Samsung Galaxy Nexus Variants?

Hi friends, these days buy a samsung nexus I9250 galaxy, but I wanted something:
1. few versions of the galaxy samsung nexus there?
2. There is a version that supports GSM networks lte? which is?
3. i9250 model supports HSPA + 21?
4. i9250 model that handles frequencies in HSPA +?

There are 2 versions.
1) CDMA/LTE on Verizon Wireless USA only. Model i515
2) GSM/HSPA+ (21mbps radio). Pentaband (works on any GSM carrier). Model i9250
And that's it! There are no GSM/LTE models.

As I noted in my post... they all support the same frequencies. Its pentaband GSM it'll work on any GSM network in the world.
For your reference so you can stop asking: http://www.phonearena.com/phones/Samsung-GALAXY-Nexus_id5595

I'm not sure, take expansys for example:
USA:
Network: HSPA+ 21Mbps/HSUPA 5.76Mbps 850/900/1900/1700/2100 / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)
UK:
Network: HSPA/WCDMA Europe/Asia: 900/2100 MHz / HSPA+ 21Mbps/HSUPA 5.76Mbps / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)
*Also, on Samsung web SAR page, there:
GT-I9250 GT-I9250J GT-I9250M GT-I9250T
from here:
http://www.samsung.com/sar/sarMain?site_cd=&prd_mdl_name=9250&selNatCd=US&languageCode=EN
So maybe there 4 different variant, also there a SC-04D for Japan,
SHW-M420S and M420K for Korea.
somebody have to check it , also the nexus S have plenty of variants, so I see nothing new here, but just go for standard GT-I9250 as it's pentaband 3G that will work in any country , BTW I dunno if GT-I9250* go with other build thank "yakju", not that it will do anything with the frequencies as it's software, but if you think of it, with other devices there mostly 2 main variants, 1 for Europe, and 1 for Americas, sometime also for China, and other regions. Anyone can get more info about it?

It doesn't matter what variation it is, a GSM phone will work on GSM networks and a LTE phone on all LTE networks. (unlocked, of course)
GSM and LTE have completely different frequencies so a GSM phone will not work on LTE networks and vice versa.
PS. HSDPA+ has nothing to do with the phone itself but if the network you are on provides you with it.

Its all just semantics and slightly different radio software. They are all the same. You can use ANY i9250 model on ANY GSM carrier in the world. Read my first post it gives you all the information you need in practicality.
The i9250 is regularly for sale from dozens of resellers. Just buy one ffs.

What did you mean by Its all just semantics and slightly different radio software?
you mean it's possible to disable some of the frequencies with flashing different radio? from what I learned here, software have nothing to do with the frequencies that device supports, only hardware (antennas) matters here. also the other variants, are made for specific operators, so a normal i9520 wins, as you not depend on Samsung or the operator for OTA updates, also I'm not sure if let say J variant get OTA with "yakju".

Not hardware radio, software radio. The different variants (yakju** models) have slightly different radio software for the regions they're originally sold in. All i9250 models support the same GSM frequencies.
These models aren't necessarily made for specific carriers but specific regions. Any i9250 can be flashed to yakju with images from Google if you prefer. You will receive OTAs either way, but may receive them slightly faster if you choose to flash to yakju.
Long story short, you shouldn't care. Just buy the cheapest one you can get, because if it doesn't come with yakju out of the box, it takes about ~5minutes to flash it to yakju and be the exact same (and no this doesn't require root or anything, you just unlock your bootloader and flash images, then it is completely stock).
So just to drive it home again: ANY i9250 you buy will work on ANY carrier in the world. The hardware is the same, and the software may be slightly different, but 100% changeable to your liking. Just buy the phone.

Ok, and I guess, lock the bootloader after?
I also buy it soon, and I also want to use "yakju" build, but dont want to root or unlock bootloader, but there is no way to flash "yakju" without unlock the bootloader?

*sigh*
Jesus christ what happened to the experimental Nexus spirit?
Why on earth even get this phone if you are afraid of touching it?
It's a phone designed to be ****ed with and still be bootable with code hosted outside it if you **** it up completely. It's virtually impossible to break.
How on earth can you even consider buying this phone if your main intention is not using what is what made for?
If you don't want all that, just get a regular phone, made for regular people, where you get your updates, regularly, through some really ****ty 3rd party "value-addon" software. Which only runs on 2 versions of Windows. And slowly.
Or just get your yakju/non-yakju phone and get the updates when you do, which will still be before everyone else.
Really.
You are putting to much into this. Either you want a moddable phone, and this one is it, or you are not a modder, and you should get something else.

That's quite a pompous rant. Shame you're so embarrassingly off the mark. The Nexus is a dev phone, because it is important to have a smoothly running device with the latest operating system out there for manufacturers and app developers. It contributes to the viability of the Android ecosystem (#1 reason the Nexus is made for). Hence the rapid OTA system on an incremental version basis. But you're full blown ego-crazy if you think Google released a phone just for you - the 0.001% that wants to mod. This is a mass market phone now (#2 reason it is made for). Most consumers buy it exactly so they don't have to root and install custom roms to stay up to date without the inherent bleeding-edge bugs that goes along with hacking. All Android phones are moddable. Why the hell wouldn't you have bought something with better specs if you were just going to mod it? You did it wrong. Sorry to break it to you, but Google made the GN without your specific hobby in mind.

You don't root. You do unlock the bootloader, but who cares! If you must have a locked bootloader, its just 1 extra command line entry to lock it again after you're done flashing to yakju.
Don't think you're understanding really. Unlocking the bootloader on a Nexus is not a big deal. It is literally 1 command line entry to unlock or lock. Like I said, flashing yakju takes literally 5 minutes.

I know that, but people here talking about the variants of it,
how can we be 100% sure, that for example M and J have the same hardware?
and only the radio software is different?!

You just know! Stop worrying FFS. I could hand you either one with flashed yakju firmware and you would never be able to tell the difference (even with regional software you wouldn't tell). No matter what, you'll get an i9250 that's what matters.

[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.

But also noticed this on the Amazon page:
4G LTE (1900 MHz) with availability in limited markets; 3G (800/1900 CDMA/EV-DO Rev. A frequencies)

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)
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
3G (850, 1900, 2100 MHz)
HSDPA 21, HSUPA 5.76
4G LTE (700 MHz, AWS)

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:
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??

The Amazon AT&T page updated to show following specs for network:
http://smile.amazon.com/gp/product/B00IZ1VNZ2
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.

F400S/K/L Versions (Hardware Comparison) and usage on AT&T

Hola folks!
After finding enough screenshots/video reviews, I am beginning to think that from a hardware perspective the S and L variants are identical (including supported bands), whereas the K is only slightly different from S/L.
Any images of the back cover off on the K models (Olleh) will show "F400 0425 K" indicating the hardware is the "K" variant. (If you watch the review video http://www.androidcentral.com/lg-g3-review, you will notice this info up at the top on the backside, right above the camera.) UPDATE: Here is another link with an image http://arstechnica.com/gadgets/2014/06/lg-g3-review-a-great-phone-with-way-too-many-pixels/#image-4
On the S/L (SK Telecom, LG U+) models, they say "F400 0423 S/L" on the SK Telecom model ("S" variant), and "F400 0425 S/L" on the LG U+ model ("L" variant). You can find images of the "S" model with engadget's review (http://www.engadget.com/gallery/lg-g3-review/2676959/#!slide=2676963), and images of the "L" model with ubreakifix's F400L teardown (http://www.ubreakifix.com/blog/wp-content/uploads/2014/05/ubif-g3-21.jpg).
(Thanks and kudos to the review sites and teardown site for the images.)
As an owner of the F400S, I can tell you that all 3 variants will run on AT&T LTE (as a lot of our LTE is on Band 17 - 700 MHz spectrum). I was able to load my F400S with the TOT and DLL files of all 3 variants (currently waiting on getting it back to the "S" variant once the DLL is posted), and all 3 variants will connect to AT&T with no issues (for those of you that plan on importing like I did).
So for those of you who managed to brick your new G3, as long as you can ADB into it, you can edit your build.prop file with the corresponding korean variant model info, and load any stock image. As @wolfgart has posted a great thread with the TOTs and DLLs, I recommend swinging through there for more info. If you have a K variant, load the K TOT and DLL, and you are fine.
For those of us with S/L variants--with the above info and enough tinkering in the hidden menus of all 3 variants, I can tell you that from a hardware perspective these two models are nearly identical. From a modem/supported frequencies perspective, the S and L variants support the exact same frequencies--meaning, if you bricked your S or L version, you can restore it with an S or L TOT and DLL (after editing build.prop if needed) and you will still get all of your original hardware supported bands/frequencies. This is critical for those of you using LTE Band 5 to connect to your data... (should not be the case for any US AT&T users...).
UPDATE: in the 'Android Development' section, wolfgart's thread with the TOTs and DLLs have been updated to now include the files for all 3 models. So unless you know what you are doing with a build.prop edit, probably best to stick with what came with the phones for those who are new to this stuff.
The main difference between the S/L and K phones in frequency/band support is that LTE Band 8 is supported on the K model only, whereas you will get LTE Band 5 support on the S/L models. All other bands and frequencies (WCDMA/GSM) are the same across all 3 models. All 3 also support LTE Band 17, and will connect to AT&T in the US.
Took me a while to figure this out, but I had a long weekend

Cool! nice to know, thanks for the well explained post

Any thoughts about the L/S version suporting LTE Band 7?
Thanks

Unfortunately, I don't connect to LTE with band 7 so I can't say much on that. However, just based on the hidden menus in both (I am using the L version on my S variant phone at the moment), they both have the same listings of 1,3,5,7 for supported bands.
LTE 700, 850, 1800, 2100, 2600 (Band 17, Band 5, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
The above are the fully supported bands on the S and L variants.
The below are the fully supported bands on the K variant.
LTE 700, 900, 1800, 2100, 2600 (Band 17, Band 8, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
I don't have the K variant on my device now, but I recall the only band difference is that it supports LTE band 8 (900 MHz) instead of LTE band 5 (850 MHz), but other supported bands are the same. LTE Band 5 is one of the primary bands for both SK Telecom and LG U+ (which partially explains why the two phones have nearly identical hardware, including modem support).
Hope this answers your question. As support for those frequencies are built in (and it makes sense on LG as a mass manufacturer--They can use the same modem and just rebrand it like they did in Korea for the S and L variants).

Why is the S one more expensive than the L?

That, my friend, is a question you will have to ask LG and SK Telecom. We sorta see that in the US every so often with "special editions" that aren't really that special and they will add an extra 100ish.
Off-contract, LG U+ is the most affordable right now, with SK Telecom right around $700 USD. With markup and shipping, etc. eBayers are selling it for $750-800.
Also, you have to remember the G3 is a hot commodity even in Korea right now. Had some friends who thought it was funny I got a phone overseas before they even bothered joining the bandwagon.
So though I can't say for sure why exactly it's more expensive, I can definitely say it has to do with the fact that the phone is still only 3 weeks old

And none of those 3 will work on T-Mobile LTE which needs 1700 and 2100Mhz most of time.
There are some spots with 900Mhz support though.
But as much as I want G3, I'll wait for the T-Mo version.

Yeah...I'm a proud owner of a Htc One M7...I have been thinking a lot and decided that it's time to change. I'm comparing the M8, the Z2, the G3 for a long time and finally think that this last one will be the one...unfortunately it's still very soon to easily find information regarding this phone online...
Your information helped me a lot...now I know exactly which variant to buy :fingers-crossed:...thank you guys very much

It looks like you are planning on doing the same upgrade I did. I still have my M7 as my backup , but definitely gotta say I am loving my G3.

That's amazing man...I've been a HTC fan since the Sensation...but currently I feel that they are been left behind...
I'm really sorry, but other brands are offering a lot more for the same price.
The HTC will always win in design and the quality of the phone's body, screen and, of course, sound!...but they are losing in the rest...UI, camera, battery life definitely...it's just sad
Nice to know that you're enjoying your G3...I hope I'll be as happy as you are in a few weeks...and judging by how much I've researched about it...I'm sure I'll love it!!!

question
sorry, which of these three variants brings FM radio? K, L, S, and if for example buy the K version, if you install the L or S variant fm radio works?

I´m about to buy a G3 and found some model have an antenna, is that correct?, anybody knows what tv frequencies can handle?. Thanks!

From my research, none of the korean models (F400 S/K/L) support FM radio. Instead of an FM radio tuner, they are offered with Korea's DMB tuner, for korean DMB support.
I have only seen DMB function while in Korea and Japan. Anywhere else in the world, you will have to check with local providers, as some countries will charge for DMB as a service (just like satellite television).
Hope this helps

The only frequencies it can support is anything broadcasted as DMB. Certain countries offer DMB subscription services, but you will have to research if it is offered where you live.
In the US, DMB is unavailable so I just have a nice long antenna that people crack up at in the year 2014, but completely unusable where I am. I just tell them its for better service as a side joke lol

Any of them will do. I would say go for the one that gives you the best price. At this point, enough AT&T users have gotten their hands on all 3 variants. Most can get LTE through band 17 (700 MHz) which is available on all 3 phones.

Will the D855 variant (with LTE 700MHz) be able to use on AT&T (band class 17) or Verizon (band class 13)?
Or to be more specific, will the D855 cover all 700MHz US band class (12, 13, 14, and 17)?
Thanks!

You would have to check which specific band class of 700 MHz the D855 would be capable of connecting to. As I do not have the D855, and specs are varied on the internet right now, I cannot say for sure.
The FCC had ruled four separate band classes to operate on the 700 MHz spectrum in America--Band 17 700 MHz capable modems cannot connect to any of the other 700 MHz band classes and vice versa. (It was claimed that they did not want to have any network interference issues. Carriers purchased the rights to access certain chunks of the 700 MHz spectrum, and they are isolated to those carriers only.)
I am seeing 700MHz (B28) support on D855 models, but I believe that might be related to certain LTE-A rollouts in Europe (meaning it may not be able to connect to current 700 MHz bands in the US (as the US does not have LTE-A networks at the moment) and new band classes are issued for LTE-A (i.e. Band 28).

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.

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.

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).

Anyway, have a look at this: http://wireless.fcc.gov/hac_documents/150813/9135276_21.PDF

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.
