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
I just sold my skyrocket and got a real good deal on an unlocked tmobile s3. I changed my apn and it is showing 3g but my speeds ar 150kbps at best. I did alot of research (i am not saying there is something out there i could have missed) but all i could find is people saying they are getting 4-5 mbps, but nothing about what they did to get them. Some people are saying they are flashing att radios and roms but then other people are saying not to do that. How do i get hspa speed, should i or can i flash att radios and roms?
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?

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.

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).

Using a Sprint GS3 on Page Plus may mean that the 3G won't work. As Page Plus operates on Verizon's network, the Sprint radios in your GS3 won't operate on Verizon's 3G frequencies. Your best bet would have been to buy a Verizon GS3 as you likely could have gotten the 3G to work.

How does, then, one sell a Sprint GS3 (SPH-L710) with 3G working on PP, on eBay? There are listings if you will see, with a working 3G. I just made the mistake of buying one with 1X data.
1X just means that you're in an area with no 3G. It doesn't mean that you're getting "1X" data speeds because 1X is what SMS and MMS are transferred over, its not actually a "data" signal
It may be that you just dont live in an area where verizon gives 3G

I'm pretty sure Verizon has 3G here (I live in the city of Chicago, and moving around the city doesb't give me 3G either).
Anyway, I'm pretty sure the guy who did the flashing couldn't get 3G antenna to work with PP, which is what he told me.

This seems to be a recent development for myself, then. There are a few Sprint phones that look to be fully flashable to PP with 3G/MMS working. You may have purchased one that wasn't fully flashed. Making it work would likely require changing more than just the APN. My advice would be to contact a seller on ebay who is offering the service only and see if they can assist.
Why not just flash the radios? Your on xda where everyone flashes about everything. The seller would of flashed them. But not to mention he's legally not allowed to do anything about phones that are flashed to a different network as it became illegal the other day. Someone please correct me if I'm mistaken

No idea how to flash the 3G radio.
As far as the legality is concerned. This phone was unlocked much before any of that, and since now it is not tied to any carrier anymore (and no terms of service), making changes to the firmware should be perfectly legal.
You'll need a donor phone to get 3g. Some might help you here, or go over to the Page Plus forum @ Howardforums and you should find your answers there. You'll need a newer build of QPST and DFS CDMA Tool demo.
Just made the switch over to att and I am getting really slow lte speeds. Can anybody help?

Tried every APN setting possible already. Searched all the threads and still no help.
There's a thread on here about flashing the AT&T modem and it solving the problem. Plz search and find it...
Here I found it for you..

Thanks for the advice but I read through the thread already and it doesn't seem like it will improve drastically. So I rather not attempt to flash a modem that may cause a soft brick. My brother has a N900a and gets almost triple the speed of my lte. What gives?
I dont always get fast speeds. I'm guessing at&t phones get higher priority than other phones. There is a build.prop that you can flash/edit that may or may not work. I, myself, haven't made any mods because I get higher speeds usually. Not always. I am on a 900T but using an international 9005 rom with T-Mobile modem still. It really boils down to is the risk flashing a modem or build.prop worth it. In downtown houston I rarely dip below 10mb/s on LTE and occasionally see over 20mb/s. The congestion is real bad here so it is very often I get bumped back down to hspa. Like I said, you have to weigh the risks. I am fine with how it is working now. My post probably hasn't helped you get you where you want to go but it may help you to be content with what you have or may consider flashing an international rom minus modem and see if that helps.

I'm on straight talk att sim and it's ridiculous on an att phone I get att quality signal. But with this tmobile phone when home I can only get signal in my bed room by the window . From I walk into building calls and signal dropped dead . It truly sucks. I'm switching back to tmobile as soon as this month is over . I hate paying that extra 30 dollars but a phone is no good in one room .

I as well am on Straight Talk At&t micro sim and I get pretty decent speeds I believe Straight Talk cap's their LTE speeds at 15 down and I think around 8-9 up which ain't bad for the Chicago area. But there are times where I barely get 2 down and 4 up. I also have a Tmobile Note 3 stock/rooted using a ST sim.

The speeds are fine when I actually get a signal . Its the fact that I have dead spots in almost my whole apartment except the rooms located to front of building . It was never like this before .

Tmobile Note 3 on ATT Network
I have a Tmobile unlocked phone on ATT and I can't find out anyway to speed up the LTE. I get LTE it seems, but it cuts the speed in half compared to my girlfriend ATT variant Note 3. I tried to flash an AT&T modem to it, but then it would soft brick the device and wouldn't boot. I have tried every APN I can think of, but still no success. I have tried the build.prop, like adding the lines for faster data tweak, but still nothing is getting better. I have full bars, but speed is slow. Do you have any suggestions on what to do, b/c I am out of options. Thanks.
Add me to the list. Just switched over to AT&T from T-mobile, but get very bad speeds. The only reason why I switched over was because with T-mobile, I was getting poor quality signal almost EVERYWHERE, so I had no choice.
I'm curious; if the bands in our phones support the proper AT&T bands and we actually get LTE, it's gotta be a software issue. Modem most likely.
Yeah im sure it has to do with the way the modem is optimized for ATT's 1700 band. I'm also in the same boat and have flashed ATT's modem but it doesn't work. Others have flashed ATT modems but I dont think anyone has been able to successfully see their baseband change in the settings so no one can say whether it worked for sure. I can tell you that the bars have nothing to do with your call signal though, its just your LTE signal strength. If you really want higher signal in your house if LTE seems to drop or be super slow, you should manually switch over to use HSPA+ in your house. Its a pain...i know.
I'm hoping eventually the newer modems fix the 1700 mhz frequency optimization or some devs figure out how to successfully flash N900A modems on the N900T.
LTE speeds
I have great signal almost always it seems like. I have full bars on LTE or 4G/HSPA+, but if I put my sim card in my AT&T variant note I get at least twice as much throughput than with the note 3 tmobile. It has to be a software issue, I have tried to flash att modems with no success. Just got to wait for a tweaked modem. I have even tried tweaking build.prop file and it works a little bit but not much. It is just weird I have full bars with LTE, but I won't be able to get data sometimes, which is really weird. I think there has to be something with the signal bars showing higher dbm that it actually is receiving. Probably another software glitch. Well if anyone has any insight on this issue let us know, please been looking everywhere.
LTE speeds
I think also that the modem is not the only issue. I flashed a kernel today after being on the stock kernel on the T-Mobile and I did a speedtest and the speeds were really low. Flashed another kernel and boom faster speeds back to where I was, maybe higher, but I will monitor to see what happens. But I read that Kernels do affect data speeds sometimes. I am just going to keep looking around to see if any kernels work.

AFAIK it has nothing to do with kernel I might be wrong its just the modem

Is there any tweaks that can be done to kinda help the LTE or at least fix my signal bars showing full all the time. I am thinking it is not switching towers when it is supposed to and giving a false signal strength. Is there anything on modifying like you can on Sprint phones with dbm on wimax, where it will switch antennas.
Has anybody flashed the new N900T NE6 based ROMs / modem and seen any difference?

I upgraded the modem and bootloader to the new NE6 version. I'm on Temasek CM11. My observations:
Signal strength is slightly better. Speeds are definitely much better. Prior to the upgrade, I'd get around 6-15/down, 3/up. Now I consistently get 25/down, 10/up.

How did you get the new modem to stick? Did you do the triangle away method? If so, did you have to revert to a stock kernel first? I'm trying to upgrade only the modem and leave the bootloader as is. Is that a bad idea?

It's getting incredibly frustrating to have to repeat this a number of times. I think this morning I had to repeat it already 3 times. Please do a search; there are plenty of pointers on how to get it done. For reference, here is what I did.
