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.

HTC HD2 3G Not Detected!!!!!

Hello if someone could help me with my 3G connection inquiry, I would greatly appreciate it.
I bought this phone unlocked from Hong Kong and brought it back to Canada. But the 3G connection through Rogers won't work. I am able to connect to edge (When i pop in my sisters sim card which has a data plan, as my sim card currently does not have a data plan).
I talked to Rogers and they said that everything is compatable (After mentioning the phone frequencies and speed capabilities) and that the only reason 3G isnt working is that I have not configured my phone properly for 3G and at this moment it is configured for 2G (Edge).
I then contacted HTC and they said the reason was because "for the Rogers network, their 3G signal is operated on the 850/1900 MHZ band and the Touch HD2 operates on the 900/2100 MHZ band." Could this be the reason? Will i never taste the pleasures of a 3G connection?
PLEASE HELP!!

since you have bought it in hongkong most probably you have the asian version. It comes with 900/2100 MHZ bands and as you mentioned ROger needs 850/1900 frequency.
You could also get Telstra version from Australia and unlock it as it has 850/1900 frquency so that you could get 3g. But not possible on the one you already have.

Yea its the frequencies. When I take my phones abroad, I always check what frequencies the country has. If the frequencies don't match, the phone won't work in terms of placing calls, 3G etc.

is there a way to unlock ?

There is no software that can get around this "problem"
It is purely a hardware limitation.

perhaps with flashing radio but i'm not shure

Does Tmobile (US) HD2 work in China?

Hi, all,
I travel between China and US often. I am thinking about buying TMO(US) HD2, since it is a lot cheaper than anywhere else I have seen. Also, It comes with other goodies and full warranty. My concern is that will the phone work in China under 3G? I know there is iPhone in China (China Unicom). I think it operates on AT&T 3G (WCDMA). China Mobile uses TD-SCDMA. 3G on that is out of the question. If I don't get 3G, I guess EDGE is ok, I don't even think I get that speed on China Mobile. Don't really want to put close to $500 for an experiment.
Any answers would be greatly appreciated...
Perry

The USA T Mobile radio uses quad band (850/900/1800/1900) for the GSM freq. The 3G freq is 1700/2100.
China GSM uses 900/1800 for GSM and 3G. So, you will get EDGE speed but not 3G.
On a different note, you would be able to get 3G in Korea and Japan because they use 2100. You have to make sure that Auto is selected for you Network Type and Band Freq on the Band page for that to happen.

I'm thinking about getting an HD2 to use here in Japan.
It feels like a gamble. I have a SoftBank X01T and I've been using custom English roms. (I know the AP and password) (The Sim is with SoftBank).
I'm hoping it's possible to just get an HD2, pop the sim card in - set the AP and password as usual and it should be ok?
Any thoughts please.
Plus anything to backup the 3G working in Japan.
Thanks if you can advise.

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.

[Q] European DZ in USA, 3G?

Hi everyone, i'll be going to USA, NYC for a week for the first time, and i'm wondering if i can get on 3G with my European Desire Z with a sim card from T-Mobile or AT&T, I want to be able to use gMaps to find all places i want to see and do some emailing, uploading photos etc.
also, which one should i choose (T-Mobile or AT&T)? i've read about the "goPhone" and "pay as you go" from AT&T but also the "Pay as you go data" plan from T-Mobile. researching this only gives me headace haha would be very happy if anyone could help me out with this (and where i get these prepaid sim cards, couldn't find that out anywhere either!).
but my main question is, as i said, will i be able to use 3G on my European DZ in the US?
i'm sorry if this is in the wrong forum, i really am. if it is, can a mod please move it for me?

I went to Houston in March. I have an unlocked Desire Z & bought a SIMPLE Mobile SIM card a week before I left (http://www.ecrater.co.uk/p/7077857/simple-mobile-gsm-unlimited-sim) then I registered on the SIMPLE Mobile website & bought the $60 tarrif (unlimited domestic calls, international & local texts, and more importantly unlimited data) (http://www.mysimplemobile.com/Simple-Mobile-Plan.aspx) I then popped it in to my Desire Z upon landing in Atlanta & put my existing T-Mobile UK SIM card in my wallet until I landed back in the UK. Phonecalls & texts worked instantly when I turned my phone on. However 3G was a bit trickier. I Google (using free Wi-Fi) & found the SIMPLE Mobile 3G settings I needed:
Press the menu.
Tap Settings.
Tap Wireless Controls or Wireless & Networks.
Tap Mobile Networks.
Check that: "Data Roaming" and "Use Only 2G Networks" are both unchecked. ETap Access Point Names. Press the menu button.
Select New APN. Name: Simple Mobile APN: simple proxy: 216.155.165.050 Port: 8080 Username: [empty]

and it was perfect for the time I was out there. I was tethering a whole household at one point, tethering my girlfriend's UK Blackberry (with UK SIM) while driving too. I would recommend it!

Thanks for the tip!
I've never heard of "SIMPLE" before, so i'd like others to post their alternatives, so if anyone else have done this before and would like to share what they used (and how), I would be very happy.
If noone else comes up with an cheaper / better way, ill use it =)
E; saw that you need to put in zip-code on the tarrif page, i assume i type in my home zip-code (which doesn't work for me)?

Someone correct me if I am wrong, but SIMPLE mobile is owned by T-Mobile here in the US. They utilize the same bands/frequencies as Tmobile but operate as a Pre-Pay cell phone provider... No contracts required.

well you gotta verify what 3g bands uses your european DZ, from what i know there a 850/1900 mhz version which would perfectly run 3g with at&t, and theres also a 900/2100 mhz version which i think it could run t-mobile's 3g, but you need to verify which is your version before buying a sim card, if not youll be stuck with edge (2G)
im almost sure your version is the 900/2100 one tho

Yeah T-Mobile, but I don't think they are owned by them, I think they're just a mobile virtual network operator like GiffGaf & Tesco do to o2 in the UK.
I was all over Houston, from The Woodlands to Galveston & worked perfectly. Also in New York & Atlanta. However, it is (by UK standards) a rather limited network http://www.mysimplemobile.com/Simple-Mobile-Coverage.aspx

I think i read somewhere that the european dz would work all over the world sine it had support to all bands unlike the us one...
Anyhow how do i verify it?
Btw; what should i put as zipcode on the tarif page? Since its doesn't work with my Swedish zipcode (haha lol)

There is no phone that works for everything, everywhere. Where are you planning to use the phone? You'll have to be more specific, different countries use different bands for different things.
The European DZ has the following compatibility: HSPA/WCDMA: 900/2100 MHz GSM: 850/900/1800/1900
You should check those against the bands used by the carriers in the country you are travelling to. http://www.worldtimezone.com/gsm.html
The Euro DZ has the correct GSM bands to work for voice and EDGE data in most parts of the world. But bands used for 3G vary greatly by country and carrier. If you are going to the US, you won't have 3G on any carrier. The only GSM carriers in the US are AT&T and T-Mobile. AT&T uses the WCDMA 850/1900 band for 3G. T-Mobile uses WCDMA 1700/2100.

so if i have 900/1800 in sweden(like the rest of the world, expt america), does that mean i can't get 3G in the US? or what are you trying to say...? confused

The 3G band compatibility of the Euro DZ (same model all across Europe, AFAIK) is WCDMA: 900/2100 MHz
This doesn't match either of the two US GSM carriers, AT&T (850/1900 MHz) and T-Mobile (1700/2100 MHz). So no, you cannot get 3G in the US with that phone.
Also, if you were going to ask, the 2100 MHz band (known as Band I) used in Europe is not the same as the 1700/2100 MHz (known as Band IV) used by T-Mobile. T-Mobile uses 1700 for upload, and 2100 for download, so you need both in order to have 3G on their network.
I only supplied the website to look up the country, in case you want to travel to other countries beside the US. The spec of the phone is what is important to look at, and whether that matches the country you are traveling to. Also, you are not looking at the chart correctly. 900/1800 for Sweden is for 2G/Voice. Sweden and most of Europe uses 2100 MHz for 3G (see the green column).

i may not know much about this; but, if you say that you can't get 3G in the US with a DZ; how come others says they can, and have had (such as salemfox, who suggested "SIMPLE" sim card)?

If you're reffering to "Simple Mobile", then no it still won't work, as they piggyback T-Mobile's network. Sadly there is no gsm carrier in the us that you could get 3g from, edge should still work though
