Yeah... I was thinking the same thing. I called HTC and spoke to someone in customer service who confirmed it... Although she didn't sound very convincing. Still, I think there must be some truth to it since the GPE is listing the same specs.

Hi I represent the HTCdev team. HTC One M8 Developer Edition does not support Verizon networks. It does support AT&T and T-Mobile LTE.
[One (M8) Q&A, Help & Troubleshooting] motoridersd:
What about T-Mobile's Band 12 LTE and their HSPA in AWS. Is it also HSDPA 21 or 42 Mbps?
[One (M8) Q&A, Help & Troubleshooting] jad:
Yes the software includes the FM radio app.
[One (M8) Q&A, Help & Troubleshooting] thekalby:
Why would anyone get the Google Play Edition for $50 more than the Dev? If you wanted the silver one, you could just buy the unlocked version. Its the same as the dev pretty much.

Wont we just be able to flash the Google Play Edition roms on the other models? Or do the different radios break compatibility with the ATT version?

Maybe I am slow - T-Mob Q

Maybe we have confirmed this already, but I am still not sure. Does any expert on here have confirmed info on band support:

Which is a better phone Dev Edition or GPe for T-mobile LTE?

If not fully compatible, what can we expect will not work on either?

I have both on order and I cannot figure out which to cancel.

Also, it appears the Verizon version does support at least some t-Mobile bands. Can someone post the T-mobile bands and explicitly define which is compatible with T-mob LTE and which is not?

Thank you in advance

AC
[One (M8) Q&A, Help & Troubleshooting] motoridersd:
The Verizon one will be compatible with T-Mobile LTE band 4 (AWS) because Verizon uses that band for LTE too. That is the only one that overlaps.

On the GSM side, the Verizon model supports 1900 Mhz WCDMA which would give you HSPA+ in T-Mobile LTE areas but limited to 14.4 Mbps. It would be like having an even slower version of the ATT model.

It's been a long time since I've owned an HTC. Back then they didn't have HTCdev. Out of curiosity - is it possible to unlock the bootloader on a carrier version (i.e. Verizon) using the HTCdev unlocker?
[One (M8) Q&A, Help & Troubleshooting] kirdroid:
Not possible.
[One (M8) Q&A, Help & Troubleshooting] jtc276:
It depends. Sometimes the carrier locks this feature. Sometimes they don't. For instance, AT&T didn't lock it on the M7. I'm not sure about Verizon, though.
[One (M8) Q&A, Help & Troubleshooting] itsxiao:
DE and Unlocked are both back up on htc.com but are backordered 1-2 weeks. Info on the website is severely lacking and there are errors in the listings.

From ZDnet review which I found helpful since I am T-mobile:

The HTC One M8 will be priced at $199 and $249 with a two-year contract, depending on the carrier. T-Mobile will eventually have it available beginning on April 11 for $0 down with the full price of $636 paid interest-free over a two-year period. The T-Mobile version will also support WiFi Calling, which is a great utility for those who are traveling or have a weak signal at home.

There will be a Google Play Edition that works with AT&T and T-Mobile in the US, available for $699. It will be up for pre-order on the Google Play Store and available in silver. I could order a Google Play Edition device, but I think an HTC One without Sense isn't worth the price, due in large part to the camera technology.

A Developer Edition is also going to be available on HTC.Com as a SIM unlocked model for $649. It's based on the AT&T SKU, so there are limits for T-Mobile customers."

So basically the DE or unlocked versions will lack the HSPA+ band which is huge for tmobile. So unless you get good LTE service in your area, this could be killer if you're a tombile customer. I myself don't want to pay the extra $50 for GPe since I want to try Sense 6 and pure Android seems a bit boring for me.
[One (M8) Q&A, Help & Troubleshooting] Richard Rahl:
Q1. The T-Mob carrier M8 version will be unlocked, right? Which means, basically what? I'm a newbie to these things. I have an HTC ONE(s) from what 2-3yrs back...I like it...now I wish to upgrade so I'm deciding which M8 "version" to get.

Q2. If I get the GPe version, (I am on T-mobile like you)...will I still have wi-fi calling available, or is this something that someone could show me how to add?

Q3. In order for the sense 6.0 to be put on top of the GPe, is that easy? The reason why I hesitate to get the T-Mob version of the phone, is all the effing bloatware they add on which I detest. I hate the visual-voice mail crap and all the other apps that ALWAYS need updating every 2 bloody weeks that I never ever ever effing use!

Thank you for the reply above, it informed me quite a bit...and hoping you or someone else can make my decision simpler.
[One (M8) Q&A, Help & Troubleshooting] itsxiao:
Unlocked means that you can pop in a sim card from any GSM carrier and use it. So an unlocked version can be used across T-mobile or ATT. Wifi calling I've never personally used since I have signal at home. I also can't think of many places that have wifi but not signal (other than international). But then again, many apps currently offer things similar to that such as WeChat which sends Voice Messages. I do not believe the GPE will have wifi calling. In fact, it won't have any of the stuff HTC has added which includes camera software and some of the movement and touch based commands. However, GPE will receive updates faster than carrier based variants, but some people don't like plain Android while others want the most streamlined possible.

Sense isn't to be put on top of GPE, it's equal to Touchwiz of Samsung, and I believe has to be flashed like a rom and not just installed like an app.

That is the dilemma that you and I are faced with right now. Do you want to wait and get the T-mobile version which covers all the bands we use but at the cost of maybe T-mobile loaded crap? OR would you rather get the DE/Unlocked versions that are ATT based and lack HSPA+ speeds which leave you with either 2G or LTE(if you're lucky). OR pay extra for the GPE that doesn't have Sense 6 or HTC proprietary camera software (all this can be flashed later once a ROM is created).
[One (M8) Q&A, Help & Troubleshooting] SolarTrans:
Answers:

1: I do not believe any specifics have been revealed about the T-Mobile model yet, but if it is unlocked that will mean the device will function with any SIM card (to some extent at least, depending on if it supports the frequencies of the carrier who's SIM you put in). However, it will be 100% compatible with T-Mobile. From the info that we have, the generic unlocked and Developer editions are all based off of the AT&T SKU of the device (meaning that the only US carrier they fully support is AT&T. T-Mobile SIMs will function, but without the AWS band it will be to a very short extent. You most likely will get very limited coverage). The GPE is based off of the AT&T SKU, but it has the AWS band active for sufficiently better carrier support. With the GPE, you'll have full T-Mobile and AT&T functionality.

2: I believe that WiFi calling is only available on T-Mobile specific carrier devices, so the GPE would not support this. ONLY the T-Mobile version would.

3: On the carrier version, you can go into settings and DISABLE all the bloatware apps from your carrier (this is what I did for my AT&T branded GS4). They won't uninstall (so they'll still be physically there on your flash storage), but they'll not show up on your phone anywhere and you won't ever be prompted for updates.

It is relatively simple for Sense 6.0 to be put on the GPE. Although you can essentially add Sense 6 through the Play Store, I believe you'll lack deeply-integrated features like the tap-to-turn on and all of the motion controls (were some of the phone's best features IMO, as the lock button is quite hard to reach). However, they made the GPE fully compatible with the dual cameras straight out of the factory, and all of the Sense apps (like the Blinkfeed launcher) will be available from the Play Store. I would warn you, though, that this year the GPEs will most likely suffer from the worse-camera fate that they did last year. Although all of the capability is there for the dual cameras, they'll most likely perform much worse than their HTC skinned counterparts.

Advice: If you're going to be buying off-contract, it is a really tough call. The GPE is a couple weeks out, but so is the T-Mobile version. I'd opt for a 32GB model from T-Mobile and just disable the bloatware, because I really can't see myself using one of these without the ability to use the gesture unlocking. But who knows, if more information is revealed and it turns out the Developer edition has the AWS band, then by all means pick up one of those.
[One (M8) Q&A, Help & Troubleshooting] mkhopper:
I'm a total GSM n00b as well and I'm flipping from Sprint to TM with the purchase of the M8. If I'm reading everything correctly so far; in terms of a TM user, if I want to have the best possible high speed, I'm better off waiting a few more weeks for the TM branded version to be sold rather than picking up either the GPE or Dev version now, correct?

Of course the drawback to this would be dealing with whatever extras TM decides to bundle in for awhile, but I'm sure that once decent roms start rolling out, all that junk would be wiped out anyway.
[One (M8) Q&A, Help & Troubleshooting] itsxiao:
As far as I've read and understood, that is correct. Since we rom a lot anyway, I could deal with some of the bloatware for a bit until ROMs start rolling out. I wouldn't say highest speed, it's more or less a wider spectrum of speeds that the phone will be able to pick up. So if you live in an area where Tmobile hasn't deployed LTE yet, a DE or Unlocked version won't be able to fall back on the 1700 HSPA+ band. I think I'd rather wait a couple of weeks to see what the Tmobile version is actually like first before I pull the trigger since it's such a big investment. I also would rather have a wider range of use than hope I get LTE. I think it's ridiculous GPE is $699 when there's less features..
[One (M8) Q&A, Help & Troubleshooting] SolarTrans:
Not sure if you caught my lengthily response earlier, but I'd wait.
[One (M8) Q&A, Help & Troubleshooting] krabman:
I went DE. I'm not seeing much reason for GPE with this phone unless you need the radios since you can go to that software soon enough anyways if you're of a mind. I do travel a great deal but I already have an N5 and an SGS4 and I can use those if I'm going to a place that isn't in this phones repertoire. Also I haven't had sense for a few iterations so I figure I may as well give it a spin. Realistically it only has to last till the N6 comes out anyways... I'm such a slut *facepalm* :)
[One (M8) Q&A, Help & Troubleshooting] djkinetic:
It's confirmed that the ATT version unlocks via HTC Dev and also can flash/run WWE based international variant Roms. The only carrier so far it seems that is locked down is Verizon which isn't surprising since the M7 was blocked on HTC Dev for Verizon as well.

As for the bloatware, there HAS to be a way you can delete all of what I Don't want, instead of just blocking it, right? It doesn't make sence otherwise.
[One (M8) Q&A, Help & Troubleshooting] SolarTrans:
It doesn't make sense, but there's no way to delete it without rooting :P. There probably is if you root, but I haven't looked into that because I've never had carrier Android devices (that have been on stock ROMs anyways).
[One (M8) Q&A, Help & Troubleshooting] xavier2k3:
Can anyone confirm that the Developer Edition/Unlocked Version's band frequencies have been changed this year from last year's M7 which was 850/900/1800/1900/.

Android Central Claims

But the HTC Official Site states:

This would make the LTE bands 700/850/1700/1900.

I want this phone to be able to use both in North America/Canada as well as my home network in the UK who use 1800/2600 for 4G.

[One (M8) Q&A, Help & Troubleshooting] aaronc_98:
Sorry Guys- I am still not confident about T-mo

Here is the info that I got from wikipedia for T-Mobiles network:

Frequency Band	Band# Radio Interface

1700/2100 MHz AWS	4	LTE

700 MHz Block A	12	LTE

1900 MHz PCS	2	LTE

900 MHz PCS	2	UMTS/HSPA+ 21Mbit/s

1700/2100 MHz AWS	4	UMTS/DC-HSPA 42Mbit/s

1900 MHz	2	GSM/GPRS/EDGE

850 MHz CLR	5	UMTS/HSPA+

850 MHz	5	GSM/GPRS/EDGE

Here is what I got from HTC on the DE:

This special HTC One® Developer Edition comes with: 32GB of onboard memory, SIM unlocked and has an unlocked bootloader.

Compatible on these frequencies:LTE Quad Band (Bands 17/4/2/5); LTE MIMO;

GSM/EDGE: Quad-band (850/900/1800/1900 Hz),

Class 12; UMTS: Tri-band (UMTS 850/1900/2100MHz),

HSPA+ Category 14xx (HSDPA 21Mbps/ EDCH 5.7 Mbps);

Here is what I got from Google Play on the GPe:

Unlocked GSM/UMTS/HSPA+/LTE

GSM/GPRS/EDGE quad-band 850/900/1800/1900 MHz

HSPA/UMTS quad-band 850/AWS/1900/2100 MHz

3G (850, 1900, 2100 MHz)

HSDPA 21, HSUPA 5.76

4G LTE (700 MHz, AWS)

It appears to me that the GPe will be more compatible with T-Mobile- is that a correct statement? Though I am not clear on the LTE for the DE because of the way they describe it.

Can one of the frequency experts please tell me the deficiencies for either device on T-Mobile?

thanks,
[One (M8) Q&A, Help & Troubleshooting] mikemol:
No, they are pretty much the same as far as T-Mobile compatibility.

This is what T-Mobile network uses for 3G connectivity:

1700/2100 MHz AWS	4	UMTS/DC-HSPA 42Mbit/s

This is what DE has from your post:

UMTS: Tri-band (UMTS 850/1900/2100MHz),

This is what GPe has from your post:

3G (850, 1900, 2100 MHz)

So the DE and GPe both are only tri-band in 3G - they both have 850, 1900, 2100 and both are missing the 1700 that we need. Both of the DE and GPe will not work on 3G at t-mobile. They will only work on Edge everywhere or might work on 4G where there is 4G coverage but not on 3G.

I'm on Wind Mobile in Canada that uses the same bands for 3G as T-mobile and we don't have a 4G on Wind Mobile so I'm waiting for T-Mobile version to come out to buy it to use on Wind Mobile. Mobilicity clients are in the same boat.

[One (M8) Q&A, Help & Troubleshooting] aaronc_98:
So you have yo have all the bands for it to work? It not good enough that they only have 1900 for 3g?
[One (M8) Q&A, Help & Troubleshooting] mikemol:
TMO doesn't use 1900 in 3G. It needs 1700 and 2100. From what I heard it sends on one and receives on another so it does need to have both. That's why just having 2100 won't work. Too bad HTC didn't put out full AWS phone as their developer edition phone. Lots more people would have jumped on it.
[One (M8) Q&A, Help & Troubleshooting] krabman:
Depending on what freq they are using in a given area you will either have coverage or you will not because they don't use both freqs in all areas, this is why you want both unless you know your home area is on 2100 and you're not worried about coverage elsewhere where it might only be 1700 leaving you out in the cold in that area.

Can someone explain this to me? Everyone is talking about the "3G (850, 1900, 2100 MHz)" line from the GPE specs with regards to T-Mobile data speeds (as a T-Mobile user I'm very interested in this). But doesn't the "HSPA/UMTS quad-band ..." line also refer to "3G"? (Or 3.5G depending on your nomenclature?) Doesn't the AWS on that line contribute to T-Mobile compatibility? Or am I getting my mobile technologies confused?

[One (M8) Q&A, Help & Troubleshooting] SolarTrans:
Considering Google explicitly mentions the GPE will be compatible with T-Mobile, it should be fully compatible. Right? And T-Mobile usually uses 3.5g (HSPA+) and has relatively few towers for all other types of internet (IIRC). So wouldn't it be OK? I looked at the specs page for the T-Mobile GS4, and it says it supports

UMTS: Band I (2100);UMTS/HSPA+: AWS Band IV / 2100 / 1900 / 850;Band II (1900);Quad Band GSM;LTE.

This doesn't look all too different from what's on the specs pages we've seen, and the T-Mobile S4 fully supports LTE.

Sounds like you are getting LTE in your area as the N5 does not support either 1700 or 2100 but does support both 4 and 17 NA LTE which are the same freqs as supported by the tmo variant. Realistically either the GPE or else the Tmo iteration are going to be the one you want although you would be good with any of them in your home area as far as data since you have LTE.
