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+.

I see some not so heartening details on Amazon/Play store. Updated my previous post. Will need a bit of research regarding the radio flashing as well as the LTE bands, but looks like T-Mobile and Amazon M8 may have trouble playing together.

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.
http://www.amazon.com/HTC-One-M8-Gunmetal-Grey/dp/B00IZ1VNZ2
This thread over on the M8 forum does not have much concrete info either:

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.
So to understand if I bought a tmobile version it work on at&t and verizons networks as well? I thought Verizon just had cdma phones not Gsm like tmobile and at&t

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??

The Amazon AT&T page updated to show following specs for network:

3G - WCDMA: Domestic 850/1900MHz with HSPA+ up to 21 Mbps; Roaming 2100 MHz -- 4G – LTE: 700/850/AWS/1900MHz; Roaming 1800/2600 MHz
Developer edition specs were also updated to show same specs.
http://smile.amazon.com/HTC-One-M8-Developer-Edition/dp/B00J3AYHOI/
The unlocked version (non developer shows Verizon like specs). Hope they are more accurate now.

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.

Has anyone bought either one? I just talked to Htc and it doesn't have those bands. Only 1700mhz

I believe the developer edition is essentially the AT&T version of the M8 just unbranded of course, the Google Play edition is missing one of AT&T's LTE bands I believe. I could be wrong.
http://www.anandtech.com/show/7893/the-htc-one-m8-review
Dev and standard unlocked are unbranded AT&T. Scroll down the page to see the chart. From wikipedia, 700mhz is band 17 so they should both be able to access LTE on 700mhz.
GPE has 1700mhz(AWS) for 3G while dev doesn't.
Is there a way to use Verizon HTC ONE with T-MOBILE with data speeds other than EDGE (E)? Is there any other methods like flashing a T-MOBILE radio (don't know even if that is possible). Would any MODS, developer or expert with insight to the hardware provides inputs ?
Thanks and Cheers!!!!
PS - I have seen other threads just cutting short to sell this phone and buy another one, I am trying to see if there is another solution
If I'm correct the reason why the device does not work on T-Mobiles LTE network is because T-Mobile runs there faster network on there 1700mhz band which is only supported on the T-Mobile variant of the HTC One. They have acquired some 700mhz spectrum from AT&T after there botched merger and have been using that spectrum to release some of the stress from the 1700mhz band. I have heard of it working on the the 700mhz spectrum but not the 1700.

If the hardware is compatible - would it be possible to flash T-MOBILE radio onto Verizon ONE?
The hardware is compatible its just that it does not have the compatible radio to work with their LTE/4G band to get data. It will get Edge no problem and the areas that are running on the 700mhz band but that's it.

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.

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

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.
Based on the research I've done so far, it seems like getting LTE on AT&T with an unlocked version of the N4 doesn't seem like an option. Is this right, that the international variants don't carry compatible frequencies for LTE in the US?
Do we have any options then for getting an un-carrier-branded version of this phone on LTE in the states?

The answer is no. The T-Mobile model "might" be the best option. Will know more when it is released.
What about AT&T's LTE band 5 (850)? I know it's limited in deployment, but if you live in the right area, the international versions do support band 5.
