Use in Japan?

Can I use the european HD2 in Japan?
They are the same, arent they?!
I ask, because last time I had a UMTS phone with me and I heard only UMTS will work. Data spec doesnt mention UMTS anymore.
Please forgive me my "no no knowlege" in bandwith..
If anything expect GSM will work, I am safe
Didnt look what kind of network it used last time..

Oh come on..
Somebody have to know it
Cant think of the possibility that this question is too hard for xda pros

I have used my HD2 in Tokyo with no problems. It is a quad band on the GSM freq 850/900/1800/1900, but the 3G (HSDPA) is on the 900/2100 freq. 2100 is what Japan and Korea use, and I have used it in both places.

Are all HD2 around the world 900/2100? It seems USA isn't using this band for 3G, or is it?
Do you get HSDPA in Japan?

No, USA doesn't use 900/2100.
See Here

but there's no way to get JP support or input on HD2

T-mobile's US HD2 works on 2100 MHz 3G in Europe?

Hi,
The official specs of T-mobile's HD2 says that the supported 3G bands are: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Does it mean it will work on European 2100 MHz 3G too? Nexus one does so I suspect HD2 could too but as far as I could digg nobody had a straight answer to this question yet.
-AlefSin

actually i asked HTC CS before, and the answer is NO!
european countries WCDMA frequencies are the same with ASIAN countries. So no chance for European countries either.

hmmm I don't know JohnQ. In your attached email HTC is saying China's frequencies are different from the rest of the world so how do you say it's the same as Europe? I don't know much about 3G network in China though.

Just a few weeks back it was annoounced that the US operators had all signed up to migrating to the rest of the wold's GSM standards!
So in time we will all be singing from the same hymn sheet!

Accoridng to Wikipedia, while 3G in China is using the same frequencies as Europe in UMTS-I band, the air interface is different (TD-SCDMA vs TD-CDMA).
(sorry, cannot link to the docs since as junior member cannot embed links yet).

Wow, that's... odd! It seems US operators cannot even agree whinin US and now they all want to use the rest of world's standards! That's so un-american!

At&T, rogers, etc are all using european 3G frequencies, which is why you can use device from europe on their networks.
T-mobile US uses 1700 & 2100 (one for up stream, one for downstream) which is why it won't work on at&t etc or european frequencies.
The t-mobile 3G phones use both 1700 and 2100 at the same time; and they cant use 2100 seperately on other networks.

erm att uses 850/1900,and very few operators use the same,none in Europe use these bands

I've tested mine on a 3G only network (2100mhz) and it works fine. What I mean by "only" is that the Digi Mobil in Romania works only on 2100Mhz.
I hope it helps!

I did, check post #5

Well, it seems the answer is negative. I asked HTC:
Hi, I'm very excited about HTC HD2 on T-Mobile USA. However there is a cruicial question taht I could not find an answer for yet: Should I get this phone, when I travel to Europe, can I use 3G? The specs say this phone will support AWS/2100 MHz UMTS. Since the 2100 MHz is the dominant frequency for western european 3G networks, does it mean this phone would work on their 3G networks? Nobody at T-mobile's support could answer me so I hope you could solve this mystery.

And they answered:
Thank you for contacting HTC Technical Assistance Center. I understand the importance in researching a phone before you purchase it. This is a unusual situation and one T-mobile may not have been experienced with. For T-mobiles network the phone will be using the 1700 and 2100 bands. Although the 2100 band is common world wide. allowing the phone to pick up the edge network. T-mobile uses the 1700 for there 3G services. This band as far as we are aware is only used by T-mobile when it comes to major carriers world wide. More then likely the phone would not be able to pick up 3g if taken over seas.
However. T-mobile dose have a few branches in Europe. You may wish to check with them to see what bands they use for 3G, and if they have had any conflicts with American phones.

But T-mobile's HD2 is not out yet! Are you sure you didn't test European HD2?

OK things are starting to get weird. I received a negative answer from HTC's customer support but then I found USA T-mobile G1 users that reported their phones were working on 2100 MHz 3G in Europe (G1 like US T-mobile version of HD2 only supports 1700/2100 MHz 3G). I need to buy a phone and these contradictory reports leave me confused

Here is what T-mobile says in the specs sheet of the new HD2:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

Isn't it interesting that 2100 Mhz is listed both separately and in with combintaion with 1700 Mhz?

nice email address you have in that picture John

I tested my unlocked TMOUS HD2 in Sweden using 3's network and worked like a charm in 3G

Bit of a bump here as I'm trying to use my unlocked US T-Mobile HD2 with Orange in France and I can't do better than Edge (it went down to GPRS at one point...). I guess it could come down to spotty reception but I do get 3G speeds in my current location with an iPhone 3GS so I'm not so sure...
I'm using the AmericanAndroid ROM, maybe that's why my speed is throttled ;-)

I am using HD2 T-mobile in Serbia and i have no problem with conection or data speed.
I was on vacation and i didnt use Wifi ,and i used the phone all the time on 3G - the 3G network is incredibly fast, I even think that it is twice as fast as the EU HD2, which I used before..

Thanks, will check again then, maybe bad reception then!

Will unlocked T-Mobile HTC HD2 work in Russia?

I bought this phone in the US in T-Mobile, and I'm going to unlock it soon.
On the specs page it says
Technology GSM: 850/900/1800/1900 MHz
On Russian page it also says:
GSM: 850/900/1800/1900 MГц
So the frequencies are the same.
Will I be able to use it?

if you have a provider which is using GSM and any of the frequencies that the phone supports then there should be no problem at all.

Ok, thanks, I'll try to see what frequenices my provider (Megafon, Russia) supports

I used my old Omnia (which has the same quad bands) in Russia on the MTS network. It worked great.

Great! Thank you

The phone will certainly work, but I doubt you'll be able to use 3G anywhere outside the US, because T-Mobile US uses non standard frequencies.

I'm not even sure there's 3G in my home town in Russia. We're using GSM.

difference between "a" and "i"

What is the difference between the two and can you make an "a" an "i"?

the differences are the 3g frequencies that they support
i forgot the exact bands but i know that the x10a supports us atnt, rogers canada, and telstra australia 3g bands. the x10i supports asia and european 3g bands

The difference is pronouncation. Also a is the first letter in the alphabet while i is the 9th. I don't think you can make i into a and vice versa.
PS. You can make [email protected] and vice versa but it causes SEUS problems.

x10i and x10a both have the same GSM network frequency as 850/900/1800/1900, or you can call as as Edge network as well. As for the 3G frequency or UMTS bandwidth, here is the difference:
x10i
UMTS: 900/1700/2100 MHz
it will support Asia / Europe / and T-Mobile USA 3G network.
X10a
UMTS: 800/850/1900/2100 MHz
like dorifuto.boi said, it will support AT&T US, Roger Canada, Teltra Australia. It also support Japanese Do-co-mo 3G network as well.
You may wanna check with your current service provider and ask them which UMTS bandwidth they fall into the above category. Again, this is for GSM network only. If you are using Sprint, Verizon, etc they are in differenet as they are in CDMA network.

To further add to your comments
SE uses the a or I for country variants
A - America's (Canada, US & Latin America) Support these bands
I - International (Europe, Asia, Middle east etc) support these bands

thanks for the info. I received and "a" as a gift, but am not able to get on tmobile3g. Only getting edge, but it runs fine.

Bell and Telus have 3G (only) networks in Canada in these bands

By the way... it is technically possible to build a phone that works on all the 3G bands, so that it would not be required an "a" and an "i" version?

the Nokia n8 is like that. 5 band 3g. but the x10 is not

Yes it is - for some weird reason t-mobile was included in the international version, and AT&T was on the American version... But the facts is, that both versions have 2100 MHz 3G which is the most used 3G band worldwide... As I see it, you will just have to go into a secret menu and then check off some other boxes, and then it should be able to use the other 3G bands!
I'll post an image...
Uploaded with ImageShack.us

just because they both have 2100 doesn't mean ATT and t-mobile are using them. personally they should have made 1 model with quad band 3g. better for everyone.

International legend on rogers 3g not working?

Hey everyone i was just wondering if it's possible for me to get 3g working on my legend. It is an international legend and I am on rogers canada network. Any help whatsoever would be greatly appreciated.

I don't think it will work. The international version uses a different band (900/2100) I believe.

Thanks for the reply... the back of the box says this:
Network - HSPA/WCDMA (900/2100 MHz)
GSM/GPRS/EDGE (850/900/1800/1900 MHz) Which is what i thought rogers was.

Rogers GSM network operates on the frequencies of 850/1900 MHz so your 3g should work. Are you running stock rom or a custom rom? Do you know if your phone is rooted? If it's rooted and or you are running a custom rom then make sure your are running the last radio for your device..

Rogers uses 850/1900 HSPA bands not 900/2100 HSPA bands.
You will only get EDGE data.

Hmm that's a shame... would you happen to know if it could be used on any other networks with 3g? like wind?

WIND uses 1700 AWS frequency, no providers in Canada use those two frequencies (and god knows why NCIX and other stores are selling the European version to Canadians.) You should really read up on these things before buying a phone.

yeah thanks... i was never told it was an international phone.
