Network Unlock your ATT SGS3 for free (howto) - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I just saw this on Reddit and tried it on my ATT SGS3. I used an old StarHub SIM I had laying around and it didn't ask for the unlock code, so I'm pretty sure it worked.
The instructions are for the GSM Note 2, but the author says it works for the GSM SGS3, too.

I think you have to be on a stock ROM to get it to work. I was running UCALH9, bone stock. Don't forget to thank the OP on the other thread!

It doesn't work on TELUS SGS3 :/

I don't know. Since the SIM I had laying around was not a mini-SIM I had to chop it up, too. O_O
In theory you don't ever see the unlock prompt unless you insert a non-network SIM anyway, so I don't think there's any way to check without one.

Same here. I tried all the steps, but when I got to "now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ", I didn't have the "[4] NW Lock NV Data INITIALLIZ" option, just the original 3 choices.

Tried two different Bell phones.....same outcome.

If you are in the US with AT&T just call AT&T and tell them you are traveling abroad. You'll get the code right away. I chatted with support with a 2-week old SIII and got it right away.

you might need to update your modem/baseband for this to work. i upgraded the modem and then these steps worked just fine. (from LG1 to LH9 on att)

Works on Bell GS3 after 4.1.1 OTA
I also confirm this works after installing the Bell 4.1.1 OTA. This is likely due to the new modem version. Tested with a cut rogers sim.

to be fair, everyone posting this doesn't work for them is not on AT&T as the OP posted this for

Question. How do you know if your phone is unlocked? I tried this on Serenity 1.2 with LH9 modem installed and I was able to insert a SIM card that I used when I was overseas. Does that mean I'm unlocked?
Nvm, my international SIM picked up T-Mobile while roaming... even though I don't have roaming enabled ><

If your carrier is AT&T, i'd have to say that just going onto their web chat and asking the rep that you talk to if you could get the unlock code for your phone is probably the easier method. I did that about a month after i got my phone, on contract, telling them that i'd like to have my phone unlocked should something happen where i need to use the phone on another carrier. Didn't work with the first person i talked to, but the second person got me my unlock code.
You didn't search hard enough or at all.....

has anyone tried this the other way around? I just followed the steps on my tmobile s3 but I can't verify since I don't have an att sim.
worked perfectly for me on bell , and I tested a telus sim and it worked perfectly!
Confirming that it works. Also, it's not that difficult. I did it in about 5 minutes.

Works as long as

2) your baseband is before ALL4 (for tmobile)
And you are correct there are about 5 threads in this section, and probably the same number in each other note 2 forum.

Yes, it does work with AT&T and any other Sim cards. It is completely unlock
just like using the code from T-mo.
However, you HAVE to be on UVALK8 or lower for this method to work.
It will NOT work with LL4, as they patch the "hole".
This method is some months old and from time to time somebody resurface it, but that is not bad as people tend to forget.

Data issue...

Ok SO I could not find a proper thread for this since there are SO many threads. The issue I'm having is I got a Samsung galaxy S III that was unlocked, and after I put my ATT sim into it I could recieve texts and calls but I could not recieve data. So I rooted it and applied clockwork with all my mods and figured I could find some setting that would fix it... well I was wrong. I tried global, GSM and LTE settings none of which would give me data. If there is anything anyone can do to help I would be more than appreciative.

While I agree that you should always call at&t so they can register a device to your account, this will not help his current data issue
OP, is this an international s3, T-Mobile or at&t? What firmware/rom is installed? Again, verify your imei is intact
Ok so this is a verizon Galaxy S3. It is rooted running 4.1.2 JB, Kernal 3.0.31. After I got the phone I did go to an ATT store to register a micro sim because i didn't have one at the time. So the imei is registered to my sim card perfectly. I can get calls and texts without any issue but no data. How do I figure out what the apn settings are and if I have the right configuration?

You do realize you're trying to use a cdma phone (verizon) on a gsm network (at&t), right? Different radios. Different technology. Won't work
Well it was unlocked at the phone has a gsm option so if it wasn't compatable I don't see why they would have the option there to actually use a gsm network.

You need to read more.
this phone only supports GSM with EDGE data.* This essentially means that you'll get 2G data speeds (unless you have a WiFi connection) because it doesn't support UMTS/HSPA+ which is required for international and U.S. 3G data. the 4G LTE frequency supported by this phone is only used in the U.S.* For those who don't know UMTS/HSPA+ is the 3G technology used by GSM carriers internationally (and used by AT&T and T-Mobile in the U.S.) which is different from the CDMA/EV-DO 3G technology used by Verizon and Sprint.*
This phone IS unlocked, that part is correct. But only for gsm carriers
So its preventing me from recieving ANY form of data possible?? It is a Verizon phone and I have ATT so you mean it doesn't support GSM then right?
Sent from my SCH-I535
You're in an at&t s3 forum with a verizon s3 that has zero data. If you really want to pursue this issue, you should start looking around in the Verizon S3 forums

If you are going to stick with AT&T, that is the way to go if you want to have data. No worries. Stupidity is only if you didn't learn anything. You had ignorance of the situation and now your don't. Do some research on any phone before you buy next time (especially if branded from another carrier). This can save you a lot of headaches as you have just learned. Just remember some basics from this forum. Good luck.

[Q] Note 2 Big Issue - PLEASE HELP!!!

Sorry I m a Beginner in the android world, so i will do my best to explain my issue
Please help me all help needed
1) I bought a Galaxy Note 2 from a person - he said that Note 2 was BLOCKED by T-mobile - I verified with T-mobile and the IMEI is indeed theirs and it is BLOCKED - so we know this is a REAL phone, NOT a clone
2) when I bought it he said that the phone was unlocked and is being used on AT&T - I verified and saw that he was using on AT&T network before he Reset everything and gave to me.
3) i went home and put in my AT&T sim and the screen read "Sim Network Unlock Pin" with Unlock and Dismiss button below. I thought this was the sim lock, so i removed the sim lock, but it still show that on the start screen - so here I thought that the Phone Might have been Un-Unlocked due to Reset.
4) I went ahead and follow the direction on how to unlock S3/Note 2 from XDA (http://forum.xda-developers.com/showthread.php?t=2014982), - btw i did this Successfully on 2 S3 before. Here is another problem: Under Lock Network screen (option 6) I cannot see option 4: [4] NW Lock NV Data INITIALLIZ (Does not exist) - So I have no way of unlocking it since this option is not available.
5) I thought that he did somekind of custom rom, but no - i checked and the Binary counter is 0 - phone status is Normal.
Please help me.
All I want is to use ATT now.
Please help me I will stay all Night till this is solved.
Thanks all in advance.
BTW attached is my About screen in case anyone have question.
*** second issue that we will talk later is - i have another note 2 bought directly from t-mobile with 4.1.2 - this one does not have [4] NW Lock NV Data INITIALLIZ . either. - how weird.
I check at the store and their note 2 4.1.2 HAS that option. !!! - we shall talk about this issue at another time

No, i dont think they share blacklist. When i bought the phone it clearly showed att and use normally, then i took his sim out and reset the phone and brought it home. Test with T-mobile sim right away (i have both tmobile and ATT) - t-mobile say SEARCHING.... it is block so could not find any net work, but when i pop in at&T it said "Sim unlock pin"
Also the reason y i know t-mobile and att don't share the same black list is because i used a blocked s3 on att before

hi,
i did some research and i think T-mobile and AT&T will potentially share the blacklist - but don't know it worked on my s3 before.
I just came up with an IDEA and would like to hear from Pros see if it will work.
What is if Install Samsung ROM - but the international version (usually my t-mobile i would download tar.md5 from t-mobile, same for att). What would happen to my phone if i download and install International rom - would it make my note 2 INTERNATIONAL - that mean it is NOT lock to any carrier?

Stay clear from blacklisted phones. Solves this issue
I hope that blacklisted s3 was not the phone someone stole from me.. I would never buy a Black listed phone. I do know all of them are not blacklisted because reported stolen. But if you take the ability to sell them People will STOP STEALING THEM..
Just as a quick note. In The future it might be best to not Buy blacklisted or bad imei Phones.. Some are from contracts not fulfilled .. Questionable as to rather a carrier should be able to black list or not..
But equally number of them are STOLEN. What if it were your phone.
I so was not going to write this post . But it It really much different then software piracy or buying Stolen goods...
Just my opinion.. Ohh and yes i think the carriers are evil in near every way.
Good Luck and hope you get it fixed but only if it was not a Stolen phone. if it were . Well my above comment will tell you my thoughts.
Is there a way for you to talk to that person and ask him where he got the phone from? i hope this gets resolved ASAP
Hello all
Thanks for helping.
Indeed i have downgraded to 4.1.1 and now have 4 option and was able to unlock it for AT&T
However, i have a silly question that i hope to find a RIGHT answer.
I know that we can do Custom Rom for note 2 - however, I was wondering if we can install ATT OEM Rom to T-mobile note2, or T-mobile OEM Rom to AT&T note 2?
DOnt know if i made it clear enough.
Please help.
Thanks

Yes unlock was successful and recognize the network. Gets reception you can make call after few mins loses it and goes to 0 it's not blacklisted as it was purchased outright from the retail store. Right now there is no Sim card on phone and it shows 4 bars.

Yes unlock was successful and recognize the network. Gets reception you can make call after few mins loses it and goes to 0 it's not blacklisted as it was purchased outright from the retail store. Right now there is no Sim card on phone and it shows 4 bars.

Are you sure the unlock was successful? Im not sure how it works in Canada but could it be blacklisted?
While it shows signal does it work for calls and data?

You might need a new sim card. And the T999V is only sold by the Canadian carriers. The T999L is the updated lte model of the original T999.
After unlocking were you able to use a sim from another carrier and have it work with zero issues? If you only tested it on the network you are reporting problems with that is not confirmation of a successful unlock. Try a sim from another carrier and see if it works.
If it is unlocked then it sounds like an old sim card type issue.

just tried my sim card same issue and we tried with 2 other brand new sim card from ssame provider. i just flashed this March 2014 - 4.3 JellyBean - New!
Note: This is based off of the stock image TMO T999LUVUBNC1
Download :: Download - root66_TMO-L_T999LUVUBNC1.7z through odin thought it might be radio issue but same thing.
her daughter has the same s3 with 4.1.2 and works perfect. can i downgrade through odin to 4.1.2? i think md5 modem might be better.
Unfortunately no. Once you flash 4.3 there is no going back. If its not working with any of the sim cards, try one from another carrier if possible.
Kinda sounds to me like its not unlocked. How did you go about attempting to get it unlocked?

She will come to pick the phone today I'll ask how did she unlock the phone. But if it wasnt unlocked how does it recognize the Sim? Can you suggest me a modem? But I will ask how she unlock it and let you know. Also when I flash the new 4.3 it didn't erase the call history and also when I reset the phone it doesn't seem like it resets it cause the call history's are still there.

You can only use the 4.3 modems now. When you flash firmware it doesnt erase your data. Not sure why it didnt on a factory reset though, unless its stored on sd.
