Product: X1
Opinion: The spec sheet online says the X1 seems to be a penta-band UMTS phone. I highely disbelieve it supports all 5 bands that it says it does. It's most likely tri-band. What bands does the "X1a" <--(US Version) support?

Dear Todd,
Thank you for contacting Sony Ericsson Online Support.
Try this following spefication for the Sony Ericsson X1. Also the storage might vary depending the phone configuration since free memory may vary due to phone pre-configuration. But the GSM networks will remain the same the networks incharge to make phone calls. Just beware where the phone is bought since the HSPA will be different since it will be 2 version in X1i and X1a the "i" is internation the "a" is for the Americas. The HSPA is incharge for the data internet connection wich the X1i will have 900/1900/2100 MHz and the X1a 850/1900/2100 MHz
Video recoring in X1i
1. MPEG-4: 30fps at VGA
2. H.263: 30fps at VGA
3. H.264: 15fps at VGA
Video recoring in X1a
1. MPEG-4: 24fps at QVGA2.
2. H.263: 24fps at QVGA

That Spec sheet is wrong. X1 is released in Sweden and it definitely has more then 128MB ram. Also VGA video recording on the X1a will be reduced to 24fps QVGA because of patent issues with Qualcomm in the US. So I have reason to disbelieve what you are telling me. Do you have anything more current?

If what he says was true that would be nice but this guy sounds like an idiot. Probably from India? Also, just noticed the website he linked there says the X1 has 128 mb ram lol.
---EDIT---
Now this 2nd respone looks as though he took a moment to actually look. An btw I never agreed to any terms of service nor confidentiallity agreement when I sent these e-mails out so I believe them stating that this is strictly confidential is like suggesting I keep it a secret.

Thank you Kloc,
It looks that we will never know until we get one in our hands.
That email is typical SE. The link is old they say 128MB
In the other hand all the people that have new Xperias report tri-bands.
but the email calls for quad band. so what gives...

looks pretty autogenerated to me

Wikipedia is useful

It says X1a in the manual without the 1700 band. I have T-mo and it would be great if it's included but I'm doubting it now. I'll just have to wait till the phone is out to see.

Yes but 2100 is also the widest deployed UMTS band in the world therefore it would make sense for them to add it for a 3G world phone. I guess it don't matter to me because I have t-mo and the only 3G provider in my area is Verizon and there PDA plans suck.

HSPA 850/1900/2100 Bands For North America
These are the {DATA} bands in Noth America HSPA 850/1900/2100 OK! T-Mobile USA uses the 2100 HSPA band in the USA.

See How People Take Things Out Of Context
I'm only talking about the {DATA} Bands in North America, not the talking band 1700 MHz UMTS, see how people take things out of context. I'm talking about one thing and they talking about another thing......!{LOL}

So are you saying T-mo 3G can run on 2100mhz alone for data only?

Yes! Yes! Yes!

That's what I'm saying, We all know that you need both 1700/2100 MHz UMTS bands on T-Mobile's USA 3g UMTS Network. All I'm saying is the 2100 MHz HSPA UMTS side is the DATA side and used for {DATA} transmission, that's all.....!{LOL}

850 Band (hardware) missing?

Over at http://www.xperiax1.net/forum, there is a report that, even though the phone setting on the Xperia shows support for 850 Band, the hardware appears to be missing from the Xperia that was shipped from Clove.
I cancelled my pre-order from Clove until this gets sorted out.
Here is the post:
"Guys,
OK after checking and checking again and despite being told that the X1 supports 850 and 1900 3G the device turned up today and guess what? It does not so I can't get Rogers 3G out here in Canada!!!!!!!
Going to the phone settings shows that the device can be switched into the correct mode but doing this seems to have no effect.
I can only guess that the device has the software to support the band but the hardware does not.
So be careful folks, while you will get great Edge coverage you will not be able to get 3G!!!!!!
You have been warned!!"

I think it's pretty well established that the X1i has UTMS bands 900/1900/2100. Europe uses 900 and 2100, and most reports say the 1900 band is working on ATT's 3G. Of course this requires you to live in an area with 1900 3G coverage, not just 850 mhz 3G. Sounds like he lives in an area where Rogers only has 850 mhz 3G available.

I looked at the 1900 and 850 3G Band coverage in the US on ATT. 1900 Band actually covers more area than the 850 Band. Is there any disadvantage to only having 1900 Band in the US on the Xperia?

850mhz is good for getting a signal indoors, since lower frequencies can travel through obstacles better. So no 850mhz support means you might get a weak 3G signal indoors, or no 3G signal at all.
Then again, you might just be living near a 1900mhz cellsite/tower that gives you a strong signal indoors, so YMMV.

Thank you. So do phones with both 850 and 1900 Band support use both Bands at the same time? Or, if not, how does the phone decide which band to use. Is the 3G speed the same on either Band, provided you get a good signal?
One issue that sways me more towards the X1i is the better video frame rate - 30 fps vs 24 fps on the X1a (because of the stupid Qualcomm patent issue here in the US)

Phones with both 850 and 1900 only use one at a time, but they can switch transparently from one to the other in areas with coverage from only one band. Exactly how it chooses which band I'm not sure (it could be network load, signal strength, etc).
Technically speaking, 1900 can offer more speed because the faster frequency allows for higher data rates. But since it's all just one 3G network, there should be no significant difference in 3G speed between 850 and 1900.
The Qualcomm patent is a tough reality for people that want the X1 for the US, and unfortunately there's just no way around it. If you happen to travel internationally frequently, the X1i will obviously be the prudent choice (you still get AT&T 1900 coverage, but also 2100/900 for virtually every other UMTS network in the world).

I found a new article with someone claiming to be receiving ATT 3g in an 850 only area. He states that none of the 1900 only devices he's tested receives a signal. He also said that SE reps he contacted claimed X1i support for 850 3g bands as well (yeah, I know not that credible).
http://www.pocketnow.com/index.php?a=portal_detail&t=news&id=6165
Not getting my hopes up, but can anyone with an X1i confirm any of this?

High speed on cingular with X1i

Hi Everyone,
I got my X1i on Tuesday. It's obviously a UK import, but so was my TyTN II and it worked great. When I got everything set up, I couldn't get more than 200kbps on dslreports. I put the sim card back in my TyTN II and retested, and got 1.2Mbps.
If I turn off HSDPA/HSUPA the data rate drops to 30kbps. I've played with every combination of data and voice bands and can't get the same performance as the TyTN. I do notice that my X1 never shows the H icon in the status bar like my other phone to indicate high speed (HSDPA).
The bands are exactly the same with a minor addition.
GSM: 900+1800 UMTS: 2100 + 800
GSM: 1900 + 850 UMTS: 1900 + 850
UMTS: 2100 + 800
AT&T seems to run on the middle one.
Does anyone have any thoughts on what could be holding my back? Same SIM, same data plan, etc.
Thanks very much in advance!!!

Hi,
Where do you live? Could be you only have UMTS 850 coverage... But, could also be something else..

I live near Reno, NV. The wierd thing is I literally power down, move the sim to my TyTN II and bingo! I get incredible speeds. Short of getting into the registry I have gone through and confirmed all the GPRS and HSDPA settings are exactly the same.

I think what dbond45 was saying is that you might be in an area that uses 850 band which isn't actually on the x1i. The tytn II on the other hand has the 850 band from what i understand so that might be why ur getting great speeds with ur tytn II.

Ah, so you're thinking that even though it says it supports 1900+850 in the control panel, the 850 band may be disabled in the radio? I'm pretty technical, but would have no idea how to test that. Any ideas?
By the way, thanks for talking this through with me. I hope it's benefitting others too.

Yes from what i've read all over the place that the 850 radio is disabled. I know that even though the software says u can enable those bands it doesn't actually mean u can. I have the touch pro and it has all of the different bands in the settings and we all know no one can get 3G in the US. So it looks like that is what ur running into. I've read on howard forums at some point a way to test to see if u are working on the 850 band but i don't remember how they did it.

Bxsteez,
The program is fieldtest.exe, and you can find it under windows in your file explorer on the X1, once in WIndows, scroll down to fieldtest.exe and run, although I'm not sure what all the values me..
There is a dispute as to whether the X1i has UMTS 850 (see pocketnow.com post, but, IMHO, I don't think it does, although I wished it did)
Lemme do some research and see if I can find what band Reno is running on. It's very likely it's 850 3G since a) it's a newer market, and b) it's a rural area compared to large cities which use 1900 mhz UMTS...

From what i was reading on howard forums Canada only uses UMTS 850 and the people who have the x1i are reporting only edge speeds.

Indeed you all were right about the discussions on Howard Forums. Read through a lot of them. Thanks for the pointer to fieldtest.exe. I'm digging through it now. I'm hopeful that S/E just threw a software switch in their stack for 850Mhz so the X1i wouldn't carp any of Cingular's sales on the upcoming X1a. Hopeful and maybe a little naive.

X1 on AT&T
I had a similar instance yesterday, sent the X1 back. The same 3 choices for UMTS in WM Phone settings, I selected the 850/1900 bands. I got the H but it was slow. Moved my SIM back to the BlackJack II and worked just fine.
I think the ROM or WM6.1 Stamp they are using is incorrect.
The Xperia Box, on the white label shows UMTS EU1 US3 EU4 I believe which to me would mean 900/1900/2100 I am not positive about the last EU being 3 or 4 since I have mailed the phone already. There are a lot of listings on ebay which show UMTS 850/1900/2100 which I truly believe is incorrect and are being used from a Feb 08 page on gsm arena. Expansys USA told me they had both flavors, then the next day all you see on the US site is the 900/1900/2100.
The US ver is not released ( X1a) from what I read here and everywhere else.

1. There is no dispute. Only dumb people. the X1i DOES NOT have 850mhz UMTS band, the hardware isn't even in the phone. It falsely displayed 850+1900MHZ because it does 1900MHZ and WM assumes that if it has 1900 it must have 850. It doesn't..
2. Reno does in fact run a predominately 850mhz 3G networking using At&t (not cingular, its been over a year since they got bought out) Your speed is likely because of this. Oddly if your phone is set to auto negotiate networks it should pick up EDGE service and show a "G" does it display a G rather than an H? You said the H doesn't display when you force 850+1900 UMTS right? The question is what does come up? Signal strength etc.?
If you import a phone from the UK you need to be prepared to be disappointed with speeds, simple fact, most UK phones don't even support 1900mhz, its there for roaming purposes on the X1. Same reason the X1a will have 850/1900/2100 UMTS. 1900mhz band is the weaker of the 2 used by At&t... 1900mhz was the first frequency they used, they used it so save costs and setup a marginally OK 3G network on a larger area. 1900mhz being a higher frequency means it can travel further than 850, this results in slower speeds and poor reception depending on your location from the nearest tower. 850 is lower frequency and there for more dense, this translates into faster speeds and better reception. Most new areas of at&ts 3G network are spread around with 850mhz. Older markets are a combination of 850mhz/1900mhz and some just 1900mhz.
The point is, if you are blissfully unaware of all this then your best bet is to send the phone back and wait for the US release.

FYI: The data transmission speed doesn't depend on frequency. Both 850 and 1900 bands are capable to provide the same speed.

Actually, I along with many others are fully aware the X1i does not have 850 UMTS listed on the box, in the specs, etc. I even made a post about it. HOWEVER, there is a VERY SLIGHT chance it does, and SE never mentioned it in the specs for some unknown reason. If you go to pocketnow.com, Brandon CONFIRMS he spoke to 3 SE reps from the X1 support line who said the X1i had 850 UMTS support. Only 1 said it only had 900/1900/2100 UMTS as listed on the box. 3/4 reps saying it has 850 UMTS, along with the fact he supposedly only gets 850 UMTS where he lives, and is getting HSDPA on the X1i leaves a glimmer of hope for everyone out there, even if it is dismally small.
As far as the "false display" 850/1900 mhz option it is not so much a false display as a software option on most HTC phones, including the euro touch pro...
Anyways, I'm getting decent HSDPA coverage in Chicago...

They may output the same speed initially, but 1900 you usually get less bars depending on your location to the tower and less bars means slower speeds.

X1 not working with USA 3G ?

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.

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

January 22nd North American 850MHz HSPA 3G Blackstone...

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.

I can't remember which but one is used for uploading and one is used for downloading.

You are exactly right. YOu need both 1900 and 850mhz

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...
