I have the opportunity to purchase a new AT&T Samsung Galaxy S3 for a good price. But I have service with T-Mobile. If I get the phone unlocked, will I be able to purchase a T-Mobile Micro Sim and have the phone work correctly?
It is the SGH-i747
That's why its called "unlocked", so you can use it with whatever carrier u want....yes it will work fine.

Keep in mind you'll only have EDGE speeds. It'll function, but it won't exactly be enjoyable.
Yep work just fine but slower data.
Now as for unlocked I too used to think that meant it would work for any carrier but that is not true! U can only use on carriers that use the same frequency bands that the phone supports ie. 850/900/1800/2100, etc. Some carriers will use different bands that some phones don't have but if ur dealing with the major carrier ur OK it usually the smaller guys that use poorer or less common freq's that some phones don't use

Hi all, i travelling to hawaii soon, and was thinking about purchasing a galaxy s3 while i am there, will i have any problems using this phone once i return to australia, i also noticed there are many variants of the s3, is there any i should avoid, or are they all the same but with different bundled software ?
i am keen to flash this device with custom roms in the future, so bundled software is not a huge concern of mine
Its either at&t or T-Mobile versions of galaxy s3 will work in your country but remember it will be sim locked...
Edit: might vary in Hawaii not sure if T-Mobile has network there...

They definitely have network there. My brother just moved there, and there are a few members on here also.

Yes there's network here. Lol.

Wouldn't i be able to use the application 'GalaxSim Unlock' to unlock the sim, or would the S3's in hawaii likely be the Us qualcomm based GS3's ?
Why dont you just get one in Australia? Seems like a lot of trouble to go through? When you in Hawaii you just have to put a prepaid sim in it for it to work. Then when you go back home you have a phone that works well for your country without the hassle of doing something special to the phone to make it work for you. Plus you wouldn't be able to access the 4G networks of the Australian carriers with US variants.

Because they are much cheaper to buy, also, i do not consider unlocking/flashing etc to be a difficult task, i actually enjoy it, call it a pastime that i enjoy if you wish.
Also, only the 4G version of the S3 is going to work on a 4G network, so if i dont buy the 4G version, its not going to be a problem anywhere in the world
Fair enough.

What? All versions of the S3 are "4G". The one in hawaii will be Qualcomm based. If you buy an ATT one in Hawaii the LTE will not work in Australia

i beg to differ in regards to your comment of 'All versions of the S3 are "4G"'
So I've been hearing that there have been people using unlocked smartphones with the cheap data plan for non-smartphones on AT&T. But I heard that people have been using unlocked phones and international unlocked phones. So what's the difference? If I had just an unlocked Samsung Galaxy S3, would it work with the $10 unlimited data plan for non-smartphones? Has anybody tried this and it worked?
The reason the international smartphones are able to use the non-smartphone plans is that at&t doesn't recognize the phone. AT&T would certainly recognize a phone that was made to work on at&t and that they sell in their stores on their network whether it was unlocked or not.

So if it was an unlocked phone that wasn't originally from At&t it should be ok? What about the SIM card? I heard something about a microSIM card before. Do I have to get one of those?
Actually ATT has been pretty good lately at sniffing out those who try and use dumbphone data on smart phones. You can try but no gaurantee it will work. The Intl GS3 does have better dev and arguably better components but ATT GS3 has LTE.

Yea, but the i9305 is LTE 800 / 1800 / 2600. That's not going to cut it on AT&T.
So, this is more complicated thant i tought. I was under the impression that I could prety much unlock my phone to work with any companie.
Called Telus ( I want to sell my T-989, and found a Rogers buyer)
They told me they could unlock it but that it wouldnt work since Telus is on a HSPA network and Rogers is on a GSM...
Any way to get around this by flashing a different modem ??
Or am I stuck to sell it to a compatible network buyer?
I have this phone unlocked and it works fine on Rogers. It just can't do the hspa+ speeds so it would be stuck on 3G.
So basically don't worry, the phone works fine on gsm carrier's.
Also for future reference Telus is using a CDMA network but the T989 supports both CDMA and GSM.
Sent from my SAMSUNG-SGH-T989 using xda app-developers app
That is great news. Only thing is that Telus want to charge me 35$ for the process.
Are the online websites that offer that kind of service trustable ??
Iv'e seen a website think its like cellphonecanada blabla something like that. 20$ for the unlock.
I got mine unlocked at a local mall for 20 bucks. Perhaps try that?

Ok ima try to keep it as short and simple as i can. I have a stock T-999 s3 tweaked to perfection running of Net-10 prepaid with the bring your own sim. Not only that I have it network unlocked so no matter what sim i place in weather its AT&T, t-Mobile, straight talk ect. i have service, each service i can critique to its best functions. Now heres my point. I also have a US Cellular galaxy S3 , rooted, and no matter what i do or try i cannot get this specific model to run a gsm provider via sim card. Im no wiz, but i get the idea, and my idea is to take this phone that is not supposed to operate on gsm carriers and make it operate. A recent example of success doing so was with my Droid Razr Maxx HD, i was able to successfully root the phone but as you all know verizon does not support us gsm carriers within the united states , or even on their network for that matter they block it. however after flashing a different modem, i am currently running t-mobile with great service! So any talk of "its impossible" i dont need, negitivity is not needed. i am fresh to this stuff but it fascinates me. cutting to the chase, what needs to be done to this sgs3 model #SCH-R530U to make it operate and function on a gsm carrier within the United states. Hacking Manipulating and tricking is all welcome that what were all about. Ive tried several things changing to global mode, gsm only,, faking gps positions to outside the u.s. and apn settings among countless hours beyond and im at a loss.. please im open to ideas and suggestions hopefully one day we make every model capable as nevery other
I believe the issue you are facing is because that particular S3 does not contain the necessary GSM radio chip needed to use those networks.
According to this (and its a wiki so it could be wrong):
http://en.m.wikipedia.org/wiki/Samsung_Galaxy_S_III
That S3 does not have any GSM bands for 2G or 3G.
However, once T-Mobile launches its 4G LTE on the AWS band, it should work...assuming the 4G network is both voice & data over LTE AWS.
The RAZR does work cause it does have the necessary 2G/3G GSM radio chip.

Simply put, the Verizon galaxy s3 is the only variant that has both CDMA and GSM bands. So if you wanted to do what you're saying, it would be most possible with the Verizon variant.
But for what you want to do, you'll need a world phone. And I believe the Verizon s3 is a world phone. Just gotta "hack" the GSM bands. Since they aren't active by default. But your T-Mobile att s3 will never work on CDMA. Also not lte will most likely not work on other carriers.

Just curious about this. There is a lot of talk about T-Mobile S3 running/not running LTE once it starts, but what about this setting on my T999?

"So I put my phone into airplane mode and threw it... worst transformer ever. -.-" -My friend
Have an AT&T i317 unlocked with a T-mobile data sim.
I've done the tweak to enable the 3G/4G bands, a la http://forum.xda-developers.com/showthread.php?t=2068041
But now T-mobile added LTE in a few markets. I drove through one and suddenly got no data access. This is with "preferred network mode" set to LTE/WCDMA. If I switch to GSM/WCDMA, all is well (it sticks to the HSUPA and H+). So clearly it thinks it's on LTE but the phone can't access the T-mobile LTE.
I'm using Cyanogenmod 10.1, android 4.2.2, which also makes the model number show GT-N7105 instead of i317.
any tweaks to add the LTE? do i need to dump CM and use a diff ROM? do i need to go back to stock first to do any of this? (Right now, I can no longer dial *#7284#)
Thanks!
I am having a similar issue, I have a sgh-i317 with aws mod and the phone is not picking up t mobile lte even when placed next to a sgh-t889 that is getting it. Lte works with att sim but not working with tmobile sim. Any help would be great. I have tried many roms and modems and reflashing aws mod. Roms inculde jedimaster13/14 jedi x13/14 both att and tmobile versions and clean rom and stock 411 and stock 412
I figured it out see

Does the AT&T version have LTE? If it doesn't have the capability, but he modem is telling it to access it when it sees it, that might be why it dropped out completely. I'm mostly curious to see if AT&T LTE devices can use t-mobile's LTE network because I want to get an s4 active and I don't want to lose LTE by making that switch.
Try this for me, instead of that model number you have. Change it to the T-Mobile model#. Which is going to have to b done thru the build prop. Then reboot. Then go try and c if you pick up lte.
Because I just flashed a AT&T Rom on a T-Mobile GN2. And I pick up lte just fine with my AT&T SIM in there! And no AWS MOD what so ever. But the MODEM is still TMO, it'll always b TMO. Flash a att modem on a TMO GN2. Brick city.
Let me know what happens just curious!!
Edit: the Rom I flashed was SKY NOTE 9. No modem included!!!

I don't have any solution for the question but I do have a question of my own.
Why do I keep reading of people buying att devices for t mobile, why not just buy the t mobile version?

WELL, here's your answer.
Maybe they getting the device at a cheaper price. Which would make someone but it. Instead of spending a lot more to have have the carrier brand you need. FYI
Both the phones are exactly the same. Besides the model# and done bloat. Like I said above, if it's unlocked it'll work, with both carrier's. So why not have that option to switch... and one more thing being able to take the phone internationally, and pop a SIM inside and ya have service. No roaming !!!
Just my 2¢® 2 you're question...
Att now has prepaid lte plan almost same as tmobile only .5 gb less of data everything else the same at 60 dollars . Plus att has better coverage well at least in the areas I frequent .

When a t-mobile version is available, I do buy it, but with ATT exclusives, that's not an option. For instance, I want the s4 active for its water resistance. T-mobile will soon offer the xperia Z, but when you compare the features and perormance, the s4 active is better, so for the money i'm willing to spend on a smartphone, i'd rather have the s4 active.. the hardware is capable of t-mobile LTE, but it still has to be configured properly with firmware and software to use the radios correctly. Since radios are some of the hardest pieces of firmware to alter, it's worth doing this investigation / collaborating to find work-arounds.
I didn't get tmobile lte on my at&t note 2 until I flashed the new at&t radio. That's all that had to be done. I'm using Skynote9 too. I did the aws mod again so I could get h+ 4g speed enabled and now is a flawless tmobile phone. Let me know if it works for you.
