I can't find an answer on this subject, so forgive me if it has been answered.
I have the older version of the Galaxy s3 from t-mobile that doesn't get LTE . I know that LTEis available in my area, if I root my phone, can I get access to LTE instead of just 4G, or am I stuck with 4g/3g forever?
Thank you!
Nope, the original T999 is not capable of LTE. That's why they had to release a new model. It was either that or stop offering the S3 at all, which wouldn't make for a very good business decision. But if you happen to be in a market where they upgraded to hspa+42, you will be able to get very close to, sometimes better than LTE speeds. If not then it's just hspa+21, which most would agree is still very good for mobile data!

No, your phone doesn't have the hardware to support LTE. Therefore, you're limited to HSPA+ unless you get the T999L.
I'm not sure why LTE is so highly valued. I download 1-1.8 MB/s on HSPA. Yes, megabytes.

Yeah I am trying to figure out if I get an ATT gsm version would I get 4g speeds or would I be stuck with edge? I'm debating if I should do A trade or just go buy a nexus from google play.
You will probably get 3-5 mb/s in non congested area or non peak time. Some areas peak higher. But I wouldn't expect higher than 3 mb/s anytime. And in my area that is stretching it from 8a to 3p.

I currently have an unlocked GSM version on ATT and I have seen some downloads as high as 8-9mbps down. I average around 3-5.

An ATT specific version does not exist. The GSM Nexus sold in the google play store supports HSPA+ with both ATT and T-Mobile networks.

Oh ok, the guy in the thread said it was an AT&T variant thats why I asked, usually ATT phones only get edge or whatever.
Yeah most phones are that way. The galaxy nexus had a penta-band radio so it supports both.

Huh? not sure what you mean by that... If you have an "AT&T" branded phone and put it on T-Mobile it'll get EDGE only. And vice-versa. There are plenty of unlocked phones that will get HSPA+ on AT&T though, they just have to support the right frequencies (most do).
The GNex supports EDGE/UMTS/HSPA+ on AT&T. You'll get full speeds that any other HSPA+ device will get on their network. You will not get LTE.
You'll also get full HSPA+ support on T-mobile.
it all depends where you live..
Yes you will get 4G ATT speeds on your galaxy nexus... But you wont get LTE Speeds since it don't have a LTE Radio
i can get 5-8Mbps down on a good day..
but i avg about 2.5-4mbps
I'm debating between the T-Mobile and AT&T versions of the SG3. I'm currently planning on using a prepaid T-Mobile service but I can see myself in the future possibly switching to a postpaid AT&T plan.
If I buy the AT&T version I will be stuck on EDGE when on the T-Mobile network. No one has gotten T-Mobile's HSPA+ or DC-HSPA+ to work on the AT&T version of the GS3.
If I buy the T-Mobile version I won't have the option of using AT&T 4G LTE if I choose to go AT&T in the future.
So: does the T-Mobile GS3 physically have the AT&T 4G LTE hardware, and could it be activated?

I looked into the exact same thing before taking the plunge. Apparently, even though they have the same hardware, there is a trade off no matter which one you choose, so short answer is no. (But who knows,there are smarter people out there who may prove me wrong...)
I can tell you why I went with the T Mobile version if it will help with your decision...
1. TMo ver will work with HSPA on both TMO and ATT (As you pointed out, the ATT will only get EDGE on TMo)
2. I previously owned 2 LTE phones and battery life was horrible. Giving LTE up was not that difficult for me since the trade off was batt life
3. HSPA speeds are enough for my uses (You will rarely ever get advertised speeds with either HSPA or LTE)

Got it. Thanks. Even if I go with AT&T I might not even want to use their 4G network since it hogs battery so much? I've currently got T-Mobile and the fastest I've ever been able to clock is a measly 5mbps. A far cry from even the "slow" 21mbps speed that HSPA+ advertises.

Also, ATT may or may not have LTE lit up in your area yet. You may be waiting for a while. I had an HTC Thunderbold and a Galaxy Nexus on VZW for a few years and it was only towards the last 3 months of my VZW service that I began to get LTE lol HSPA is much more widespread as of right now on ATT

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/
~Aqua
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

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
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 am getting the 4g bands but my phone will not connect to the lte bands of t mobile. is anyone else having this problem? 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.
Hey All,
I've placed a Tmobile sim in my Att unlocked GS3. Ive seen many posts stating that the Att version wont get 4g on tmobile but 4g works fine for me; regularly I can get 5 to 10mb downloads. My issue though is that Im sometimes dropping from 4g to 2g/Edge then back to 4g. Should my phone be dropping to 3g instead ? Im quite shocked when it happens since I usually had strong 4g not far away at all.
Is the general consensus to to simply get a Tmobile device instead of bringing something from at&t? I really dont want to root the phone or flash roms at this point since Im just testing out the service.

You are in a refarmed market from the sound of it. The reason you go from 4g to EDGE is because the refarmed spectrum is most likely not through your entire coverage area.
T-Mobile uses the 1700 band, which at&t does not support, as their primary 4G deployment. This is why it is always recommended to get a T-Mobile S3.
That said, there is a firmware image for at&t's GS3 that unlocks T-Mobiles AWS band not just for 4G but for LTE as well. It is in the at&t forum - you will have to read the entire thread to get the relevant files and information on how to do it. Note that this CAN brick your phone permanently so only attempt it if you are willing to take that chance and you are familiar with download mode and ODIN.
The upside of using that hack is that the T-Mobile S3 doesn't support LTE at all.

Thanks for the clarification and info about the hack. Assuming I get a Tmobile device, should I expect to see a 3g icon instead or would it still say 4g?
