I got an unlock code from AT&T, but I was never prompted to enter it after putting an H2O Wireless SIM card in my GS3. I'm able to place/receive calls and get data after entering APN settings.
My phone is rooted, but I didn't think it was already unlocked. Maybe I missed something. Any ideas? Thanks..

Did you buy the phone from someone else or an official retailer brand new in the box? If the former, someone may have already unlocked it. Otherwise did you perform the JB unlock method via the services menu?

I purchased the phone new from AT&T and rooted it a few days later. I never did the JB unlock.

Prepaid or postpaid... They all work as long as they are same phone service provider. Try a different network n see if that works.
Its a network lock, not a service/plan lock.

I guess that explains it, since H2O uses AT&T's network.

Hello,
I have a locked T-999 and I'm getting my hands on an unlock code. Can I buy any cheap microsim card to unlock my device or does it have to be AT&T?

I would think it'd need to be a tmobile sim, but I'm really not sure about that.

Any non T-Mobile SIM card will /should being up the unlock menu.

Insert any non T-Mobile micro SIM. You have to have a SIM that's not T-Mobile. T-Mobile s3 doesn't have access to unlock menu until another SIM is in the phone. At least it wasn't possible when I unlocked mine months ago

Thanks for the responses!
So I can just get this one (http://www.ebay.com/itm/NET10-MICRO...130794368103?pt=SIM_Cards&hash=item1e73f3ac67) and it is guaranteed to bring up the unlock menu?

or just go in to ATT and ask them to use one for a sec. Im sure if you tell them you need to unlock the phone to their network they will have no problem letting you use one for 30 sec.
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?

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

you have a Verizon S3, that is the FIRST place you need to go. always go to the forum for the device you have, bro.
http://forum.xda-developers.com/forumdisplay.php?f=1708
If I'm not mistaken, some Verizon devices will not work on US gsm networks even if unlocked, only foreign gsm networks.
Saw an article about this, although it might have been a different phone that was being discussed.

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.
I been at this for thee days now! so I bought a gnex from a friend that was using it on a plan with at&t. he now uses a prepaid plan with a different phone and sold me this galaxy nexus. now I did have a Motorola defy that I was using for tmobile but it has gon to crap so using a sim adaptor I placed it into this gnex but it wont pic up the tmobile network. when I go to settings phone info status it has my sim card phone number and all that, but it doesn't have network and all the other stuff. :crying:
so does anyone know how I can fix this or give me a walkthrough with using the unlock codes for Samsung galaxy nexus?
AT&T never sold a galaxy nexus. you already have an unlocked device. try doing a factory reset from the settings with your SIM card in it. Are you sure your sim adapter is fitting correctly?

How many different threads are you going to open for the same exact issue? You are breaking multiple forum rules right now.
Have you tried calling TMobile to see if there is anything they need to do on their end? There shouldn't be but you never know

My friend got a phone from T-Mobile s3 few weeks ago and unlocked it to use it here in Canada in mobilicity network. But it has like 0 reception it gets reception for few mins than goes to 0 bars. Is it a radio issue or something else? Any help would be greatly Appreciated. Thanks!

Are you sure the unlock was successful? Im not sure how it works in Canada but could it be blacklisted?

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.
and for some reason this is the newest s3 i think cause usually its t999v this one say t999l

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?
Sent from my SGH-T999 using Tapatalk
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.

I have bought a service to get an Unlock Code for my Samsung Galaxy S3 T999N which is SIM Locked by Metro PCS. They provided me with some 4 codes: NETWORK, PROVIDER, SUBPROVIDER, DEFREEZE.
When I turn on my phone with a non-metropcs sim, the phone prompts: "PIN to unlock SIM service provider" so I put the PROVIDER code that I got from FATSGSM after hitting "Unlock" I get the following message: "unable to unlock sim service provider"
What is wrong? Could the PIN provided by this service be wrong?
Just an FYI, I am outside the US right now.

This might not be true because if you have the Metro PCS sim card inside, you will not get the unlock box. You only get the box to put the unlock code in when you put a non-MetroPCS sim card.
Can anyone corroborate this information?

He means it may need to be activated with the carrier first in order to be unlocked.. Some phones do require this.. You can try the region unlock app but I'm not sure if it works with s3

I used it when I got my replacement S3 a while back and it said the unlock was successful. I have no way to test if it really was or if it also SIM unlocked though. I wouldnt expect it to do so, but in my experience, it is safe to try.
