hi everyone:
I have been looking via numerous thread online on many Android forums especially here and have been unsuccessful for the past 2 days now. So I figured I would need to create a thread and finally give in and ask for some help. I have a T-Mobile Samsung Galaxy 3 phone and I need to unlock it so that it will work on my AT&T service. Now i understand about rooting the phone and being able to play with themes etc, but its not that great if I can't use the phone itself.
Now without coming up with some kind of answer I must have watched about 40 youtube video's hoping to find out some kind of information. Mostly what I got out of it was numerous website that offer unlocking for phones at a certain price.
unlockcodesource(.)com
unlock2go(.)com
mobileunlockcodes(.)co.uk
Has anyone ever used any of these website or can someone give me some good advise on how I can get this phone unlocked please/

I think the toolkit stickied in the development forum has an option to SIM unlock the GS3. I have not tried this, and do not know if it works, but if the option is there, you might want to give it a shot.
If you're on contract with t mobile and your account is in good standing with them. Call them tell them you're going over seas and need to unlock your phone so you can use it. They will send you unlock code ... then pop in an att sim card and it will prompt you to enter the unlock code t Mobil gave you. Done

OK thank you. I followed your instructions and they said it would take up to maybe 24 hrs for the phone to be unlocked. If it isn't unlocked than she said to call back with the conformation number she gave me. If that doesn't work than they would have to give Samsung my info and could take up to 14 days. She said when you buy phones almost all stands and corp stores have already unlocked phones.
she also said it would be auto unlocked for good. Can they lock the phone back up once it is be unlocked?

edited: Once I have it unlocked ( if all goes good ) do i use the same APN settings that I needed to put into the phone in order for my phone to work on the AT&T network as I did with my S2 that I got unlocked ?
Don't they use different frequencies for HSPA+
You would be relegated to edge speeds, correct me if I'm wrong

I really don't know. That would be a great question if someone would be nice enough to help me with this information? Again i have a T mobile S3 hopefully its unlocked would I be losing speeds by being on the AT&T network?
thanks

The T-Mobile S3 has the 850/1900 3G bands so it will work on AT&T's 3G network. It will not get LTE though.
You can unlock either by paying for a code from the various resellers online or requesting an unlock code from T-Mobile if you have an account in good standing with them. If you can't get the code from T-Mobile I suggest searching 'T999 unlock' on eBay and you'll find some good options.
The tmobile galaxy s3 will work on the ATnT HSPA+21 frequency. Same frequency the International version runs on for that network.

Edge network and 3/4G Question
I found an excellent place so far on eBay for buying unlock codes. they have almost 3800 sells with a 99% positive feedback. Great customer service. The guy answered numerous questions of mine and made sure i did everything correctly. Payment was $24.95 US, so hopefullly everything will go good.
He was talking about being on something called an " Edge " network which is a little slower, but he said you won't notice a difference between your unlocked S2 and the unlocked S3 now. Right now my S2 says I have 3G service when I use it. I dont understand how i had a inspire4G, what is the 4G for if AT&T only gives you 3G service? And where I am in United States I should have 4G service no matter what. I'm confused on that.,

Edge is 2G speeds, which are substantially slower than 3G speeds. IMHO, 3G speeds are livable, 2G/Edge is not.
Different phones have different radios which work on different frequencies. Some phones are not compatible with other services at all, and some will work on other carriers but often not at optimal speeds.

So than why would someone suggest that I would get "edge" instead of what i have now? I'm getting 3G now with my T-Mobile S2 unlocked on AT&T, but now I'm going to have an unlocked S3, why wouldn't it be the same?
Because the radios in the devices are different.

Because he/she doesn't know what he/she is talking about. You will be fine with a T-Mobile S3 on AT&T.
That's what I said earlier in not so many words.
Voice willl work fine you will not see HSPA+ speeds on At&t with a T-Mobile Galaxy SIII.
If the T-Mobile SIII has the hardware capability to support the At&t HSPA+ bands you would need modified radio software to unlock this ability.
I believe this was done on the Galaxy Note to tun on T-Mobile HSPA+ network before it was officially launched on T-Mobile.
kmdub I believe your the one that's wrong.

I unlocked my t999 and am using an att straight talk sim getting HSPA speeds. Going to switch back to tmobile prepay because it is way faster than att HSPA with better latency. Although coverage may be lacking, i may just switch to an att ST sim.
To answer your question, a Tmobile S3 will work on ATT HSPA+ network with the HSPA+ Speeds of up to 6-7mbps in NYC area. The average I've been getting is around 2-3.5 mbps. With the tmobile prepay sim I have, it's usually around 2-18mbps down in NYC area.
The T-mobile S3 will not work on the ATT LTE network because it lacks that radio (or so they say for now); there have been other threads suspecting it's just a matter of flashing the right radio to "turn on" the ATT LTE radio. However, if all you want is HSPA+ speeds, rest assured it will work fine.
The ATT S3 is lacking the AWS bands for TMobile so it will not get the HSPA+ on Tmobile.
Best regards.
radio issue
First off, I would like to thank everyone who has been helping me along with my issues with my phone. I appreciate it a lot and I'm picking up more knowledge more and more everyday from you guys and reading heavily on the forums.
if the hardware in the phone doesn't support HSPA+ 1) will i have to root the phone and 2) change the radio? And 3 ) if I change the radio does that mean I would need to install a custom ROM i order for it to work properly?
Also, from one of the post they said "The T-Mobile S3 has the 850/1900 3G bands " - of that is true will than I should be able to have the 3G speeds correct?
I really hope I am not making some people angry, I'm new to this and trying my hardest to understand everything so I don't make mistakes. Please bare with me. Again, thank you so much everyone who has contributed so far. I still have a lot to learn. The reason why is because I just don't want it to work ( I do, want it to work ) but I want to understand why everything is working they way it is and I've over the past almost month have been picking up a lot of knowledge. Can't wait to hear from you guys
kmdub I believe your the one that's wrong.

No, actually, you are wrong. The T-Mobile S3 does not need any modification to work properly on AT&T's HSPA network. Seems you are confusing something else with frequency. Quit spreading bad information.
OP: Don't worry about it. Some are making this way more complicated than it needs to be. As said before, if you have the T999, you will be fine on AT&T's HSPA network without any modifications (other than an account...lol). Just get the phone SIM-unlocked, pop in the right SIM, you are good to go. Seriously, it is that easy.
Well there it is, I stand corrected!
I had no idea the T-Mobile SIII supports At&t HSPA+ bands.
Is the same true to all T-Mobile HSPA+ phones?
Sorry for any issues, just learning
Hi everyone,
thanks so much for the info. Will the S2 I needed to put in certain APN settings inorder to receive MMS ( picture ) via texts. Do i use the same settings for the Samsung Galaxy 3?

I too have learned from this thread
After a pretty serious amount of searching, I still haven't been able to find a straightforward explanation of what works on which Note 2 on which network as far as 3G/4G service goes. (There was only one that came close, and it still didn't seem to actually be complete.) While the consensus seems to be that the T-Mo phone is the most flexible, what I've been able to cobble together is that the answer is much closer to "depends on what you want to use it for." (Duh, right?) So here's what I understand so far -- please feel free to correct me if I have any of this wrong, and I'll update (or if you think carriers/devices should be added to the list, comment with sources and I'll add on the info):
----
T-Mo T889 (stock unlocked): up to 42 MBps DC-HSPA+ on T-Mobile network (1900MHz); up to HSPA on AT&T network (trying to verify)
AT&T i317 (stock, unlocked): LTE on 700MHz on AT&T network (and future AWS when AT&T gets around to deploying); EDGE on T-Mobile network
T889 with T-Mo LTE unlock (est. Spring 2013): may possibly also enable LTE on AT&T network.
T889 with flashed AT&T radio (or NV partition edit): unknown -- no success to date. Hypothesized that it may enable LTE on AT&T network.
i317 with flashed T889 radio (or NV partition edit): loses AT&T LTE capability; gains HSPA+ (non-DC) on T-Mobile network (DC yet to be verified?)
No idea as to what would happen if/when an i317 can be flashed with a post-Spring 2013 T-Mo radio.
----
So the conclusions I seem to draw from this are:
If you want guaranteed highest speeds out of either service today, and some possibility of T-Mo LTE support in the future, get the AT&T phone and get used to playing around with radio swaps.
If you want the guaranteed highest speed out of T-Mo in a few months (and now, obviously), and some possibility of getting the highest speed out of AT&T (aka LTE) whenever xda-developers' ingenuity figures it out, get the T-Mo phone.
How does this sound to you guys?
Bewn looking into the same thing looks as the t889 should somehow be able to get lte on att but still cant find how

Short answer, AT&T Note 2 can get full speed HSPA+ on T-Mobile and LTE on AT&T... I currently have it that way... You need to activate AWS bands on NV partition... I also have the T889 and the T889 can do the same... Remember what I have been telling since day 1... They are both the same phone... Just with different signals pre activated by their respective carriers...

As I understand it the note 2 is the first phone to have all the different model have the same physical design and the software is very close to the same as well. I beleive that there are two internatinal ones the gsm and lte. All the us versions are based off the lte one so they are all very similar. I think we even have a few roms in the dev section now that are based off sprints rom. I could be wrong though. I was a little confused at first because usually on tmo our phone would be based off the gsm interntinal but not this time.
I gotta say I am really happy with samsung. And I am impressed with what they have accomplished with this phone and the sgs3. They told the carriers to go to hell and did it their way this time. I think they were able to do it because android is like 60% of the worlds cell phone market and samsung is like 75% of android sales. I am sure the numbers are off but I remember reading about that last year. Sorry to go off topic a little bit.

Uh, that's his point. And mine, for that matter. AT&T only so far - meaning my OP is currently correct. Nobody has done it on T-Mo (at least that has reported it here). "Hardware is the same," yeah, we all know that, but we also know the software isn't, so it's a matter of what we've actually tried and succeeded with and have confirmation of.
When somebody actually reports a success with T-Mo they can confirm, I'll update.

Sorry, poor assumption on your part. I found that. Did you read past the first post? First post says DC works (which was an edit, apparently yesterday) but post 3 says it only indicates DC, no actual speed bump to DC or 42 speeds. Lots of failures on that thread too. So I listed what worked for the OP. If you'd like to confirm dual-5MHz operation (which you didn't explicitly when you posted your success in that post), maybe some screenshots of the speed change if you have them, that should be fine and I'll edit.

Posts like yours aren't much better than trolling. What did it add to the conversation? Search for what?
If you'd actually searched and read the numerous threads across both the i317 and T889 forums, including both the General and Q&A sections, like I have, you'd see multiple claims of it works, or it doesn't work, and varying methods described with people saying they work and don't work. TEKHD has bounced back and forth multiple times on this, along with a few others.
I was just asking for clarification that this was done on a T889 or not, since TEKHD said in the post I was replying to that it does, but in the thread he linked he said it didn't.
This is a T889 forum, isn't it? What do the users of the T889 care about an i317 hack unless the same hack will work for us?
LTE on T889 Phone
Searched and found conflicting repoerts. Is it possible to get the LTE working on AT&T using the Tmobile T889 model of the note 2?
It is thought so, but no one's done it yet.

Ah ok... so i just got ATT today and am using it on my tmobile note 2. DO I need to do anything at all to be getting the best speeds or is it getting the fastest it can right now until someone gets LTE working>?
I hope you guys can help me, I'm frustrated already, I bought an AT&T SAMSUNG-SGH-I317 and also purchased an unlock code, phone was working just fine with 4g on AT&T ( Tested ) but after unlocking I just don't get service when I use a T Mobile or Simple Mobile SIM.
On the About Phone -> Status I do get "Network: T-Mobile/Simple Mobile" ( Depending on the SIM I use ), but I don't even get EDGE, I cant make calls, I get the annoying emergency calls only, its making me crazy. Is there a way to fix this issue?
( I already added the APN settings, but im sure I don't need that to make calls, or get EDGE, I don't know what else to do to fix this ).
Thanks
maybe try factory reset? Possibly flash a different modem as well.

Factory reset would do nothing, the phone connects to AT&T with no problems, 4G and everything, but not even EDGE on T Mobile.
You already have a thread asking that question. .alot of people get mad when you clutter the forums.

Im confused... do you have a T-mobile Note 2? or a N7100? I beleieve the N7100 is the AWS International one, the Tmobile Note 2 is T889... or you could have an N7100 ROM flashed on a T889 (which existed in order to get 4.1.2 before the Tmo release).
Morning guys...
This is my very first thread on this forum so please bear with me if something was not done the right way.
Since I couldn't find an specific thread for this specific topic that's why I decided to post a new thread on this.
This thread will help you get a Stock AT&T Samsung SGH-i317 Galaxy Note II LTE phone with a stock ROM into Simple Mobile network with working 4G.
I can't guarantee this method would work on other Galaxy Note II models so please make sure your phone is exactly the same as the specs described on this link.
Also please be aware I cannot and will not be responsible for any damage this thread could cause to your phone. All I can say is, I tried this myself on my own phone and it worked for me and my only intention here is to share my experience to other users on my same situation.
So let's get into business!
Verify the phone specs. Please make sure your phone is an AT&T Samsung SGH-i317 Galaxy Note II LTE phone and that it matches the specs described here.
Get your phone unlocked. On a personal note this appears to be a must, so if you can't get it unlocked for some reason don't even bother moving forward down the list. I followed this thread to unlock my phone. Yes, the thread is for a Galaxy Note I, but it still worked for me.
Get it rooted. That can be done here.
Flash a stock T-Mobile ROM. That also can be done here which is the same thread as of step 3.
Enable AWS band. Is worth mentioning if you made it here successfully, then you already can use Simple Mobile just fine!, however you'll be stuck on 2G/EDGE unless you Enable AWS band here. This will let you enable 3G and 4G on your phone!.
Now at this point I'm sure you may be able to use another ROM of your desire, but I'm not 100% sure if that would work. On my personal recommendation I would first try the 5 steps EXACTLY as described above. Then if you still want to use another ROM, then you may need to repeat steps 4 and 5 with another ROM.
Now I also want to say, the credit is not all mine here. All I did was to compile the information altogether for you guys. Please don't forget to thank me, as well as the original thread owners compiled in this list.
Good luck in the Kitchen!
Reserved!
^^^Thanks, thread moved to general and stuck for easy reference.

Wait, You Menchtened LTE and 4G, And in which T-Mobile doesnt have. T-Mobile has 3G/3.5G HSPA+ but not 4G..
U dont need aws band on at&t phonez lmao noobs all u need is your phone unlocked and youll get on t-mobiles fake 4g .its cause t-mobile now shares at&t spectrum stop giveing people false info.

That is not entirely true sir. Not ALL areas have the 1900mhz Tmobile yet. You do need to unlock the AWS band for some areas to get the 4g. In my area (South Florida) they happen to have the 1900mhz 4g. I know because I sold an unlocked Infuse 4g (AT&T phone) to a buddy with a tmobile sim card and he got 4g on his phone.

Good information man. Ignore the OTHER GUY that is giving false information.
Everything worked for me, except one thing: CDMA VS GSM preference.
My CDMA signal is weak, so 4g cuts out. The phone just wants to default to EDGE as a first priority. How can I make CDMA the default preference so I always get 4g when available?

I have tried everything to get lte includes odin to stock wich should allow me to connect to tmobiles lte but wont. other people are connecting with no problem. can anyonw help me think of more ways to fix this. or is this particular phone not support 1700mhzaws. I really dont get it as the specs everyware state it does. also when I select all lte bands and selct t mobile it say unable to connect, try again later. I put my sim in a s4 t mobile and lte works so it cant be the sim. I also put at&t sim in my phone and lte works so my lte chip/radio is working fine. is maybe the free unlock methode not unlocking my phone completely? any way to relock and do it with an an unlock code. franky I am puzzled. I am in an area getting t mobile lte, confirmed on both my friends with a note 2 and s4 from t mobile.
My wife and I are considering taking our tmobile phones over to AT&T. There both unlocked... Note 2 & sg3. Question I have is would I have to flash AT&T modems and roms to be able to fully utilize the new network? Just don't want to end up with bricks. AT&T already told me both devices unlocked will work fine on the network.
Wat I'm asking is if I can utilize the lte on the t-889 if I put it on AT&T? I found a bunch of threads with mixed responses.

It should work fine but the only problem is you wont have LTE

Why's that? AT&T says I will be able to use lte since my area has it. If not I probably won't do this. As I've said I've read mixed responses. Could I flash AT&T radios to utilize it?
It will give you weak service because att and t mobile run on different bands which is hardware related not software

I dunno about that as many said everything works but LTE. I have also read a few that says they have LTE enabled. That's what's confusing. I may go to AT&T tomorrow and have them test a sim before I decide to switch. I assume if I change to AT&T apn ill get better 4g speed at least. The limitation your speaking to its a locked radio for the t-889 that prevents LTE from being enabled currently.
I can't quickly tell, but if it has LTE support on band 17 (700MHz) then it will work. It's a T-Mobile phone so it has support on band 4 which AT&T only uses for a very small part of its LTE network.
Like you said the radio it comes with might be locked to not allow LTE. If you can flash an AT&T radio without issue then you'd be able to see if it works.
If I were to guess I'd say it would have the right band since it's basically the same phone that AT&T sells.
Does it at least get hspa+ and 3G? I can wait for lte.

The AT&T rep you spoke to definitely isnt informed on the hardware issue.
If you are switching over you should just sell those two phones you have and just buy new ones since its new activation Im sure you can get a good price on the phones

From what I understand its not hardware, it's because of a radio limitation currently. Lte isn't enabled yet on the t-889. That's why I asked if I could flash a AT&T radio. As long as I get 4g and 3G ill switch. The whole point was to save $$ on buying new devices.

Well as long as I get 3G and decent hspa+ speeds ill be happy. I'll be getting the s4 anyways when it comes out. I don't have lte anyways with tmobile lol.
I understand that this phone has the same hardware and supports the ATT LTE bands. I am done with locked bootloaders, I need confirmation someone is using this phone on ATT Network w LTE successfully without any hacks..
Any other feedback will be great (call quality, radio performance on ATT network)
Seriously pondering getting the T-MO version. I am hoping I can get one off contract.
TIA
I am currently using the phone on at&t. LTE works. Just make sure you set your APN right. I just disabled WiFi calling because it is not supported.

Yes I am. I had to add the apn and then choose lte in the network section. Works great though.

Same here. Rooted, unlocked and running very smoothly, no lag at all.
Just need to get a case for it.

what is the apn setting bc im looking to switch to t mobile with the s3 att
I am NOT able to get this to work at all on mine. I am unlocked, rooted and I am using a red pocket sim that uses AT&T towers.
Any suggestions?
Did you get an unlock code from tmo, a 3rd party, or some sort of debug method a la s3 and note 2?

I'm considering buying the TMO variant to use on AT&T as well and I have a few questions related to this topic:
Would service reception be restricted to just LTE or can the T-Mobile S4 still receive AT&T's E, 3G, etc as well when used on AT&T's network?
Also, and I'm sure this is dependent on the answer to my first question, would the T-Mobile S4 work with the AT&T 3G Microcell?
Whos Lte is faster tmobiles or att.

hard to answer; it really depends on the area, but for the most part im pretty confident in saying t-mobiles LTE is faster.
see attached photo
I've been using the T-Mobile version on AT&T for a few days. I unlocked using the debug menu instructions in this forum, setup the AT&T LTE APN and set the preferred network to LTE. It works fine on LTE, hspa, etc.
Speed test results were 53Mb down, 19Mb up, 66ms ping in Raleigh, NC.
I gave away my microcell with my POS iPhone because the Samsung phones performed OK without it. So, I can't answer whether the T-Mobile version will work correctly with a microcell.

Help please...
Hi all,
I have a Galaxy S4 I9500, I keep my brightness at full all the time. When I finish playing games even "subway surfer" for 10 minutes, and exit to the desktop, I find that brightness is lowered alittle bit & increase gradually to the previous state which is full brightness (from 5 to 10 seconds). Could this be a result of that when playing games, the device uses the 1.6 quad core CPU and upon exit it takes alittle time (those 5 to 10 seconds) to shift to the 1.2 quad core CPU?
Really need your help.
Thanks alot.
So it seems this is the perfect phone to use on AT&T due to all that bootloader problems and crap on the AT&T version.
So folks still running fine without issues with this device on AT&T's network? I know LTE bands over lap so those are fine and the specs for the other frequencies all line up too but any problems with any data or voice stuff at this point after more time has passed? Including text and media messaging?

I had left an area with LTE coverage before I was able to network unlock, so I can't comment as to how LTE is working... but I've had no problems using it on Edge or 3G, texting/mms, etc. It even works flawlessly on my Microcell with no modifications other than the network unlock.

Mohan,
Which phone are you getting? The T-mobile version or the Google S4? I read online that the Google version of S4 is the same as the T-mobile version. I'm a T-mobile customer but I want to follow you using the Embryo rom on your new phone selection and hopefully get wifi-calling feature. I'm currently using the Embryo rom on my T989. Thanks.
adding an APN ... issues
lemme ask what will undoubtedly be a noob question. i've unlocked my T-Mo S4. confirmed. i popped in my AT&T iPhone 5's SIM card and boot up. i see that i have a signal, am able to make and receive phone calls. but no data. when i look at the APN, i'm seeing Cingular APN. what gives? i thought the phone would auto-detect and attach to the correct APN and i'd be good-to-go. thoughts? do i need to manually add the APN? I have all of the info necessary. when i try to add the APN, i am able to get to the proper menu, add all of the info. however, when i try to "save" the info, it never shows up as an APN for me to select. so whatever info i've just entered was never saved.
help!
