Will Touch 3G work with Tmobile/AT&T 3G services

Hi,
I am planning to buy Touch 3G or Touch Diamond. (Still confused)
However, can anyone tell me which one of these will work with US carriers 3G services.
The specs mention
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100 / 900
So, general latching on to US GSM networks and using Edge is not a problem, I know. However, not sure about 3G.
Whatever reading I have done shows that the 3G network is as per European standard. So I am sure I should be able to use 3G in Europe/Asia.
Can some gurus help me with this.
Appreciate your help

I have ATT, and no, the Touch 3G does not work because it is missing the 3G band used by ATT. I only get Edge in places where my old P3600 would get 3G.

Does this mean that this device will work at least for voice/SMS in Japan (which only has WCDMA 2100, no conventional GSM at all)?

Lock to 900mhz

Hey guys my ex-Orange is on Virgin AU these days, using it as a tethered modem but I need to lock down to 900 as the Opyus/Virgin 2100mhz 3G spectrum is saturated in Melbourne to hell with all these 2100mhz devices over the last few years, any idea where I can get an application to lock to 900mhz 3G ?
Im using the HK rom a kind XDA'er uloaded for us

Under "Start\Settings\Personal\Phone\Band" (translated from German) you can preselect some frequencies.

thats the problem ! the only option is 2100/900 mhz together, nothing else under 3G

try....
On my rom I have two things to change on that page:
Networktyp: There I'm able to decide GSM or WCDMA
GSM should help you with your problem.
Band: There I can select the frequencies, but as you mention, there are always a UMTS band included.
Good luck and regards from AUSTRIA.

Topaz does not work in US 3G network?

I got the Topaz from Europe, and I tried several ROMs but I just can't get it connected to the US 3G network. I heard the band is different, but is there any way that could possibly solve this problem?
Thanks so much in advance.

Also, is there a "2G" version of Topaz? If so, how can I tell if my phone is 3G or not?

No way to make it work, although if you are on att, you may get hsdpa in the few areas that actually have it. not sure what you mean by 2G, but it should connect to EDGE just fine

Take a look a the band located in your phone's option section. 3G would work if UMTS is 850, 1900 coupled with WCDMA

Network Type/Band Freq

Can somebody please explain GSM vs WCDMA vs UMTS for the bands?
My impression is GSM is 2G and UMTS is 3G and both can supply regular phone service? What's WCDMA then?
T-mobile USA is GSM 850/1900 and what else?
I was thinking if I specify what network and band to use it'll use less batter (ie. no 3g unless I really need it).

this is a really easy google search... or just go to wikipedia....really any search you would try will answer your question.
(you're half right, but mostly wrong)...here's some links for you

Well I did google already, but still is over my head when I look at the band settings in the TMO HD2.
If WCDMA = UMTS why is there a separate GSM/WCDMA network selection, both allowing bands in GSM and UMTS.
Sounds like GSM is older tech, meaning 2g, whereas 3g is the newer GSM, which is UMTS, which = WCDMA. Therefore, how can you choose UMTS band frequencies on a old GSM network?
Perhaps I'm not phrasing my question correctly. I'm asking these because of the phone settings. I'm trying to figure out if it's more efficient to just tell the phone to look for specific network/band for TMOUSA thereby saving time and battery.

is this just too simple of a question or not many people understand. anyone?

ok, instead of giving you a bunch of info, let me give you just what I think you need.
I'm guessing you're going to Settings>Wireless Controls> Phone>Band and that's where the confusion is coming from. This screen is wrong and the Bands listed there are wrong (they're from previous devices, and htc didn't bother to update that screen).
So, you have 3 main choices there that should be of interest to you as long as you're in the US on Tmobile's network: Auto, WCDMA, GSM (under Network Type).
Auto: switches automatically between GPRS/EDGE/3G (HSDPA, HSPDA+)
WCDMA: 3G (HSDPA, HSPDA+)
GSM: EDGE/GPRS
The only way that playing with the band frequencies could help you would be if you're just interested in Edge/GPRS since tmobile uses two different frequencies there (native 1900 and 850 roaming). For 3g however, Tmobile uses only (and concurrently....as in you need to use both to get 3g and not just one or the other) 1700/2100 frequency.
Long story short, if you're trying to keep the phone from switching between 3g and Edge and you're in an area that has constant 3g, set it to WCDMA. (but note that if you loose 3g but are in an area with Edge, it will not switch to Edge, it will just be 0 bars/reception).

thanks alot, that really clears it up. I don't have data connection besides mms so I figure I may set it to no 3g and save some battery.

[Q] Does the European Optimus 7 supports WCDMA 850?

I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks

I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.

Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900

Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.

Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.
