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,

I noticed an unlocked US 3G Diamond at Best Buy today. I'm sure this has been asked before, but I can't seem to find the answer.
What makes the US version work on AT&T with 3G over the imported version? I have not seen a radio upgrade that allows it yet. The handsets actually looked quite similar with the exception of the back and battery.
I'm just curious whether to pick up the new one in order to get 3G service, or is there a radio update expected?
Thanks to anyone that can shed some light on it for me.
I have a US 3G version and the freq. that at&t uses here has been enabled.

Sure, it would be the 850 and 1900 Bands. But there are Quad-Band radios available for the EU Diamond. I wonder if it's a question about the device not having specific hardware or just being able to enable those bands to work properly.
Sorry for my english
he American Diamond has quad band in GSM and only two band in HSDPA, The people here says that is a har problem not the radio, the people put the american radio (08) in European version and dont work.
The American version came with the 1340 mh battery and without the front camera. Carlos

I have a Touch Diamond I bought last week from new Egg, just like the ones from best buy. For some reason, I can pick up the 3G signal and it will hold on to it for just a second, then x..{disconnects}..then immediatly picks up Edge and then Hsdpa?
I get 25% Edge and 75% Hdspa. I guess if you read the box, it says it picks up a 3.5G internet Broadband Connection....Anything over 3.5mbps is Hsdpa.

I notcied that the US version had the 1350 mAh battery instead of the 900 mAh like the EU version. Was there any documentation on why they did this? Has anyone checked if putting the smaller battery and slimmer back on the US version causes any problems?
I also find it odd that HTC briefly listed the Diamond as a Quad-Band phone on their website, and have since changed it back to a Tri-Band phone.
I still have hope that our European Diamond will work with US 3G with somefirm ware flash or something
No, it will not.

I am in Canada and one of our carriers Telus just released the TouchPro 2
telus is a CDMA carrier, however, released the device as a world phone, quad band GSM and UMTS 2100 3G.
I am new to the GSM world and would like to understand better.
Telus and another carrier, bell mobility are building a 3G+ network that they plan to fire up later this year, the CDMA network will stay for a while and HSPA+ will be an overlay network with no GSM support.
Telus and bell plan to use UMTS 850/1900 bands.
When a company like HTC makes a phone, are the UMTS radio's hardware or software?
Is it possible for a OEM working with a carrier to hide UMTS 850/1900 bands or install 850/1900 bands in a new ROM update, say Windows 6.5 ROM?
It does not make sense to me for OEM's to make multiple versions of same phone, I understand each carrier has cosmetic outer requests, I am thinking of the core inside build.
It would be nice to have both networks in case the initial network build out for HSPA+ has issues.
Help!!
UMTS Radio is hadrware.
GSM/WCDMA(or UMTS, if you will) basebands are all hardware as the last poster noted. However, at the request of a carrier, one of the radios in a dual mode CDMA/GSM device can be disabled(as is the case with the dual mode CDMA/GSM version of the Touch Pro2 headed to Sprint here in the US). It is also [theoretically] possible to re-enable the GSM radio in one of the dual mode versions of the Touch Pro2.
On a side note, I wish the CDMA carriers here in the US would transition to GSM technology. I know Verizon will be conducting LTE trials late this year and early next year so that's a plus. It would be nice to transition to LTE, as well, or at least HSPA+....
EDIT: Actually, many OEMs make multiple versions of the same model device. The Touch Pro2 has numerous variants for each carrier which will sell it.
Well, in this case it's a different build from other Pro2's as it has cdma and therefore a different processor.
As for what it is truly capable of I don't know. Carriers have blocked out hardware functionality through software in the past (i.e. certain famous cases of phones with GPS having to wait a long time before a ROM that would let them take advantage of the GPS).
So maybe it's possible. I don't know if it is in this specific case, someone more familiar with the specific hardware and stuff will probably have to weigh in for a definite conclusion.
Hope so though...
UMTS Bands
Wow,
Thank You for the prompt replies.
I think the Telus TouchPro 2 is the same build as Sprint with Telus customization.
I understand that the hardware radio must be present for UMTS 850/1900 to work.
I am not too concerned about the GSM radio(s), just the UMTS radio(s).
According to the spec, it only has 2100 UMTS band
If Telus and likely Sprint have disabled the radio, is it possible to find out if indead the radio would support UMTS 850/1900 and could a cooked ROM enable those above bands?
seems I responded more or less at the same time as jaekidd
anyways...
according to the msm7600 spec sheet it can have the following umts combinations:
2100
1900+850
2100+800
2100+1700+800
2100+1900+850
Now I personally have no idea how one could check to see what options the installed hardware has and whether they are blocking something.
no idea if a new ROM could unlock those frequencies should they be present or how easy it would be to make a ROM to unlock them (they might need a ROM for a device with those features unlocked on that chipset from which to rip the necessary files/drivers for all I know)
And for the record, I think it might be more appropriate to say that the Sprint version is the Telus version with Sprint custommization (after all, the Telus version has come out first), rather than the other way around
and for the record the msm7200 specs sheet says it is capable of the same combinations but personally I can only remember dual band hspa in HTC's phones (the msm7200a sheet doesn't mention the combinations, just the individual bands)

HTC FUZE (AT&T's Touch Pro) has 850, 1900, and 2100 and I assume AT&T's Touch Pro 2 will, too.
Didn't know that, just the question remians of when AT&T will get theirs out to market.
Hello
I have HTC Touch Pro2 international version, so it doesn't work with 3G in USA.
Is there any way to make it work?
P.S. I have AT&T SIM card.
Thanks
This question has been asked and answered several times already, but the short answer is no. ATT uses different bands for 3G than in Europe and Asia so the international version won't get 3G speeds. Unfortunately you are stuck with Edge speeds.
Thanks for replying
I noticed that old PPCs (HTC, Xperia, ...) support all HSDPA frequencies even international versions, but the new ones don't.
Why is that?

It really just depends on the specific phone. The US versions tend to support both US and International 3G versions, but usually not the other way around unfortunately. Things really got wacky when T-Mobile USA decided to rollout their 3G on an entirely different frequency (1700/2100) than ATT (850/1900), whereas the rest of the world uses straight 2100. (Note TMO USA uses one frequency for up and the other for down, so an international phone with just 2100 won't get full 3G on TMO USA either).
Usually manufacturers have slightly different versions of the phone for different bands (like the Xperia X1 has two different revs for different parts of the world).
If a manufacturer wanted to make an UBER-GSM phone, they would have to put a Quad-Band GSM chip and also support 850/1700/1900/2100 (Quad-band 3G), which I don't believe currently exists (yet) and may never...
A question came up on the us forum for Defy about the different software builds until finally a Moto-mod came in with this. It's intriguing in that apparently the Defy has all band capability, but the software build limits the choice. Here's the quote:
"Each Blur Version for the Defy is all Carrier and Regional Specific like for instance For US T-Mobile Customers its 3.6.19.0 however for UK T-Mobile Users I think the latest version is 2.51 Other parts of europe are using 2.34 without MotoBlur and so on and so fourth, the main difference is Carrier installed apps and the confusing part, from what i've expierenced with the phone, Its the first phone i've ever seen with a software controlled universal radio supporting all bands, however its software tells it which band to use, for instance if you 2.21 and 2.51 UK versions are using UMTS 900/2100 where US's 3.6.190 is using AWS 1700/2100. there are ways if you look to obtain version 2.51.1 however this isn't the place to look on instructions on how to do it because its against the forum rules, is unsupported and with 2.51 if for whatever reason you wanted to downgrade you couldn't unfortunatly."
WHAT.
Software defined radio?
If this is for real the hackers SHOULD REALLY HAVE A FIELD DAY with this phone.
It's a shame they're too busy with the Samsungs and HTCs of the world..
There's quite a difference between true software defined radio (most radios these days are sort of there, as they are most commonly some embedded chip with custom firmware but nothing like a Linux kernel) and being able to switch frequencies to be used

I'm not an expert, but the basic thrust of this was that all Defy phones are identical and capable of all frequencies, but the firmware defines which can be used. Therefore it seems -- to this novice mind -- that change the firmware change the phone.
The other, related issue is the frustration of some Euro phone owners who really know nothing about differences in 3G frequencies. buy a phone and presume they can use them in the US (as one can with an iPhone). Those of us who prowl these forums are basically smart enough to know that before you buy a phone we have to be sure we can actually use it -- but 90% of buyers buy a phone presuming they can.
Okay well can someone on the forum test this out? You'd need the ability to try and access both sets of frequencies.
Example: You're in Australia and you have a Defy from Telstra which you've also unlocked. Your stock firmware supports 850/AWS/2100. You should be able to get an 850 MHz signal from Telstra's NextG network. Now, if you put in an Optus SIM and visit an area with 900 MHz 3G coverage but not 2100, you'll find the phone drops to EDGE or gets no signal.
So at this point, take a nandroid backup, and flash a 900/2100 firmware or replace the radio files with ones from such a firmware. Now repeat the same test... does it successfully register on Optus at 900 MHz?

Radio issues...
Strictly on the band issue, I don't think they are that apart. A good radio would be able to handle it without being full SDR.
I agree partly on the point that these radios are somehow SDR for they do change the frequencie ranges by changing firmware.
A full SDR would be able to change even to CDMA or something else, not only the band!
If you want to challenge someone for doing something about it, ask for a full tri-band version of the Defy radio! (That I would ask for too!)
I intend to use my Defy originally 850/1900 over a 2100 network.
Well that's is my humble guess.

Interesting, as if you go into the INFO menu and select "set preferred network type" one choice (which it will not allow) is CDMA. But it's there.
Which version of the Defy is UMTS 850/1900? I thought there was only 850/1700/2100 and 900/2100.
Also, pretty much all Androids have CDMA as a listed option, not because they're compatible, but because it's a testing menu that was designed to be applicable to a wide variety of phones.

Hi all,
I've been a very happy user of the Desire Eye, and believe it to be a great all round performer. For me, there does seem to be 2 omissions on the phone that stop it from being the total package. One is 802.11ac wifi (which, to be honest, isn't really required on a phone, right?) and the other is more support for more LTE bands.
I've got the asian version, so I believe the LTE support on my handset to be: 700 / 900 / 1800 / 2100 / 2600 (FDD).
My carrier here in Australia uses 1800 mainly, but is bringing in 850LTE too.
I'd love to be able to expand the band selection to cover this, as well as other bands for when I travel.
It appears some people have figured out ways to do this on some handsets - http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I'm not quite savvy enough to attempt this at present (root, ROM, fine, but editing NV, never tried), but was wondering if some of the more technical guys on this board may have some thoughts around this?

I am sorry if this question makes no sense, but is LTE unlocking same as SIM unlock?
Do I enable use of other GSM providers or is this speed / bandwith related only?
