    If you buy the Quad core version of the HTC ONE X it will not work in North America. I bought it and was told it would by my carrier. After contacting HTC tech support they advised that only the Dual Core will work in the United States.
    I'm out $650.00.

    Hello Cherine!

    Who is your carrier? It works on GSM bands (big ones are AT&T and T-mobile) just fine.
    Sprint, Verizon, US Cellular, and other CDMA banded carriers will not work because it is a different technology...

    You are wrong as wrong gets. I have a international one x and it works perfectly on att.

    Yes, there are plenty of GSM/UMTS networks in the US that work with the international version - I have used my GSM phone frequently when visiting the US, but I think Verizon and some other networks ijn the US use a different system and some of those are 4G, so you need an LTE version of the phone.

    And even the LTE's are not cross-compatible; Verizon and AT&T are working hard to keep their devices off of each others' LTE networks...

    Does the US version (dual core) have any hardware that would make it run faster on AT&T LTE network, or did AT&T just completely drop the ball and cheap out big time?

    Welcome to AF!

    Not sure what precisely you mean... It has the proper LTE radios which makes the download speeds faster, and they work better (less battery drain) because they are integrated with the CPU, and it has a next-generation CPU that although dual-core has been shown to equal and in some instances best the previous generation quad core - excepting in multi-threaded applications.

    So I guess no matter which aspect you meant by "faster" the answer is "yes," but without knowing costs involved I would say they did not cheap out...

    Thanks for the warm welcome. I was trying to ask if the UK version is a better phone in general and also trying to determine if they left the added "LTE features" of the US version out of the UK phone? I live in the US, which one should I get (putting contracts and money aside) ?

    I would (and am) getting the AT&T version, but I am on AT&T so that is an easy question for me to answer for myself. I would check coverage where you live & work, because T-mobile might have better coverage (and your decision would shift to UK version or their HTC One S which has the S4 processor but a lower-res screen), or not the UK version at all because Sprint has a version they are releasing. Were I in your position I think I would start with coverage, and once I had the available options pegged down that way I'd start to look at specs.

    Just based off of what I have seen with reviewers comments and amidst the hodgepodge of benchmarks, I think anything with the S4 processor would be the better choice. nVidia's t3 is a powerful chip, but most apps/games out there are not coded to make use of it yet. However, there are "rebuttal" posts and videos showing the T3 winning, and benchmarks are really subjective anyways, so that is really a wash. When running processes that can be handled using the dual-core the S4 will trump the T3 because it is a more advanced architecture. Both are much more than adequate, and it seems many reviewers of both devices have commented that the S4 version feels smoother to use. The S4 also features built-in LTE, which is the future of AT&T's network, so it would be a future-proofing choice in that respect- despite the dual core (as opposed to quad core).

    Lastly though, I would factor into my choice whether AT&T's version would work for your planned usage of the phone. I don't think there are any features of the T3 (UK) version that are missing in the S4 version- but it would not surprise me if AT&T did remove some features (I can not think of any that they would, but if it is something they can charge for I'm sure they will replace it with their own version). So you might want to see/play with their version first (gets released sunday)before you decide.

    does the 3g or 4g works?

    The international version works fine with ATT. It works with both 3G and HSPA+ which ATT calls 4G. It does NOT have the faster LTE speeds.

    I decided to go with the quad core international version because my city doesn't have ATT LTE yet, it was out earlier and IMO a quad core will run multiple programs/widgets better.

    The dual core One X could not be further from a cop out. ;) :)



    ATT is splitting its high-speed support in thirds. The international One X won't work on the LTE network, but that's only a part of their 4G game.

    If you live in the US, the only thing that you may miss with the ATT One X could be root support. Otherwise, for performance, battery, and support, the ATT One X is a great choice.

    If you're going to consider CDMA, the Sprint version of the One X is the Evo 4G LTE. For T-Mo, you want to consider the One S, and for Verizon, no word on that.

    How can you compare those phones to eatch other?
    "HTC ONE X -int" has quad+1 core cpu and 12 gpu core's.

    everything else can be compared, but the "HTC ONE X -int" is out of the league.

    I can compare them because I am intimately familiar with the both core processors.

    The S4 may only have 2 cores, but they are about 40% more power efficient due to being manufactured with a 28 nm process. Further, the cores are basically A15 class rather than the A9 cores found in the Tegra 3 quad. Much more horsepower per core. So comparing quad vs dual cores without looking at the whole picture is like comparing a V8 engine with a V6 without considering displacement, horsepower, torque and fuel delivery.

    For day to day tasks, note that the S4 is using separate cores for video and media as well as the user interface than the GPU. I believe that quite a bit of that info is in the linked data I provided.

    The Tegra 3 I would expect to perform a bit better on heavy duty games.

    Right now, it appears that HTC is still fine tuning the quad core kernel.

    Otherwise, were I to give you a day to use each one for most anything else you can imagine and then ask you which was the quad, you'd likely only have a 50/50 chance of guessing correctly which was which. ;) :)

    I would submit that a One X is a One X and the blogosphere is virally selling people on meaningless synthetic benchmarks and buzzwords. ;)

    For each sort of thing where the international will excel, you'll find another where the ATT model does better. In the end, it's a draw.

    Mine is working fine on at&t, not sure what op is talking about? I don't live in a lte market so I don't need the S4 version as this international version works flawless.

    I have not been able to get any updates to help with the horrible batttery life with the original 1.19.707.1 software that came on the phone brand new. Does anyone know how to get the updates for this phone in the US. I think it can be a real nice phone but it is worthless with the horrible battery life it is getting right now. Any help would be greatly appreciated. Thanks. 532rat.

    Have you been able to get the software updates yet. I am stuck on the original software and it gets horrible battery life. Let me know if there is any thing special that needs to be done to receive the updates in the US. Thanks, 532rat.

    If you are going to compare the two versions, let's not forget the international version has 32gb vs. north america's 16gb and is available in both white and black (important to some users, especially those of us who work with our hands).

    T-mobile data will not work because HTC one x has GSM 850 / 900 / 1800 / 1900 does not have 1700. you need old micro sim card with code 50.01 then you'll have data but not 4G!

    Ive just returned from Florida and took my unlocked One x with me. Purchased a micro sim from tmobile for 60USD but couldn't get data to work and international calling although set up on the sim didn't work either. You above person is right. It seems to be connected to the type of micro sim....

    Does the HTC One X (AT&T) work on Telus network? Its a CDMA network here in Canada, and I have about a year and a half left on my contract.

    Anyone that could provide some information would be much appreciated.

    Sorry at&t uses GSM not CDMA so the answer would be no.

    The One X+ will be coming out in the USA to AT&T with 64 GB of memory and LTE data speeds before the end of the year. But I was rather annoyed that the initial One XL came out here with only 16 GB and, since I use my phone for music listening and most of my time is spent out of AT&T LTE coverage, I passed on it.

    I'm going to buy an International 3G version with 32 GB from a friend and try it out for a while. I have a AT&T SGS 3 right now, but I'm not a big Samsung fan so I want to give this One X a try and see how I like it before I commit. From all I've read and seen I agree with EarlyMon - the S4 and the Tegra 3 are about even for the day to day stuff I use it for. So I'll see if I'm still the HTC fanboy I've (mostly) always been and give the wordly version a spin for fun. :D
