if the phone only supports 1900MHz on 3G band, can I still get 3G data from AT&T?

Did you find your answer?
I have a GSM Touch Diamond and there's no way to use the US 3G even if you have a 3G sim, we discussed it in the Diamond forum and people said it's just not possible. Is this the case with the Blackstone or are you able to use 3G in the US?
if you use a 3 sim you can get service if 3 got a roaming agreement with an usa isp
if the usa isp don't use 3g services on the hz's the rest of the world use you can only get
2g or 2.5g (edge) service
the Telstra Touch HD version (Blackstone - T8285) uses at&t's 850 3G band. it works quite well in the US as long as one is in an area that uses more 850 3G towers vs. 1900 3G towers.

So it'll be the same 3G and the same speed as if it were an AT&T phone (like iPhone etc.)?

it's 3G from at&t, period. as i mentioned in my post, the Telstra HD is limited to using at&t's 850 3G band. at&t uses both 850/1900 to deliver 3G. if you're in an area that uses only/more 1900 3G towers then you may not have 3G access. i believe Phoenix, AZ is an example. can't comment on the speed with an at&t phone because i don't own one. the pic below is an example of the speed i get with my Telstra HD on at&t.

If there's 850 towers but more 1900 towers then the 3G just won't work at all? It won't just connect to the 850 ones?
I live in Houston, TX and commute between there and Austin, TX.

i can't say if it won't work at all. for example, if there are 100 towers and 95 are 1900 and 5 are 850 and, you live near an 850 tower, (theoretically) you should get 3G access. using your example, i would say you'd be connected to Edge more often than 3G.

if i remember correctly, there's a user here named tucomora who lives in Houston and has a Telstra HD. i believe he indicated that Houston may have more 1900 towers than 850s. but, as you may know, at&t is adding more 850 towers nation wide. i suggest you send tucomora a PM to get his perspective on using the HD in south texas.

I looked for tucomora, tucamora, tacamora, couldn't find anyone.
Would you not be able to go into the phone's settings and disable the 1900 band or something? I have a Diamond on AT&T now and it's between upgrading to an HD or waiting another month and signing up with Sprint for the Touch Pro 2 (or Palm Pre now) and then just looking like an idiot carrying 2 phones around.

why would you want to disable the UMTS 1900 3G band? if there are no 850 3G towers, you won't get 3G service you'll get EDGE instead. my phone options are set to Auto for GSM and UMTS and if there are no 850 3G towers it switches to EDGE. simple as that, not a big deal for me (and not implying that it is to you). you can change the GSM/UMTS settings to seek/use only 850/1900 3G towers, but in my experience, if the HD doesn't find an 850 3G tower, i won't have a phone signal, period. if you're in the US and want a HD with 3G capabilities, you get the Telstra Touch HD and accept the fact that having only one US 3G band (e.g., 850 3G) will limit 3G access in some areas.

If there are 850 towers but just not as many as 1900 towers, you could disable 1900 so it only connects to the 850 towers and then you'd have 3G, right? That's what I was saying. I have EDGE on the Diamond but it's so slow it makes me not want to use it most of the time.

uh, no it doesn't work like that. the phone is going to lock onto the strongest signal possible. if it sees a stronger 1900 signal, that's what the phone will use. if you (could) disable the 1900 band and you're in an area with 1900 towers, you would not have ANY signal at all, no phone, no data. based on your level of concern, wait for the at&t TP2 (or whatever it's called); then you'll have no worries about 3G access.
Thanks for all the help, I just ordered the T8285 so I'll let you know how it is. Will I be able to use all my Diamond accessories with the HD (extra batteries, chargers, etc.)?

chargers yes, batteries no. The Telstra ROM that comes with your device will have its internet connection settings locked to Telstra (which we can't obviously use in the US). this means you won't be able to access the internet from your phone until you add at&t's connection settings. i never researched methods to add at&t's connection settings so i don't know if they exist. i flashed HardSPL to my device so i could install a custom ROM. i suggest you click the link in my signature and learn about flashing new ROMS. hope you enjoy your device!
Thanks. I looked at some accessories on ebay and they all say for t8282 (for example http://cgi.ebay.com/o569-2in1-Deskt...ries?hash=item3352c2143b&_trksid=p3286.c0.m14 ), are the batteries for the 8282 and the 8285 different or will this work?

T8282 battery works with T8285. essentially, accessories for the T8282 work for the T8285. the only difference between the phones is the radio bands.
I have a tmobile vibrant phone (hardware only). According to the phone specs i SHOULD be able to get 3g signal with my fido sim card since the phone seems to support all the same frequencies as the Canadian i9000.... but i only get edge.
If you guys are getting 3G with fido or rogers sim cards, did you have to set anything special in the phone settings?
Thanks!
Vibrant T-mobile 3G runs on 1700
that is why you only get EDGE (2G)
Fido, Rogers & Bell runs on 850 & 1900 for 3G
On my way to work today this is what i saw in the network box.
inside my house - EDGE
Outside my house - 3G
back country roads to work - i saw just G or no signal (normal i loose signal with my iphone and blackberry on there)
at work - back on edge
So i DO get 3g somehow! or is it just teasing me by showing 3G?
i read somewhere that the t-mo vibrant does have 1900 as one of its 3g bands, so this is why your phone has been able to pick up 3g at times. the problem for you is that rogers/fido mainly use the 850 band. i had the nokia n97 mini that had the 1900 but no 850 and while driving around most of the gta i would get 3g, but when i went into buildings, houses, etc, it would drop to edge.
Maybe your phone supports 1900 and not 850 MHz? Or the oposite? That would explain why you would get bad UMTS coverage.
@hondaguy you were faster than me

To my knowledge the T-Mobile Vibrant does not support the major Canadian 3g bands. It is quad band 2g, which is why you are able to get edge but it is only 2 band 3g, at least according to this spec sheet:
http://pdadb.net/index.php?m=specs&id=2439&c=samsung_sgh-t959_galaxy_s_vibrant
T-mobile uses the 1700 and 2100 UMTS bands for 3g, Bell/Rogers/Telus/Virgin/Fido use 850/1900 UMTS bands for 3g. Therefore the 3g radio on the Vibrant is not compatible with these networks.
However, WIND mobile uses the 1700/2100 UMTS bands for 3g and you can use unlocked T-Mobile phones to their full ability on Wind's network. Wind is only in major urban centres though so this may not help you if you're not in the city. Hopefully you are as Wind has a pretty sweet unlimited data plan!
http://shop.windmobile.ca/
On the other hand according this this article from Engadget:
http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/
If they're right that the Vibrant is somehow capable of AT&T 3g, it would mean the phone has to be tri-band UMTS: 850, 1700, 2100 (or 1700,1900,2100) as AT&T uses the 850/1900 bands like Rogers/Bell/Telus.
This doesn't make sense to me why T-Mobile would do this. The 850/1900 bands are really only used in North America on competing carriers, so it doesn't give the phone "world" capabilities, the 2100 band does that. Why they would add a feature who's only purpose is to make the phone work on competitors' networks is a mystery to me but Engadget seems to have a picture that confirms it. If this is true than an unlocked Vibrant should technically be able to work on Rogers/Bell/Telus/Fido/Virgin 3g, but only if it is unlocked. I'm pretty sure that T-Mobile sells their phones SIM locked to their network, have you unlocked yours?
~Edit if it does have 1900 as the third band the above posters are correct in that you will get minimal 3g coverage as 850 is the primary in Canada.
yeah i wanted to switch to Wind Mobile for the $35 true unlimited data plan, until i found out they don't work with normal 850/1900/2100 phones
only 1700 / 2100
I bought this HTC Aria from USA and use it at my country (Indonesia) But unfortunately the signal is capped to search only gprs or edge, cannot hooked to 3G or hsdpa network..
I also have the asian market Aria, that works perfect in "wcdma only" netwotk. It don't have at&t logo on the upper right screen.
Question is how to make this at&t Aria working on my country wcdma network, bcoz I think that hardware already supported.. I just don't know how to hack it
I believe that its all about software or radio file or something like that , so I put my question here in this sub thread.. So sorry if I do a wrong post.

I think it is more a frequency issue than a lock issue. This is a world phone and no frequencies are locked. But if your carrier doesn't use the same 3G frequencies, it will not work on 3G. The 3G frequencies for the Aria are 850mhz and 1900mhz. Your carrier is probably using 900mhz and 2100mhz for 3G. Your only fix (if this is your issue) is to either buy another phone or change carriers.
Not to threadjack, but do any US carriers use the [apparenlty] more common 900/2100mhz for 3G?

Nope. Neither AT&T or T-Mobile use 900/2100 for their 3G frequencies. AT&T uses 850/1900 and T-Mobile uses 1700(AWS).
The Aria should work
HSPA/UMTS/EDGE/GPRS/GSM; Dual Mode UMTS/HSDPA/HSUPA (1900/850MHZ) & GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ); HSDPA/UMTS (3GPP Release 5 Compliant; 7.2 Mbps Enabled) EGPRS Functionality

It's supposed to be a quad band.
No the HTC aria is not quadband for 3g or hsdpa. Basically there is a US versiont the 850/1900 . In Taiwan they released another version with the 900/2100. So if where you live doesn't have a place that uses the 850/1900 your basically stuck w/ 2g speeds.
I recently broke my phone screen and have a year and a half left til my upgrade. In my down time i've been looking at phones from china and was wondering if this one will work on my At&t 3g?
5.7'' Unlocked 8MP Android Quad Core GPS 3G DaulSim SmartPhone AT&T T-Mobile 8GB
2g network gsm 850/900/1800/1900

In order to get 3G on AT&T, the phone has to have GSM bands of both 850 and 1900. If it only has one you get 2G.
This phone has both.

So then even though the specs say
2g network gsm 850/900/1800/1900
3g network umts 850/2100
it still will have full 3g coverage for att?
Oh I didn't see it separated like that..
Yeah the UMTS needs to be 850 and 1900, so that is Euro 3G, but it would probably only get 2G here.
Sorry for the confusion.
ok so look for phones with both umts 850 and 1900
