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?

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.

Its called a pentaband phone for a reason.
Sent from my Galaxy Nexus
A phone could an infa-band, but if it hasn't got AWS 1700/2100, it's useless to me. Other forums, sites and Wind have said the T-mobile (AWS) version is the only one that'll work. If the penta band version includes AWS frequencies, that'll be the reason it works.
Look up pentaband. There is no T-Mobile galaxy nexus.
It will work. Not really sure how that isn't clear by the number of people using the galaxy nexus on T-Mobile.

There are only 5 3G frequencies that cell phones use (outside of Japan): 850, 900, AWS, 1900, 2100. If a device is called "penta-band", that means it supports networks that work on any of those 5 specific frequencies, not 5 random frequencies. With tri-band and quad-band devices, it's a different story, as there could be multiple versions of devices, but a penta-band device covers all the bands.
On a separate note, thread move to Q&A.

So Galaxy Note 2 has now got 5 models to be released shortly, here is the breakdown
International : GT-N7100
Verizon : SCH-I605
TMob : SGH-T889
Sprint : SPH-L900
AT&T : SGH-I317
Thanks to Evan
AT&T : 850 cellular/1900 PCS GSM/UMTS & 700MHz (Band class 17) LTE
Verizon : 850 cellular/1900 PCS CDMA/EVDO & 700MHz (Band class 13) LTE
Sprint : 800 SMR/1900 PCS CDMA/EVDO & 1900MHz LTE
T-Mob : 1900 PCS GSM/UMTS & 1700/2100 (AWS) UMTS
Seems like they will all have Quad Core Exynos with a seperate LTE chip
My question is does that mean we will be having five different model forums, or is it possible to have only the current one for all the models, since they are pretty much the same Exynos + LTE.
I hope not......i hope they each have their own

Interesting question.. I think that as far as you dont flash a different radio(assuming that the main difference its the band) you would be good to go.. an example of this happens on the Gtab 7+ variants.. mine its 6800n(different band for south america) and i can flash any rom from the other variants 6800/6800h no problem.. just keep my radio..
There is two international versions:
N7100: 3G only
N7105: LTE
And yes they will most likely get the same forum with seperate development sub-forums.
One thing I wonder about, here in Sweden the LTE frequencies is 800/900/2600 MHz.
It means that when we get LTE it will be different from the international version and developer support will be non-existent or can we flash international roms if the only difference is LTE frequencies?

Each carrier wants to have complete control on what is in the phone and what they want to cripple. I'm heavily considering the International version this time but will wait for all the details to come first.

i have never bought an international version either but if it comes out sooner i will since i would like to travel a lot...
will the international version for any reason not be as good as the eventual verizon version for me in regards to anything....4g speed, roming, etc...
thx!
No need for me.to get the international versions anymore I guess,since the processors are the same.

No, there is also fragmentation between AT&T and T-mobile versions. They use different frequencies for 3G (HSPA+) so an AT&T phone will not work on T-mobile and vice versa. You'd need a pentaband phone (e.g. Galaxy Nexus) to cover AT&T, T-mobile, and international gsm networks.

I'm VERY concerned about buying this phone now. T-Mobile have only listed LTE bands 4 & 17 on their site.
International
Quad Band GSM; LTE: 4, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
What in the eff?
Des just answererd this question on Twitter: https://twitter.com/askdes/status/581568102015569920
It has:
GSM - 850/900/1800/1900
UMTS - B1/B2/B4/B5
LTE - B2/B4/B12/B17 with CA + B3/B7 roaming
This is the perfect T-Mobile phone.
So the T-Mobile version does not have 1700, and is therefore identical to the other models? Do we know if it includes wifi-calling, or if we would be able to flash the T-Mobile ROM onto the unlocked dev version?

It does have 1700! That's Band 4, and for both LTE and HSPA.
The T-Mobile version also supports WiFi calling and texting. I have no idea if the T-Mobile firmware can be flashed to the unlocked version, but I don't see why it wouldn't be feasible.

T-Mobile (Des) confirmed: 2, 3, 4, 7, 12, and 17
AT&T lists: 2, 3, 4, 5, 7, 12, 17, and 29 (adds +5 and +29)
HTC Dev & Unlocked versions (per HTC on Twitter): 2, 3, 4, 5, 7, 12, 13, 17, 29, 30 (adds +5, +13, +29, +30)
Maybe the T-Mo phone supports more that could be unlocked, who knows. The extra bands aren't useful to me.

HTC has done this on the past couple of phones. Only the T-Mobile phone will do their specific bands (HSPA+). On past models I don't recall anyone getting the ATT/DEV models to work with those T-Mobile bands. I don't believe we ever found out why. Some speculated it was due to cost to license all the bands, or that it is actually different hardware. The M7 and M8 were both like that.
If you are on T-Mobile, I'd get the model specifically for them.

Oh yeah I remember my Dev version being like that. Fortunately, I live in an area that has been upgraded to mostly lte. This was actually beneficial for me and maybe others in the same situation because it actually saves battery life when the phone isn't constantly switching between edge, 3g/+, and lte. I'm sure many others have been in an area that's barely out of lte but still within h+ range and it's still slow as edge or even slower.

Yes, it is OK if you live in a major area that has lots of LTE. Here just north of LA, I get into the other bands pretty frequently.

They will not pick up the T-Mobile specific bands, which use 1900/2100 for 41bps speed. They will work with the T-Mobile LTE band.
Wow, still a mystery. I have the AT&T SIM Unlocked One M9 and I have a TMobile prepaid SIM and get Edge, 3G, 4G, LTE Band 2,4,12...I cannot find an app that shows the actual WCDMA (4G) Bands ? But, it notates 42 MBPS when it says HSPA+ 4G using Network Signal Info-Pro App..and also shows 384 Kbps when it says 3G....
So, seems Des is correct unless the Network Signal Info Pro app is wrong?
I turned off everything except WCDMA, and this is what I get being reported by LTE Discovery. HSPA+ @ -113. I have a ATT unlocked M9. I do have the T-Mobile 2.11.531.19 firmware installed as well as the T-Mobile rom.

Thanks but as I mentioned I cannot find an App that shows the WCDMA Bands to confirm. As you can see even LTE Discovery says N/A for DL and UL Freq...when on WCDMA...
The only App I can see that helps is Network Signal Info Pro...and unfortunately it is limited and shows me the below in my market;
HSPA+ 42.2 MBPS
HSDPA 7.2 MBPS
UMTS 386 KBPS
But, does not indicate which Band or Frequency ?
Anyone know of an App or Command that will show WCDMA Bands???

I have a T-Mobile branded M8 rooted, unlocked bootloader, and S-Off. I live out in the sticks and can only get 1900mhz LTE band 2 on my wife's S4 however, my M8 doesn't see band 2 because of the radio firmware.
Is there a radio firmware from another GSM M8 variant that I could flash to my T-Mobile branded M8 that would get me the 1900mhz LTE band 2?
Are you using the phone on a different carrier besides T-Mobile? If so, which carrier?
Also, Band 2 looks like its 1900 MHz, and band 4 corresponds to 1700 MHz (also known as AWS). So not clear which band you are looking for: http://en.wikipedia.org/wiki/List_of_LTE_networks
No. I am on T-Mobile US.
Sorry, I meant band 2 (1900mhz). Corrected in the OP.

That's really odd that the T-Mobile US variant doesn't include a band that T-Mob uses. But based on specs listed online, this is the case (doesn't support 1900 MHz Band 2 for LTE): http://www.gsmarena.com/htc_one_(m8)-6074.php
AT&T or Developer's Edition radios may be your best bet (AT&T uses 1900 for LTE).

I have a T-Mobile branded M8 rooted, unlocked bootloader, and S-Off. I live out in the sticks and can only get 1900mhz LTE band 2 on my wife's S4 however, my M8 doesn't see band 2 because of the radio firmware.
Is there a radio firmware from another GSM M8 variant that I could flash to my T-Mobile branded M8 that would get me the 1900mhz LTE band 2?

Looks like you and I are in the same boat. I was dumfounded when I found out a LTE capable phone I purchased from T-Mobile is not able to get LTE due to an unsupported band.
In any case, I have a similar post over in the [Q&A] [RADIO] Q&A HTC One M8 Radio collection for different model Models/CID's. See http://forum.xda-developers.com/htc-one-m8/help/qa-htc-one-m8-radio-collection-models-t2941210/page6
One guy mentions the AT&T radio would probably work but I would lose 3G connectivity in some areas. I'm going to have to look into that a little deeper.
Please update me if you find a solution and let me know how things work out. I'll do the same.

That's right. It occurred to me that the AT&T version lacks the AWS band (Band 4, or 1700/2100MHz), which T-Mob uses for HSPA+ (3G) in many areas. Its somewhat of an oddball band, meaning its not used in many places aside from T-Mob US, so its pretty rare to have this built into any radio that is not specifically T-Mob.

What a PITA. Why didn't TMO just go ahead and put LTE Band 2 in the phone in the first place. They knew they were pushing LTE in that band so why handcuff their customers. You can't make this stuff up!
Thanks for the information you have provided. It really is eye-opening. I'm still in the buyers remorse period as far as this phone is concerned and could return it. The problem is I don't know what phone to get without spending twice the money at this point. That is unless I want to move of an iPhone (Boo!!).
What a tangled web!

So does the developer version support the AWS band?

I don't know for sure but there is a 2014 article on Phandroid that states the Developer Edition is basically an unbranded version of the AT&T phone. So logic would say that if the AT&T version doesn't support it then the Developer Edition wouldn't either.

Dev Edition does not support AWS for HSPA+ (3G), according to this: https://support.t-mobile.com/message/359612

That was my original understanding as well, and for the most part true. However, its been pointed out on XDA (and specs online agree) that the Dev Edition is missing LTE Band 7, which the AT&T version does support. A minor difference that won't affect most folks (AT&T doesn't use that band), but a difference nonetheless.
Found much conflicting info on HSPA band support for the US unlocked/developer model.
htc.com says it supports 3G UMTS: 850/900/1900/2100 MHz. But is also says it supports 4G LTE: FDD: Bands 1,3,5,7,8,20,28, which is COMPLETELY wrong so i don't know if to trust htc.com.
Can anyone confirm the UMTS band support for this device? I am most interested in 900mhz UMTS because of trips to New Zealand where 900 mhz UMTS is often used.
Thanks!
Bump.

Really dont know about it, but as far as i know you can flash radio bands anyways, so look for it on the web or this site, i use dev with no prblems at all in mexico with LTE. =D

Is that really true?
I am looking into getting the HTC One M9 through AT&T but may switch to T-Mobile in the future.
As such I want a phone that fully supports both networks ...
I found a thread that it is supposedly possible to flash the AT&T phone to support developer ROMs but I can't find any information whether it is possible to also change band support. According to GSM Arena the AT&T version of the phone also supports LTE band 4 and 12 (needed for T-Mobile) but it doesn't support VoLTE on band 12, nor does it have 3G AWS (1700/2100), though of course there is a T-Mobile version of the phone WITH support for all of those.
Can I simply flash my phone so that I can (a) use CM13/AOSP roms and (b) so that the radio uses the proper AT&T or T-Mobile bands and tech?

WELL I DONT BELIVE cm13/AOSP WOULD BE BEST OPTION I FLASHED DVEELOPER 2.11 AND OVER IT VIPERONE 3.5.0 (WWE BASE 2.10) ANS WORKS FINE, AFAIK.... TELCEL BANDS (MEXICO) ARE FULLY COMPATIBLE AND PRETTY MUCH THE SAME AS ATT, ACTUALLY I FOLLOWED IN THE HTC M9 THREAD HOW TO CHANGE MY PHONE (ATT) TO DEVELOPER EVEN WHEN I HAVE TELCEL AND IT WORKED!!! =D YOU SHOULD HAVE NO ISSUE.

What I am asking is very different: AT&T and T-Mobile DO NOT use the same bands (e.g. AWS for T-Mobile) nor the same tech (VoLTE on band 12)

All this info is about LTE bands. I am curious about HSPA/UMTS bands. I would like to know what it supports out of the box, not what I can with mods.
Thanks!

Google is your friend.
And in case you didn't notice: I was asking about AWS and VoLTE since LTE bands are the same.

The T-mobile version of the M9 supports the most bands. The AT&T and Developer Edition are identical and are missing some bands needed for t-mobile LTE (Volte) support in some areas. Flashing different radios will not enable bands the phone does not have. Theirs more information in the T-mobile M9 forums

Thanks for the reply. I have checked GSM arena, plus anything else I could find on google. I don't see a listing for the unlocked/developer edition on this page. I see EMEA, Verizon, ATT and T-mobile.
And yes, sorry, I didn't realized there was an AWS for HSPA, i was just thinking about band 4 LTE on ATT which I think is AWS.

Thank you.
That's what I figured.
Sadly that means I won't get this phone.
Bump. Hoping someone can find a straight answer have been on the phone twice with HTC, even they can't provide a straight answer. I ever addressed them on twitter. No luck. Thanks in advance.
Bump!

It's pretty difficult to find out info on band support, and I have no idea why. It should be readily available...
Anyway, have a look at this: http://wireless.fcc.gov/hac_documents/150813/9135276_21.PDF
Based on that, there are four models sold in the U.S., which are:
0PJA100 (which appears to be the AT&T version)
0PJA120 (which appears to be the TMO USA version)
0PJA200 (which appears to be the Sprint version)
0PJA300 (which appears to be the Verizon version)
The AT&T model supports the following: UMTS 850MHz, 1900MHz and 2100MHz.
Now, that said, if you look on AT&T's site, they list their model as 0PJA110, so obviously either the FCC site is wrong or the AT&T site is wrong.
I happen to have the 0PJA110 model, which is also the Rogers model (so it would make sense that the AT&T version is 0PJA110 because Rogers and AT&T generally have the same devices, and their networks are generally the same frequencies). Based on HTC Canada's site, the Rogers model supports UMTS 850MHz, 1700MHz, 1900MHz and 2100MHz.
Now, for the assumption: From what I have read (but I haven't personally confirmed), the unlocked and developer models are the same as the AT&T model. If that is indeed the case, then you have your answer: No UMTS 900MHz support the unlocked and/or developer models (in fact, not UMTS support on any U.S. model).

I know this is a delayed followup, but I wanted to say thanks for this. I finally got HTC to confirm that UMTS 850MHz, 1700MHz, 1900MHz and 2100MHz are the official specs for the US unlocked edition(which, oddly, is marked 0PJA110 on the back).
I am pushing them for a refund for false advertising. I was so concerned that these specs could be wrong before I purchased the phone, that I did a chat with HTC and they assured me the correct specs were UMTS 850MHz, 900MHz, 1700MHz, 1900MHz and 2100MHz. Once they confirmed these specs for me, I purchased the phone. Now they confirm they told me wrong. Very frustrating experience.
I am waiting to hear back about getting a refund. I am hoping the come through, this is crazy.
