Hello everyone! I'm wondering will this device work with AT&T service since it's just a triband phone, and, afaik, AT&T uses 850MHz as their primary frequency for GSM calls (depends on location) in NYC area.
Coverage maps are here:
http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml
Specifically the 1900Mhz map is here and you can zoom in to your area and see: http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=be
[You can probably also find them some place on the AT&T website.]
Be aware tho that the diamond only does 3G at 900/2100, but AT&T use 850/1900. That means you won't be able to use 3G capabilities on AT&T anywhere.
I would either wait for the american version, or buy the 2G one they're selling in india for ~200$ less.
Thanks, man! Maybe i'll look at T-Mobile plans, looks like device will work with them
Well looking at the page it looks like T-Mobile have even less 1900 coverage (GSM). I don't know their current 3G situation, but they will be/are using 1700Mhz for 3G, which the diamond can't handle either
So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!

Sorry if this is old news, but i just realized it =)
this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...
you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...
That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

AWS?? well the tier 2 tech did say it...i dont know if he was just talking out of his ass or not...but we'll see in the coming weeks...ill try to get tmobile rep on the phone again to ask them how i can get it...or if i can, even though its supported..

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.
If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

Do you know who this user is? maybe i can PM him and get some details...i knew i wasn't going to get 3G with the diamond, but after talking to the rep. i kind of want to look into it more since there may be a possibility.

Honestly I'm gonna go ahead and call BS on him for that, I've never heard of anyone getting T-Mobile 3G and I know quite a few people with the Diamond/Raphael on T-Mobile in 3G areas.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

Hey guys i just recently bought a HTC Touch Diamond unlocked US version and was wondering is there a way i can get the 3G to work? i know the T-Mobile's 3G network is still under construction but the new HTC Dream seems to have access to the 3G with T-Mobile. I heard T-mobile uses the 1700mhz and 2100mhz 3G bands, And that Touch Diamond does not support the 1700 mhz band???
The U.S. 3G Diamond will definitely not play nice with T-Mobile's 3G network, and there's really no way around it because of the hardware it has. Sorry. The Dream/G1 was designed specifically for T-Mobile, so it supports T-Mobile's 1700 3G band, natch.
Picked up my HD7 from the local T-Mobile Store, acquired my unlock code, applied successfully and was up and running (Exchange and all) within 30 minutes on AT&T.

Why do you want to spend so much of money and use it on edge only network ?
why do you want to ruin his experience since apparently he hasn't noticed yet ...

Course they said that. They want the money from the contract/upgrade. Call up corporate and let them know the store would not sell you a phone. There are no restrictions on phones being sold outright, but sometimes, because these stores are not corporate stores, they can enforce their own rules, but reporting them can sometimes make them change their mind.

how SLOW is edge? Is like like a very bad wifi connection? Hehehe... No really, I want to know.
No smartphone is worth the pain of Edge!
I don't know about at&t, but with t-mobile, edge is like not having an internet connection. About 100 kbps and alot of auto updates time out.
Does AT&T 3G require a special frequency that isn't covered by Quad Band? Or is it that T-Mobile 3G has a special, non Quad Band frequency?

there are two band sets for gsm phones, GPRS/EDGE and UMTS:3G/3G+/3.5G/HSDPA/HUDPA (sometimes these abbreviations are used individually to denote 3G service. This is not correct as they all mean a different type of 3G, the most generic term is UMTS).
Sometimes HTC phones have different band sets for different countries.
HTC HD7 Europe:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz
HTC HD7 T-mobile USA Version:
* UMTS 2100MHz AWS1700/2100MHz
* GSM/GPRS/EDGE 850/900/1800/1900MHz
For GSM there is no issue, 850 & 1900 are USA, 900 & 1900 are EU, but all the phones cover everything:
http://www.worldtimezone.com/gsm.html
In the USA, UMTS 3G for tmobile is on AWS 1700/2100 only
In the USA other providers use 850 with some using 1900
For example, the HTC Surround on AT&T uses:
* UMTS 2100/1900/850
* GSM GPRS EDGE 850/900/1800/1900
In conclusion:
1. Buying a tmobile HTC in the USA means you can only get 3G signal when using the tmobile network. When travelling abroad you might be able to use 3G, dependent on country.
2. Buying a AT&T HTC in the USA means you can only get 3G signal in the US when using the AT&T network but not on tmobile 3G. When travelling abroad you might be able to use 3G, dependent on country.
3. Buying an HTC HD7 from europe will be able to use neither the tmobile or AT&T network's 3G signal (as AWS 1700/2100mhz is different from normal 2100mhz)
Interestingly, what you may have noticed is that the 2100 3G band is common to all phones, this is also the most widely used 3G band in the world.
Therefore all these phones are fine with 3G everywhere in the world except the USA where the 2 leading GSM networks do not, for some reason, use the 2100mhz band as duplex *
* common question, how is UMTS 2100mhz different from UMTS AWS 2100mhz?
Simple, normal 3G UMTS 2100mhz is duplex (i.e. up and down link use the same frequency). In AWS, the up and downlink use different frequencies, AWS 1700/2100mhz means that tmobile uses 1710-1755 Mhz down & 2110-2155 MHz Up.
Only two networks in the world use AWS, tmobile in the USA and WIND in Canada.
in the rest of the world, where tmobile has a presense, it uses the "normal" 2100 3G band!
Wow, thanks very much colonel, that's an excellent explanation!!
So the T-Mobile HD7 is basically the Europe version with an additional radio (or whatever) to connect to the T-Mobile 3G network?

it has AWS 1700/2100mhz instead of the EU 900mhz
it retains the normal 2100mhz, although this is useless in the USA

Excellent, thanks for the clarification!
It seems that in South Africa all 3G goes over the 2.1GHz frequency but some operators are starting with 900MHz so all will be fine.
Can't wait to get one now!

I was wondering if there were any imported G Note owners in the LA California Market area that could test a situation for me...
I just came off of a 1 hour phone call with T-mobile tech support, they have told me that in the LA Market area they ARE INDEED running 1900mhz HSPA+ as of November 2011. They claim that the GNote should be capable of pulling in data on this band with a regular Tmobile SIM and entering the proper APN settings into the phone. I had this confirmed by a level 3 tech support agent and a supervisor, also from level 3 tech support.
If this is true, then we should ALSO be able to receive data on the 1900mhz band once the AT&T roaming agreements go into effect at the beginning of the new year.
Anyone who could verify this by actually using a Tmobile SIM and using the correct APN settings, your info would be much appreciated.
Well I am not in the LA area, but I would gladly test it. Although I have no idea how to change the APN settings.
Also, does this mean they are planning on supporting 1900mhz everywhere in the near future, hopefully?
T-Mo migrating their 3G over to 1900mhz makes a lot of sense really. Had the AT&T-Mobile deal gone through, their plans were to phase out 1700mhz AWS in order to make way for LTE using the same frequencies anyway. Since that failed, AT&T and T-Mobile are basically going to achieve the same thing through roaming agreements, but in order for that to work, they need to be fully compatible with each other. So, either AT&T needs to start supporting AWS 1700 compatible hardware, or T-Mobile needs to start phasing out AWS 1700 3G in favor of 850/1900 3G instead in order to be compatible with AT&T. The latter seems more likely to be the case, especially as that would mean that AWS 1700 could be freed up to allow T-Mobile to (maybe) roll out their own LTE network someday.
I can tell you in a few days when my SIM arrives, I live in that general area
