Touch PRO 2 with UMTS 850/2100 MHZ

hi guys,
check this out..
http://personaldigital.com.au/p171/HTC-Touch-PRO-2-T7373-850-Mhz-NEXTG-%21%21-PRO2/buy.html

It has those frequencies selectable out of the box on any version I believe.

no, you are taking about the GSM bands
i was talking about the UMTS/ WCDMA 850/2100
Most versions WORLDWIDE are 900/2100
850 is the AT&T (USA) and Telstra (Australia) 3G Bands

I am under the impression AT&T and Rogers/Fido also use the 1900mhz for downloads. The 850 bands is only the "upload" band.

Yeah, but paying around 400 dollars more for an 850mhz band you must REALLY want it.

Wait a second
I know att uses the 850 and 1900 bands for 3g but I never heard that the 1900 band is for downloading and the 850 band is for uploading. Is this true? Can anyone confirm this 100%?
I was holding off buying the samsung omnia II because it only had the 1900.
Unless I am mistaken, when do you really need to upload anything on a mobile phone?
I hope someone can confirm this asap because then I can get an omnia now instead of waiting for att to release the tp2.

I have a hard time finding a credible source that explains the use of the two separate Bands but I saw it mentioned more then one time.
Anyone got a source with Provider/Bands/Usage, it would be a great tool.
If the bands really serve separate function it's a problem because upload is essential to downloading because you need to tell the server what you want to received hehe.
So 3G band are the following: T-Mo uses 1700/2100, this phone would be a 850/2100, ATT would be 850/1900, Europe would mostly be 900/2100, etc.

at&t has two separate 3G bands; 850 and 1900 mhz. these two bands are independent of each other and each one does upload/download. (this is unlike tmobile which uses 1700 for download and 2100 for upload i believe). So the best thing is to figure out what area you are in; most areas are mixed with 850 and 1900 and some areas are only one or the other. At&t is making a move towards more 850mhz because it is the better penetrating band. I know in south florida it is mostly 850mhz with a little bit of 1900 in miami. Hence why my old Nokia E51 (has 850 and 2100 mhz 3G, like the Telus TP2) worked perfectly down here on 3G. hope this clarifies it

Thanks for the input.
I gotta see what`s the deal with Rogers/Fido in Montreal!

I have a Touch HD from Telstra, i am using it on ATT in CA, it only has 850 for 3g, and it works for both, up and download. My area has mostly 850 and some 1900, I get 3g almost everywhere. works great.

Not worth it. I'm sure the AT&T version will be out within 2 months.
You will end up paying $500-$600 just to have a half-working one up to 2 months early. Its not even unbranded.

That's wrong. According to that page (and others), the Telstra version is a bit over a thousand dollars, not just 400-500 US. And you're right, seems the AT&T version will be out in October.

I mean $500-$600 more than the AT&T version.

your missing the worth
the point is you'll get the original HTC device included with the front facing camera the original keyboard none of the filler apps (that slow down the phone) and the sleeker look with out posibly loosing the straight talk technology. who knows what att will remove to save on cost.

Its already been shown. It loses the front camera and the keyboard arrangement is different. And it has an AT&T logo. Do you really want to pay $500 more just to not have that little logo? The front camera is useless in the U.S. and the keyboard is just different, not worst. Flash the original ROM or any cooked ROM and all your software issues (and lockouts) are gone. Plus with the AT&T version, you have access to super fast replacements if anything were to happen.

Heck, for that price you could possibly buy both the US and the European version, getting coverage basically everywhere in the world

Enabling HSPA: 850/1900 on the Global Version (GSM/CDMA)

Does any body know if it is possible and if so how to enable the HSPA: 850/1900 band on a Global (GSM/CDMA) Version of the TP2.
It already has the HSPA: 2100 enabled... so maybe someone RF inclined could shed some light on this question.
Thanks

I dont believe it has the hardware to do it. It is not a software tweak.
That is why so many people waited for the ATT version to come out. There is an Australian version that works on one of the bands but not both.

Sorry to say that I think you are wrong about the Hardware reason...
Apparently the Pro2 has the chip installed, but it's locked down some how. That info has been floating around from an inside source at Telus. they say it actually has 850/1900/2100 UTMS bands but just got "locked" by Telus.
Also sites like Engaget has long posted some HTC FCC info proving that; http://www.engadget.com/2009/05/20/htc-passes-cdma-gsm-hybrid-touch-pro2-through-the-fcc/
Also The TP2 uses Qualcomm's MSM7600. The specs for that processor allow two major sets of radio interfaces, only one of which supports CDMA 800 and 1900. That major set has two variants that support HSPA: 2100+800 or 2100+1900+850.
So the question is; is there anyone with the proper knowledge that can tell what is onboard the TELUS TP2 and if it has infact the variant that supports the North American frequencies, how do we enable it?
Thanks for posting with FACTS and not Thoughts as this is the only way we will get a valid answer to this question.

Hmm this is definitely an interesting idea. I'd love to have the front facing camera of the Global Version, but I still need 850/1900 UMTS

850/1900 WCDMA on Global version
Gentlemen:
While the chipset has the various frequency capabilities, it is the tuning of the antannae that determines which frequencies are recieveable , ie, turned on, in the various versions. The AT&T version has a different tuning of the antannae than the global versions.
While theoretically possible, the anatanne is part of the main board and must be physically removed and replaced. I have not been able to find a universal antannae that could be resoldered to the board, if one was brave enough to give it a try.
there is software changes to the chipset controller required as well.
I think it is pretty impractical and likely impossible to do outside of have a new board installed with the properly tuned antannae to make it work. I have researched this for some time now, in an attempt to be able to use the EU versions here in NA. I travel internationally a lot, to Asia and EU, and need the 2100 band, so that has been my motivation.
There may be someone else out there who has different information, but this is what I have learned in digging through the available data for the past 3-4 years of various HTC devices and their variants.
Hope this helps,
MWS

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.

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.

ATT Version VS international.

I bought my first american phone (att Galaxy S3) and was kind of disappointed by the development compared to the international version.
This phone is a beast! Thinking about upgrading and since the HW is all the same except for the radio there should be simple compatibility between ROMs except for the radio off course? Any dev that cares to confirm and comment?
Thanks.

I preface this by stating that I'm no dev. That said, it seems to me that devs should be able to separate the ROM from the radio, and convert International ROM's to work with the AT&T version.

Absolutely. There where a lot of droid roms with no radio in the past so that should be no issue now. However there might be something we are missing as I am no dev either. I guess we just have to wait and see after it is released. Sometimes they change small things like audio chip and stuff like that.

While it might seem simple to seperate the RIL and the rest of the firmware, you should take a look in the international Note2 forums and notice the lack of N7105 development. (The 7105 is the international "LTE" version and would actually be more similar to what AT&T is releasing.)
Take care

I did notice that but at the same time it was a lot of nice modders showing there faces.I believe it was a month ago it was released. I think we are going to see more activity soon (hope). However. The international sgs 3 is more similar (CPU) to the note so maybe fewer upgraders from that one to the note. For instance there is no CM yet.

What you'll lose with the international variant (when compared to the AT&T variant):
LTE
"local" warranty service at an at&t store. (Without buying extra warranty packages such as squaretrade, the international version either won't have any warranty at all, or will require shipping the phone to the place of purchase who will then ship it overseas for actual warranty service.)
Possibly some network/radio "tweaks" to supposedly work better with AT&T towers. (AT&T will tell you this matters, but my own experience has been that AT&T locked devices seem to work WORSE on AT&T towers when compared to generic international radio settings.)
Certain extra bloatware that AT&T preloads on the phone that might not be available or functional on non-AT&T devices. Examples of things that some might consider useful: visual voicemail (supposedly not available on non-LTE devices - I use google voice instead); whatever AT&T does to allow their phones to connect to AT&T wifi hotspots without the need to pre-authenticate or accept extra terms and conditions on each connect.
...In my own opinion, I think the LTE and warranty service items are the only significant things.
For many, LTE might not be that big of a deal. Perhaps there isn't any LTE service in their area or their usage patterns are such that the faster speeds aren't significant. Actually, depending on how you use the phone's data, LTE can actually be a bad thing. An example would be someone who mostly just uses their device for email. Fetching and sending email is usually done in the background, so the data speed doesn't matter - but that background data using LTE will suck down a battery much faster than the same background data using EDGE/UMTS/HSPA.
However, LTE can be great if you use a lot of data for web browsing, tethering, or things like pinterest that use a lot of data interactively (and you are in an area with LTE service)
The warranty issue is only a loss if you get a phone that requires service covered by the warranty. While this is rare, it's not unheard of.
Perhaps the screen goes nuts after you've had the phone for 2 months. If you bought the phone from AT&T, you can get a replacement in a day or two (at no cost to you.) If you bought an international version from (for example) expansys, you'd have to ship the phone to expansys-usa, they'd ship it to Expansys Europe, who would then ship it to Samsung for service. After a few days or weeks, samsung would send the supposedly fixed phone back to expansys europe who'd send it to expansys-usa who would send it to you.
Some US-based retailers of the international phone won't even provide that type of warranty service - in that case, you'd basically have NO warranty at all. (This is the case with many of the amazon-based places that sell the n7100.)
... on the other hand, there are many negatives to the AT&T device when compared to the international (and those have been discussed many times over, so I won't list them all here.)

N7105?
ANy chance someone could net out the differences between the soon to be release ATT / LTE version and the International N7105 (LTE & H) versions? Like, will the ATT version be able to connect to all:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 800 / 1800 / 2600
like international N7105 version? Seems if it does not, and the N7105 works on ATT it would be best to avoid bloat and issue by obtaining the N7105.

Getting the 7105 for use on at&t would be a waste of money. The ONLY note2 that will work on at&t lte bands will be the 317. EU lte bands are different from US lte bands.

Avoiding the bloat is easy enough to do yourself with a program like titanium. Or you just install a custom rom. HW and support/development are the main things. And in this case it seems to be advantage to att for once in the HW department (minus FM radio that I personally don't even care about) . But from my limited lack of US dev. The international support is far superior atleast in my galaxy S3 experience. Amazing if the development can run simultaneously on att and International. That is a win!

At&t has a warranty. If anything happens to the n7100 your screwed.

[Q] HELP! International [D855] LTE Issue!

Okay, I'm kinda freaking out. I bought the international factory unlocked LG G3 thinking it was the best way to go, more universal, higher specs, save money. I used Net10 with AT&T's towers for my last phone (which was 3G only), so I bought a new certified 4G LTE SIM, popped it in and activated... I was in love with this new phone until I realized something: I was paying for LTE, but I was only getting HSPA(+) speeds even though the coverage map for all the major carriers cover my area without a doubt. So I started digging a bit and found that although this phone supports LTE, the bands it supports do not coincide with the bands of AT&T, T-Mobile, or really any carrier in the US for that matter.
From Phone Arena: {LTE 700 / 800 / 900 / 1800 / 2100 / 2300 / 2600 - D855} < supported | Wikipedia of all the LTE carriers :
So needless to say, I am frustrated. Nearly $600 on an amazing phone with the downfall of corporate B.S. So here I am, crawling on my knees to the most renowned Android forum in the galaxy for a solution (probably involving some hackage). I have tired accessing the typical Mobile Networks page in Settings, all that shows up is "GSM/WCDMA", "GSM ONLY", and "WCDMA ONLY". I have also accessed the hidden menu by typing "3845#*855#. This doesn't do squat. It gives the option to change the band, and returns "SUCCESS", but it doesn't seem to take hold of any change. My phone is rooted, and I believe the bootloader is unlocked. Help me out here guys; you are my only hope. It appears what needs to happen is I need to enable band 4 (1700MHz) on this thing without it blowing up. If anyone has the American firmware, that may be a good place to start.
Thanks in advance

I just did the same thing. Oops. Assumptions, man.
Anyway, I know this is an old thread, but solutions are still appreciated. At the moment, I'm looking at this little gem, but would like to avoid it if I can. http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
