Wait, I have GT-i9300 with Straight Talk SIM which connect to AT&T using Tracfone operator. So I can't use any of the ROMs ? That doesn't sound right... I currently get nice reception after changing the APN and using the stock ROM.

OK let me explain this as simply as possible,
Gt-i9300 = OK.
Anything else = not OK.
OK?

No, the US cellular one is the snapdragon version, and it is CDMA too, so pretty much the same as Verizon.

[Q] Can the AT&T Note be unlocked for T-Mobile?

Can this model by unlocked for T-Mobile very easily like most Samsung Galaxy phones?

Probably, but it'd probably have crippled mobile data speeds since these two carriers use different frequencies for high speed data.

If its anything like the Skyrocket, which it is hardware wise then it could possibly have access to T-Mobile 3g with a modem flash. Let's hope so.

There's no guarantee... Have to look at the specs to find out bands on the phone.
EDIT: current specs that I found on gsmarena.com say that it DOESN'T get UMTS 1700mhz, which I believe is necessary for 3g/"4g" on T-mobile. So possible, yes, but with crippled data speeds.

lol, how do you think it gets LTE? 1700mhz. Like the Skyrocket, good try.
Like I said, we will have to wait and see if the s2 (t989) modem will work on it. Cross your fingers everyone.

Um, ok. LTE is now apparently the same as HSPA+ now. I didn't know that.

Lol, then how does the Skyrocket get T-Mobile 3g? Haha, sorry man.
I'm not here to argue just saying that because the hardware is similar it could work. But again, there is no guarantee this trick will work with the At&t Note

Why not keep the international note? It'll have T-Mobile 3g, and will have much more dev support than the ATT version. Seems like a no-brainer to me seeing as you'll have one in your trades.

Right now the international one does not have 1700 for T-Mobile 3g. Also the international one will never have LTE.
And look at the AT&T S2 and skyrocket. They both have good dev support.

International does not get 3g on TMobile. There is a development bounty of $910 right now to try to get a dev to come with a work around. It shows 1700 but does not work.

That bounty will NEVER get paid. The 1700 is for GSM, which is for voice and data up to Edge. The phone doesn't have hardware to receive 1700 UMTS, which is needed for 3g/"4g" on T-mobile USA.

Are you sure? I heard it differently.
My family possibly be going to Verizon, and I look around. Most if not all the info I seen so far said no.
If there is a way, I want to know. Since I have the SGS2.
Any unlocked phone can be used on any network so yeah you can use it on Verizon

Yes and no, because Verizon uses cdma and not gsm and your phone is gsm based you will only be able to use voice and 2G Data, 3G will not work with your phone.

Guys seriously? Verizon doesn't use SIM cards in order to use a phone on their network you have to use a Verizon branded phone! Sorry no unlocked phones! Sheesh feeding him wrong information could waste him a lot of money!

Because it doesnt have the TMO radio band for TMO's HSPA+ (wait I forget this is the international section, are you talking about TMO US?) If It's TMO US that is why. the international doesnt have TMO's AWS band for their HSPA + so you will be stuck on 2G data speeds
Because the international S3 can only get 2g speeds on T-Mobile.
you can get hspa+ if you use it on at&t or if you are in one of the areas where T-Mobile has refarmed the 1900mhz frequency for 3g but I think I saw someone mention here yesterday that there are only 5 areas so far but they should be more widespread in the next few months.

No.
Its a hardware thing, not a software thing.
You have three choices, wait for 1900mhz to be refarmed to 3g in your area, change to at&t or put up with 2g speeds.
Simple as that really.

I can only imagine how you feel being stuck with that constantly, when I lose signal with my carrier (3 Ireland) it roams onto vodafone Ireland and I only get 2g speeds then, its unbearably slow.
When I was in America a few months back I got a tmo sim in new Orleans and had 3g speeds but when I went about 5 hours north I was roaming on at&t and they don't let you use data at all when roaming, a-holes!

Is Straight Talk a good at&t Alternative?Other Carriers?

Im on t-mobile and this constant data drops and crappy signal in my house and everywhere u go is intolerable. I really don't wanna sign a contract but heard.good things about straight Talk. So i need advice or current user input on this matter. Or recommend me to something worth checking out. Thank you.

StaightTalk seems pretty good for at&t users who want to change carriers with minimum fuss. Your at&t note won't need any rom or modem flashing. But, you will have to unlock it and manually input the APN settings.

It runs on AT&T's HSPA network. So it's the same as that. You won't get LTE though. That currently only for AT&T.

If you have an AT&T phone and plan on using ST AT&T then you don't need to unlock your phone! I'm using the GNote on straight talk AT&T without it unlocked.

It will work. If you mean on a telus network, the wifi calling (do they have that?) likely will not, and you'll probably need to flash a different modem. I know nothing of Telus, though.
Hardware wise, though, it will work just fine.
My wife is using MetroPCS as well. Her phone is from CA Telus. Mine is from att. Mine was i717 before I flashed a TMobile ROM. Hers,is the i717d.
