Will T-Mobile S4 work on AT&T S4 and vice versa.. - T-Mobile Samsung Galaxy S 4

Hello,
I'm in a dilemma where I have personal T-Mobile service, and AT&T service with my work. I want to purchase the variant of the S4 that will have the best compatibility with both networks (including HSPA, HSPA+, LTE). T-Mobile LTE has also already gone live in my market.
It seems the international i9505 support's T-Mobile's LTE bands (AWS 1700 / 2100 MHz LTE)
However, AT&T's variant (SGH-i337) supports AT&T's LTE (LTE 700 MHz Class 17)
Can anyone confirm if the international model also supports AT&T's LTE 700 MHz Class 17 Network?
Thanks!

From TMO spec sheets, it shows that it supports AT&T LTE bands. There are threads on this already.

[Q] Does T-Mobile have two versions of the GS3?

I'm trying to buy a GS3 from T-Mobile, but I need it to have AWS 1700/2100, because I'm on Wind Mobile in Canada. But looking on eBay it shows the GS3 to be GSM with no 1700 AWS frequencies. Although, GSM arena does show the following frequencies for the T-Mobile T999:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1700 / 1900 / 2100
But on TMobile's website it doesn't list 1700/2100 AWS, but it does show Band IV (AWS) which I believe is supposed to be 1700/2100 AWS. This is how it shows on the T-Mobile website:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
But on ALL eBay listings it doesn't list Band IV (AWS) or 1700/2100 AWS. It shows the following:
GSM/GPRS/EDGE 850/900/1800/1900 (Quadband) HSPA+ 850/900/1900/2100
Can someone clarify if the T-Mobile version really has the 1700/2100 AWS frequencies? Appreciate all the help.
Yes. T-Mobile uses the 1700/2100 bands for Their HSPA+ network. It should work fine for you.

I think the OP's point was that all eBay listings have the phone listed as: GSM/GPRS/EDGE 850/900/1800/1900 (Quadband) HSPA+ 850/900/1900/2100
If indeed all eBay listings show this, then those phones would not work on Wind. There is no 1700 in that frequency band description. So unless all these eBay sellers got the specs wrong (which would be a really big coincidence) or if indeed TMobile has more than one version, then those Tmobile USA branded phones will not work on Wind Mobile.
Update: I just took a quick look on eBay and all listings do indeed list the phone specs without the AWS 1700 spectrum. But Tmobile's website does show the UMTS Band IV listed in the GS3 specs. And Band IV is another name for AWS 1700/2100. But hey, if every eBay listing is not listing the AWS 1700 spectrum in the specs, then maybe T-Mobile does indeed have 2 different models.
They don't. (well they have 16gb and 32gb versions but, that's irrelevant to this discussion) Ebay sellers often cut and paste descriptions in their listings leaving people confused
T-Mobile uses the 1700/2100 bands. I should know, not only do I have THAT version of the SGSIII....but it must have those bands to get HSPA+ on T-Mobile's network. That's one of the reasons AT&T and most, international versions of phones (One X tegra 3 version comes to mind), ONLY GET EDGE.
The other option is that the listing is for the international SGSIII which IS NOT compatible with T-Mobile's HSPA+ network.

[Q] Using T-Mobile Galaxy Note 2 on AT&T's LTE (Will It Work if I do the Following?)

[Q] Using T-Mobile Galaxy Note 2 on AT&T's LTE (Will It Work if I do the Following?)
Can't you flash an AT&T firmware on a T-Mobile Samsung Galaxy Note 2 handset to get the necessary AT&T LTE Frequencies since the LTE radios on both AT&T's and T-Mobile's Note 2's are the exact same? Or is unlocking the Note 2 via T-Mobile more than enough to take advantage of AT&T's LTE Network?
Tread carefully, I'm currently trying to get my phone out of a rather nasty bootloop/corrupt IMEI situation after trying just that earlier today.
But I did get it to work, even pulled 35 Mbps on a speedtest.
Things went to hell after trying to revert back to the T889V modem. (In case I needed the AWS HSPA, for proof of concept and also warranty purposes).
so our phone's LTE modem is compatible with AT&T LTE bands? sweet.
^^^ Did an LTE status show up when you ran the Speedtest; this was with an AT&T Sim, right? ?

Virgin Mobile Canada LTE SIM (previously confirmed working in an Galaxy S III), and yes the LTE icon showed up immediately, Speedtest says LTE too, and the speeds are way beyond what I had with HSPA in the same location.
Doesn't AT&T's LTE run on different frequencies; so will T-Mobile's Note 2 match with AT&T LTE Frequencies after flashing to AT&T's Firmware?

Tmobile's T889 supports LTE on AWS and 700 (band 17).
AT&T's i317 supports LTE on AWS, 700 (band 17) and also on 850 and 1900 (band 2).
So yes, our phone has the ability to work on SOME of AT&T's LTE network, but not all of it; it will just depend on which frequencies they're using in your area. I believe AWS and 700 are new for AT&T, so they're probably fewer and more between at the moment, whereas their current network is mostly 1900 and 850. Not sure what kind of upgrade they have to do to switch their old HSPA 1900 towers to LTE support.
Silly question, so is a tmobile note 2 capable of handling AT&T's LTE network on the 850 and 1900 bands; is this something controlled by software, or a hardware limitation, I thought the Qualcomm radios on the AT&T variant and tmobile variant were the same.

[Q] LTE bands on GS4

Hi developers,
I am a new member here, so please forgive me if I am asking dumb questions...
I recently read on the US Samsung website about the T-mobile version GS4 that it has 6 LTE bands on it: 1/2/4/5/7/17, which correspond to 2100 1900 1700 850 2600 700MHz respectively. Since T-mobile website did not specify what bands their GS4 will have, I assume it will be the same as the T-mobile version GS4 on the Samsung website.
Samsung website:
LTE: Bands 1/2/4/5/7/17;
HSPA+/UMTS: 850/1900/2100MHz;
GSM: 850/900/1800/1900MHz
T-mobile:
UMTS: Band I (2100);
UMTS/HSPA+: AWS Band IV / 2100 / 1900 / 850;Band II (1900);
Quad Band GSM;
LTE (????)
My questions are:
1. Since AT&T uses LTE bands 1/4/7/17, which are also covered in the Tmobile GS4. Technically, does that mean I can use Tmobile GS4 on AT&T WITH LTE network?
2. I will be traveling to Asia and the country I am going uses 2600MHz (Band 7) as its LTE band, does that also mean I can use LTE on their network too?
Thank you so much again honored developers!

[Q] Which version phone to get? International or unlocked T-Mobile?

Hi,
I've been reading these forums for a few weeks in anticipation of getting a Samsung Galaxy Note 3 and am still confused(especially with the news about each version of the phone being region-locked).
My intention is to use the phone here in the United States on T-Mobile and also in Philippines(via a local SIM card purchased there). I've heard that the International version(N9005) only supports 2G(Edge) on T-Mobile here in the United States. Does that version support all bands(2G, 3G, 4G, 4G LTE, etc.) in Philippines?
Does anyone know if the T-Mobile unlocked version of the phone will also support the same bands used in Philippines when I take it there?
Because it seems in my case it might be better to get the T-Mobile unlocked version of the phone so I could possibly still use it in Philippines at their maximum available speed in addition to being able to use the maximum speeds on T-Mobile's network here in the U.S.
Also, are there any specific pros and cons with each of the two versions of the phone?
Any info would be very appreciated.

Here's what I know about Philippines (source):
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 850, UMTS 2100
4G capabilities LTE 850, LTE 1800, LTE 2100
[Info from your link]
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 850, UMTS 2100
4G capabilities LTE 850, LTE 1800, LTE 2100
Thank you for your response and the helpful link. It looks like both the International(N9005) and T-Mobile unlocked versions of the phone will support both of the 2G and 3G bands. For the 4g band, the respective phone covers the following Philippines 4g bands:
International(N9005) version: LTE 1800, 2100
unlocked T-Mobile version: LTE 2100
What I'm wondering is if it will be possible to use the unlocked T-Mobile version of the Note 3 in Philippines using a local sim purchased there? If so, then it seems like it will be more beneficial to purchase that version of the phone since it will allow me faster speeds(4g) while here in the United States while also allowing me to use their LTE2100 band for 4g speeds.
Thanks for any insight you can provide me.

Definitely T-Mobile version unlocked.
Not just it has penta-HSPA, but you can use wifi calling with T-Mobile SIM attached to keep using your US number under wifi mode (and save you from roaming).
Do you guys know, if the unlocked t mobile version will allow us to use it with local SIM card when we are travelling oversea?

International LTE coverage and phone bands

band 7 2600 Supported by i337 and m919 band 7 used in Europe and Canada
The i337 (AT&T model) does the same LTE bands as the T-Mobile model. It only lacks AWS HSPA+ (3G), which the mod in this thread enables. I would have gotten the M919, but T-Mobile doesn't sell the 32GB model, plus AT&T variants are generally cheaper.
No model sold in the US (including the i9505G Google Edition) will do 800 or 2600 MHz. The i337M does though (Rogers Canada). Europe uses completely different LTE frequencies than the US.[/QUOTE] END QUOTE

The m919 according to this supports 2 and 5 bands that the i337 does not, i am new to this but as i said i picked this phone for international use aswell and would like to know the truth. But according to my information, Vodaphone in Germany uses to main bands 7 and 20. 7 Being the one that the US variant could receive.
since the I337 is basically the same in Canada, i looked up Bell
Bell :
Bell Canada 1700 4 FDD September 2011 [75][76]
Bell Canada 2600 7 FDD March 2012 [77] available in Kitchener, Waterloo, Cambridge and Toronto for additional bandwidth.
Both 4 and 7 are support by both devices, since 7 is on freq 2600mhz in Canada and is the same I337 as AtnT would it not be right to assume that the phone could get band 7 in europe? It is true that AtnT does not use those bands in the US but that does not mean the phone cannot support them. Furthermore i picked the M919 because of its native AWS support and the 30$ 5GB 4GLTE Tmobile Plan BOYA talk about savings..... I am curious to know if im correct, my research lends me to think I am. Europe uses mostly band 3 and 7! 7 Being the one you want!

GPRS/EDGE compatibility
850/900/1800/1900 MHz
They list there LTE in MHz but i believe 2600 IS band 7 which the US variants support. My confusion is that AWS is listed in there LTE part and in the US its under the HSPA part. A little clarification and first hand experience with internation use of US variant S4s would be great for poeple who have trouble getting good information from the other side of the world!!
Worst case tho im sure you can always get texting and calling and stick to Wi-Fi while travelling, but to us super-users, thats like going back to dial up.
Lol why are you copying and pasting my posts? As for your question, AWS is used for LTE on T-Mobile (and in very few areas by AT&T, which is why their devices also do AWS LTE). However, AT&T requests that AWS HSPA+ be disabled on their devices because they only use 850/1900 MHz for HSPA+ and it would only benefit those looking to switch to T-Mobile if they left that 1700 MHz band activated.
