3G ATT (usa)?

not quite sure how to search this so i guess ill ask (or reask) the question.
1. am i able to reflash my Leo to work with USA ATT 3g bands if a rom ever comes out in the future?
2. can someone confirm to me if step #49 of this tips and tricks thread (http://forum.xda-developers.com/showthread.php?t=583638) and that piece of 3G activation software works and can allow my Leo to work with ATT 3g? (i dont think it does)
thanks!

1. Nope. It's all hardware.
2. See above. Nope.
It's all edge, my friend!

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).

do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.

ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still

T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.

this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."

Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.

thats the link

Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?

* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE

Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?

GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)

For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.

An Intresting question regarding the T9193... (Telstra Leo)

Ok, so I am from California and currently living in the UK... So I have one of the T8585 models... now I know that I am going to lose my 3G connection when I go home so now I am thinking of buying one of the Telstra T9193's to work on home networks (AT&T).... but looking a bit further at the specs of the 9193 the bands for 3G are listed as 850/2100... so does this mean that if I travel back to europe with an american sim in the phone I would still be able to have 3G connectivity? If I wait for the T mobile version which I assume will be 850/1900, if I return to Europe I would have the same problem as going back home with the T8585... Seems ridiculous actually, you should be able to get a phone like this that can maintain connectivity regardless of where you travel. I remember this problem when I first moved over to the UK and had to get a Razor, just for the quad band so I could use it on both sides of the pond... Oh well, would really appreciate it if you guys had any thoughts on these assumptions and maybe shed some light

Hi !
Though the question is quite old, the answer is still interesting for anybody planning to travel or intending to buy an overseas model.
I personnaly had to resign on finding an US T-Mobile HD2 because of the 3G bands problems : our local operator decided to use 2100 MHz to cover the capital, but 900 Mhz for the rest of the island, so I was forced to stick to the European model, in order to be connected where I would need it the most, i.e. in the bush.
I could find an interesting website listing a lot of models, and able to compare them, so just have a look by yourself to this one :
http://pdadb.net/index.php?m=pdacomparer&id1=1783&id2=2062&id3=2059&id4=2192&del_id=2062
As you can see, the only differences (apart from the US T-Mobile 1024 MB ROM I'd dream to have and the 2 mm longer bottom border for the different antenna housing, given that the 576 MB RAM are actually present on all models - it's just a question of flashing the appropriate radio ROM) are the UMTS/HSDPA bands frequencies.
European HD2 (T8585) : 2100 and 900 MHz
Australian (Telstra) HD2 (T9193) : 2100 and 850 MHz
US (T-Mobile) HD2 (T9393) : 2100 and 1700 MHz
The 2100 MHz is common to all of them... Too bad a lot of operators choosed to use the other band.
P.S. : There's even another model, the AT&T HD2, featuring 1900 and 850 MHz UMTS bands, the same size as the European model (but featuring the green and red buttons), but having the 1024 MB ROM...

You're the only person to ever mention a 4th model, got a link?

In a former thread I posted the following list of HD2 I found the last two years:
1. T-Mobile US PB81120 (more memory for T-Mobile requirements and for USA specialized radio chipset)
2. European HD2 PB81100 or T8585 (specialized radio chipset for Europe)
3. Asia/Pacific (Telstra) HD2 PB81110 or T9193 (specialized radio chipset for Asia/Pacific)
4. Chinese HD2 T9188 aka Tianxi (with specialized radio chipset for China and design adjustments)
5. Dopod HD2 T8588 (identical to T8585 apart from dopod logo)

Ah I was ignoring the dopod, it was the line "there's even an at&t model" I was querying.
As for the 9188,, does that even count as a hd2? Different codename, different case, slower processor, doesn't mention hd2 anywhere in its details,,,,

Here for the US AT&T 1900/850 MHz HD2 (don't know the series number) :
http://pdadb.net/index.php?m=specs&id=2062&c=htc_hd2_us_htc_leo
Here for the DoPod T8588 2100/900 MHz HD2 (actually identical to the European model) :
http://pdadb.net/index.php?m=specs&id=2386&view=1&c=dopod_hd2_t8588_htc_leo_100

HD2 TMOUS bands are mentioned incorrectly ...
GSM(1900+1800)+UMTS(900+2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
pulled straight from my TMOUS band settings ...

You have a cooked rom installed so you will be presented with the bands from the stock rom that the rom was based on, not what the hardware is set to.

That had crossed my mind but thought it would pull band data direct from hardware.
Bit of glitch, can this band data be corrected ! is it registry based by any hopeful chance ?

could be, and im no longer on winmo and cant remember anything specific.
Id maybe fire up 'cereg editor', load up my registry and do some searches, see if anything turns up.
It doesnt really matter, the correct settings will be used, it wont affect the function of the radio.

Would like it to show correct bands just to refresh my memory of actual hardware bands when choosing options as travel a lot, although never had a connection issue abroad yet !
Will do a search on XDA & my registry & see what comes up.
---------- Post added at 04:48 PM ---------- Previous post was at 04:31 PM ----------
Found them in Registry:
HKEY_LOCAL_MACHINE\Software\OEM\PhoneSetting\BandType
Any one got the default TMOUS key value data from this path for reference ... ??

The choice between the bands may be set in the registry (band 1 / band 2 / auto), but not the frequencies, of course.
They are hardware only. Hence the different models.

So anyone got the standard TMOUS ROM & show me what options are for Bands.
I want my menu to show correct data for each option related to my TMOUS hardware not the data for the 6.5.x custom ROM donor devices hardware.
I more than realize band frequencies are not adjustable via reg keys.
Simple enough for anyone on standard TMOUS rom to look .
Thanks,

T8185= EU, T9193 = AUS, which model is available in Asia?

I'm just a little bit confused. read up on a bunch of posts here that talks about the different models there are right now..
from what i've gathered
US t mobile = pretty much T8185 but with 1gh rom
EU = T8185
AU = t9193 with 850 band frequency coverage
so which version do retailers in asia carry?
thanks all.
cheers.

ok..I want to correct you...in europe the HTC HD2 is T8585

t8585 model

thanks for the help!

Determine Model of Phone?
I just received my HD2 from an internet retailer, and 3g doesn't work with T-mobile US.
In band selection it has 900 and 2100 as UMTS options and no mention of 1700.
How do I determine exactly which model I have in my possession? I'd like to have all the facts before I ***** these guys out and demand a new and correct phone.
I tried to check the radio and rom versions, but I couldn't see way to tell the versions apart.
ROM 2.10.531.1 (82076) WWE
Radio 2.08.50.08_2
Ram size 576mb

If you want a phone that is compatible with TMobile in the US, you need to buy it from... drumroll... TMobile in the US. No one else is compatible on their 3G net.
The TMoUS will have TMobile right across the top of the screen.
The 9193 will have NextG and "T" on the lower third of the back case.
The 8585 will be completely unbranded, as far as I know?

I'm living in Singapore, bought mine from starhub,
The model is T8585 and supports all frequencies [HSPA/WCDMA/GSM/GPRS/EDGE (900/2100/850/900/1800/1900 MHz)] , so it'll work everywhere

You only have 3g on 900 and 2100 with that model, though. All the models have gsm working on all the bands, so you can get regular service everywhere.

Thanks for the info mazzarin,
Somehow 3g started working.... maybe I just needed to leave the house. 3g was showing in the status bar before, but failing to connect. My phone says T-mobile across the top, and the UPC on the box seems to be a US phone; however, under settings-->wireless control-->phone-->Band it still lists UMTS (2100+900 as an option), which doesn't make sense.
Any idea what this means?

The Telstra 850+2100 phones say the same thing. Just ignore it. The bands are determined by the hardware amplifier circuits on the phone anyway. You have the TMOUS HD2, so you are fine. (Other than their tiny network )

The network may be tiny, but 2mb/s down and 1 up is pretty good. Coming from AT&T service, I'm impressed with the speed. Now I can't just leave any major city

k..im confused
here in canada, rogers uses 850/1900 for the 3G
if i get an unbranded T8585 from asia, will it support the 850/1900 for 3G?

yea i know about telstra..but as you may also know..its very expensive..close to $850 canadian
maybe i should be more clear with my question..and that's getting a t8585 from hong kong specifically, or anywhere else in china for that matter..

ahh yea, the price factor. well as already mentioned by zarathustrax the t8585 (same in europe as asia, , same phone, same bands )only does UMTS on 900/2100, so no 3g, edge only i'm afraid.

can i use t mobile htc hd2 in australia

hi every one im thinking about buying a tmous htc hd 2 cause of the 1gb rom 576 mb ram , im just wandering if the phone will work in australia 3g , vodafone , i found out download band for voda is 2100 and upload 900
can some one shed any light on this should i buy the tmous htc hd 2 or t8585
thanks in advance

The TMOUS HD2 is actually the least useful of the three varieties to you (TMOUS, Telstra, European/international) - I use a TMOUS in New Zealand, and the gist of it is that it will work absolutely fine once unlocked, but it has a useless second 3G frequency - you'll only be able to use 2100, since the TMOUS uses 1700 as (I think) rather than the more standard 900.
The Telstra variety has 2100/850, and the European HD2 has 2100/900.
So, if you just want the extra ROM space, go for the TMOUS. But if you want better 3G coverage, it depends whether you want Voda or Telstra as a service provider.

Should a UK HD2 act different on a Canadian Network?

Hi All
I have recently moved to Canada with my UK HTC HD2.
Since moving here I have changed my phone provider to Fido (Rogers Network). Internet seems extremely slow compared to my UK provider.
Someone told me that because I have a UK phone it is not using the correct bands for HSPA and that's why my internet access is so slow. Internet access is extremely fast on Wi-Fi so I know it's not a problem with the ROM etc.
Can anyone give me any ideas if this sounds correct - do I need to sell my UK HTC HD2 and purchase an American one to get over this problem?
Thanks

I think your friend is correct.
Rogers uses 850Mhz and 1900 Mhz, while in the
United Kingdom the bands used are 800Mhz and 1800Mhz (and some 2100Mhz),
Your UK HD2 is of European configuration, and should be able to cope with the Rogers frequencies. (See)
Your phone uses 900 - 2100 for 3G
Rogers provides it at 850 - 1900 , therefore your phone will slow down to GPRS speeds.
Have you tried flashing a new radio ROM?
If so, perhaps you should try another one.
At least in theory you could keep your phone and have mobile broadband.
What your friend is telling is true for dual band phones, however the HD2 is quad band..... Perhaps contact your provider (sometimes the dataplan has not been correctly activated, therefore access to mobile broadband is denied, and you will revert to the low GSM data band)
Otherwise contact HTC.
PS: Sorry for my ****-up

the t8585 (regular hd2) uses 900 and 2100 for 3g.
source
thats why canadian users with cash to splash go for the australian telstra model which uses 850/2100
You will only get GPRS and edge speeds, and no, the american wont get 3g either.

Yep....
I's official, I am cross-eyed, got the correct info, but wrong interpretation.
I stand corrected.

Thanks to both of you for the response .... I'm a little confused though!
So if I bought a T-Mobile USA model - that wouldn't give me 3G on the Rogers network I'm on? I have to buy an Australian Telstra model to get 3G?
Thanks!
*EDIT* ... Oh I think I get it now... I don't need to have the 850 and 1900 bands to use 3G on the Rogers network so long as I have one or the other - correct me if I am wrong please?

yea thats it, and the US hd2 has 1700/2100 which is why that one doesnt get 3g on rogers.

I get ya! Thanks for that.... so is Canada the only country that uses 1900? I'm asking because I now know that I can buy an Australian phone to suit the 850 but is there another country's phone apart from Canada that will use the 1900 band?
also I noticed something in my phone settings....there's an option to change my base band so I have selected 850/1900 GSM but it doesn't seem to have made a great deal of difference even after a reset

that's gsm, (calls, gprs and edge) nothing to do with the umts bands.
put umts bands into google, theres a Wikipedia page tells you what countries and networks use what bands.
