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] 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)

thanks.

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

So how does one unloxk that?

Make sure your using the right APN....... if your not using the right APN you won't get lte
Sent from my GT-N7100 using xda premium

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

ATT Note 2 work on Straight Talk ?

Was at Worst Buy today, they said would price match any online price for the Note 2, plus offer me free insurance if broken, or any issues.
I was gonna get the true international Note 2, but worried if it has issued or warranty problems, it would be much easier to just go back to Best Buy than to have to mail it off, out of the country.
So, that being said, I am on Straight Talk, I hate being raped by the carriers and handcuffed into outdated contract system. Would the ATT Note 2 work on my Straight Talk SIM ? Or does the phone need to be unlocked first ?
I never unlocked a phone before. But I always root and install custom ROM the first day I take phone out of the box. Does rooting a phone, automatically unlock it too ?
And how bout HSPA+ ? Straight Talk doesn't do LTE yet, just HSPA+ I know the ATT Note 2 is LTE, but does it also have HSPA+ too, or just slower 3G ?
Sent from my HTC One X using xda premium

You would have to unlock it, either buy scrounging a code or going to the carrier and asking for one. Rooting doesn't automatically unlock the device. As far as 4G I really dunno, but I'm sure someone will tell you.

I believe you only need to buy the att version of the straight talk sim. No need to unlock. Then you go on their web site and get the APN.

Thanks, so I am currently using the ATT SIM on Straight Talk. Just pop that in the new Note 2, and it will work right out of the box ?
What about HSPA+ ? Straight Talk doesn't have LTE. Does the ATT Note 2 have HSPA+ 3G besides LTE ?

It is not the sim from att. Its a straight talk sim made for att phones. You have to order them online. It uses att network and you would get everything except lte.
https://www.straighttalk.com/ShopSims is where you order the sim and there is more info on the service on the site.

On my international One X, I am using Straight Talk with the ATT SIM. In the Straight Talk package, there were three sims to choose from. T-Mobile, and two ATT, one regular size, and one micro/mini, which is what I am currently using.
So can I just take this mini ATT SIM from Straight Talk, and pop it in the ATT Note 2 from Best Buy, and it will work ? I don't need to have the phone unlocked ?
Thank you

Its already been answered and yes ITS BEEN A LONG time since ive even seen a UMTS on my phone. and also HSPA+ is still 3G.... Straight talk Uses Edge,3G, and 3.5G which is HSPA+
Also if the Note 2 only used LTE then people would not be buying it cause not all AT&T areas are LTE...

I am more than happy with 3.5G HSPA+, plenty fast for my phone needs, I just wasn't sure it was included in the Note 2, for some reason I thought was just standard 3G only and also LTE.
Most the time I am in a WiFi area anyways, at Home or Work Office, so LTE not a deal breaker for me.

Good point, thanks for the answer.
Last question, since I am using the ATT Sim for Straight Talk, is there even any point to have the ATT Note 2 unlocked ?

I would, just in case your are in area where there is no at&t service and are on the Edge network. Not only that but unlocking is free!!!

4G data on an ATT GS3

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?

Maybe you should try posting in the ATT S3 forums? I'm pretty sure that most people here have the TMO variant, while you are looking for tweaking of the ATT variant.

Don't flash a T-Mobile modem, it will brick. T-Mobile and AT&T use different frequencies for hspa+ in most places, and the AT&T version doesn't have the hardware to pick up the most used T-Mobile frequency I believe. So you're probably stuck with edge

You ARE stuck on edge.... I know it sucks. unless you are in a refarming area http://www.airportal.de/ , (major cities) your AT&T S3 1900/2100Mhz high speed data (4G) band will not work on T-Mobile's 1700/2100Mhz networks. I would sell it on e-bay or craigslist and got your T-mobile S3 again. or get the T-Mobile S4 after you sell your att S3 :cyclops:

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:
