Why no 3G with ATT

Having owned several HTC phones, it seems to me that if they want to be a leader, then why release the TP2 with no 3G speeds in the US market? I have read that there is some talk about a release on T mobile's carrier for a TP2 with 3G. If so, hey ATT get with it.

You've got it there. There is no US 3g on the euro devices as per basic agreements with the carriers to let their branded versions come out. The local carrier versions are coming so just hang on.

first of all, the TP2 wasn't released in the US market. the model that you're talking about that has no US 3G is the European model. some people just preferred to buy it unlocked and save themselves a lot of waiting time.
secondly, yes, T-Mobile is getting it around August 12 here in the US. you would know that for sure if you read the very, very numerous posts around the Rhodium forum. all the major US carriers are getting the phone, including AT&T, Sprint and Verizon. there are speculated release dates about the other 3, but they will come eventually.
to me, this seems like a redundant thread. just my opinion. I vote for thread to be closed.

fail...
why wouldnt att not have 3g with the fuze when they have 3g on older phones?.....

The better solution would be for ATT to embrace the same 3G standard that Europe and Asia have, and change to 850/1900.

850/1900 isn't Europe nor Asia, but North American bands actually
As for the "fail" comment or criticism:
The current phone available is the EUROPEAN model, it works in EUROPE. The same goes for many many other phone makers. They make dual band 3G phones (quad-band GSM) for Europe and then make the specialty ones for the US and possibly Canada.
Originally they tried to make 850/1900 the standard for North America, but so many companies are planning alternatives like 1700 and whatnot. It's like that one company in Australia using 850/2100 instead of 900/2100. If you HAVE to blame somebody it would be ATT for starting the usage of 1700 as a 3G band, or blame the lack of spectrum which caused ATT to opt for 1700.
To make a phone truly universar 3G-wise it would need to use 6 different bands, and personally I've only seen specs with up to 3 bands (though I heard about mysterious 3G 4 band phones).

ATT uses 850/1900 and are moving to add 2100. T-Mobile use 1700.
I agree it will be good if ATT does actually get 2100 going.

Oops, my bad, I get the two confused. And yeah, it'd be good if they had the 2100 going, especially if it meant interoperability, even if limited, with European models (and they could reap the benefits of charging for 3G data roaming).

Getting a T-Mobile phone to receive AT&T 3G

Is this possible?
We know that AT&T uses the 850/1900/2100 MHz US 3G bands, while T-Mobile uses the 1700/2100 MHz US 3G bands, therefore making each carrier's hardware incompatible with the other's 3G network, however I had a discussion with someone seemingly very tech savvy, who said this is most definitely NOT true.
He was certain you could flash an AT&T radio on an unlocked T-Mobile phone and get the T-Mobile phone to connect on the AT&T 3G network, and this is exactly what he plans to do once T-Moble releases the HD2/Leo this spring. He says from a hardware perspective they only stamp one type of chip at the factory, so it's the radio software that dictates whether the phone works on an 850, 1900, 1700, etc frequency.
Obviously there are early termination fees, and carrier penalties to consider, but from a pure technical perspective, is this even feasible?

no it isnt true.
countless people have tried to flash the g1 to at&t only to get edge and be disapointed.

It is sorta true. There was a phone that HTC released at one point in time that was only triband GSM which works fine with T-Mobile, since it only uses one of the American bands for its native network, 1900. Europe uses 900 and 1800 and so this phone (I think it was the Diamond Europe) was released initially only as triband GSM as well as Europe's 3G Networks. A while later HTC actually did release a radio update that unlocked 850 (which AT&T uses together with 1900 for its GSM network).
Of course my theory is that this phone was only scheduled for Europe release, especially sine it did not have any US 3G support in that varriant and due to a bug or whatever HTC's radio hid the 850 network. But because enough people imported the phone, or to improve roaming the bug or whatever was fixed and the 850 network supported.
However, this has never been done with 3G networks. Is it possibly, yes it could be. You have to remember though, that even though you enable AT&T 3G, the internal attenna needs to be able to pick it up as well so there is additional hardware design.
I'm gonna doubt this is possible.

Well then this person is only talking out of there ass. Making it not even feasible possible. The hardware is different. Go look at the fcc website. You will see the chips are not the same. Nothing to do with a damn "stamp"

Yeah not to use the big i too much around here, lol, but the best example is the Iphone. My wife has an Iphone jailbroken and unlocked to work on our Tmo account, and I spent a good amount of time figuring all that jailbreaking stuff out because it was interestingly similar to XDA's manipulation of Windows Mobile. I unlocked her phone. At one point I considered buying an Iphone and was really dissappointed to realize none of the Iphones on Tmobile have 3g. Althogh it sounds possible on some really technical firmware level, honestly theres millions of dollars going into jailbreaking iphones for the 30million or so on Tmo. And no one is getting 3g. Because it seems to be a problem that cannot be solved with some simple hack or crack.

Also go look at the radio threads. everyone flashes radios from any carrier looking for batt life and reception in their area. none of them seems to have magically gotten 3g out of their radios, or lost it for flashing the wrong carrier.

There is alot of things the iDont phone Dont do.

from what I have heard and seen though a friend who does development for blackberry, all the carriers use different channels for 3G. The software on blackberries show that 3G for ATT is channels 1,2,3,5 and 7 if I remember correctly. T-mobile has different ones and sprint+verizon the same. I don't think it's as easy as just swapping software...

When LTE dominates, will importing phones still be possible?

Importing phones is obviously possible now because tons of carriers all over the world share AT&T's GSM and UMTS/HSPA bands.
When LTE starts to become the dominant source for cell-phone signals (especially when Voice-over-LTE appears), will AT&T still share bands with the rest of the world like it does now?
In other words, will AT&T still have the advantage over Vzw and T-Mobile that early adopters of phones will be able to import them and use them months before they show up in the US? Or will the proliferation of LTE cause AT&T to suffer from the same problem from which Verizon suffers: You will ONLY be able to use phones designed specifically for the AT&T network?
I ask because right now I have AT&T and Verizon, and I have unlimited data on both. I'm going to be canceling one of them within the next week or so. Right now I actually prefer AT&T's service, and I love the fact that I can import phones that are not available in the US. But if the "importing phones" advantage of AT&T disappears, perhaps Verizon becomes the more desirable carrier for me.

You haven't read much about LTE, I guess. By conforming to the LTE standards, a multi-band LTE phone will be able to be as much of a "world phone" as a multi-band GSM phone. While there are some differences in frequency spectrums around the planet, there are many in common.
The allocated frequencies are 700 and 1700 MHz in North America; 800, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; and 1800 MHz in Australia.
So, a quad-band LTE phone with frequencies of 700/1700/1800/2600 would get you coverage almost anywhere.
The end result is this: If the manufacturers want to make an LTE "world phone" just like they have in the past with GSM, they certainly can (within the laws of physics, if the antenna technologies will allow it). The same economics apply for the manufacturers, and possibly better - since there are a smaller set of frequencies with greater chance of coverage - and a greater market potential for a single design.
I suspect that with modern fractal antenna technology, this won't be a huge issue.

In North America, are the 700 and 1700 different carriers, or is it better for a phone to support both like the current att 850/1900?

Thanks. That was actually pretty helpful. But for instance, it is my understanding that AT&T runs in the low-700s, and Vzw runs in the high-700s. And Vzw has tentatively stated that its LTE phones will not be compatible with AT&T's. So I guess when you say they could make a multi-band LTE phone, it would need to cover "all of" 700 MHz for it to have both AT&T and Vzw compatibility.
In any event, does this favor AT&T or Vzw for future phones? My guess would be for at least the next several years, if not decade or more, all LTE phones will have 3G radios in them as well. And those 3G radios, just like today, are going to be GSM. So I guess you could start seeing phones world phones that are both quad-band GSM and quad-band LTE, and theoretically these would work on AT&T, but not Vzw.
Am I on the right path here? Do you agree that it seems likely at least until GSM/3G completely die (if ever), most/all LTE phones will continue to have 3G radios, and this would suggest that if anything, importing international phones will still be possible on AT&T but not Vzw?

Almost every LTE deployment other than VZW runs alongside an existing 3GPP (GSM) network and most all chipsets will natively support the combination. Therefore, I doubt you will see many devices without the UMTS radios. No one is turning their 3G networks off any time soon. Verizon will be one of very few sources for LTE devices WITHOUT any other GSM radios.
As for LTE frequencies, there are A LOT of them. What chipsets will support which radio combinations is still a subject of much debate. Don't expect full interop out of the box.

You can always import regardless
the only risk you face is all the different LTE radio bands that you might or might not get with certain phones

Don't think so. Verizon version = CDMA + LTE. So it will only work in the US, on Verizon.

It's possible that the Verizon version has GSM/UMTS radios, it's also possible that it has those but are disabled somehow. We really don't know all that much about the LTE version of this phone, we don't even know the exact dimensions of it and what battery it comes with. So we'll just have to wait until it passes through the FCC or is released.

I do recall seeing a negatory on the world phone status in Verizon's inventory system. And I suppose there is still the option for dormant or disabled radios but I ain't holding my breath.

[Q] Does the quad-core HTC One X support AWS bands?

Hi, I'm seeing conflicting information on whether the quad-core (international) HTC One X supports T-Mobile US's AWS bands. Engadget and other sites are reporting that it does. But HTC's own specs don't mention it.
Does anyone have any light to shed on this?
Thanks, Alan

Yes, HTC One X will support Tmobile's AWS band
Hi, as we do know the T-Mobile HTC One X will debut in early April, for a yet to be released date, though T-Mobile didn't provide exact release date. As you mentioned that HTC' site doesn't give any clue whether it will support AWS band or not. We can say that it will be updated soon for sure, as well as T-Mobile reveals a release date. We suspect that HTC didn't show T-Mobile AWS band as the device is only available for pre-order from various retailers, so it will update it soon as well as T-Mobile reports.

I'd really like to know the answer to this question also. To add to the confusion, HTC's site for the AT&T version of the One X (Called the One XL) does show that it will support AWS: www.htc.com/us/products/htconex-att#tech-specs
It doesn't make a lot of sense to me why the AT&T specific version would support AWS for T-Mobile (never seen that before in an AT&T specific phone). In the past it was usually the international version that supported AWS. I don't see any of the various phone/gadget blogs mentioning this about the AT&T version either.

I don't understand what you're talking about here. There's no T-Mobile HTC One X. T-Mobile is getting the One S (the lesser midrange handset). That's what was announced at MWC this week, to appear in the spring.

For what it's worth, here's a rumor that T-Mobile will get the HTC One X in the summer (with the Tegra 3 quad-core cpu and stock Android even).
www.androidandme.com/2012/02/smartp...e-to-get-stock-android-4-0-and-quad-core-cpu/

I'm wondering myself does Tegra 3 Quad core support AWS band and if so does it support HSPA +42 or HSPA +21? Also is it the One X Terga coming to Tmobile Usa or One XL Snapdragron coming to Tmobile USA? Like another poster said the HTC website shows the AWS band for One XL under AT&T but no AWS band for One X under international version.

Come to think about it somebody posted the build prop file for the HTC Endeavor aka HTC One X and it did not list compatibility with AWS band.

This is a bit of speculation on my part, but it could be that AT&T ordered the HTC One X to be compatible with T-Mobile's AWS since they predicted that the merge was going to go through. Lets not forget that AT&T and T-Mobile do have new roaming agreements after the merger fell through.

That makes a lot of sense. Seems plausible.
Don't know if it means anything, but GSMArena now lists the AT&T One X as having AWS (I assume they probably just pulled it from the HTC site and I do find that GSMArena's stats can be a little unreliable):
www.gsmarena.com/htc_one_x_at&t-4614.php
I'd hate to have to have an AT&T branded phone to get AWS though. I like the unbranded phones.

Hmm. There's also this story, from yesterday (and spreading rapidly), that quad-core variant of the One X has cleared the FCC, headed to an unknown carrier:
www.pocketnow.com/android/quad-core-htc-one-x-gets-fcc-certified
And this rumor from a week ago that T-Mobile will get a stock Android version of the One X:
www.androidandme.com/2012/02/smartp...e-to-get-stock-android-4-0-and-quad-core-cpu/

From what I read this morning, international version of the One X will be with AT&T. Therefore, the chance of One X being available on T-Mobile dropped, but its not for sure until CTIA in May. Hopefully they'll announce something.
Other than that, T-Mobile customer may be able to use international version of the One X on T-Mobile someday. Since T-Mobile may or may not be refarming their 1900 GSM spectrum. If they do refarm it to 1900 UMTS, then I'll be one happy T-Mobile customer.

Where are you getting this? It's well known the AT&T is not getting the international version, but rather a different version with a Qualcomm dual-core processor, to accomodate AT&T's LTE network. Even HTC's own website list's a separate AT&T version of the One X, from the international version.
Also, if you look earlier in this thread, the AT&T version in the specs on HTC's website support's T-Mobile's AWS frequencies. So there may be more than one avenue to get a One X that works on T-Mobile.

First, I've worded it wrong regarding the international version. I meant to say that the international version is compatible with AT&T. Won't be offered on AT&T, but the UMTS bands has 1900/2100 on it so it could be used on AT&T.
HTC One X
I think I might have missed the AWS spectrums for the XL. Personally I don't think I would put too much hope into it, because the XL for AT&T is meant to focus on LTE. If you look on the T-Mobile Reinvigorated Challenger Strategy Presentation, AT&T's AWS also ties into their LTE.
T-Mobile's refarming their GSM 1900mhz, hopefully to UMTS 1900mhz. If that's the case, T-Mobile users will still have a chance to use One X or One XL on T-Mobile.
T-Mobile USA Reinvigorated Challenger Strategy Presentation
There's also rumors that One X will be coming to Sprint and to T-Mobile as the G4X. The time the possibility of announcement is probably in May.
Rumor
So I'm trying to hold out till May to see if I could see an announcement. If not, I think I might be getting the international version of One X, then wait patiently and hoping T-Mobile will hurry up and refarm the 1900 spectrum. There's also words that the refarming has already been going on, with more iPhone users noticing that they could get 3G speed.

Thanks for the further explanation and links. I could be wrong, but it still seems to me like the AT&T One XL might work on T-Mobile. If you look at the specs on HTC's website, you can see that it has AWS not just for LTE, but also for WCDMA (i.e. UMTS).
www.htc.com/us/products/htconex-att#tech-specs
I don't see why that wouldn't work with T-Mobile. As nickmgray points out above, it's plausible that AT&T specified the bands for the One XL, before they knew that the T-Mobile merger was going to fall through. Hence at the time, they may have wanted a phone that would work with T-Mobile's network.

I'm not holding my breath on the spectrum refarming being a solution for the One X. Unfortunately I can't remember where I first read about it, but my understanding is that it will take a couple years. At that point there will certainly be more compelling phones than the One X.
Also, if you look at the charts in the link you provide to the T-Mobile Strategy Presentation, you can see that even after the refarming, it appears T-Mobile will still be using AWS for HSPA+, as well as for LTE. So it seems that a phone that does not have the AWS bands could suffer significant coverage issues. T-Mobile's goal in the document seems to be to make the network better for in-bound international roaming and more compatible with devices from other carriers. But a phone without AWS for a U.S. resident would still be limited.
It would be nice though if international and AT&T phones were fully compatible with T-Mobile's network. That would give T-Mobile a nice advantage with handset options; and a good way to tempt away AT&T customers (who could then keep the phones they already have). But, again, it seems like this is something for the future and not a way to count on using the One X with T-Mobile.
I'm hoping HTC will just make an international version with the AWS bands, as is the case with the Sensation. Or it would be great if they put a pentaband radio in the international version, like Nokia has been doing for a while. Or maybe the Tegra-3 One X for T-Mobile rumor will turn out to be true.
I actually like the size of the One S better. But it's not worth it to me without the 720p resolution and 16 Gb of memory (without a microsd expansion slot).

Just looked at the FCC's documents on AT&T's One X.
The document doesn't mention testing any of T-Mobile's bands. Don't know if they didn't test it, or the phone don't have it.

Thanks for the link. I'm not sure what to make of that. For example, they only list GSM 850 and 1900 frequencies. It would be really unusual for a phone these days like this not to be quad-band GSM. So it seems like the FCC report is probably not listing all the bands the phone can operate on, only those that it will use with the AT&T network. I'm not sure this really answers the question about AWS in the AT&T One XL.
What about the One X with the tegra-3 processor that went through the FCC? Do you know where the report for that is? I can't really see how to search the FCC website.

Thanks for the link. Again, this doesn't really indicate that T-Mobile is completely refarming HSPA+ to 1900 Mhz. It just says, "A nice side benefit of the refarming effort is that our 4G network will be compatible with a broader range of devices, including the iPhone." The fact that more different devices will technically work on the network, does not mean that they will get the same coverage as devices that work on both 1900 Mhz and AWS. As the other document you linked to indicates, after the refarming HSPA+ will be on both 1900 Mhz and AWS, so it may mean that if you want the best coverage on T-Mobile's network, you need a phone covering both frequencies. Time will tell I guess, but it doesn't seem clear yet.
And, as I said, this is so far down the road to completion (they're starting now, but it will take a couple years to complete) that I don't see it as being a good solution for using a One X that lacks the AWS bands on the T-Mobile network.

Took a while, but I found the international version of the One X on FCC.
One X FCC
Looking at the model number and matching with other site, it looks like it's the one. The only problem is, it doesn't show any frequency testings. I also looked up the One S and found 3 model numbers, seems like only the one coming to US is the one with the frequency testings.

Thanks for finding that. I guess we're just stuck waiting to see what's what when the devices actually get released.

Network Modernization

Hey guys I was wondering if anyone knew what network modernization meant for us as phone buyers. I am really interested in picking up an S3, but want to continue to use my web2go/tzones plan. I was considering buying either an AT&T or international version and saw http://blog.t-mobile.com/2012/06/14/fast-progress-on-4g-network-modernization/ this article and was wondering the implications. Will the 1900 replace the 1700 in HSPA+? Does that mean phones that work on AT&T(1900/2100) will now work on Tmobile(1700/2100)?
Thanks for any info you guys can provide!

That is correct. Once the refarm is complete we will be able to use phones with the international att bands at full speeds on tmobile. 1700/2100 will be used for LTE

I would not get the AT&T or International version just yet. It is quite likely that you will experience slow speeds due to lack of proper frequency support at this time. Eventually T-Mobile's HSPA will be moved over to the 1900 band, however, this is a transition, not a on/off type of thing. There will still be HSPA on 1700 bands for well over a year from now, probably more like two. I think it will be a mix of 1900/1700 bands for HSPA in a couple of years, with LTE in the 1700 band exclusively. So, if you get the AT&T version now, you should hope that your city or region is one of the first for the transition, and don't plan to have good support while traveling. If you are on T-Mobile, you will have to choose great HSPA support now with no LTE ever (T-Mobile version), or no HSPA support now, and maybe some mixed LTE and HSPA support down the road (AT&T version; no LTE on International version).
I would personally get the T-Mobile version if I were you. LTE is not going away, and there will be plenty of LTE phones on T-Mobile in a couple of years. But HSPA has great speeds now, and will still have decent speeds in a couple of years.

The T-Mobile version already supports HSPA+ over 1900 MHz..so it's ready if you're planning on using it on Tmobile.

Just when I thought about dumping T-Mobile, looks like they might be heading in the right direction.
