I haven't seen any specs for North American Galaxy Tab so I don't know if the AT&T version will have UMTS 850. I have ordered a Euro version that has UMTS 1900 so I presume it "should" work on AT&T 3G but I'm worried because what I can find on this subject implies UMTS 850 is essential for AT&T 3G. Can anyone with experience in US tell me how well the UMTS 1900 only works? Thanks.
Yes
To be more specific, it will if your city still has the 1900 mhz band. Check here: http://www.cellularmaps.com/att_850_1900.shtml

Thanks for the quick response and the maps (first time I've seen coverage maps by frequency, since AT&T no longer offers them) Very helpful and I feel better about haven ordered the Euro version.
Are there any owners of cellphones using the Euro 900/1900 UMTS frequencies on US 3G networks who can share their experience?
I live in the SF Bay Area and here the network is mainly 1900Mhz so the device works very well.
If you live in a market that got 3g fairly early, your network in probably 1900Mhz.
If you live in a market that only recently (1-2 years) got 3G, you might be on a 850Mhz network.

X1 has -
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
ATT - is
850/1900
why cant i connect to 3G here in the US ?
You may have a X1i. Which has 3G bands 900/1900/2100 and you live in an area with 850MHz 3G.
Since the X1a, which is the model with the specs you posted, hasn't been released yet (apparently ships today according to Sony Style), I doubt you have the right Model. You have the X1i.
No i have
GSM 1900-850 and UMTS 1900 850
says so in my settings.. but i dunno
it reads X1
not X1i
and has an FCC ID under the battery where the S/N is
Did you get it from US? Or overseas? Europe Asia?
If not from US, then its X1i version.
And I think the X1a was just released today, right?
Sorry, but you probably have the X1i, unless you got a very lucky prerelease of the X1a which has not shipped yet. There are numerous posts that are confirming that there is only 1900 on the X1i and not 850. This means that it will work in some 3g areas, but not all.
The X1i lists all of the bands in the settings menu despite the above info. It's a bit misleading, but even though the software lists both, it doesn't always mean that the hardware supports it.

Hi Uber,
You have an X1 also known as X1i
The UMTS is 900/1900/2100
Europe uses UMTS 2100 so you select setting 1= 1900/2100
USA AT&T uses UMTS 1900 in some areas, while in other areas it's 850
The reason your Xperia also have setting 2 as UMTS 850/1900
is for when you travel to a UMTS 1900 country like parts of USA
But since your device doesn't have UMTS 850
it won't work in a country with UMTS 850 like
Australia, Canada and some areas of USA.
Where in USA are you located?

im using AT&T here in the los angeles area. i got 3G no problem indoors as well as out. so hope this helps others. also...you might have to disable the hsdpa/hsupa in the advanced network. if you dont, you get the "H" symbol...which i heard is a little bit slower than 3G. hope this helps
Hi vicsingh71
Sorry to tell you but that is wrong as 3G is a max speed of 384kbps whilst HSDPA is max speed of up to 7.2mbps for download and i think HSUPA is 2mbs for uploading. Anyway super fast Data also called 3.5G is what these two are and they are both much faster and a better service then just 3G.
Marc
i also have a x1i purchased in the uk. i live in Los angeles and the 3g works perfect! The only reason sony made the x1a is to be able to sell it in the us. the x1i uses a qualcomm prossesor that is in litigation with nokia here in the us, so it cannot be sold here. that is why the downgraded the chip for the x1a. my advice is to get the x1i
Saw this news story, does anyone know if it is credible? The NextG Service is on the 850MHz band which is the same as Rogers/Fido in Canada and Cingular in the US...if all this is true then one of these unlocked would be 3G Compatible in North America...Thoughts?

Well that would suck for me because about 3 hours ago I got an iPhone because I really needed 3g already I do ally of browsing and videos but I like the touch he better....
What is the exact issue with North America and the Touch HD? I thought HSDPA was fully supported in our continent under most major providers. Just curious as I'm looking at purchasing one in the future.

The Touch HD that is out now operates on UMTS 900/2100. Telstra in Australia and the North American providers (except T-Mobile) use UMTS 850.
hopefully it is just some software that HTC did. cuz we do have that option to change it to 850MHz 3G in the phone but just nothing happens to it. If a flash can fix it then it should be ok. EDGE for me is pretty fast anyways in Toronto most of the time.

850 mHz is just one of the 2 bands needed to work on US 3G. you also need 1900 . my understanding is one band is for upload the other for download. don't get me wrong, it would be fantastic if the Aussie version was fully capable on US networks. i'll believe it when i see it. heck, expansys even has a note saying they have to confirm the 850mHz 3G band.
850/1900Mhz....
could someone please explain the upload/download at different frequencies paradigm to me?

This is incorrect. With at&t you do not need both. With just 850mHz you will be more than fine.
Now with T-Mobile you would need both 1700 and 2100 not just 2100 or just 1700 both. Just more reason to hate T-Mobile.
I am ready to take the plunge and drop the $ for an HD. I also will switch my number back to at&t from verizon. I guessi cna say almost ready. I really dont want to spend $800 for no 3G
Does anyone know how hspa in Canada with Rogers/Fido works? i.e. are dual frequencies required or is 850MHz enough to get top speeds? Thanks...
Has anyone brought one into the US and had any success getting a 3G signal ?
Some carriers in the US and Canada use 850mhz such as AT&T and Rogers but they also use 1900mhz. It really depends where you live... Whiich city, state etc
1900mhz is growing in popularity in the states.

Sadly, no 3G for me.
You do not need both 1900 and 850. Its only tmobile that u need both frequenes but they use 1700 and 2100. As long as u have ether 850 or 1900 (depending on what freuency ur area uses) u will have 3g with at&t.

No, the *network* you use may be present on more than one frequency, but its not 850 being uplink and 1700 being the downlink.
When we talk about UMTS the downlink is around 850/1700/2100 but the uplink is always a few MHz below that. (to be pedantic, the UMTS specification specifies the exact downlink/uplink separation)
I can't imagine HTC producing a UMTS 850 phone that won't work on ATT/Rogers and Telstra . Telstra only needs the 850 band so HTC can add in whatever extra the US providers use. It will probably be the same bands supported by the HTC Hermes and other phones common to these providers.
for AT&T, you do NOT need both frequencies (850 and 1900) for 3G. They don't HAVE both frequencies in most areas. It's one or the other.
And yes, T-Mobile US sucks ass...

Well I stand corrected then. This is good news then. Just need somebody in the US to buy a Telstra HD and see if it works. I guess it will be dependent on the area though. If you don't have 850mhz.
Lol i guess it took a senor member to say it for anyone to believe it. I only said it in the first page lol. Lets see what happens when the aus model comes out.
So it is decided then IF the Blackstone is introduced by Telstra and working on their 850MHz 3.5G Network THEN it has the opportunity to work in both the US on Att and Canada's Rogers/Fido...I will wait for this device, purchase it and let the board know if someone else doesn't beat me to it!
P.S. does someone think that this release may be with the Android OS for Telstra? It was the Telstra reps that were commenting at CES 2009 regarding Palm Pre and how the next Android phone that they were testing kicks it...who knows probably coincidence...
Does anyone know what's the HSDPA for AT&T in US? Is it 850/1900?
I know that At&t is not 850 as people from the rest of the world who buy iphones 3g in usa can use them on 3g in their countries and only america use 3g on 850
HSDPA is 850/1900 for AT&T. Look at the specs for some of the 3G phones on their website, they should all say 850/1900 UMTS
This is what it looks like to various HTC mfg phones....in Ca.
on my ATT 8525(att wm6.0 rom)= 3G:850, HSDPA:1900
No matter which network is being used 3G is what is displayed
On my X1i only HSDPA: 1900 this connects only in the major metropolitan area! in Ca. I live in a small commuter community so, HSDPA is about 15 mile out of range north or south of me....But we do have 3G: 850(what att uses in their fringe areas) so no joy for my X1i

Download Advanced Configuration Tool (search) and you can turn on HSPDA and the icon. I've read some people had trouble with the setting sticking; however I've had good luck with the stock ATT Rom and latest 1.12.25.19 (I think) radio. Didn't do any speed tests to actually see if it made a difference other than anecdotal evidence.
Bands :
UMTS 2100 / 1900 / 850 MHz
GSM / EDGE 1900 / 1800 / 900 / 850 MHz
HSDPA / HSUPA:HSDPA 7.2 Mbps / HSUPA 5.76 Mbps
That above is directly from their Tech page. Is it 3G or not.?
http://www.dell.com/content/products/productdetails.aspx/mobile-streak?c=us&l=en&s=corp
i get 3g/h so yea....it is.. /shrug
Yes it is, and work very nice I do download at 200kbps, and by wi-fi around 15mbps.
I never seen before any mobile doing download so quickly.
Sent from my Dell Streak using XDA App
Same here its a lot faster on 3g than the last two wm phones i have this is my first android so dont know about other devices
does anyone know if the 3g/HSDPA will work in europe if i import it from the US?
i'll be in NY for the summer, will i be able to buy it unlocked from a physical store?
thanks
My bad for not stating I was interested in T-Mobile 3G.
Isn't that the 1700/2100 HSPDA band? Did not see that in the tech specs.

The 2100 frequency should work on 3G worldwide, right? I also asked a representative in chat if the Streak will be sold unlocked on their website and the answer is "we don't know yet, check back when the product is actually on the market".
I did not know what was exact, until I read this below
http://www.streaksmart.com/2010/07/dell-streak-with-tmobile-3g-bands-out-in-the-wild.html
I'm sorry if I am repeating information, but I thought I would explain in case anyone else was wondering.
UMTS/HSDPA/HSUPA are 3G technologies, so yes its defintiely 3G.
The 2100 MHz support should help the dell Streak work in countries other than the US and on networks other than AT&T. BUT, keep in mind that this will not work with T-Mobile's 3g network.
T-mobile uses 1700/2100, but the 2100 here on the dell shouldn't help much, because the 2100 is used for downloading while the 1700 band is used for uploading, and I'm pretty sure you can't use 3G download without 3G upload connected too. So if a carrier outside the US has a similar setup as T-mobile USA, with the split upload and download bands, then you could find yourself without 3G on that network too.
Hi All
I am visiting the USA in September for holiday and am doing a bit of travelling while i am out there. I was going to buy a prepaid sim to use with my SGS II which is sim unlocked. I am visiting Los Angeles, San Francisco and Vegas what network would you guys recommend for coverage and costs ?? it would have to be a GSM network.
Thanks
I would say T-mobile because they have a awesome pay as you go plan
I would say T-Mobile
T-Mobile and AT&T are the only ones compatible with your SIM. However the SGS2 is only going to get EDGE on T-Mobile if you're wanting data. It's compatible with the HSPA for AT&T however. From what I understand there really isn't a difference in price between the two for prepaid. Nothing to make a difference when you're taking an international trip anyway.

European 3G bands are different than US ones. In Europe the UMTS band is operating on 2100MHz. AT&T operates it's 3G service on 850 and 1900 MHz.

Yeah but the SGS2 has the 1900MHz band in it, so it would work on AT&T's 3G network, but only on T-Mobile's EDGE.

You need both bands for AT&T 3G. 850 provides downlink. 1900 provides uplink. In Europe, 2110 is downlink and 2150 is uplink. It is normally just included in one spec of 2100MHz. The 850MHz band in this device would only provide 2G speeds.
AT&T is your best bet.
