Question about my new Qtek 9000 and T-mobile network

I just got my Qtek 9000 and I am so impressed with it! It's a great convergence device. However i have a question for those in the US with T-mobile.
I'm in the CA SF area and have a plan with T-mobile. I noticed that I only have the options of EGSM+DCS1800 and PCS1900 under the Phone settings>>band>>GSM Band. So i'm assuming that I'm not able to access the 850 band that T-mobile uses. I noticed that when I use the phone, it says Cingular instead of T-mobile. Is there any way that I can access the 850 band? Do I have to get a new SIM card or is there another way? Thanks ahead for your replies!

Have you read the specs? The Universal only supports 900, 1800, and 1900 bands.

Just want to check, it does still work doesn't it? TMobile arn't the most accurate company in their specs, and they sold this phone to me as being 100% campatible with their US networks.

Tmobile uses the 1900 band on their own network, but based on roaming agreements their phones can use other companies' 850 band, mostly in rural areas. As long as you are in a major Tmobile area, you will receive a 1900 signal, but if you are out in the country away from any major city that Tmobile has towers in, you may not get a signal because the Universal does not support the 850 band. This is the same for Cingular subscribers that use the Universal in the US.
I'm waiting for HTC to release a version of the Universal that supports 1900 UMTS since Cingular rolled that out in the US. The Universal is stuck with GPRS for those in the US.

Duh! I guess I didn't read the specs close enough. I swear it said 850 instead of 900. Oh well. Is anyone in the SF bay area getting any decent connection to T-mobile's GPRS? Mine's slow as sin. If I can't get it to improve, I think I'll pass on the $5.99 T-zone plan.

HSDPA technically possible on Universal ?

Hello,
as here in Austria the market leader Mobilkom Austria is opening up HSDPA *NOW* I'd be keen to know if the HTC Universal is technically able to use this advanced 3G coding scheme with just an update of the radio firmware!
This question also goes to anyone from HTC, who is surely also reading here.
I think this question can be ultimately answered by yes or no.
Anyway, my thanks in advance.

HSDPA is a pimped up version of UMTS and is backwards compatible with UMTS. HSDPA supports 1.6Mbit while UMTS supports 384Kbits. Any Universal device that connects to the HSDPA network will connect at 384Kps, the maximum speed that is technically possible for a Universal device.
However, as other companies such as T-Mobile Netherlands have done, they *may* limit their UMTS connection speeds to 64kbps for cheap flat fee subscriptions and 384kbps for full price UMTS subscriptions. What they would do with HSDPA subscritions I do not know.
So, NO the Universal devices will not be able to be upgraded to HSDPA, since this would require a hardware modification, not a software upgrade.
but, YES, the Universal will be able to connect to HSDPA networks, but only at UMTS speeds.

Thanks Wiz for your swift (only 10mins after my posting) and concrete reply.
The strategy of T-Mobile NL is interesting. Didn't know about that.

I'm not sure I agree, I think technically it may be possible that a radio upgrade could support HSDPA (I hope so) as various other vendors have announced software upgrades. (eg Acer on their notebook range)
Afaik UMTS and HSDPA are use the same base technology.

I am afraid you're wrong there. HSDPA support has two components. A hardware component and a software component. While manufacturers may decide to add HSDPA hardware support in their devices from the beginning, they often (may) decide to wait providing the accompanying software support until Telcos have provided their requirements in protocols etc.
Since the Universal devices have no hardware support to accomodate HSDPA, a software upgrade would be impossible (and useless)
I guess it could roughly be compared to the days the faster modems were coming out, and all the older PCs turned out to have too slow serial ports and too small buffers (UART chips) to accomodate the higher transfer speeds. There, the hardware support was not available either, so while you could go and connect V-anything to your PC, all you would get was corrupted dataflows

That is indeed a pity since the Universal successor (with HSDPA) is only planned for 2007 release and HSDPA will be available next week where I stay.

Well, since HTC are currently struggling even to get UMTS support sorted, HSDPA for the time being will remain out of reach for now .... sorry

hspda
hspda in the USA will never work USA uses the 1900mhz frequency for HSPDA the universal uses the 2100mhz band

Colonel, SiliconS & Gajet please note.....
Even though I am not using the latest ROM but I am using the radio 1.06.00 ROM the UMTS aspect seems fine (okay not good with weak signals compared to my O2 3G datacard) on my XDA Exec.

the universal does not support hdspa as it has a MTM6250 chipset. Perhaps future universals will be made with the MTM6260 which does. rgds:

HSDPA and the UNIVERSAL ?
AT&T/Cingular are in the process of rolling out their HSDPA network and a handful of cities are using it; NOW is the Universal capable of this....I asked a similar question about the UMTS 1900 MHz being activated so it could be used in the states; Granted I was given some very good replies but I am still curious. Over the past week I have been talking to some other engineers in my field and have found that a great number of things are possible with the Universal, it has the architecture to support this, SUPPOSEDLY ! Now lets look at UMTS as a whole; then HSDPA ! HSDPA is a software upgrade to existing UMTS software, that's all ! SO is it possible that we can have HSDPA on the Universal with an upgrade to the radio stack, I think YES !...and the bands should also be able to be activate, current UMTS 2100 MHz to 1900 MHz so it becomes dual band...the other is the GSM 850 band ! That apparently can be activated !...HOW is the big questions....Most of the HTC is limited by software; not hardware...its existing hardware has been built with scalability in mind...I just hope that some one can figure out the radio stack updates to facilitate this functionality !

PabloPicasso - no and no
universal is limited to 2100mhz and non-HSPCA. look at my link above

I just wanted to make a comment on this point. From what I know, which in all rights is limited, UTMS standard is characterised by two channels. An upstream and a downstream. In order to meet UTMS specifications the following would have to be met:
"The specific frequency bands originally defined by the UMTS standard are 1885-2025 MHz for uplink and 2110-2200 MHz for downlink."
This means that when North American countries move to this standard, wouldn't the Universal work 'as-is'?
I obtained this information from wikipedia by the by.

Cingular 3G in the US

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.

Interesting.......no tweaks?
Just have to see....3G won't be available in my area until the beginning of the year anyway

UPDATE:
T-Mobile 3G works on my I-Mate Jasjar in the Jacksonville Florida area. The only adjustments I had to make was a minor MMS settings change.

Anybody in the northwest US able to connect to T-Mobile's 3G network?
I try to force my band to WCDMA and specify the UMTS freq as 2100, but then it simply doesn't seem to want to register with the network. When I set it to auto, it appears to simply be using GPRS.
Somewhat related, anybody know of a way to force displaying an icon indicating EDGE vs default GPRS connection?
Edit: I just recalled that there's no EDGE support on the Uni, unless I'm mistaken, so disregard that...
Edit (again): So if I'm understanding this properly... The Uni only operates on UMTS/WCDMA/whatever 2100, not 1700, which T-Mobile US uses. It was designed for uk/other 3G usage, not future US 3G usage. So we've got 3G support outside the US, but as far as I can tell - we shouldn't be able to use 3G in the US, at least on T-Mobile's network, since they're using 1700 mhz band/AWS range, and the 2100 mhz band used elsewhere is not compatible. I THINK. I'm honestly just learning about this sort of thing now as I go, despite having had my Uni for a while and having known about T-Mobile rolling out 3G coverage for some time.

Could you give some more details on this?
Please correct me if I am wrong, but I think the deal is basically, as postulated by orb3000 - no 3G for US Universal users.

I was told by a T-Mobile rep on the phone that if I can connect to 1700 or 2100 mhz band, I should be able to use 3G... So I wonder... Huh.

So can you confirm if T-Mobile uses 1700/2100 as:
1700 down/2100 up
1700 voice/2100 data
1700 OR 2100?
Because I've seen a lot of different things saying different things. =/
Incidentally, please go to http://www.dslreports.com/mspeed and tell me what speed you get on your phone.

T-Mobile uses 1700 AND 2100 mhz bands....sent and recieved data ARE NOT SPLIT between the two bands.....voice and data ARE NOT split between bands.
Ill check my speed tonight when I get off work....
I can see the difference between 3G and GPRS though. I have a HTC Wizard that supports EDGE, and my Imate JasJar is only slightly faster than my Wizard. My girlfriend has the new Mobile G1 and her 3G speed run rings around my Imate JasJar internet speed this is probably so because the age of our Universals.

I have a Qtek 9000 and am waiting for the 3G coverage for my area with T-Mobile which should be in the spring of 2009. Over the past few years I have done a great deal of research on this and have also spoken to very knowledgeable Tier 3 T-Mobile staff that are familiar with this and this is what they told me. The universal will work on the 2100 frequency with T-Mobile. T-Mobile will be using the 1700 & 2100 frequency bands in the U.S. for 3G frequency. I know when I visited my relatives in Germany in 2004 Year in the summer as I can speak, read & write German as good as English even though I am first generation in the U.S. which I visit my relatives every 5 years and due to visit them in the summer of 2009 year. The 2100 band was already released in the spring of 2004 year in Germany. But since T-Mobile has only certain cities available that have the 3G coverage in the U.S. which is spotty at this time. Since the T-Mobile G1 was deployed in October this should make the rollout faster in the U.S. for the 1700 & 2100 mhz frequency. Can you please confirm on your I-mate Jasjar on what your 3G speeds are? They should be at least 384 k.p.s. It is also nice to know that the send & receive data, voice & data are not slit between the two bands of 1700 & 2100 mhz frequency.

Park and ATLDON, thanks for all the info - this is all very good to know, and great news for US Universal users. I'll just have to wait for 3G 2100 to be active here in Portland, then.
Oh, and ATLDON - one more question. Under your Phone Settings, where you can select GSM and UMTS band and Network Type, did you set it to Auto, or force UMTs, or did you even change anything?

this is interesting stuff, i just got my jasjar as an anniversary gift from my girlfriend and i love the device however anyone that has used HSDPA which i had on my kaiser before i sold it 500-900k going to GPRS has been something that would make one want to cry, and its good news to hear this because i need some form of high speed again, and i'd like to confirm this working because i am going to get a t-mobile prepaid or flex paid sim ASAP to get this going, i am in new york anyone from around here to confirm 2100Mhz?
also anyone able to do a screenshot ?

Funny, I was just trying to get an answer as to whether or not there was a delay in deploying 3G over 1700 vs 2100 mhz to a given area, and I ended up being told "definitively" that unless my handset is able to connect to both freqs, I would be unable to utilize 3G access. CONFUSION. I think there are some disconnects between staff at the T-Mobile customer support, and I haven't really gotten much further than what I would imagine to be tier-two tech support.
I trust in ATLDON's success story, so... Maybe I'll just have to wait and see.
Do you get a 3G indicator somewhere in the taskbar or system tray when you're connected? And what was the MMS setting you had to change? What server are you using for net access? Do you have the $6/mo T-MobileWeb access or one of the other plans?
Sorry for all the questions, just very curious and hopeful that I would soon be able to really use my Uni.

The 3G indicators don't work on the 6.1 Roms I use. I havent tried any of the WM 5 roms to see if their indicators work
The MMS connect, I had to change it from T-Mobile MMS to the Internet to send/receive multimedia.
I have the 19.99 unlimited data plan.
I use epc.tmobile.com

Are there any other US Uni users in different areas who can report 3G connectivity?
Thus far I've found my own interactions with T-Mobile tech support to be thoroughly useless in getting any sort of details on AWS/3G/2100mhz deployment (maybe I'm just not talking to the right people?)

So, a couple weeks later (and still impatient ) - anyone else in the US with a Universal able to access T-Mobile's 3G network?

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.

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.

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

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..QUOTE]
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.

You got this backwards. Think AM and FM. AM can be picked up much farther away.

My bad, I do that a lot
