempting to unlock it?). However, my little Ace is running CM9.1 RC4.1 by Wayland_ACE.
I don't know the SIM unlocking procedure and I was wondering if I would need to flash back Koodo's Stock ROM (where can I get that by the way?) and unroot it to have it unlocked.
I also heard of unlock codes around these forums and was wondering what they were, does Koodo just give me a code that I enter somewhere to SIM unlock? Please give me any information that you can on this matter.
Koodo charges $50 for this service, is there a simple safe and less expensive method to SIM unlock?
Thanks in advance.
I unlocked mine with an app from Google play called Galaxy Ace Unlock, by Helroz. You can find it HERE
It worked like a charm for me, if it doesn't find the code, install Busybox and try again.

Sounds good, I'll give it a try. Busybox is already installed with my ROM and any other installation fails. If it fails and I can't install Busybox, do you have any suggestions?
I found this: http://forum.xda-developers.com/showthread.php?t=1335548
Is there another easier method to unlocking the phone? this is a lot of work... -.-
With Busybox already in your ROM you should be good to go. The one I posted the link to worked for me so I never had to try any other method. I got 3 codes, and the second one worked. So, yeah, I really don't have any experience with other methods.

Brilliant worked I obtained the code (the same one repeated four times?) I will unlock it when I get the chance. Do you need to be on a stock ROM for the system to read the code?

I don't think so but try it and see... Generally if there's a message to say the phone is locked, there should also be an option to unlock it.

Quick Question 910A At&T Phone - Prepare for T-Mobile Rom - Unlocked Already!

My friend has a 910A At*T Note 4 - I unlocked it and her data, calls, pics, texts all work GREAT!
Now what else should I do to prepare it to get a T-Mobile Rom, as she is with T-Mobile and wants root and a custom rom on it
Thanks in advance - tried searching nothing much came up on this Topic.

To my knowledge there is no root nor anyway to unlock the bootloader.
The phone is locked down.
That is why people who wanted root bought the N910T from tmobile and use it on AT&T.
Sorry to burst your bubble.

I unlocked my AT&T Note 4 and am trying to use it with T-Mobile but it won't register on their network. I can't even make calls, I can only get numbers off of the sim card. Any ideas on what I could do?

Help!!! Samsung galaxy note 3 rooted trying to use different service.

Hi. I have a Samsung galaxy note 3 and it rooted. After the root I wanted a different service so I have t-moble. I downloaded the region lock away and went through the steps. After my phone was rebooted it still ask me for a unlock code after installing the region lock away. The note 3 is a att phone. Need help
What rom is on the phone? I believe region lock away will only work with certain modems.
I don't have safe strap installed with different roms. It's the original rom and the phone is rooted
If the rom is too new, I don't think region lock away will work. For example, the s4 the modem must be 4.2.2 with root before region lock away will sim unlock the phone.
Oh ok. Well I'm 5.1 android version. Is there another way I can do this instead of paying for an unlock code?
The only way to unlock would be to get an unlock code. If you're not on ATT and the phone is not blacklisted, maybe contact AT&T.

Root my S6 Active

Hi if I root my S6 Active will that also unlock it. No I know everyone is going to respond rooting and unlocking are different things but the question is if I root it will it still be network locked. Or does the act of installing new software on the device remove the network lock?

It won't SIM unlock it by rooting it, they're 2 different things. You need the SIM unlock code to use it on a network other than ATT.
Are you sure

Are you sure does that mean that the network lock is hardware on the device and not just software. I mean if I erase all the software and install a new custom ROM if the network lock is software based it should be gone. The reason that I ask is I just got my phone back from samsung for a repair and now I can't unlock it. AT&T and Samsun have no idea why the unlock code doesn't work. So I need to find a way to unlock it without AT&T's help.
Will fix it

thats unsual.....
Not sure I have ever heard that flashing a new rom would Unlock a phone to any sim before and indeed that would mean just reflashing a full stock rom on samsung devices would unlock them.....
In my opinion you probably talked to someone who had no idea what they was talking about and said what you wanted to hear..
I could be wrong but am sure MANY others will confirm what I have said...

Convert Verizon Note 9 to AT&T Note 9

Is it possible to convert via firmware update a Verizon sim unlocked N960U to fully branded AT&T N960U to get wifi calling and all the other branded features from AT&T? Right now I am using AT&T sim but when my device boots up it shows Verizon and all the Verizon stuff is there. Thoughts.....

Thanks I figured it out.
Just in case someone stumbles on this thread I will post the solution.
You will need to flash the US Unlocked version of the phone then flash which ever carrier you want.
Just for clarification purposes, are you saying that once you flash the ATT firmware onto a Verizon device that all ATT functions work? Or did you have to also provision the IMEI to achieve this as well.?

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

I am looking for the AT&T firmware. I am currently in Kuwait and destroyed my phone. I had to buy an unlocked Note 9 version with the exynos cpu. The problem is I can't WIFI call or use any of the Volte functions my other phone had. Does anyone have the firmware for AT&T? Will that only work with snapdragon? I have already rooted this phone and it is ready to go. I need these functions so I can call back to the States.

Thanks for the quick reply. It looks like I need to wait for Detonator to come out with the AT&T zip. It says coming soon so hopefully soon is in the next couple of weeks. That looks like the best route to go. This is the first phone I have ever rooted. I work with networks and sometimes software kicks me in the butt!

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

Thanks for the info. I read up on all of that and the trade off is worth it. I just need all the Volte features and hopefully the correct frequencies for the U.S. I had a note 3 forever and it got destroyed. I loved that phone. This Note 9 is awesome but without being able to manipulate the IMS settings it is a PITA. I just want to be able to call home from time to time. Emailing the wife is no fun especially with the tech available today. I will keep an eye out for Detonator to provide the AT&T CSCs and all that fun stuff. Then this phone will officially be outstanding. I do have to admit that the rooting process was fun. I am all about modified anything. Stock sucks. LOL

Im not a phone guru like others on here. But from my experience that is all I did. A really important step I didn't mention is leave the cable PLUGGED IN when you flash the unlocked software then the locked software. This caused my device to read the "sim info" and provision its self for ATT and get rid of the verizon stuff and install the ATT stuff. Hope this helps you out.
