The purpose of this post is to inform those seeking to use the HTC One on AT&T should NOT use the T-Mobile version of the HTC one on the AT&T network due to poor reception issues. Issues may arise from the enabled 42mb hspa+ and/or the inclusion of the 1700 band. Or maybe its just the T-Mobile radio.
I was originally on T-Mobile with a T-Mobile HTC One in Atlanta, Georgia. T-Mobile's coverage wasn't working out for me in buildings so I SIM unlocked the phone and took it over to AT&T. Everything works but AT&Ts coverage was always changing from 1 bar of LTE to barely any bars of hpsa+. I got a AT&T branded HTC One and inserted my SIM and got 2-3 bars of LTE when I was getting either none or one bar of LTE service. I am also getting about 90% more LTE coverage than I previously had with the T-Mobile HTC One on AT&T's network.
I took back the AT&T HTC One as I could not afford to pay full price for the phone at this time. I am still using the T-Mobile HTC One on AT&T and will buy one when they get cheaper.
On a side not my wife has a T-Mobile IPhone 5 and got it unlocked and switch over to AT&T with me and is getting comparable LTE coverage as the AT&T HTC One version. It sucks cause she will have 3 bars of LTE service and I will have 1 bar of hspa+. I wish there was a fix for this rather than having to go through selling the old one and getting a new one. I love my HTC One .
Title says it all, is it possible now that we have S-off?
I'm not sure what difference there is except for cid
I personally think it would be better to make it into an international version for timely updates.... I've been wanting to do this as well...

I don't live in the refarmed area so I only get edge, I can travel a mile and get HSPA+ though but I want something that is consistent. Not just random 4G in one corner of my house and Edge everywhere else

I do believe Att version is the same as international as far as radio goes. I think tmo radio is only capable of picking up all the tmo 4g.... Does your area have lte?

Nope, when T-Mobile rolled it out they skipped Jacksonville Florida
All one versions have the same hadware! It's just a matter of enabling/disabling a certain radio in the device

AT&T version does not support 3G AWS network which TMO does. LTE support is identical.

That's what I thought I read elsewhere
what he said above. TMO versions can pick up 3G AWS since most of their network is on that band. ATT doesnt use that band only 1900 for 3G, but since TMO has only started refarming old 2G 1900mhz signal to 3G signal only certain places will recieve 3G signal for TMO on the ATT HTC one.
So far i havent heard of anyone breaking into the radio portions and adjusting the bands. i think people are still a bit sketchy on whether that will work or not. its a pretty big gamble.
your best option is maybe find someone who has the TMO version and wants an international version. and trade?
I have the AT&T One. T-Mobile was sold out and I wanted it the day it was released so I just bought the AT&T One at Best Buy. I have AT&T LTE but I was wanting to use T-Mobile because I have unlimited on that line. I never get 3G though, only HSPA which is weird, or maybe not idk
To start with, kudos for this site. I have been reading it many times and am amazed at the community of developers around here.
Secondly, I searched but couldn't find my answer anywhere. And lastly, I apologize to the moderators if I posted this in the wrong place.
Anyway, here is my question: I have 2 HTC One right now, one is from Sprint and the other from AT&T. Here where I live, Sprint will only go on GSM networks but AT&T goes on the 4G LTE network. Both phones are unlocked since I am using them in Canada.
Is it possible to flash the Sprint phone with an AT&T Rom so I can force it to go on the 4G LTE network like my original AT&T does? I am in the impression that there are not many different phones except many carriers have specific bands that they use.
MAny thanks to those who will guide me in the right direction.

no you can't flash a gsm rom on to a sprint phone. sprint is cdma. you'll mess up or brick your phone.

You may want to list your specific carrier, but pretty sure Sprint's One only supports 1900MHz-band LTE.

This is correct. The sprint One will not be able to use AT&T's LTE on 700mhz.
Can't understand something.
I am on Virgin Mobile. When I use the Sprint phone, it says GSM as my connection. When I use my AT&T phone, I get either 4G alone or with the LTE symbol below it.
Both phones has the same menu when I do the *#*#4636#*#* so can someone explain why I can't get 4G on Sprint using the same SIM card?
I thought they only made one phone and added the rom that best suited the carriers.

Nope, it's much more than just software. There are several models of the One that HTC manufactures so they can optimize the antenna design to various regions/carriers.
The Sprint model can connect to the following frequencies (link):
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/ HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

I wonder than why it doesn't connect any higher than GSM? I mean Virgin has roughly the same frequencies as Sprint if I go by the chart you provided. Never thought this was going to be that complicated...
Hope I'm not hijacking this thread, but I'm also interested in trying to flash a WWE rom (non carrier specific) to my phone, while I do have a sprint htc one. I reside in a region that only utilizes GSM so i don't need support for CDMA. Higher up in the thread someone stated that doing so would lead to bricking the device, but has anyone ever tried?
You can get psuedo-4g on gsm using the sprint model, you just wont be able to tell because it will only say gsm. 14.4mbps is the 4g you get with att unless it says LTE along with it, then you are connected to att lte.
The sprint model only has the LTE radio for sprints LTE in the USA. If you slid a tmo sim in your att phone, it wouldnt be able tp connect to LTE eother since they ise different bandz as well.
Hope that made sense

Yes, many have done that. A quick search in the general section will turn up several threads with a similar title of "I accidentally flashed a GSM ROM on my Sprint One and now it's bricked." The solution is to ruu back and you can get it working, but I WOULD NOT FLASH ANYTHING OTHER THAN A SPRINT ROM FOR A SPRINT PHONE.

So then...whats the problem you seem to believe sprints version is the only one without att LTE, when in reality, the inly one with att LTE is the att version.
You cant flash a tmo rom on your att version even though theyre both gsm.
You cant flash a verizon rom on your spribt phone even though theyre both cdma.
Like i told you, 14.4 mbps is HSPA aka "4g" on tmobile and att. And you keep saying "it only goes upto GSM". Do you even know what youre talking about? Put the sim in your sprint phone, you will get "4g" GSM speeds. Use an app like sppedtest to try it out. "4g lte" means you are connected to the lte network.
If you get wifi everywhere you go, i honestly dont understand the point of this thread.

Exactly. I don't even know anymore if I have had a straight answer or not!
I found a link somewhere on this site that shows Sprint phones in their lonely category. I guess it does look like the Sprint HTC One phone was made with leftovers, sort of the black sheep of the family.
I so wanted to be able to transform it in a 4G LTE working phone but now, it looks likes it's a pipe dream after all:crying:.

Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

Yeah thats what im thinking. I need to contact and t-mobile rep and see if the re-farmed LTE here. Ill call and ask.
Alright so i called the rep and he said the area i am has been re-farmed to the 1900 range and i should be getting at least HSPA/3G but im not. Very odd issue

Verison use the CDMA, maybe that's why you can only use 2.5G network, just like some phones in China, they only have GSM in common

yes but this phone has 4g lte already in it which accepts the sim card. Also, i have seen other verizon htc ones with t-mobile and never had a issue. I fell i may have to use a custom rom.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.
CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.
Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.
I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

I'm thinking about picking up a used Note 3 to use on my AT&T account. Is there any reason to get an AT&T branded note over T-Mobile branded?
I can SIM unlock the T-Mobile, but would have to deal with locked bootloaders with AT&T. All the supported bands are there using the T-Mobile on AT&T, right?

I used the T-Mobile Note 3 for a while. I unlocked it using Chanfire's app. When using my AT&T sim card in it, I found the LTE to be horrible, despite supporting band 17 (700mhz) In places where I had average LTE on the iPhone, the TMO N3 would be on H+ or have the worst LTE signal. This was frustrating. I took it back. It was fun to flash roms and kernels though.
I got an awesome deal on a new AT&T note 3 where I couldn't pass it up haha. At first I noticed my AT&T LTE signal was not as good as it should be. I then created a thread about it. I cleared the cache in my phone and did a full factory reset. Now my LTE seems fine. Constantly sitting on -93db on my desk where my iPhone gets the same.
I'm pretty happy now with my AT&T Note 3. Rooting was so easy and gives me everything a custom rom would.
Yep, the LTE (band 17) on my N900T is horrible. My neighbor has N900A and we compared them side by side (with punching *#0011# and monitoring signal on both devices) and my N900T was always showing signal that was ~15db lower than the N900A. Gonna sell it. Will wait for Xperia Z2.
I agree completely with Matt and bormasina.
I just sold my N900T and bought a N900A and have noticed a dramatic improving, specifically in LTE bandwidth.
Hands down, the AT&T version performs better on an AT&T network. Go figure.

Yeah. Is it a coincidence that the ATT version perms better on the network it designed for? I'm sure ATT optimizes their signals in their phones for the proper frequencies.
I'm actually sitting in a place where my N900T would sit on a -105dbm signal and right now my N900A has been locked on a solid -89dbm. Night and day difference.
Go with the At&T version. The T-Mobile version is fine though if your on their network. But AWS still does suck in general when it comes to signal strength.
