US Touch Pro 2 Unlocked

Anyone know if they will be releasing an unlocked version for the US carriers? I would get the European version myself, as 3g isn't a big deal for me, but what gives me concern is the Wall charger doesn't include a US plug. Im sure this is a small deal considering i could proly just buy a standard HTC charger, but im just curious if they will be having an unlocked that will both include the US charger, and work on US 3g networks.

no word yet hua?

Why do you think the European model won't work on U.S. 3G networks?

European 3G I believe works on the 1900 MHz band (supported by the Touch Pro 2). U.S. 3G operates on the 850 MHz band (also supported by the Touch Pro 2). By technical standards, this should work fine in the U.S. on the 3G band.
As far as the charger goes, yes, that is a concern. But I don't doubt that somewhere in your house you've got a miniUSB charger lying around. If not, your local Wal-Mart/Target/Radio-Shack/Best Buy will have a million of them.

I have been on a number of blogs for the TP2 and they are seem to be in agreement that the European TP2 will only work over the EDGE network in US...
Personally, I am currently an iPhone user, but my wife is driving me crazy waiting for this US version!

Here is a good story on MSNBC.com on the various 3G standards. It is dated last Sept. but it is still good.
http://www.msnbc.msn.com/id/26511322/

uk/europe model will only work on edge in US. devicewire have done a detailed review on a europe model and could only get edge. to get 3g will need to wait for official model for that region.

Actually you have it awry. European 3G runs on 2100mhz not 1900. U.S 3G runs on 850/1900mhz.
If you go to HTC's site, the TP2 Euro model will do GSM/GPRS/EDGE on 1900mhz. SO if O.P imports a Euro version, he could use it on EDGE or he could just wait for the AT&T version. T-mobile USA's 3G runs on 1700mhz though.

T-mobile USA's 3G requires both 1700mhz and 2100mhz. Suppose to be hear around July 22nd...

Standard mini usb cables, yes and i also am aware i can also just charge the thing using the included USB cable. What im asking about is the WALL charger. If HTC uses thier standard USB-mini cable that is on a good chunk of their devices, including the HD/ Tilt/Diamond ect.. im sure finding a US charger wont be that hard.
Also, i was asking about an Unlocked US version, i do not intend to get one though the carrier as i dont want a modified version that they lock down. Nor do i care to wait till the fall when AT&T gets off their duffs to finally release it.
In any event, im just keeping my ear open and seeing what the grapevine heard about it.

Sorry guys. My bad.
I was confusing the specifications thinking that HTC would at least be smart enough to include full support for all markets. I was reading the Quad-Band GSM as support for HSPA/3G bands. I was totally bypassing the HSPA/WCDMA dual-band specification.
Chalk it up to a mix of wishful thinking and childish excitement. That does, however, kick the crap out of my week. Only HTC can bring me down this hard.

Well, I guess ATT got approved for theirs. Now the only question remains is, will their be an unlocked US version that supports 3g? or will we have to get the European version?

I'm in Taiwan for Computex and am so tempted to buy a touch pro 2 here. I would wait for the AT&T version but after seeing they changed the keyboard I want the HTC model. Only reason I haven't picked one up yet is because it only gets edge in the US on AT&T.
Does anyone know if the hardware cannot physically work on at&t's 3g bands or do we just have to wait for the at&t version to come out so the radio can be copied over or something. Thanks!

The hardware physically cannot handle it. The Euro/Asian model only supports 3G on the European and Asian bands which are completely different frequencies from the ones used in the U.S. It's definitely not just a matter of software.
And I think we all need to be clear that no one has any idea what the AT&T keyboard will actually look like. The promotional material we have all seen and discussed ad nauseum is a slap-together of the HTC mockup with AT&T's promotional verbage. Even the promotional bullet points list that the "HTC Fortress" has a 5 row keyboard while the mockup picture shows a 4 row keyboard. That picture, at this point, means pretty much nothing at all.

I see, Ill hold off then. Its kinda hard to justify ~$800 on a phone here anyways that doesn't have a warranty in the states. Thanks for the help!

Will the US Unlocked Version have the secondary VGA camera for video conferencing like the European one does?
What is the advantage of getting a carrier specific phone (AT&T or T-Mobile) as opposed to a US Unlocked phone outside of price?
I'm currently with Sprint and want to switch to a GSM provider.

no, the us carriers don't support that feature => no front facing camera.

the carrier phones usually come with some sort of branding (software: e.g. sprint tv application / hardware: different battery cover, different keyboard layout and so on)
This can either be an advantage or a disadvantage...

Stupid Question - Tmobile TP2 radio on ATT 3G

I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.

No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much

no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.

One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G

I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.

let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).

when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.

oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.

seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

American T-Mobile Touch Pro 2 and travel

the t-mobile rhodium supports UMTS 1700 and UMTS 2100 so if canada and/europe use those bands for UMTS (3G) then yes it will work. If not, the device is quad band GSM so no problem using voice and EDGE for data.
Also make sure the device is unlocked if you plan to put another carrier's SIMcard in the device.

Not sure about Canada...but TmoUSA 3G bands are different than Euro-3G.
Unrelated, but worth mentioning: the T-Mobile USA international roaming charge for data is steep -- $15/megabyte.
If you got a Euro sim card that would fix the $, but not the radio (for 3G).

The T-Mobile version supports AWS and 2100 3G so works fine in Europe and most other locations. Had 3G T-Mobile and 3G Orange in the UK, but I would suggest a local SIM too. For the UK, both T-Mobile UK prepaid and Virgin UK prepaid work in a locked T-Mobile TP2 or get it unlocked for more choices.

You used a T-Mobile USA version of the TP2 in Europe and had a usable 3G data connection?? Hmmm...that's the first I've read of this.
If this is well-known (and if so, maybe I'm just clueless ) can you provide a link to more discussion, that is...uhh...evidence...of it? Not about what bands the USA version supports -- I know that part -- but other reports/disucssion of it actually working.
On the other hand, are there any reports of a Euro-TP2 that can work on 3G bands in the USA?

USA TMO TP2 will work on TMO 3G in USA. It may also work on WIND Mobile for 3G data here in Canada, not sure about voice as they are using some strange network setup.
As the phone is UMTS 2100 capable, it will get 3G data and voice in most places in Europe and Asia.

Check the specifications. It supports both 1700 and 2100 UMTS. That means it will work in Europe. ALL Touch Pro 2's have 2100MHz UMTS and quadband GSM, every single one of them, including the CDMA ones. The carrier specific ones add certain bands.
European Touch Pro 2s have UMTS 900
CDMA Touch Pro 2s have CDMA bands
T-Mobile USA has 1700MHz AWS band
AT&T has 850/1900MHz UMTS

TP2 overseas vs versions
I believe, as I've use phones often in the US and overseas, that T-mobile uses 1700 UMTS in the US, but that their TP2 is also 2100 UMTS. Just as At&t Tilt uses 850 & 1900 UMTS (At&t requires both frequencies), but also has 2100 UMTS. As such, both should work in most European, African and Asian countries (verizon and sprint you,re mostly screwed).
I believe the older Tytn II (tilt) was sold world wide as a 850/1900/2100 phone, so you could basically buy it anywhere and use it here on At&t only for 3g or T-mobile Edge only. Unfortunately, the TP2 is sold mostly as a 900/2100 UMTS worldwide outside the US, so you are stuck buying the US versions that correspond to the US networks. The bonus of the At&t tilit 2 version is that it is 850/1900/2100, so it will work almost anywhere. The drawback of the T-mobile TP2 is that 1700 is used by almost no one and while you can use it in most of the aforementioned places, you can't use it in the Americas outside the US & Canada.
Check out this handy wiki UMTS page: en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
Just a note, I almost always pick up a pay as you go sim in other countries- much cheaper and very little hassle. Worth it for anything over a week stay. Maybe not as much so in some of Western Europe.

That is correct. Apparently they are only able to have 3 3G frequencies (though NTT DoCoMo is currently working on a chip that can handle 8 frequencies!)
At first Europe only used 2100MHz 3G and AT&T had set up on 850MHz/1900MHz. Since those were the only 3 bands, HTC would put all three of those bands in its phones up to the Tilt (Kaiser). Once they made the Raphael though, there was 900MHz 3G in Europe and T-Mobile had chosen the AWS band.
Since they can apparently only put 3 bands in, and Europe now needed two for 900MHz/2100MHz, they could no longer put but of AT&T's frequencies in. So they must have just dropped them.
The AT&T version (FUZE) has 850MHz/1900MHz and also has 2100MHz, which is the dominant band for 3G in Europe. I am not sure if they are using 900MHz there yet, but they decided that was more important to put in the European ones than AT&T's bands.
T-Mobile's 3G phones get AWS and 2100MHz. I think AWS might use 2 of the bands because it is split on 1700MHz and 2100MHz (but a different 2100MHz apparently, maybe low 2100MHz vs high, I'm not sure)

It doesn't just support 1700 and 2100, it uses both to work: 1700 for up/send and 2100 for down/receive. So, how does the Tmo USA radio cope without 1700 band for up/send when it's expecting it?

So, the full story (?) is that T-Mobile uses 1700+2100 (up/down) in the USA (which is what I already understood/knew) and in addition to that pair there's a separate slightly-different 2100 band that's used outside the USA? -- That, I didn't know.
If that's the explanation, that makes sense. But confusing that there's 2 different 2100 bands...
I may have to use some frequent-flyer miles and go check it out...

According to Wikipedia, UMTS Band I (commonly known as 2100MHz) uses 1920 - 1980 for uplink and 2110 - 2170 for downlink while UMTS Band IV (AWS, 1700MHz) uses 1710 - 1755 for uplink and 2110 - 2155 for downlink.
Band II (1900MHz) uses 1850 - 1910 for uplink and 1930 - 1990 for downlink and band V (850MHz) uses 824 - 849 for uplink and 869 - 894 for downlink. The uplink and download for these are close, unlike bands I and IV.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
I just assume they are only able to have 3 different frequencies since I have yet to see a UMTS phone with 4 frequencies. But as I wrote this, I'm not too sure because there were phones with Band I, Band II, and Band IV which would mean that there are chips capable for 4 different frequencies? Who knows, maybe someone with actual technical knowledge about this can say.
Also according to that page, there are five different UMTS bands deployed across the world. A bit of a pain. That is more then GSM ever had and who knows if it will grow to even more. LTE also will be coming in before GSM is phased out, so we are going to have to have phones that have GSM, UMTS, AND LTE. GSM will be no problem, quadband has been standard for a while, but having a phone that has both your carriers UMTS and LTE frequencies is going to be tough unless you buy it from your carrier.
What they should have done is just used the band names, and not their frequencies. It would be much easier to know that Europe runs on band I and T-Mobile USA runs on band IV and the T-Mobile Rhodium supports both Band I and Band IV.

ATT 3G Help me

OK call me foolish but I got fed up with TMobile and switched to ATT because the company offered to pay my data plan to keep me on call. I had been saying no but a billing problem that they refused to fix left me steamed. Anyway, is there anyway to make AT&T 3G work on my Tmobile TP2?

T-mobile is only edge...you cant use 3g unless you have a tilt 2

Let me rephrase that, for all the people that got "confusimacated" at first glance (like me)
The T-Mobile TP2 will work on AT&T's system, but it will only be capable of EDGE, and not 3G due to the fact that AT&T's and T-Mobile's 3G service use different frequencies.

Overseas Version
I have the overseas HD2 (LEO) which in not branded by T-Mobile. I also have ATT, can i get 3g on it?

at&t 3G is on the WCDMA 850/1900 megahertz bands. The Leo operates on EU frequencies, 900/2100 WCDMA for 3G service. Your Tmobile gets 3G on the 1700 MGHZ band. You need a phone with NA 3G frequencies to get 3G from at&t, and those are 850/1900 WCDMA. None of your devices will see 3G here in NA. Europe operates 3G on 1900 and 2100 and a few on 900 WCDMA, Japan and South Korea are on 2100 WCDMA only and NA is on 850/1900, so you need to be really careful of the hardware you purchase for it to work where you want it to and at the speeds you want. Edge comes on the older GSM frequencies and almost all phones have the 4 GSM frequencies, 850-900-1900-1800, but none have all the GSM and all the WCDMA frequencies, could but don't. Most US phones will have 3 WCDMA frequencies, 850-1900-2100. Better to buy an unlocked tilt 2 or sign an agreeement with at&t for a discounted phone.
Good luck.

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

Does the Galaxy Nexus LTE version also support the Penta-Band GSM bands for international travel?
Verizon version = GSM + LTE?
Sorry I'm a noob at Verizon's ways.

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

I always thought that Verizon always had bands for international travel also? I mean not really a big deal. Verizon is the clear winner for coverage nationally and since my work is paying for it, its even sweeter.
Right now I just have a blackberry

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.
