I have a m8 asia version.
rooted, unlocked with a custom rom.
This is my phone spec with the supported freqs:
https://goo.gl/HLiiF2
Am I able to use at&t's 4G LTE service?
If not, what's the max I got with this phone?
If it's below a H+ I might consider buying a new one..
Thanks for the help!
I don't think the link you posted is specific to the Asia M8 (does not list the proper LTE bands for the Asia version - and band support varied by version). It lists the LTE bands for the EMEA version. I think the following has the proper bands for the Asia version: http://www.gsmarena.com/htc_one_(m8)-6074.php
In either case, the bands listed (either on your link, or the one I posted) do not include any of the LTE bands used by AT&T. AT&T uses LTE bands 2(1900), 4(1700/2100), 5(850), and 17(700)
Support of all the bands (2, 4, 5 and 17) is needed to ensure LTE service in all regions serviced by AT&T (what band they use, varied by locality). So just missing one of the bands can be a problem. And your phone doesn't support any of the bands used by AT&T!
It very unusual for phone versions intended for other (foreign) regions to support all the AT&T bands. So when purchasing a new phone, its best to look at models intended for use on AT&T.
Note, that with s-off ($25 by sunshine is the only way) you can flash the AT&T baseband radio, which in theory changes the band support. However, its still not guaranteed that you will still get LTE on AT&T's network with an M8 "converted" in such a way. We've seen reports of folks getting s-off, and flashing the "proper" radio, only to fail getting LTE on their local carrier. I haven't seen a satisfactory explanation of this, or a fix, unfortunately.
So its an endeavor which costs money, and may ultimately not work. So if you have the option to do so, I would recommend to return the phone, and get another model that supports AT&T's bands out of the box (for the M8, that would be an AT&T branded version, or US Developer's Edition).

I recently won a m8 in a contest. And through lots of searching I'm stuck, I live in the UK and my phone is from the US. I want to know if my phone has the right hardware to get lte on bands 3 and 7 as I'm on ee. But I cannot find out anywhere what hardware is inside the device, any suggestions? Thanks.
Check the preferred network (in settings) if you can enable lte connectivity.

Hi!! a have the HTC One® Developer Edition (M8) and this supports the followings Bands in LTE: LTE Quad Band (Bands 17/4/2/5).
Check the exact model of your M8, with this tool: https://play.google.com/store/apps/details?id=org.tritonsoft.cidgetter&hl=es-419
Cid code is needed to find your exact model and get the description of networks supporting.

Any carrier branding (Verizon, Sprint, AT&T, T-Mobile) on the outside of the phone or on the OS (splash screen, etc.)? Mosts US M8s are branded, aside from Dev Edition, unlocked, or GPE.
As long as its a GSM M8 (Verizon and Sprint are CDMA/GSM) in theory you should be able to flash a different radio to get the proper band compatibility, even if your model doesn't officially support the needed LTE band (unlocking of bootloader and S-off required).
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.
How to know which LTE band?
Hi!
I know that this has been talked before, but I could not find anything that works.
I have bought a HTC M8 dual sim in switzerland. Back in Argentina, I tried to make 4G work, and, of course, it doesn't.
I have read that there is some chance to change the band, by the qualcomm.
so.. how do I know which band(S) does my phone have?
Thanks in advance!
I use "LTE Discovery" App. Available on the Play Store.

According to this webpage, it supports LTE bands 3, 7, 8 and 20. And according to list of LTE bands by country on Wiki, Argentina uses LTE band 4. So it makes sense that you don't have LTE.
While radios are typically interchangeable among "regular" GSM M8 versions (s-off required to flash radios); this is not true for the Dual SIM. So while you are correct that band support is software based on the Snapdragon 801, the normal method to change bands is to flash another carrier version's radio. I don't think you have another version's radio to flash. Some folks have modified the the NV values on the CDMA M8 to change band support. But to my knowledge, nobody has gotten this to work on non-CDMA versions of the M8 (the changes just revert themselves after reboot).
I suspect you are out of luck. This is really something you should have researched before buying the phone.

I kind of did. This is an fantastic mobile, besides the LTE detail; and by buying it in europe I've spent less than half of its price in Arg. pitifully.. I need the dual SIM. So, still a win win.
I will try to modify the NV values with QXDM... maybe i still have some luck left.

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.
I switched from AT&T to T-Mobile and wondering if I need to flash the T-Mobile radio/firmware to get better signal. The phone is originally from AT&T so currently has their radio and firmware installed. Now that I'm on T-Mobile, do those need to be changed as well?
Thanks for your assistance!

If you search around (I think the AT&T M8 section) its been discussed a couple times.
My takeaway, is that it isn't necessary to change the radio baseband in your case:
For LTE, the T-Mob version supports bands 4 and 17; both of which are already supported by your current AT&T radio (and then some).
For 3G, T-Mob uses 850 and 1900, again both of which are already supported by your current AT&T radio. The T-Mob version M8 also supports 3G on the AWS band (1700/2100). At one time, AWS was the predominant band T-Mob used for 3G, but not longer. My understanding, T-Mob refarmed all their AWS to use for LTE (Band 4); so 3G AWS support is no longer needed or useful.
Now all of the above is just my understanding from the comments on the forums; namely from an owner of the AT&T version M8 that is using his phone on T-Mob (plus device specs, carrier info online, etc.). I don't personally use T-Mob as my carrier.
