GSM from Tri-band to Quad-band,

Hi, can I change touch dual the GSM from Tri-band to Quad-band,
for the better reception in USA.
I know the touch can do that, Thank

Now that its going to be available in the US with quad band, does it mean tri band niki can be changed to quad band?

I would like to know this too

It could be possible, but the RF chipset could be totally different on the two models.
There wouldn't be much of a reason for HTC to restrict the current tri band duals with the way the various operators have deals with other overseas operators.

You would think they would have designed, developed the radio chip long ago, and the new edition would only contain software changes to the OS, and Hardware soft updates

--bump--
I too would like to know if this is possible. The best buy website has a touch dual listed with 850. I called their customer support and they couldn't give me any information on release date or even a model number. Will the US version of the dual have 850? I want to know if I can get this $500 phone to work here (area code 318 with ATT) on just the 1900 band or do I need the 850 band for better reception. Any advice would be helpful. Thanks in advance.

Any luck? I would like to upgrade to the quad band

theres only one version of the dual that is quad band and that is the US version being sold by BEST BUY.

Thanks for the reply I figured I was out of luck, so I ordered the us version yesterday.
Bought the triband Dual but, soon figured out that it doesnt work well in the states.
I thought I would give it a go.
Thanks

Was working on 850MHZ than....
My HTC touch was working on 850 MHZ than I had a tech at my provider's, setting up my internet.
Since that moment it does not work anymore:
Getting the signal but not able to make calls or receive calls.
The guy tried to fix it. It worked for a couple of calls and than stopped working.
Back to the tech, he told me it s because of the 850mhz on which they operate.
He said that even if it was working fine, it wasn't meant for their network (850 MHZ).
Should I believe him?
(the phone works fine with 1900MHZ band from another company)
How can I fix this?

wish there was a radio upgrade like the latest for the diamond that enabled the 850 band

AT&T Vogue???

I cant find any relevant posts, so...
Can I buy a Sprint Touch, unlock it, and use it on AT&T service? Sprint has no service where I live, so I'm stuck with AT&T for the meantime thanx in advance for any help

no...sprint uses CDMA technology and ATT uses GSM... you can purchase a GSM version of the Touch (called the HTC Touch) which "technically" doesn't have the 850 mhz band (which offers better signal reception); however, there are may HTC Touch users that say the phone works very well with ATT. the implication is that the phone has 850 mhz band but it's not advertised.

I appreciate the response! Well crap! I need the 850mhz, cause that's what's available where I live. I'll have to find another way. Thanks again

Well, if money is no object, you can try the Touch Cruise:
http://www.htc.com/product/03-product_htctouch_cruise.htm
It's a bit different, but apparently the newest model, and it has 850 and HSDPA

i'm using the Orbit 2 which is different version of the Touch Cruise. you might want to read some of the HTC Touch threads on HowardForums.com for feedback on the HTC Touch being used on ATT. there are lots of people over there that are using the phone on ATT.

why not get the tilt?
I was wondering why not just sign a new contract and get the tilt. It's quad band and I have seen some sell on craigslists for as little as 300 for a used one with no contract. You could probably get one cheaper with a contract. plus you get a tilting screen, a slide out keyboard and built in gps receiver. Just a thought. Tilt aka HTC Kaiser. You can find the info on this website in the Kaiser section. It is heavier though.

Topaz for US UMTS Band? - Might not happen (see post #11)

Is Topaz is available for sale for US UMTS bands? In all the online shops i see this phone only with UMTS 900 and 2100. I am planning to buy one but i dont see one with UMTS 850 and 1900.

I'm still waiting for 850mhz. It clearly isn't out yet.

3G for AT&T US?
Does anyone have any info on whether and if yes, when, the Topaz will be offered with the US 3G bands??

I'm Not sure which bands AT&T uses seeing I'm with T-mobile but here are the bands the phone has.
GSM(900+1800)+UMTS(900+2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
3G on T-mobile does not work but I don't mind because Edge is fast enough for me. I had faster loading times on Webpages yesterday than my freind with a touch pro on Sprint's 3G. So ya. I don't know anyone with AT&T or else I'd throw the SIM in and try it.

If that is correct -----the UMTS 1900+850 part----- then those are the AT&T 3G frequencies. Where did you see those bands?

If you go to Settings/All Settings/Personal/Phone/Click on the Band Tab it is under the Selet your GSM/UMTS band.
If I go to the mall today I will stop by the AT&T store and see if someone there is willing to insert their SIM in it to see if it gets 3G. If so I will post up.

That is great!! If you can check and let us know that would be a great help!!
Is UMTS band availability is all software/firmware related.. i thought thats hardware.

having those band settings does not mean it will work on US 3G networks. for example, the UK Touch HD (from the UK) has the same band listings as above but the radio doesn't support at&t's 3G bands (850/1900). it will work for voice and EDGE internet speeds without issue. it's a hardare limitation. 3 months after releasing the UK HD, HTC released a Telstra (Australia) version of the Touch HD that had the same band listings (as above) that works with 850 3G bands. Since Telstra uses the same 850 3G band that at&t uses, the Telstra HD can access at&t's 3G network. i'm speaking from fact because i have both the UK and Telstra HD versions.
HTC is known for relasing the same device with radio limitations: they did it with the Diamond, Touch Pro, Touch HD and they're doing it for the Diamond 2. if you want US 3G access - via at&t - on the Diamond 2 you'll have to wait until HTC releases the US 3G version.

This clarifies. Thanks friend. Do you aware of any news on when HTC might release the D2 for US?

verified today.... does not work on at&t. the guys at the store said that it is 1900/900 band not 850. 850od the 2g frequency. havnt checked on how correct they are on this but a quick google search will verify the frequencies.

A reply from HTC
See the reply from them below. HTC did not mention about any carrier like ATT or T-Mobile asked for this phone.. looks like this phone will never make it to US? That is a Bad news......

Hello Sundaram,
Thank you for your inquiry about the Touch Diamond 2.
We appreciate your inquiry about one of our new phones. Unfortunately, we do not remake our phones to work on a specific network, such as the AT&T 1900 band width, unless that carrier request us to make them that exact phone. If you do buy the Touch Diamond 2, we cannot guarantee 3G service since AT&T 3G band is 1900 while the Touch Diamond 2's 3G band is 2100.
I hope we have answered your question in detail. Feel free to contact us again if you have any further questions.
Thanks for contacting HTC,

Subject: HTC Diamond2
Dear Sir/Madam,
I own a HTC TyTn II and HTC Fuze (ATT) and now planning to upgrade my smart phone to HTC Diamond 2. I am really impressed with this phone and ready to purchase one. I live in USA and have a question about the 3G band availability of HTC Diamond 2. The phone is available in many online stores but they all have a specification like below.
Operating Frequency:
HSDPA/WCDMA: Europe/Asia: 900/2100 MHz
Does this mean that I cannot use this phone for ATT 3G networks in USA? Does HTC manufacture HTC Diamond 2 for US 3G band which I believe are 850/1900 MHz?
Is there any planned date of releasing HTC Diamond2 for ATT 3G networks? I appreciate your response.
Thanks

The Diamond 2 IS COMING TO THE US WITH 3G SUPPORT in a few months. Stop this nonsense please.

What makes you to visit this topic and through a comment like this? I was not asking "you" this.
Besides, I am not working at ATT or HTC but trying to see if any other member of this forum has any news about this. If you dont like this topic just dont visit it and try to change your attitude. Otherwise you will become a great looser (i guess you already are).

Clearly that is a pretty general statement that I believe most of us find to be true. That being said, do you have any more insight?

If it's coming to the US with 3G I would just assume that it would hit Sprint first so still no luck for AT&T. Didn't ATT just get the FUZE in like Dec? Anyways the phone most likely to hit US carriers is The Pro2. Americans generaly (IMO) like a full Hard qwerty keyboard.

This was floating around a few months ago

Shows the topaz going to AT&T. I'm not sure how valid it is though, but it's something to cling to

Even if it does come to AT&T, I hope we see the unlocked version well before. HTC used to be the one company we could count on to deliver US 3G on newer releases. Now we seem to be stuck playing the waiting game. The odd thing is they released the TYTN and such when the 3G network was barely rolled out, now that it at least covers all major cities, we cannot get any love.

I have been waiting a long time for this
Word is "HTC Topaz 210" (AT&T warhawk) will be released next month /(october) with the 850mHz UMTS "7201" chip (instead of the "7200" 900/2100 UMTS chip)
It will also be slightly smaller (1 mm less longer and wider)
I may drop around here if HTC beats the drum with this one
PS: sorry for resurrecting an ole thread, but we american users really miss good HTC 850mHz phones

I too am waiting for the US version of D2. gtrab, where did yo uget the info that US D2 will be slightly smaller. The latest info was from BG but I don't remember him mentioning any other spec except the obvious 850/1900 implementation.

is there any way to buy a tmobile us hd2?

i am stay in england. i want to buy the new hd2.
thx

Do yu really want a phone that is bigger than the one you'd get locally, and won't be able to use 3G?

I agree with the lack of 3G being an issue, but I've gotta have a great big LOL at the size comment. LOL mate - funny.

I've been meaning to ask this question. So how much difference is the size? I heard it was not very noticable. I saw a link that was posted to a blog somewhere. I'm not sure how credible that source is. Is it taller or wider? By how much?

i just know the euro version is 448MB RAM + 512MB ROM but, t-mobile us is 576MB RAM + 1GB ROM.

It's 1.5mm taller - that's all (EU HD2 is 120.5mm and the HD2b is 122mm tall).

The EU version also has 576MB RAM. It's just the ROM that's different.

It is 1.5mm taller. I'm not sure that it will not work on 3G in UK: from the specs it seems that it DOES support 2100MHz UMTS (band I) so it should work in Europe. Notice that the G1 had the same specs and many users reported success when used in Europe.

In that case the European ones should have worked in the US (still talking of 3G of course), but we know they don't...

No why should they? It is very simple to understand how 3G works in different place and with different phones:
T-mobile 3G network operates on UMTS band IV (i.e. 1700 MHz upload and 2100 Mhz download).
ATT operates on UMTS bands II and V (1900 MHz and 850 MHz).
Most European networks are UMTS band I (2100 MHz) and sometimes band VIII (900 MHz).
Now, the specs of TOMUS version of HD2 says that it works BOTH on band I and band IV. That is why it can work both on US T-mobile network and in Europe. It cannot work on the ATT 3G network though.
The EU version of HD2 works on bands I and VIII so it cannot work on either of US 3G networks.

OK, hadn't seen that.

Here is the relevant part from the TMOUS HD2 specs:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100).
I'm living in US now but I'll move to Switzerland within a few months. I have ordered this phone for myself since I want to use in Europe.
Btw kilrah, maybe when I arrive in Zurich (that's where I'm going to live) I'll come and visit you

Unlocked TMOUS For Sale
I have one unlocked that I might sell if TMobile decides to charge me a restocking fee to return it. Given the demand I was thinking of selling it for $550usd.

Unlocking 3G on HTC Desire

I purchased an HTC Desire to use with my AT&T service. My Desire is GSM/WCDMA and not GSM/UMTS. Meaning, that my Desire can not run on anything but EDGE. I spoke with a rep at HTC and he let me know that there may be an APP to unlock the 3G service... Does anyone have any information on this?
Thank you kindly in advance...
~HR

isn't WCDMA = UMTS?

That's what I thought too, but the HTC rep, let me know that I can only unlock 3G with an App. That because I have an import and it's not currently available in the U.S. I would need to find this app and unlock my 3G service. The Desire wont pick up AT&T's 3G...

Yes........

I think it might be a frequency issue.
As far as I'm aware there are two models of Desire - A8181 and A8183.
In Australia, the model is the A8183 which provides WCDMA/UMTS at 850 and 2100 mhz. I think the A8181 operates at 900 and 2100 mhz.
If you imported from anywhere else other than Australia you'll most likely have a model A8181.
What frequency is AT&T 3g?

I do have an A8181. AT&T currently uses 850 and 1900 mhz...
Do you think there is a fix for this like the HTC rep mentioned?

AT&T uses 850/2100 like Telstra does in AU.
If you have the A8181 you are stuck with 900/2100. I think it's a hardware thing so an app probably wont help, not 100% sure about that though.

You bought the wrong phone ?(A8181)! As has been previously mentioned, you need an Australian Telstra Desire (A8183) to support AT&Ts 3G.
There is nothing that can be done about this because the hardware is different. You should sell your A8181 and buy an A8183.

Sorry to say , but I don't think so. the differences are in the hardware, not software.
You could always keep your device and change carrier? I presume someone in your area might use 2100 mhz??

Unfortunately not - the only other major GSM operator in the US is T-Mobile, and they use a split band of 1700/2100 and requires support for both to work.

Bugger! And I thought Australia had crappy providers
@Hugo - good luck with your sale. The device is incredibly popular in Europe, so eBay might be your best friend for a buyer.
