The AT&T or Rogers LTE Version of HTC ONE X has HSPA support on AWS&2100
(looks like lots ppl may not know this)
So AT&T one x works on T-Mo 3G network (wow~) Tegra FAIL!
and one more... The AT&T LTE version is originally called One XL (but now they call it X since idk)
Moreover, AT&T version looks like 549.99USD (Rogers version is $629CAD+tax)

It still won't have the 1700 band.

This has been discussed to death. The official HTC Asia page says the AT&T phone (by name) doesn't support AWS for HSPA. The LTE radio does but it won't work for HSPA. Do you have a link to share where someone has shown a Speed Test getting HSPA/HSPA+ speeds on T-Mobile U.S. with either a Rogers or AT&T One X? Until someone posts that this isn't confirmed and based on the published specs it probably won't be.
From HTC Asia:
HSPA/WCDMA:
•ATT: 850/1900/2100 MHz
•Asia/AUS: 850/900/1900/2100 MHz
GSM/GPRS/EDGE:
•850/900/1800/1900 MHz
LTE:
•ATT: B4/B17
•Asia/AUS: 1800/2600 MHz
From the Rogers site:
GSM Bands: 850/900/1800/1900
HSPA Bands: 850/1900/2100
LTE Bands: 700/1700/2100
From the AT&T site:
GSM/GPRS/EDGE - 850/900/1800/1900 MHz
3G/UMTS - 850/1900/2100 MHz
4G LTE - Band 4 and 17

http://www.htc.com/ca/products/htconex-rogers#tech-specs
Network
LTE CAT3 - DL 100 /UL 50
LTE: 700/AWS
WCDMA: 2100/1900/AWS/850
EDGE: 850/900/1800/1900
Clearly says AWS/2100 is on the list, also 850/1900
I'm getting it this coming weekend, so I will try
And some ppl on the XL forum says Rogers has 1700 hspa clearly written on the box,
It could be a software lockdown, Same as i717...
EDIT: Just saying on Rogers site, Nokia Lumia 7100 doesnt have 1700 listed on there either, but after unlocking, it works perfectly on Wind, so idk

HSPA might work base on spec
If you look at the Samsung Galaxy Nexus's spec, the 1700/2100 HSDPA is listed as "3G". I am using the international version with T-mobile and I am getting around 7mbps. This is definitely faster than 3G speed. Looking at the spec for one x, HSDPA 1700/2100 is listed as 3G also just like the Galaxy Nexus. Wouldn't this mean it would work with T-Mobile's so called "4G" HSPA?

The bands supported by the device has **nothing whatsoever** to do with the Tegra SoC, since the vendor uses a discreet modem with the Tegra 3 version of the One X anyway.

If this is true, than the weak signal strength and heavier battery drain are likely to occur just like they did on the G-Note. It'll be interesting to see how (and if) the One XL performs.

AT&T vs International bands
According GSM arena the AT&T version will support 3G 1700/2100 which is what Tmobile uses for its H+ network...so if you unlock the at&t version, it should be able to run on Tmo's "4G" right out the box without any needs to flash radios or what not right?
Here's the link to a comparison: http://www.gsmarena.com/compare.php3?idPhone1=4614&idPhone2=4320

Is it possible to flash a t-Mobile modem or tweek the one x to get faster speeds

Hello friend, I too am interested in getting the One X (international 32 Gig version preferred) but would consider AT&T's version. I was able to click around AT&T's website and I could not find where it actually stated 1700/2100 AWS however, it does say this:
"4G speeds delivered by HSPA+ (with enhanced backhaul) or LTE, where available" "4G LTE Band 4 and 17" -
And this:
"3G - UMTS850/1900/2100 MHz"

T Mobile has confirmed the reframing/refarming of 1900 from 2g to 3g but stated it was slow process (slower than Edge? lol).
Really want the One X...

It is a pentaband phone (850/900/1700/1900/2100) but on Rogers site it says only 850/1900/2100,

It doesn't work, at least out of the box, on the XL. It uses a different radio though so the international version could behave differently.

You have to be clear though. Out of the box, neither phone is going to get 3G data on an AWS carrier (T-Mobile, Wind). If you guys come up with a hack, people are going to have to root their phones and flash a new radio. A lot of people will be fine with it, some, especially novices, won't. And the hack for the G-Note gets the job done but you lose some signal and battery life in the process. Until it's running on someone's XL (and well) it's a little early to claim victory. I hope it works out for you guys.

T-Mobile AWS needs 1700 AND 2100 bands. It won't work with only one, so if you don't have both, you don't have T-Mobile 3G.
Not only that, if it comes down to simply being a radio flash you NEED S-OFF to flash a radio. An RUU won't work because there is no version of the X that supports T-Mobile frequencies.

I was today That by this summer in my area the iPhone will be able to get 3g and hopefully it's the bands we to make it work on the one x
Sent from T-Mobile's galaxy S II running ICS
(edit)
The iPhone has the same network bands as of the one x. Now we wait on TMO to update.

hopefully t-mobile gets this done by july. I'll be out of Army Basic training and will have money to spend on a International HTC One X beast lol... I currently have AT&T now. I was converted to a Radioshack AT&T employee plan a few months ago which changed my data plan from 2GB to Unlimited data which was freakin amazing even tho i only used between 1.5GB - 3GB of Data. Since i quit Radioshack bcuz im about to ship to boot camp, they gotta convert it back to a consumer plan (3GB data plan :-/) Idk what to do. If i come back from boot camp and ppl report that the AWS refarming rollout is actively in progress, im ditching AT&T and coming back to T-Mobile with a Tegra 3 One X. ( 6Mbits/sec is lightning fast enough for me to support playing Call of Duty on Xbox Live anyway. Ive done it on a T-Mobile Vibrant before.

[Q] Why AT&T has support for more LTE bands?

I was looking at the tech specs for the new HTC One and T-Mobile has less support for LTE bands.
Is it just a matter of HTC referring only to the bands that matter to each carrier or is it actually a question of different radios.
I ask because apparently the Google Play edition follows T-Mobile's hardware (possibly to provide support for both US GSM carriers), and makes it a no deal for international customers that need support to other bands.

In the review on Engadget they say there are 6 different versions of the phone. It seems the everyone who got it early for review received the international version without US LTE support. These are the radios for the AT&T and T-Mobile versions.
http://www.engadget.com/2014/03/25/htc-one-2014-review/
GSM/EDGE (850/900/1800/1900) (All)
HSPA+
AT&T: (850/1900/2100) with HSPA+ up to 21 Mbps
T-Mobile: (850/AWS/1900/2100) with HSPA+ up to 42 Mbps
LTE
AT&T: (700/850/AWS/1800/1900/2600)
T-Mobile: (700/AWS)
I've been looking into it myself because I'd like to get the T-Mobile version and flash the GPE rom and it does look like the GPE is the same hardware as T-Mobile's copy.
I really hate how these companies make a bunch of different hardware configurations. They're obviously capable of putting all the radios in one device, LG did it for AT&T, T-Mobile, and Sprint with the Nexus 5. N5 on T-Mobile is my current phone, I'm still trying to decide if the M8 is a worthy upgrade.

Yes the lack of compatibility between the two carriers is extremely annoying. I have the Dev Edition of M7 right now and it irks me to no end that I am stuck with AT&T with it. I'd totally buy the M8 if it supports all the frequencies of the AT&T version PLUS AWS for HSPA+.
I travel overseas a lot and I am very disappointed that I get more usage out of my old Samsung Galaxy S2 than the M7.

So how does this translate for M8 bought from somewhere else but used on T-Mobile network. I have ordered the M8 from Amazon (Prime shipping FTW), but it does not mention LTE bands.
http://www.amazon.com/HTC-One-M8-Unlocked-Warranty/dp/tech-data/B00J3554KE/ref=de_a_smtd
If I assume all non carrier branded M8 are the same, would the Play store description be accurate?
https://play.google.com/store/devices/details?id=htc_m8
Play store description mentions "700 MHz, AWS", which is a match with the engadget article "T-Mobile: (700/AWS)".
Would flashing a different radio software allow getting past incompatibilities, or the hardware itself is set to specific bands.
EDIT:
Just noticed this note at the bottom of Play Store page:
Compatible with AT&T and T-Mobile in the US. Check with your carrier for details about coverage.

From quick research, T-Mobile will get LTE in 1900MHZ by "end of 2014". I think I need to ask around a bit on Amazon/T-mobile and research some more...

Someone with more knowledge of radios can probably give a better answer than me but, as I said earlier, at first glance it looks like the Play Store (GPE) version has the same radios as the T-Mobile version. There's also a YouTube video of someone using a T-Mobile sim in their Verizon copy and it worked although, according to the data in the Engadget review, I don't think data speeds are as fast as they would be with the T-Mobile specific phone, at least on HSPA+.
http://www.engadget.com/2014/03/25/htc-one-2014-review/
GSM/EDGE (850/900/1800/1900) (All)

Verizon: (850/900/1900/2100) with HSPA+ up to 14.4 Mbps
T-Mobile: (850/AWS/1900/2100) with HSPA+ up to 42 Mbps
LTE
Verizon: (700/AWS/1800/2600)
T-Mobile: (700/AWS)
These are the radios in the GPE version
GSM/GPRS/EDGE quad-band 850/900/1800/1900 MHz
HSPA/UMTS quad-band 850/AWS/1900/2100 MHz
3G (850, 1900, 2100 MHz)

I just looked at the one Amazon is selling and it seems to me to be a Sprint version, although I don't know that the radios listed are actually correct since the Engadget article said all versions will support GSM/EDGE (850/900/1800/1900) and there's no mention of those on the Amazon product page. There's no mention of GSM or HSPA/HSPA+ at all so based on their data it wouldn't work with AT&T or T-Mobile.

Not sure, but maybe the data over there is not accurate? Even the Amazon M8 page for ATT version shows the same information.

This thread over on the M8 forum does not have much concrete info either:
http://forum.xda-developers.com/showthread.php?t=2694630
The radio situation is indeed a veritable mess. I wonder if there are any real tech/cost challenges which limit the radio compatibility or is it just the carriers being evil. I assume a standard hardware chip across all devices will be easier and cheaper to put in, so it must be the evil carriers forcing HTC then.
I am somewhat banking on the fact that unlocked phones (the one on Amazon) are most likely to be GSM compatible. Must get in touch with Amazon customer care I suppose rather than ranting here.

The Anandtech review actually shows that the GPe version combines the best of AT&T and T-Mobile!
http://www.anandtech.com/show/7893/the-htc-one-m8-review
It should work for both carriers.
It is instead missing WCDMA 900 so not optimal if you want to use it in Asia/Europe.

I did see somewhere that the DE has AT&T radios and the GPE has T-Mobile but that really doesn't make a lot of sense. I trust Anand so I think they're probably the most accurate.

No, T-mobile version will work for AT&T but not for Verizon.

What a ridiculous mess! Carriers shouldn't dictate what bands the phone comes in and they should all just be released in ONE model for GSM and all carriers get it.
I understand needing special models for Sprint and Verizon but for GSM its getting ridiculous.

Even the tmobile version doesn't show the 1700 frequency. Isn't that a requirement to be fully compatible with tmobile??

AWS = T-Mobile frequencies
AT&T, Unlock, and Dev versions will work on T-Mobile.
LTE = YES
HSPA+ = Depends if you area has LTE or HSPA converted from AWS to 1900
2G = YES
T-mobile version loses spectrum for LTE due to spectrum deals and HSPA+ spectrum support.
Qualcomm charges to license spectrum for their radio chips. Also it requires more hardware to support more frequencies. There has to be give and take, and would you pay $900 for the HTC One if it supported more frequencies?

Really? Apple has all the bands in one model. $350 Nexus 5 has all the necessary bands. So it is bull that it costs more, they just screw up every time. By the way I use the unlocked model and enjoying the M8 but no excuse for not having a single gsm model.

Sorry I firmly believe Google subsidizes a bit of the cost for their phones. They are using the console model to generate revenue.
Apple devices have a premium cost compared to majority of the items out there and doesn't include how much they make from iTunes.
The T-Mobile version is cheaper than the other GSM models.

Ok I will give you one more example...Sony unlocked devices in Sony store cost same as HTC One and they have all the necessary radios to work perfectly on r T-Mobile and AT&T. It's not that hard you know if you want to do a single gsm model.
And no Google is not subsidizing $500 or something, may be little bit they take a hit on profits from selling hardware but in no way they are fools to subsidize huge dollars. Like T-Mobile was selling Nexus 5 for $500 or something? Which might be the actual price.

[Q] Factory Unlocked vs T-Mobile Radios

Will the factory unlocked M8 support everything radio wise that the T-Mobile M8 will? I'm currently able to get one considerably cheaper than a T-Mobile one and just wanted to be sure.

I believe the unlocked is missing the 1700 band that hspa+ runs on. If you're in a reframed 1900 band area then you're okay. Otherwise you lose hspa+

Neither of the unlocked or Dev M8s will give you HSPA on AWS, so you’d have to be in an 850 MHz area. If you got the Dev edition, you’d be limited to 21 Mbps.
For LTE, the unlocked EMEA version won’t work at all and the Asia version will only work in areas where T-Mobile is transmitting on 700 MHz. The Dev edition will at least give you 700 and 1900 MHz, but I think T-Mobile currently has most of their LTE on AWS.

I've been around for several years now, but still very much uneducated about the radios and bands supported.
I have the GSM Dev edition. By reading the info in the last few posts about what bands/etc are supported and what speeds (HSPA, AWS, 4G, LTE) does this mean the Dev version is physically incapable of getting 100% service (edge, aws,...their whole network) on T-Mobile because of a lack of an actual component inside the phone? Or is it not "supported" because the firmware ( I.e....the radio software) is not included?
I guess my next logical question would be since I'm unlocked, s-off and superCID, would it be possible to turn my phone into a virtually identical T-Mobile phone? Or is T-Mobile's version of the M8 not even going to fully work on their network... Areas that haven't been refarmed yet.

This is what my post above was addressing.
The Dev edition is physically incapable of getting 100% service in all of T-Mobile's markets due to lack of hardware, yes. Therefore, it is impossible to turn it into an identical phone from the standpoint of radio compatibility.

The Verizon version is a little different than the T-Mobile version. The Verizon M8 is a little more limited with its 3G/HSPA since it only goes up to 14.4 Mbps vs. 42 Mbps with the two unlocked versions and the T-Mobile version. It has more LTE bands than the T-Mobile version, but at least one person on the Verizon board is having problems connecting to LTE on his Verizon M8 abroad.
Just in case you were referring to the Dev edition when you said “carrier unlocked,” those are different as well. I wouldn’t recommend using anything but the Verizon M8 on Verizon’s network since only the Verizon and Sprint models have CDMA radios and Sprint’s model doesn’t have the LTE radio to use Verizon’s LTE network (or vice-versa).

Are you able to connect to all T-Mobile bands? I want to pickup a used m8 but the T-Mobile variant is $100 more expensive than all the other carrier's versions. Does anyone know if I could pickup a used AT&T/Sprint/Verizon m8 and use it on T-Mobile without sacrificing frequency bands or anything?

Hi,
I know this is a really old thread, but I recently switched over from At&t to T-Mobile and similar questions about radios etc. Doing some internet searches I found Tom's Hardware review of the HTC One M8 (sorry don't have time to find the link), but according to the review the At&t and the US GPE version are the same version. Furthermore, both phones can fully support the AWS band for T-Mobile, however, At&t elected to lock the AWS band for the HSPA+ to refrain customers from unlocking and switching.
I was getting spotty service around my house, and just installed the T-Mobile radio and ROM on to my At&t M8. I will report on the performance once I have some time with the new set up.

How is this working for you? I have a vzw m8 and I'm over on T-Mobile, now mostly everything works,except for 4glte, it will work and then cut off after a bit, or if I travel between towers I loose connection and it won't try to find another tower, band or any other... So I get most out of this, just not all. And I was wondering which radio I used... Last time I tried a T-Mobile radio, I lost all connectivity. Btw I'm soff and supCID

Haha I know the pains of using a vzw device on gsm networks I had a LG g2 Verizon wireless and ran it on t-mobile I had to sell it had to reboot the radio about twice a week as well as take out SIM card

Helpful article
I found http://www.anandtech.com/show/7893/the-htc-one-m8-review very helpful to understanding the M8 radios.

Hey my phone is doing great! I even managed to pick up some better HSPA+ around the house - although I can't confirm if it is on the AWS band.
In terms of flashing the radio on the Verizon M8, I am highly doubtful that it will produce any valuable results. The CDMA version of HTC's always differs significantly from their GSM counterparts. If you look at the supported bands for the Verizon M8, there is no support for the T-Mobile UTMS AWS band - which is probably why you are dropping signal while switching towers.

Looking for a radio to get LTE band 2 on T-Mobile US

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).

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!

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.

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.

Which HSPA/UMTS band does the M9 unlocked US version support?

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.

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?

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.

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.
