No. Only edge network will work. 3g and 4g work on completely different spectrum and radio frequency

If that was true the galaxy note from att wouldn't get T-Mobile 4 g which it does when flashing a blaze 4g modem I also want to know if this will work on the att s3

That may be true about the Note 2, but an ATT S3 does not have the T-Mobile 3/4G frequencies.

Yes this guys right. Take a look for yourself:
ATT Galaxy Note Specs
T-Mobile Galaxy S3 Specs
ATT Galaxy S3 Specs
Notice how the Note and the T-Mobile Galaxy S3 have that 1700 Mhz frequency? Thats what T-Mobile broadcasts their 3G/4G spectrum on. If the phone doesnt have those frequencies, then it wont work no matter what you do.

That's different. It is a whole different phone with a whole different SoC.
Let's not say things that we cannot prove.

Don't shoot this guy completely down. It will get T-Mobile 3g/4g as soon as T-Mobile refarms their network.

Yeah, because they live in one of the small parts of the US that uses the 1900mhz band for HSPA. It will not work everywhere else.

What about the other way? A T-Mo SGS3 on AT&T? What does that get you? I know NO LTE but what about HSPA+ ?

Yes, HSPA+ will be fine. But as you said, no LTE.

[Q] Can you use this on AT&T network and vice versa when unlocked?

Hi,
I basically want to know if there is any difference between these devices, other than network provider lock.
Can you use the ROMs interchangeably?
I think the tmo model does support att's bands and u can probably interchange roms as well like on the tmo s2 and the skyrocket

We don't know for sure yet that the ROMs will be interchangeable. However, given that most T-Mobile phones support the 850/1900 NAM bands (GSM) needed for AT&T HSPA+, as long as the phone is unlocked it should work fine.

The Galaxy S2 did. Reading the specs page on the Tmobile website, I've come to the conclusion that the bands are identical to the AT&T variant's. I'm going to be doing the same thing.
Will hspa+ work? If so, tmo users who will be paying full price would be better off
Buying from att because its less than tmos full price cost.
Plus wireless tethering would work Because tmo doesn't have imei # of att phone.
Can anyone confim?
i would like to know this as well, paying 549 if a lot better than 639.

FYI only T-MO has HSPA +42 version of the S3 for those looking to buy from At&t.
anyone can confirm this?? does the gs3 from tmo works on att HSPA+ and vice versa and if the tmo gs3 works internationally on 3g networks.
All right,unlocked my T999 galaxy s3, put my AT&T micro sim in phone but I get no data. I can make phone calls no problem.Do I have to do anything with the APN settings?
Thank you!!
You need to make an AT&T APN. Also the AT&T version will not get 3G on T-Mobile without at the very least a modem flash.

O.K. just added a couple ATT apn settings still no data.any other suggestions?
By the way i have a 4g micro sim.Thought Tmobile S3 had ATT hspa+ bands.
Got apn settings from these forums.
Might want to do a lot of research before trying to flash an att ROM on tmo or vice versa. I heard the tmo phones are quad core.

did you flash an AT&T radio? you will probably need to do that.
how did you unlock your phone? did you just buy a code or did you try one of the XDA methods?

I'm hoping you fellas will help me out here.

I'm buying an unlocked T-mobile Galaxy s3 from a really nice guy. I'm on AT&T, and would like to A) confirm it will work on HSPA+, and B) I would like to know how to go about setting it up on the Medianet plan.

Someone may correct me but I don't think HSPA+ will work on ATT. They use different frequencies. If you had the international SGS3, HSPA+ would work on ATT.
OK thank you, I'll pass on the GS3, I'll just keep my iphone
It works. T-Mobile s3 has the frequencies needed. My s3 is T-Mobile unlocked and using it with at&t.

+1. The T999 supports 850/1700/1900/2100 for HSPA+. Therefore it will work on Atts H+. I use both T-Mobile and straight talk on my t999.

I assume that is something to do with at&t if so, you would have a better chance asking there.

[Q] Does T-Mobile note2 work with at&t lte or hspa?

Guys,
I so want to buy the note 2 like today. However T-Mobile has no coverage in my area. If I buy the phone at full price I can get it unlocked. Am just wondering if T-Mobile note will work on at&t lte Or hspa+.

The phone does support HSPA+ on AT&T out the box since the bands are included. The phone also has T-Mobile LTE frequency as well, but is said to be locked down by software since T-Mobile does not have LTE up and running yet. I believe T-Mobile and AT&T do use the same frequency for LTE. Only way to know if someone unlocks their device and puts in an AT&T sim.
According to AnandTech review it WILL support ATT LTE. So how does a non-Tmobile user unlock this phone??? I want to use on ATT.
From the review...
http://www.anandtech.com/show/6386/samsung-galaxy-note-2-review-t-mobile-/9
One of the most interesting things about the Galaxy Note 2 on T-Mobile is that it literally is the same hardware as the AT&T Note 2 with LTE. Sure, the model number is different, but the T-Mobile Note 2 includes support for LTE bands 17 (which AT&T uses) and 4 (AWS, which AT&T has specced devices out for and T-Mobile has confirmed it will deploy LTE on). This is to my knowledge the first T-Mobile handset with overt LTE support, and thus a solid future-proof purchase if you’re determined to have a T-Mobile handset that will work with the carrier’s upcoming LTE on AWS plans.
In addition, if you unlock the handset there’s no reason it shouldn’t work on AT&T’s LTE network that I can see. I managed to unlock the T-Mobile Galaxy Note 2 but not before leaving the AT&T LTE market in Dallas. It does however work as expected on WCDMA 1900 in my own market on AT&T after unlocking.
Will the Note 2 work on streight talk as well?
I'm curious if the note II would work on att's 3g network. I'm with Sprint atm but I'm constantly roaming due to poor coverage so I'm assuming it won't be long till they nix my contract and paying $100+ for limited data is just ridiculous to me so I was going to go with TMobile but they only have.edge coverage around here no 3g so I was hoping if I went with TMobile I could use AT&T towers and actually have a decently priced plan with real service.

Im in the same boat im going thru the same thing I have both simplemobile/tmo and Att for work and i played with the international version and ofourse it was fine with my Att sim i didnt try my simplemoble/tmo sim at the time but im hearing the tmo version is exactly like the att and international one so imma just use my work phone/att to save some money(I use google voice so it doesnt matter what phone i use same number) and plus im suppose to get a discounted price so lets say i can possible be very happy this weekend!! but imma take the chance all the info i read states it will work with Att hspa+network so well see soon! if nobody tries it before me...
I took the plunge...
I bought the TMOB version
Cellunlocker.net unlocked it (I selected the international note 2 option)

LTE band might just be software locked since T-Mo has yet to get LTE, FCC filings showed LTE capability. YMMV

Make sure your using the right APN....... if your not using the right APN you won't get lte

Most likely your going to need the At&t radio just how At&t note 1 worked on t-mobile 4g by flashing the radio... maybe even a full on rom from at&t version since all the phones now come with the same hardware

T-Mobile Note 2 on At&t LTE??

Hey guys! I just got my Galaxy Note 2 today and i am already ready to mess with it.
I was looking around and saw some threads saying that T-Mobile and At&t versions of the Galaxy Note 2 have the same LTE band and frequencies. And that you could run a T-Mobile GN2 on At&t LTE...since T-mobile doesnt have it just yet.
I am currently on T-Mobile with a t-mobile SIM. I am curious to if I flash an ATT modem/radio to my T-Mobile GN2 would that give me the ATT lte capabilities?
I don't want to jump the gun and brick my phone the first day i got it lol.
No that doesnt work...no one has gotten it to work yet. But one member is getting an update from tmo for their lte and is gonna upload a backup so the devs can hopefully turn on lte on the phones so when tmo turns on there towers we will get lte

I have both! What I can tell you is that both are unlocked. And that I can get LTE on the TMO GN2, with my AT&T SIM in there. And on the TMO I also flashed a AT&T custom Rom SKY NOTE!! Which leave the modem in tact but changes everything else. But I don't have an active TMO SIM too check to see if I can get LTE on the AT&T GN2!!
But I get it..on one of them:thumbup:
