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.

can the CINGULAR 8525 use HSDPA 2100

I read on GSMARENA that the 8525 us version is only 850 and 1900. is that true and is there any soft hack to put 2100 (I live in Brazil and 3g with TIM is 2100 here)

I think you read that wrong.
The 8525 already supports the 2100 frequency out of the box. Thats why it works in countries like Japan.
I belive what you were reading was the US (AT&T) uses 850/1900 for its network. However the phone itself supports GSM 850 / GSM 900 / GSM 1800 / GSM 1900 / WCDMA 850 / WCDMA 1900 / WCDMA 2100

Appears to be different version for US

It says (and I copy and paste)
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
HSDPA 850 / 1900 - US version
Some phones have different versions for US

Every Cingular 8525, Cingular 8500 and ATT 8525 I've ever used (Mine and friends and work) have ALL supported the 2100 MHZ band.
I even searched the ATT HTC forums and all the results I've saw showed people using their 8525 in places like Japan that uses the 2100 freq without any problems. And these were all US versions.

Was in Japan last week & had no problems using my 8525 over there.

I used mine in 2100, and HSDPA work OK

Thanks for your answer

Thats the kind of answer I like to see here. Clear and objective.
(I would take of my hat to you but then it would show my bald head)

Any idea on how to get the HSDPA to work on the Cingular 8525? I have the AT&T Tilt and used the Kaiser Tweak and works perfectly. Co-worker has the 8525 but not showing up. We work about 300 feet from a cingular tower that has HSDPA because my Tilt picks it up but not his 8525.
Is there any type of setting that must be done for this to work like I had to do the Kaiser Tweak?
Thanks,
Flandrel

In New York and 3G/WCDMA UMTS doesnt find signal... please help

I am very confused. my phone does not connect to 3g AT ALL.I have tmobile in usa in new york and I tried changing the settings in my phone options from gsm to wcdma and default the umts to 2100 and my phone stays on searching for service.. Can anyone help me out?? I want to be at 3g speeds not gprs... tmobile gprs is way too slow and it only works on GSM mode.. How do i connect to 3g with this phone? I updated my radio from 1.15 to 1.18 and I am getting the same exact results. This thing is driving me crazy, it just doesnt make sense.. someone please help me out, id greatly appreciate it
EDIT: Nevermind, i realized all of us HTC UNIVERSAL users are completely screwd because USA Supports only 1700-1900 Bands and the HTC UNIVERSAL only uses 2100mhz Bands.. NO 3G HTC UNIVERSAL IN THE USA. THIS SO SUCKS MAN.. =.-(

From what I have read on the Internet and speaking to a well knowledged person at a T-Mobile store the 1700 & 2100 AWS will be deployed in the United States. This is the same technology used in Europe on the 2100 UMTS WCDMA frequency. The T-Mobile representative had mentioned that New York City was using the 1700 AWS UMTS Frequency for voice & data but will also be deploying the 2100 Frequency later this year or early next year which last year T-Mobile was the highest bidder at the AWS auction and had also purchased this frequency but which originally the 2100 frequency was used by the government only for satellite transmission. Once the 2100 Frequency is deployed your radio will search for and if available find the 2100 frequency and connect to it automatically. You do not have to get a different sim card like AT&T which you have to purchase a 3G sim card. I am also anxious to get that frequency but is not yet available in my area. The best radio version is 1.15.

very very interesting... i cant wait till that comes then..

I disagree, usually with most software the higher the version number the better, and there is no evidence that 1.18 is any worse than 1.15 at all. I've been using 1.18 for around 1 year with no problems.

I was use a lot of times for search wcdma network name in shanghai , beijing or hongkong.
first , you need insert USIM card ,not SIM card to handset.USIM card is Support reg to WCDMA or GSM network.

You're post has been the most insightful writeup in regards to T-mobile US 3G I've ever came across, Many thanks!

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.
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

3g in Argentina

Hi,
I'm from Switzerland and I've to buy a new phone for my father that lives in argentina... the problem is that here the 3g frequencies standard for phones are 900 & 2100...
What are in argentina, I've seen that are 850 and 1900....
The only phone I've found for acceptable price is the samsung galaxy S that has 900/1900/2100 (no 850mhz!!!)... will this phone work???
last question is... if i've only quadband gsm and 900/2100 3g can I use internet also with slow velocity?

help please

nothing for now?

Motorola Defy ?
3G Network HSDPA 900 / 2100
HSDPA 1700 / 2100 or HSDPA 850 / 1900

Have a look at GSMArena Phone Finder - here you can tick the frequencies you like. The only phones that offer quadband UMTS for now are latest Nokias (for example C7, E6, X3-02) and Samsung Galaxy SII. If you buy a quadband GSM and 900/2100 UMTS phone you would be able to use only GSM in Argentina.
