I know that it couldn't 5 months ago，but I don't know if it works today...
And if the international version doesn't work on Tmobile 3g and 4g, how about the Tmobile version of Galaxy S2（T989)？

Unfortunately it still doesn't work now and for the unforeseeable future it wont ever work.
Luckily the tmobile sgs2 does work on tmobiles network.
nope i got mine in europe and the antenna hardware acquires different frequency than the one in the US. Just google search "T-mobile frequency"
I thought there was a version from asia that had a aws band. And are any of you using the europe one on T-Mobile? If so how are slow is 2g?

ok！I give up buying the international version since I live in The US......
So，how about ATT version（i777）？does it work on Tmobile 3g and 4g？
It's just because ATT version is cheaper,and so is Tmobile's plan.

No..............
I'm Galaxy Nexus owner. I have T-mobile and it works with HSPA+ without any problem. It is really fast.
In a blog I read that International version of SGSIII doesn't not support T-Mobile HSPA+ & 3G.
I wanted to be sure before ordering the phone.
Do you have any information about this?

So, the trade-off for early access to the much-anticipated phone is less functionality. The international model’s 3G HSPA+ should have no problems with the AT&T network – though won’t step up to LTE – but won’t work on T-Mobile USA’s 3G as it lacks support for the 1700 band.

Are you sure that's what you read?
Another way of reading it, is that T-mobile doesn't support the 1700 band, required for LTE. But what do I know? I only know that the modem firmware certainly supports the 1700 band, but whether or not this is implemented in hardware is a different story, but it would have been stupid not to have done it. The only way to tell, is if someone can start posting some internal pictures of the PCB so we can see what radio chip sets are used within.
You will not get HSPA or even 3G speeds with the International S3 on T-Mobile. HSPA is T-Mo's 3G network and it requires 1700/2100 band, which the S3 does not have.
At best, you will get 2G (or EDGE) speeds, and those are not very fast at all. Streaming anything would be pretty painful.

HSPA doesn't require 1700/2100 in all cases, but it does in T-Mobile's.

Yep, that's what I said. Specifically, it's the 1700 (download) band that TMo's HSPA network is using that the S3's radio doesn't have.

Got the message...
However, what about AT&T? Will I get 3G (HSPA+) on their network? As you probably know, there are SIM cards for both T-Mo and AT&T available to work with the international version of the S3.
What band does AT&T use for 3G/HSPA+ , and can the unlocked S3 use it?

Yes, it will work fine. ATT HSPA+ is using 850/1900 and is completely compatible. You will get HSPA+ speeds with the Int. S3.

Galaxy Nexus is penta-band (it supports a bunch, including 1700), and hopefully the next nexii will be as well.
To check for compatibility in future, you just need to compare the phone's frequencies with those listed for the provider (can probably find them on wikipedia even). In this particular case, you'll have to wait for the t-mobile s3 if you want hspa+.
It is worth pointing out (and I'm surprised that no one has done so yet) that T-Mobile USA is working to have hspa+ working with the 1900 band by the fourth quarter. So if the international S3 doesn't initially get hspa+ on tmo, it will by the end of the year, possibly even by the end of summer.

I know they are doing this, but I doubt it will be done anytime soon especially since they want LTE out next year. So far this has only happened in small sections of Colorado and California. I hope they will finish soon but it just doesn't seem likely.

Agreed, you shouldn't make phone decisions on the basis of something that might happen eventually; who knows when they'll even get to your geographical location.
The baseband chip set is the same in Galaxy Nexus and i9300, so I see no other reason for not providing T-mobile compatibility apart from either not having had time to build the baseband firmware to conform to T-mobile networks or simply that T-mobile is doing something "wrong"! (Yeah, they tend to complicate things by reinventing the wheel, and Samsung are probably getting tired of having to provide them with separate models and modifications all the damn time, just because of it.)

You're wrong.the reason they're doing this is because of Lte. They want to use the 1700 band for lte and the 1900 for hspa since they don't have many people using the 1900 bands for gsm. So it'll happen really soon.

I guess that depends on your definition of "really soon," but last I heard, TMo wasn't beginning the LTE transition until "early 2013".

But first they need to clear out the hspa 1700 spectrum for lte, and that's planned for later this year.

Clearing out 1700 for LTE doesn't mean 1900 will be refarmed at the same time. They have been "refarming" for quite a while and still only have small areas to show for it.

It has nothing to do with T-Mobile. If pentaband phones can exist it isn't that big of a deal to include the band. It is a European phone and they don't use the 1700mhz/2100mhz combo band that T-Mobile uses.
T-Mobile also isn't the only carrier in North America to do this, so it's not like they're the only one.
galaxy s3 has HSDPA 850 / 900 / 1900 / 2100 , no 1700. so it doesn't work with t-mobile 3g right now.
how to get 3G with AT&T? i got only 2G
1.) Make sure your phone is 3g capable
2.) Make sure you live in a 3g area, which most of the country is.

No, it wont work with Tmobiles HSPA, I think Tmo is changing their HSPA to 1900 next year so that would of been a different story, but for the moment its just not worth it.

While I should say use the search bar, all the information I've found is pretty outdated regarding this.
The simple answer is that you probably can't get it to work, at least not 3G/4G, if Edge is fine then you can unlock the phone with "Galaxy S Unlock" in the play store, just follow the directions listed, it's pretty simple.
The extended answer:
You might be able to depending on where you are. T-Mobile generally uses the 1700 MHz and 2100 MHz bands for 3G/4G, but the i777 doesn't use the 1700 MHz bands, instead it can use either 850, 1900, 2100 MHz bands for 3G/4G. However in preparation for LTE and just to increase bandwidth across 3G/4G they are starting to take some of their 1900 MHz spectrum from their edge networks and move it to 3G/4G/LTE. This has just started happening very recently and is currently in very few markets, however you may be in one of those, it is still expanding if you aren't but it may take a while. The only way you could know is if you took a T-Mobile sim card and put it in an unlocked i777 and if you get 3G/4G then you are good, otherwise you are stuck with Edge.

The S2 for ATT doesn't support 3g for T mobile and vice versa. There could be some weird instance as mentioned above where it could work but in most cases it won't.

Mostly true, T-Mobile's S2 should work with AT&T's network, you may have to flash a new radio but theoretically it should work.
You cannot port a T-Mobile ROM because T-Mobile does not have a similar gs2. The T-Mobile gs2 is the twin brother to the skyrocket

Sorry for the late response, I haven't been on here much lately.I live out in Little Elm, slightly past Frisco close to Lewisville Lake and 380/University. I am about to upgrade my phone again and give my wife the GS3. haven't decided between the GS4 and Note 2 yet.
I am in So.Cal and got 4G out of Edge half of the time from Tmobile ofcourse. The speed is around 7-10Mb/s or so
is there a rom ported from att to T-mobile
