Using the Unlocked AT&T Version One X on T-Mobile? - HTC One X

If I were to buy an unlocked AT&T One X to use on T-Mobile, would I be able to pick up T-Mobile's LTE after they roll it out in 2013?
Is the only difference between the AT&T version of the phone and the international version that the AT&T version only has a dual core chip but has LTE?
Edit: Also, what is the theoretical max speed of the HSPA+ of the chip on the AT&T phone? Is it the 42Mbps? (I live in a T-Mobile 42mbps market, so once they refarm to 1900MHz I'm wondering what I'll get at that time, before T-Mobile rolls out LTE)

It's a completely different processor, they are basically completely different phones that look similar.
You should ask your questions in the correct sub forum, as thus one is for the Tegra3

[Q] Does the quad-core HTC One X support AWS bands?

Hi, I'm seeing conflicting information on whether the quad-core (international) HTC One X supports T-Mobile US's AWS bands. Engadget and other sites are reporting that it does. But HTC's own specs don't mention it.
Does anyone have any light to shed on this?
Thanks, Alan
Yes, HTC One X will support Tmobile's AWS band
Hi, as we do know the T-Mobile HTC One X will debut in early April, for a yet to be released date, though T-Mobile didn't provide exact release date. As you mentioned that HTC' site doesn't give any clue whether it will support AWS band or not. We can say that it will be updated soon for sure, as well as T-Mobile reveals a release date. We suspect that HTC didn't show T-Mobile AWS band as the device is only available for pre-order from various retailers, so it will update it soon as well as T-Mobile reports.
I'd really like to know the answer to this question also. To add to the confusion, HTC's site for the AT&T version of the One X (Called the One XL) does show that it will support AWS: www.htc.com/us/products/htconex-att#tech-specs
It doesn't make a lot of sense to me why the AT&T specific version would support AWS for T-Mobile (never seen that before in an AT&T specific phone). In the past it was usually the international version that supported AWS. I don't see any of the various phone/gadget blogs mentioning this about the AT&T version either.

I don't understand what you're talking about here. There's no T-Mobile HTC One X. T-Mobile is getting the One S (the lesser midrange handset). That's what was announced at MWC this week, to appear in the spring.
For what it's worth, here's a rumor that T-Mobile will get the HTC One X in the summer (with the Tegra 3 quad-core cpu and stock Android even).
www.androidandme.com/2012/02/smartp...e-to-get-stock-android-4-0-and-quad-core-cpu/
I'm wondering myself does Tegra 3 Quad core support AWS band and if so does it support HSPA +42 or HSPA +21? Also is it the One X Terga coming to Tmobile Usa or One XL Snapdragron coming to Tmobile USA? Like another poster said the HTC website shows the AWS band for One XL under AT&T but no AWS band for One X under international version.

Come to think about it somebody posted the build prop file for the HTC Endeavor aka HTC One X and it did not list compatibility with AWS band.

This is a bit of speculation on my part, but it could be that AT&T ordered the HTC One X to be compatible with T-Mobile's AWS since they predicted that the merge was going to go through. Lets not forget that AT&T and T-Mobile do have new roaming agreements after the merger fell through.

That makes a lot of sense. Seems plausible.
Don't know if it means anything, but GSMArena now lists the AT&T One X as having AWS (I assume they probably just pulled it from the HTC site and I do find that GSMArena's stats can be a little unreliable):
www.gsmarena.com/htc_one_x_at&t-4614.php
I'd hate to have to have an AT&T branded phone to get AWS though. I like the unbranded phones.

Hmm. There's also this story, from yesterday (and spreading rapidly), that quad-core variant of the One X has cleared the FCC, headed to an unknown carrier:
www.pocketnow.com/android/quad-core-htc-one-x-gets-fcc-certified
And this rumor from a week ago that T-Mobile will get a stock Android version of the One X:
www.androidandme.com/2012/02/smartp...e-to-get-stock-android-4-0-and-quad-core-cpu/
From what I read this morning, international version of the One X will be with AT&T. Therefore, the chance of One X being available on T-Mobile dropped, but its not for sure until CTIA in May. Hopefully they'll announce something.
Other than that, T-Mobile customer may be able to use international version of the One X on T-Mobile someday. Since T-Mobile may or may not be refarming their 1900 GSM spectrum. If they do refarm it to 1900 UMTS, then I'll be one happy T-Mobile customer.

Where are you getting this? It's well known the AT&T is not getting the international version, but rather a different version with a Qualcomm dual-core processor, to accomodate AT&T's LTE network. Even HTC's own website list's a separate AT&T version of the One X, from the international version.
Also, if you look earlier in this thread, the AT&T version in the specs on HTC's website support's T-Mobile's AWS frequencies. So there may be more than one avenue to get a One X that works on T-Mobile.

First, I've worded it wrong regarding the international version. I meant to say that the international version is compatible with AT&T. Won't be offered on AT&T, but the UMTS bands has 1900/2100 on it so it could be used on AT&T.
HTC One X
I think I might have missed the AWS spectrums for the XL. Personally I don't think I would put too much hope into it, because the XL for AT&T is meant to focus on LTE. If you look on the T-Mobile Reinvigorated Challenger Strategy Presentation, AT&T's AWS also ties into their LTE.
T-Mobile's refarming their GSM 1900mhz, hopefully to UMTS 1900mhz. If that's the case, T-Mobile users will still have a chance to use One X or One XL on T-Mobile.
T-Mobile USA Reinvigorated Challenger Strategy Presentation
There's also rumors that One X will be coming to Sprint and to T-Mobile as the G4X. The time the possibility of announcement is probably in May.
Rumor
So I'm trying to hold out till May to see if I could see an announcement. If not, I think I might be getting the international version of One X, then wait patiently and hoping T-Mobile will hurry up and refarm the 1900 spectrum. There's also words that the refarming has already been going on, with more iPhone users noticing that they could get 3G speed.
Thanks for the further explanation and links. I could be wrong, but it still seems to me like the AT&T One XL might work on T-Mobile. If you look at the specs on HTC's website, you can see that it has AWS not just for LTE, but also for WCDMA (i.e. UMTS).
www.htc.com/us/products/htconex-att#tech-specs
I don't see why that wouldn't work with T-Mobile. As nickmgray points out above, it's plausible that AT&T specified the bands for the One XL, before they knew that the T-Mobile merger was going to fall through. Hence at the time, they may have wanted a phone that would work with T-Mobile's network.

I'm not holding my breath on the spectrum refarming being a solution for the One X. Unfortunately I can't remember where I first read about it, but my understanding is that it will take a couple years. At that point there will certainly be more compelling phones than the One X.
Also, if you look at the charts in the link you provide to the T-Mobile Strategy Presentation, you can see that even after the refarming, it appears T-Mobile will still be using AWS for HSPA+, as well as for LTE. So it seems that a phone that does not have the AWS bands could suffer significant coverage issues. T-Mobile's goal in the document seems to be to make the network better for in-bound international roaming and more compatible with devices from other carriers. But a phone without AWS for a U.S. resident would still be limited.
It would be nice though if international and AT&T phones were fully compatible with T-Mobile's network. That would give T-Mobile a nice advantage with handset options; and a good way to tempt away AT&T customers (who could then keep the phones they already have). But, again, it seems like this is something for the future and not a way to count on using the One X with T-Mobile.
I'm hoping HTC will just make an international version with the AWS bands, as is the case with the Sensation. Or it would be great if they put a pentaband radio in the international version, like Nokia has been doing for a while. Or maybe the Tegra-3 One X for T-Mobile rumor will turn out to be true.
I actually like the size of the One S better. But it's not worth it to me without the 720p resolution and 16 Gb of memory (without a microsd expansion slot).
Just looked at the FCC's documents on AT&T's One X.
The document doesn't mention testing any of T-Mobile's bands. Don't know if they didn't test it, or the phone don't have it.

Thanks for the link. I'm not sure what to make of that. For example, they only list GSM 850 and 1900 frequencies. It would be really unusual for a phone these days like this not to be quad-band GSM. So it seems like the FCC report is probably not listing all the bands the phone can operate on, only those that it will use with the AT&T network. I'm not sure this really answers the question about AWS in the AT&T One XL.
What about the One X with the tegra-3 processor that went through the FCC? Do you know where the report for that is? I can't really see how to search the FCC website.

Thanks for the link. Again, this doesn't really indicate that T-Mobile is completely refarming HSPA+ to 1900 Mhz. It just says, "A nice side benefit of the refarming effort is that our 4G network will be compatible with a broader range of devices, including the iPhone." The fact that more different devices will technically work on the network, does not mean that they will get the same coverage as devices that work on both 1900 Mhz and AWS. As the other document you linked to indicates, after the refarming HSPA+ will be on both 1900 Mhz and AWS, so it may mean that if you want the best coverage on T-Mobile's network, you need a phone covering both frequencies. Time will tell I guess, but it doesn't seem clear yet.
And, as I said, this is so far down the road to completion (they're starting now, but it will take a couple years to complete) that I don't see it as being a good solution for using a One X that lacks the AWS bands on the T-Mobile network.
Took a while, but I found the international version of the One X on FCC.
One X FCC
Looking at the model number and matching with other site, it looks like it's the one. The only problem is, it doesn't show any frequency testings. I also looked up the One S and found 3 model numbers, seems like only the one coming to US is the one with the frequency testings.

[Q] Can the HTC One X be used with T-Mobile?

Hi, I was just wondering if the HTC One X (Unlocked) be used with T-Mobile, because I'm currently using a Samsung Galaxy S2 (Hercules) and the lack of ICS is pi**ing me off, I miss my HTC Sensation in which I had ICS months ago; I don't think T-mobile is planning on releasing ICS for the SGS2 somewhere near the future.
For now I'm stuck between Samsung Galaxy Nexus, Galaxy Note and The HTC One X but I don't know if either of the will work on T-Mobile . Can someone please let me know. Sorry for my english.

Puerto Rico I travel a lot to the states as I work for U.S Deparment of Defense.
This is a very good question. Tmobile claims to use 1700/2100 band for 3g/4g
The specs for the ONE X are : WCDMA/HSPA 850/900/1900//2100 MHz
And GPRS/EDGE/GSM 850/900/1800/1900 MHz
From this information I am unsure whether it will be fully compatible. These numbers look more like an ATT phone than tmobile. Im assuming it will work with edge but 4g is most likely not going to happen. I ordered a one x and intend on using it with t-mobile, so it would definately be beneficial if someone was confident it would work on tmobiles network. Hopefully someone will have one and test it on tmobiles network before I get mine in the mail.

420kushking is correct regarding the spectrums.
However, there are reports that T-Mo iPhone users were able to use 3G on T-Mo network. I've also checked T-Mo spectrums, PCS 1900 mhz 3G spectrums are available on T-Mo on areas in the US. If you're planning to use T-Mo and plan to get the phone, you should probably call T-Mo to see if 1900 mhz is available in the areas you'll be going to most often and make sure that you'll be able to get 3G coverage on your phone. If you ask if the phone will work on T-Mo, the customer service will probably say something like the phone will work on T-Mo but they can't guarantee if the 3G will work on the phone. So it's better to ask of the spectrum is available instead, that might be a safer bet. Even tho the spectrum may be available, but that probably doesn't mean that the 3G will definitely work. These are just some information for you to consider.
I'm also planning to get a One X to use on T-Mo, and hopefully what they say about the 1900 mhz spectrums are true. I couldn't test the 1900 mhz spectrum on my Desire HD because of the 900/2100 bands on the phone.

Well yeah it will work but will it be able to utilize the 4g network I think is the question here. I have already pre-ordered the one X unlocked version and I do have tmobile. I will be doing extensive data speed tests when I get the One X, but I do not expect anything better than an EDGE connection on T-mobiles network.
To me this is a big deal because if the One X does not work with 4g on tmobile, It also wont work with 4g on ATT because its the Tegra 3 version, and if you have been looking at specs the tegra 3 unlocked version does NOT support LTE... If I dont get the speeds I need then it will end up on eBay.

The one x will get 4G speeds on att. "4G" as in HSPA+ not LTE. So you'll get decent speeds, just not LTE speeds. I Wouldn't bet that the one x will work on tmobiles 3G networks let alone their 4G networks. Edge seems about right.
Thanks to you all for answering my question, I was about to pre-order it on when I read that it was "Sim-free", what does that mean, does that mean it has no sim card slot. Im kinda confused here.
Never mind after a bit or reading I've learned that sim-free means it comes with ail, but it does has sim card slot.

SIM-Free means you can use whatever network uses GSM
I don't think the One X will support Tmobile AWS band. The only hope for this phone to work on Tmobile 3G/4G is if Tmobile has switched 3G/4G over to the 1900 band in your area.

Realistically? No, since it doesn't support the AWS Band (1700 AND 2100).
However, if you live in an area when TMo has deployed the 1900 band, it will work. If you live in that area, that is.
Also, "sim-free" means it comes straight from the manufacturer, without a carrier's SIM card.

Nope 1700mhz/2100mhz in here... Sad but true
I was looking for the specs at gsmarena and I found that the at&t versions supports the following bands:
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 850 / 1700 / 1900 / 2100
4G Network
LTE 700 MHz Class 17 / 1700 / 2100
I'm not too familiar with this subject but I believe that T-Mobile uses 1700/2100mhz, does this means the At&t is a true candidate for T-Mobile Compatibility?

I think the version of the phone you would be referring to is the one X att version, It has a dual core qualcomm s4 krait instead of the tegra 3 processor. There is some debate over the performance of the krait vs the tegra 3. I know from a benchmark video that the tegra 3 outperformed the transformer prime. I think the krait outperformed the tegra 3 though by a bit. I ordered the unlocked one x that has the tegra 3 so it doesnt support tmobile 4g or att 4g based off the specs. When I get it I will test on both networks. My concern is that since I ordered the tegra 3 version, it wont be supported by ATT 4g OR t-mobile 4g. We will see I guess.

Ok good to know. Does anyone have information about speed tests on their regular 4g network? Is the LTE that much faster to where it would be worth it to invest in an LTE based less storage model? I have both att and T-mobile but I think the 4g on t-mobile is faster based off my speed tests. I do NOT have an LTE device to test the differences. I am in Los Angeles/ Orange county area.
I'm considering switching to T-Mobile with an unlocked One X, and appreciate the info in this thread. One question: some are saying it will work with HSPA+ on ATT. Will the phone roam to ATT if it sees an EDGE network in range, or will I be stuck with the lower speed? Oh, and does TMob charge for data roaming to ATT HSPA+?

For those one on T-Mobile/wind Mobile/Mobilicity users...

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:

LTE:

•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

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"
Link to AT&T's site:
http://www.wireless.att.com/cell-phone-service/cell-phone-details/?q_sku=sku5980268#fbid=n77DzSAk3I2
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...

Take the example of Lumia 710
It is a pentaband phone (850/900/1700/1900/2100) but on Rogers site it says only 850/1900/2100,
But after unlock, this phone works on Wind Mobile (same as 3G T-Mobile)
So hope to get this phone on hand ASAP, so I can try...

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

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.

What does this mean...?

when I go through the specs for the AT&T and Tmobile variants for the note 2, I come across a difference in the following
AT&T,
GSM Quad-band: 850/900/1800/1900 MHz
Tmobile
Frequencies and Data Type GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
What does the dual band mean? Is it for Tmobiles 4G network?
I thought all the Note 2's in the US had the same LTE radio
please shed some light,
thanks
1700 MHz/2100 MHz UMTS (WCDMA) AWS is currently T-Mobile's 4G network.
T-Mobile will have LTE up and running sometime within next year (2013).
Yes T-Mobile Galaxy Note 2 devices do have LTE. But it is now not activated. T-Mobile will activate the LTE within T-Mobile's Galaxy Note 2 when they get their LTE service up and running within your area.
How to activate the LTE and running on another carrier is a good question. This I get bits and pieces. But not a full step-by-step process yet.
The T-Mobile Note II is pentaband; it will work on AT&T and T-Mobile 3G/4G (not LTE though as of now). I think that's what you're getting at.

I believe that we can get the LTE up and running with other carriers. I know that I got LTE working on my GN2 (SGH-T889). We just need to learn how to get the LTE running with other carriers. That is really the question. When we figure that out then this might be able to be applied to other GN2 devices.
Tmobile hasnt turned on lte yet. From what i understand once they do our note 2's should be able to utilize it.

Tmobile uses 42.2 mbps dual channel hsdpa.
Afaik, At&t uses 21.1 mbps hsdpa.
Lte(long term evolution) is a different technology not yet active for Tmobile customers.
Real World, my friend with a Galaxy nexus on Tmobile network gets about 8mbps while I get 14mbps. Galaxy nexus has the 21.1mbps capable modem.

You're talking about something called DC-HSPA (Dual Channel/Carrier), which is basically what you said: Using 2 frequencies of HSPA(+) to achieve basically double the throughput.
Is it a hardware limitation (as in slightly modified Qualcomm LTE Chipset) in the AT&T Note 2 that 42mbps is not supported compared to T-Mobiles version? Or it is software / firmware-controlled?

It could be software (on the modem level, which is low-level stuff and separate from the ROM); T-Mobile's Galaxy S II was basically AT&T's Skyrocket with LTE disabled. You could actually flash a T-Mobile S2's modem onto a Skyrocket to get it to work on T-Mobile frequencies (but you can't get LTE enabled on the T-Mobile S II as far as I know).
would you say the note 2 from verizon is any better since it also includes a CDMA radio? Also, though LTE only works in the upper 700 frequency, any change a modem update or firmware change will allow the verizon version to work on T-mobile or AT&T network?

No; CDMA is useless unless you're going to be using it on the carrier it came from. I'd say the T-Mobile version is the best (in terms of working with the most networks), then the AT&T version (because it has LTE), then the International version (because it's the AT&T version without LTE), and after that the Verizon one because Sprint are jerks because they use "embedded SIMs".

[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+.

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

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.

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.

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.
