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.

Hello All,
I recently bought a 3G Cingular service plan with unlimited data. I have a Qtek 9000. Do you think I can use it in markets where cingular offer 3G to make use of video calls/ high speed internet etc?
Thanks,
Gilbert
The Universal only supports UMTS 2100 Mhz not the Cingular 1900Mhz based system.
Bummer. This is a sad day in the history of sad days :evil: Ok but I can still use my unlimited GPRS to surf the net, right?
With the new devices planned for this year, are they planning multi UMTS bands along with GSM quad/ multi bands?
Thanks,
Gilbert
You can only use GPRS on the 1900 network. If you're outta luck there are no 1900 masts in your area (only 850) and it will be a really, really sad day and you wished you had bought a quad band device etc...
There is also some rumour that US UMTS will not use the 2100 band - that would be a real bummer.
I remember in the US when the Jam came out there was two radio versions. One for the US, I cannot remember the bands and another for the rest of the world. But I clearly remember that it was a software issue and not a hardware as the software could change the frequency to match your requirements.
Does this exist for UMTS?
Regards,
Gilbert
this depends more on the antenna design, and how far away the bands are. The radio tuner should not be the issue.
Thanks for the reply. Does a software band switcher exist to do the switch to 1900 UMTS from 2100 UMTS?
Thanks,
Gilbert
The Truth
USA uses the 2100 frequency for US satalites this is why Cingular does not support the 2100 frequency. They will never have 3G on 2100, FCC crap the only thing we can only hope for is a hardware upgrade for the antenna but I doubt it. GPRS only works on 1900 so who ever told you the 850 crap doesn't know. this is why you can get voice calls in certain area but no data + if you only had an 850 towers you wouldn't beable to make a call scince you don't have that band on your device. I don't think there would be a way to hack it to use the 1900 mhz frequency because it would take a really smart developer that can do a lot more than registry tweeks to wirte a relay to the 1900mhz antenna. sorry guys.
I did a lot of reading on this last night. Rumor is Cingular is to start using the 1900 band for incoming and outgoing and then add the 850 band latter since the 2100 band is not available.
just a rumor
It is just a rumor. They already have 3G on 1900 and that's it, 850 is old technology if anything the 1900 tower are going to be eventually replace the 850 tower. Trust me, I live in LV where 3G is all over, GPRS, and 3G is only on 1900mhz if you look at the coverage maps for gprs vs the cellular coverage map you'll see what I'm saying.
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?

He's trying to verify if it's actually 850Mhz now. Still not 100% sure.
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
Hi all,
Mostly a lurker here over the years, love the site and forums - great community! I'm running latest JG4 Optus on my SGS with the new "2200 score" lagfix - awesome!
Anyone else getting really slow data on Telstra? I have tried telstra.wap telstra.corp telstra.internet telstra.iph all of these AP's give extremely slow data, and the phone symbol at the top flicks between 'H' (assume HSDPA) and 3G at times. I'm talking 0.4mpbs.
My friend is on Optus and his *cough* iPhone is getting 4.45mbps, in comparison my speed is nowhere near this speed. I am in metro Melbourne.
Anyone else have slow Telstra experience or know a trick or setting to help out - would be much appreciated!
Thanks all.
i could be wrong, but i dont think the galaxy s supports telstra network very well, if at all. dunno, not real tecchy, but its what ive heard round the traps. something to do with the bands the phone supports (900/2100 or 2200ish) and telstra is 850 something or other. smarter people than me will be able to clarify.
Correct, Telstra uses 850mhz and 2100 (apparently). But, only some variants support 850, and Telstra are releasing their own for that frequency. So I'd imagine that 2100 simply has lower coverage (Optus on the otherhand uses the more standard 900mhz frequency).
If you already own the phone, you may wish to consider moving to an optus based network (such as Exetel for Virgin). However, it is also entirely possible/probable that the galaxy S ships with a chip that supports 850mhz, and it simply needs to be enabled (I have seen threads which showed a way to apparently enable it).
Or, it may be just reception probs

It possibly does, but which country did you purchase it in? Remember, some countries might have had it disabled (because they don't use 850, or have other services on those frequencies).

Coverage in my area is usually great, I'm in Melb metro area and normally full bars.

Hi, thanks for all the information, heres the low down:

Bummer!
Multiple times ive looked up this phone in the past. Multiple times my dreams have been shut down because the frequency bands arent the same as Telus Canada. Multiple times have people told me, no, its impossible, wont happen. Then how come both the Windows Phone 7 and the dell venue pro site both have 1900/850 MHz EDGE? i realise EDGE isnt the fastest bug around but its much faster than GSM and its still is by definition 3G. and i was led under the impression that only GSM would work.
So what im wondering is that, ive heard that a new model for US is coming out in January, would the GSM/EDGE frequency be the same, just with 850/1900 UMTS difference?
And basically all i would be waiting for is a bamp from 3G to 3G+?
Telus 3G+
Telus in Nova Scotia HSPA+ network runs on 1900/850 (PCS/CLR). Its probably the same frequencies across the country.
I'm a new user, so I can't post links yet... however if you look at the telus mobility page and go to the Coverage tab, it'll tell you that they use 1900/850 for their 3G+
the wikipedia article on UMTS frequency bands also says telus uses 1900 and 850.
HSPA+ is part of the UMTS family. The Venue Pro lists UMTS 1900 and 850 as bands it can get... I'm assuming that means it can handle HSPA+
I'm just making assumptions, but it seems like the Venue Pro will run the HSPA+ network on Telus/Bell in Canada.
I sure hope it can, because I want a venue pro on telus myself!
Dont make a mistake, EDGE is NOT 3G and the frequencies the DVP uses for 3G, 900/1700/2100 will not give you 3G on the 850/1900 frequencies, that is for EDGE only.

That is correct.
Only 3 providers in Canada will enable you to get 3G with the Dell Venue Pro.
Those providers are Wind Mobile, Videotron and Mobilicity.
The phone supports AWS 1700, not UMTS 850 or 1900.

well... that put a serious damper on my fun ... I really wanted one, but not if it can only do 2G around where I live.
Now to see what bands the omnia7 supports... I hope I don't have to settle for one of the ****ty phones released in canada. Seriously, we got all the worst ones.
Iv been waiting on the dell venue pro seeing to it was the only Decent phone that would work here Where i live at&t Alaska. now im screwed.
