Hey all. I am looking to purchase a galaxy s 3. Would a t mobile galaxy work over seas or do I need an international one? Thanks.
Yes, it will work. The T-Mobile S III has quad-band GSM/EDGE/HSPA+ support.
So in that case id be better off buying one out of contract and using one of the Korean providers when I go over seas? Do you know if the international one would work?

Either version will work. Both are quad-band GSM/EDGE/HSPA+. The difference is that the T-Mobile version supports 1700 MHz HSPA+, while the international version ditches that, and supports 900 MHz HSPA+ instead.

What exactly does 1700 MHz HSPA+ and 900 MHz HSPA mean??? Everything ive found says GSM phones dont work but those were outdated by a few years. Did GSM phones just start working there recently?

You mean it's penta-band has the extra aws band and it should work in korea if they use the same bands like europe

It's not penta-band. It doesn't have 900 MHz HSPA+ support.

Those are just bands that the phones support. And GSM is a world standard, it should work in Korea, and HSPA+ should work too as it supports the 2100 MHz band.
Wifi calling is an option too.
So I heard LTE is backwards compatible with GSM and HSDPA + My carrier supports AWS band 4. Will this work? Has anyone tried it?
So you're basically asking if the AT&T Optimus G will work with T-mobile's 4G Network, right? The answer is NO. Or at least not by default. That's because, even though the phone has the correct band (1700/2100), you would still need the correct radio to be able to use that specific frequency (again 1700/2100) with your carrier. Much like the AT&T Galaxy Note I717. It supports the 1700 frequency, but in order to have that working band with Tmobile, we had to flash a Tmobile specific baseband/radio from the Galaxy s2, Galaxy S Blaze 4G and/or Tmobile Galaxy Note to be able to use the phone on the 1700 freq. So in this case, Unfortunately, Tmobile won't be releasing the LG Optimus G, so there won't be any radios available to use. But, the LG NExus 4 actually has the exact hardware specs or SOC as the LG Optimus G, so a radio/baseband port might be possible.
I hope this post made sense to you.
So what is the difference than taking a locked phone, unlocking it to another network that shares the same GSM frequency?

Actually the two networks don't share the same GSM freq. Yes the AT&T LG Optimus G does have the AWS 1700 band in the hardware, but it is not enabled by default in the software. In order to enable the AWS 1700 freq, you'll need to use/flash the correct radio that carries the AWS 1700 freq. Like i said in the earlier post, one might be able to possibly port the a radio/baseband from the LG Nexus 4. Since it supports all pentaband frequencies.
So why would they disable it if the carrier uses 1700/2100 for LTE? I'm still not understanding its limitation
The carrier I want to bring it to uses AWS 1700/2100 3.5G.
Are they selling a phone that doesn't work with LTE on there network? Or can the phone only do 1700/2100 in LTE ?

It's not that the 1700/2100 bands are disabled. They are very much enabled but the radio is set to use them for LTE.
So you are saying even though LTE is backward compatible the band installed is software limiting the hardware to only allow LTE 1700/2100?
Nuxtux said:

LTE phones are backwards compatible because they support other bands for HSPA and GSM. For example, a carrier using 1700 MHz for LTE may use 850 and 1900 for HSPA but the 1700 will only work with LTE.

You somewhat got it. It is the same problem with AT&T's HTC ONE X. The phone as the 1700 band for LTE, but when used with Tmo it only picks up 2G using the 1900 GSM. But with Tmo merging with Metro PCS, and partnering with Ericsson and Nokia Siemens Network, the H+ 1900 Spectrum will be available everywhere very soon. I read an article on tmonews.com that it should be done by the end of this year.
maybe the Canadian Telus version would work with T-Mo's AWS
it'll work you'll have to use the modem firmware from the N4 in order to use hspa+

Any one got this one working? Got my Att OG, but edge is very slow. the T-Mo refarmed areas are OK though
Hi there,
Can anyone confirm for sure and tested the following question:
How many bands for GSM, HSDPA and LTE does the T-Mobile Galaxy S4 (M919) have? Are they the same bands as the International S4 LTE (I9505)?
Based on the wikipedia page for Samsung Galaxy S4, the model I9505 has more LTE bands than the T-Mobile M919 version, is that completely true and technically proven?
Most of the websites state that the M919 and the I9505 has the same bands for all GSM, HSDPA and LTE.
I appreciate if someone can lead me to the ultimate answer.
Thanks.
Tmobile uses AWS for 4g LTE which requires 2100/1700 frequency. The GT-i9505 only supports 2100mhz i believe, which is not enough.
I think the GT-i9505 supports one of the several frequencies that Tmobile uses for HDSPA, so HDSPA coverage may be a bit spotty with the phone. This was referenced off the top of my head, but I had done some research online about this before as I had similar questions as you.

You can find all the information on the Wiki page: https://en.wikipedia.org/wiki/Samsung_Galaxy_S4
I9505 lacks the 1700MHz LTE band which is needed in T-Mobile LTE.
That's weird, I can swear that wiki page had different information yesterday about the I9505 LTE bands

Hey so looking at the wiki that you guys posted up there it says following for the tmobile version: 700 MHz (Band 17), CLR, AWS, PCS, IMT, IMT-E
now i somehow got my hand on one of these devices in europe for rather cheap and totally new, so im confused now what these CLR, AWS, PCS, IMT, IMT-E are, does any of these stand for any other than the 700mhz band? like 1700/1800mhz? or in other words, is it possible to get lte to work in europe with the tmobile usa s4? Can the modem perhaps be flashed with an i9505 one and than get the additional bands or is the hardware actualyl that different (as in antennas and amplifiers)?
Its not really a dealbreaker for me as LTE in my country is quite some time away but still, would like to know.
thanks
In simple words, the LTE bands are (not in order): Band 1 (2100), Band 2 (1900), Band 4 (1700), Band 5 (850), Band 7 (2600), Band 17 (700), so we have the LTE bands available for the T-Mobile version: 700, 850, 1700, 1900, 2100 and 2600.

sorry for asking it again, but that basically means the tmobile version has most bands that are used enabled? just have to figure what bands are being used in my country... thanks really
edit: checked the bands here naturally its 800 and 1800, so my question remains, can i somehow flash the phone to work on these?
Check the picture attached, this photo is from the original T-Mobile US Samsung Galaxy S4 (M919) box.

No, you can't flash a I9505 rom to a M919 device, if you do, you will brick it. The best option for you to get 800 and 1800 frequencies is to go for the GT-I9505, it's the Samsung Galaxy S4 LTE version, and it has the following bands for LTE Cat 3 (800 / 850 / 900 / 1,800 / 2,100 / 2,600 MHz). This is the official Samsung page: http://www.samsung.com/au/consumer/mobile-phone/mobile-phone/smartphone/GT-I9505ZKAXSA-spec

Yes, it seems that the I9505 has LTE bands for each region, it's not dedicated for America (North, Central and South), it also support Europe and Asia, while it doesn't contain most bands for a specific region, it's a world phone, unlucky doesn't fully support T-Mobile 4G UTMS network (1700/2100), but still a good option for those who travel to other continents.

Flashing just the modem doesn't work either?
I haven't tried flashing modems into another devices that don't correspond to their own. I can't help you with that answer at this time

Question...are all those other things i've been hearing about other ppl successfully getting 4g reception after doing something to either with the aws band's, or to the software true? does anyone know for sure? i'm very thankful for any input, as i've been hearing so many conflicting things when it comes to the i9505 and getting 4g service with t-mobile, i just want a proven answer :/

I bought my S4 T-mobile (SGH-M919) in USA. And it is fine working in Spain with 4G. But when i have upgraded it to Marshmallow then only works with HSPA(H+) as better. Change baseband? i am not sure to do it...mmmm
Ordered this phone off of amazon thinking I was getting the standard unlocked version. Turns out I got the 2.5GHz Asian model. Is there anything I should be worried about in regards to T-Mobile compatibility?
Might not have AWS enabled....check for it 1700 band

No AWS and no 1900. Looks like I'm gonna have to send it back.

Are you sure it's the Asian model? Both the Asian and EMEA models can connect to 2600 MHz LTE.
The Asian model can do 700 MHz LTE (unlike the EMEA model), but T-Mobile will not begin rolling out their 700 MHz network until later this year. In any case, you'd want a model that picked up AWS so you can use T-Mobile's nationwide LTE band.

Keep in mind that AWS consists of both 1700 MHz (uplink) and 2100 MHz (downlink). If you have a carrier that has either 1700 or 2100 (but not both), the phone might detect the carrier, but wouldn't be able to use it.
