[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?

T-Mobile / Simple Mobile / Galaxy S3 ?

Until recently I have been with Sprint. And I am located in South Florida.
I am considering going with Simple Mobile as I'm told that T-Mobile has one of the best data speeds in this area. And I want to get a Galaxy S3 as the phone to use with this service.
Can anyone here advise as to whether this would work with Simple Mobile (I called them but they won't say anything only that they don't don't support it - meaning they don't sell it so don't bother them), at what speeds?
I also assume that I must get the T-Mobile version of this phone. That seems quite difficult unless I want to pay a big premium to T-Mobile, who charges much more than say AT&T for their version. So if anyone has any suggestions where I can get one (I would prefer a store, not eBay)?
Thanks

try the xda marketplace
edit: nvm just saw you dont have enough posts.

I read that the Sprint variant of the S3 would work on T-Mobile. You just have to unlock the phone I believe.
Sent from my S3

I remember negri sells the phone for $599 unlocked. That's the cheapest I've seen for the TMobile version. It's not cheaper by much but it's unlocked and you may save on taxes.

Sprint is cdma and T-Mobile is GSM. How are you going to stick a sim card in that sprint phone?
Sent from my SPH-D710 using xda app-developers app

My wife is using it on Simple Mobile. It works great.

Simple Mobile is a Mvno of t-mobile so you don't need to have an unlocked T999. Just change the apn. A's far as speeds. I live in Central Florida and I get the same speeds as t-mobile. I recommended. As far as where to buy the phone. I went to t-mobile and paid $599 for it. Haven't really seen it cheaper.

It does have a sim slot but it's not user accessible.
It's hidden behind the plastic under the battery.
Sprint has taken this approach with all there LTE devices.
The only exception may be the Photon Q since it's touted as being a global device.

To get 3g you cannot use T-Mobile I would recommend getting a straight talk SIM card that uses att network. Or any other non T-Mobile prepaid plan.

If you need to use your original carrier whilst in the states the only option is to purchase an international plan from your original carrier. I remember sprint offered it as an extra 30 a month. But you only paid when you needed it.

A model question.

Hi everyone:
Im thinking of migrate from Note I to Note II. Im from Argentina and i have the possibility to buy a Note II in Miami.
My operator here is Movistar Argentina and the question is, are many models of Note II? here i must use the gsm chip.
Are there any model of Note II without the operator sim that obviously i must not buy?
Thanks for who can answer.
Regards.

Just make sure it's GT-N7100.

Mhhh, sorry i think that my question is not right.
When my brother lives in EEUU, he has a Phone (simple phone) that has Mobile line but without simcard. He cant change the mobile line, because there no simcard. The mobile line cames with the Phone.
Because im thinking to buy a note 2 in eeuu, i dont want to buy a device that cant use in my country. Then, there are any model of note 2,without simcard but with mobile line built in? That obviously dont work for my and must be care to dont purchase it?
Thanks again...

I do not know of a galaxy model that comes without sim slots. My guess is that thr simless phone is not a smartphone? It used to be like that in my country as well but sim cards had to be used once smartphones were introduced.

If what I read is right I know why that thread doesn't work for you. Metro is CDMA and doesn't use sim until Tmo phases it out and switches them to GSM. You don't have a sim card? Is that right?

You cant unlock metro phones, the s4 I heard was supposed to support gsm and cdma and metro and tmobile are not phasing out each other ....there new upcoming devices are gonna be dual cdma /gsm and back each other on data where metro gets weak data tmobile gsm will cover and vise versa where tmobiles weak metro cdma will pick up coverage. .
Im not sure if the metro s4 has this feature yet
But thats the plan for this metro tmobile merge.

Just to let y'all know:
Yes, the S4 is a GSM phone that uses both the GSM Tmobilr network and the LTE of MetroPCS, giving u the best of both worlds. When u get it thru metro u also get the best price (50 cheaper on the phone and monthly bill is lower too).
Since it is a gsm phone it can be unlocked.
To answer another question, yes u can use any unlocked T-Mobile or att device on metro at this time. The prices of those phones would still be the same monthly bill as a standard metro 4g phone (40 or 50 or 60)
Also, Metropcs does NOT unlock phones, but they accept unlocked phones.
Hopr this clears things up a bit!

Metro should unlock for u, but will put up a fight no doupt, unless u tell them ur going abroad, and or have a second sim to use. All the gsm carriers csn unlock there own phones. There are unlock sites that will do the job to. the cheaper sites take long time, anything under 10-15. Usually 20-24 csn do within 6-8 hours.
