Hello everyone! I'm wondering will this device work with AT&T service since it's just a triband phone, and, afaik, AT&T uses 850MHz as their primary frequency for GSM calls (depends on location) in NYC area.
Coverage maps are here:
http://www.gsmworld.com/roaming/gsminfo/cou_us.shtml
Specifically the 1900Mhz map is here and you can zoom in to your area and see: http://www.gsmworld.com/cgi-bin/ni_map.pl?cc=us&net=be
[You can probably also find them some place on the AT&T website.]
Be aware tho that the diamond only does 3G at 900/2100, but AT&T use 850/1900. That means you won't be able to use 3G capabilities on AT&T anywhere.
I would either wait for the american version, or buy the 2G one they're selling in india for ~200$ less.
Thanks, man! Maybe i'll look at T-Mobile plans, looks like device will work with them
Well looking at the page it looks like T-Mobile have even less 1900 coverage (GSM). I don't know their current 3G situation, but they will be/are using 1700Mhz for 3G, which the diamond can't handle either
I couldn't help myself. This phone seems perfect so i ordered a diamond that will arrive tommorow. Now my question is if anyone thinks the bands for US are present and need to be unlocked or if this will end up on ebay . Thanks!
There's several topics about it there.
You won't get any 3G in the US with it, and you'll only be able to use the 1900 band for voice/GPRS/EDGE.
Actually you are incorrect. 1900 Mhz is supported w/3G w/AT&T in certain areas. Unfortunately my Diamond is not even getting an EDGE connection. From what I am hearing the Diamond is only supporting 2100Mhz frequency w/3G according to HTC. Which to me makes no sense.. I am blogging my experience with it as it is the first production unit in the USA.
You just said i was incorrect and correct in the same paragraph lol
This is where all the confusion starts.. For GSM/GPRS/EDGE it does 900/1800/1900 MHz - only 1900 would work in the US. For UMTS (3G) it only does 900/2100 - neither of these frequencies are used in the US.
The protocols and modulation used are completly different for GSM/GPRS/EDGE vs UMTS. The dispersal of uplink and downlink frequencies is completly different. Just because it can do 1900 for GSM doesnt mean it should do 1900 UMTS.

So why wouldnt I get Edge? I have had triband phones before i.e HTC 8525 that worked ?

You should get edge. Edge is an extention of GPRS but requires a different BTS (radio tower) setup. Its possible you don't have a strong enough signal, but it sounds like your confident you should have edge in that area.
The only thing i can suggest it to try in a different area - like the centre of town. Also, confirm your APN is setup corectly, the [G] may just be telling you GPRS is available, but not that you can attach.
I know with my elfin it takes a little stronger signal to initiate the Edge icon the first time (ie. after a hard reset). I can't get an edge signal inside my office but once I walk outside for a minute or two, bam I have it. Then when I go inside I still have it.

Diamond had UMTS(2100)+GSM(900+1800),UMTS(850+1900)+GSM(850+1900),UMTS(800+2100),UMTS(850+2100)+GSM(900+1800),UMTS(850)+GSM(900+1800) and UMTS(1700) depend what rom you had in your Diamond and where you bought your Diamond , At&T should be show 3G in US and T-mobile used 3G (1700 Mhz) in New York area
The platform in the phone can support all those bands, so you might be able to see them (like in the test rom) but the antennas are not there. So you won't actually be able to pick up a signal.

I guess all of us US early adopters must hope the hardware is there and can be enabled with a future flash.
T-mobile in the US uses 1900mhz for GSM/Edge and only has 3g in NYC, so I'm figuring that it's a cool stop-gap device until something is available for T-mobile 3G.
so anyone have the rom that had thoose bands....
confused
so im a little confused.... If I buy a diamond on ebay, it wont work in the US? or 3g just wont work? does the diamond accept a sim card?
On AT&T it will give you only GPRS! On Tmobile (NEW) it shows EDGE!! I dont understand this at all!

Voice and EDGE will work just fine as long as you are in a major area that uses 1900 band. You might have weak or no signal when you are in smaller rural areas since those usually extend into the 850 band.
You will not be able to use 3G since the Diamond only supports 900/2100, neither of which are used by AT&T
It looks like if you have ATT you are hosed for both voice and data, as most of ATT voice and data (Edge) is 850mhz. Most if not all of T-mobile voice-data-Edge is 1900mhz so you will have at least Edge. If you're looking for 3g data you're SOL until the US version of the diamond is released.
this fn blows htc has really screwed us here in usa...i was willing to spend 800 for this device and htc doesnt even see this? by the time it comes out here in quadband ...the x1 will be out and not mention the 3g iphone...oh well

We will get the diamond, have to wait for the US version that does the different bands.... wich leads me to my next question. What carrier do you think will get the diamond??? AT&T seems to get all the cool stuff.

I don't think HTC cares about America too much any more because it's iPhone territory. As they haven't used their own branding until recently, I think HTC are looking to gain market control and loyalty, and that's easiest where the iPhone hasn't been a huge success.

Again, HTC seem to like doing exactly what Apple are not doing, so they may go for multiple carriers. As far as I'm aware the Touch Diamond, and its branded versions, are launching on every network in the UK. That's the complete opposite of Apple's 'one network per country' policy, and they consequently seem to have dropped it (for example, in Italy).
AGREED 100%!! I have been saying this on my podcast for quite a while.. It is a huge mistake. I am now saying since I just received my Diamond that I took one for the team.. I will post my review as the days go by...
SIGHHHH

I saw the following url
http://pdadb.net/index.php?m=specs&id=1387
on PDAdb listed as new for Kaiser 140, describing what in essence is the existing Kaiser. I searched this forum for any relevant terms and cannot find anything about it. Is this a new version? Has anybody heard of it?
It is also posted on the main front page of PDAdb.net:
http://pdadb.net/index.php?m=main
You'd probably get more of a response if you posted this in Kaiser general, especially since this isn't software related...
Added UMTS 1700?
That must mean it's for T-Mobile US. I heard T-Mobile was supposed to be getting the Kaiser. and their 3G is 1700 band(in case you didn't already know).
I wonder if that means us AT&T people could buy one and use it roaming on TMO's 3g network.
My apologies for posting in the wrong place! I usually check only the software section, it did not occur to me.
As for cellular networks, they llist GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1700, UMTS1900, UMTS2100.

I wonder if this means it has an updated hardware radio transceiver, and the rest of us are out of luck?
Would this mean there is no way to actually get 1700 through a radio flash like how Emobile's radio works on the current Kaiser without locking it to 1700MHz only, and flashing a Kaiser radio to Emobile won't give it 850/1900/2100?
I don't know, but I'd sure like to see a date on its availability and make sure those specs are real-- I travel a lot to Japan, and I want to switch to T-Mobile here in the states the second 3G gets turned on.
See, I'm with Sprint now but my contract is up September 1st. I'm supposed to be back in Japan sometime in October. My plan was to get the unlocked unbranded TYTN II from NewEgg and put it on T-mobile's flex pay plan until I leave. While I wouldn't have access to the 3G bands, T-Mo gives access to Wi-fi hotspots if you have a certain data plan, and I also have AT&T DSL service-- that gives me access to AT&T's Wi-Fi spots already. So I'm pretty much covered in most places if I need a faster conncection than EDGE.
In Japan, I'd just go with Softbank or Docomo--whichever is easiest to hook up the TYTN II to and keep SMS,MMS, and Internet to.
But after reading Emobile's plans on their site along with knowing T-Mobile USA will flip the switch on 3G on 1700MHz here in Atlanta soon... I may wait.
So will this actually support quad-band GSM/EDGE(850, 900, 1800, 1900) and quad-band HSDPA 3G (850,1900,1700,2100)?

Softbank. They're the only ones that support SIMs for rental. So so rates, but you could try to negotiate to a flat-rate plan.
Otherwise, you need to do full-contract w new phone, pull the sim, and then use it in the Kaiser. But why, since Japanese phones are so much better when you're there.
Hi everyone--
I have an unmodded, "unlocked" at&t tilt that has a t-mobile gsm sim chip in it. I'm still running the WM6 that came in it, and can't seem to get access to the 3G speeds I know this thing is capable of. I've tried numerous software apps to "force" the phone to go 3G, to no avail. T-Mobile customer "support"--HAA! tells me I need a t-mobile phone to be able to take advantage of the 3G speeds. Needles to say, I feel this is a bunch of malarkey. T-Mobile put out this phone, did they not, and called it the "MDA Vario III"? Is there a rom for the mda that I could flash this thing with so I could get the 3G speeds? Or another rom perhaps? Any suggestions would be most appreciated. Thanks!

Unfortunately, the malarkey is the truth! Because T-Mobile runs its 3G network on a different band than the Tilt is capable of! Sorry, this also effects me as I am a T-Mobile customer using a Tilt as well! My advice is to use Opera mini 4.2 for your internet browsing it is very fast on the Edge network!
The T-Mobile you refer to is European
It does not run on the same 3G as the US T-Mobile. The US T-Mobile uses 1700 Mhz and 2100 Mhz, I believe. The Tilt does not use the 1700 Mhz band. There was a rumor going around that there would be a new version of the Kaiser (KAIS140) that would use the US T-Mobile 3G bands but it was never released for sale. I don't think it will since it is pretty much at the end of the life cycle of the phone. They (HTC) have moved on to newer models with more features. If you would like to use the US 3G and live in an area with 3G, The T-Mobile G1 (HTC Dream) uses T-Mo 3G and has its own section on this forum.
bleh. newer models should still freaking tilt. that is the coolest thing about this phone. and it's pretty solid construction. my friend has had his over a year and its still going strong.

I thought the Tilt accessed 3G through it's tri band frequencies 850/1900/2100Mhz so that it could connect to most 3G networks worldwide, making it a world business tool for users?

True but T-Mobile uses the 1700 for upload and 2100 for download. ATT uses 1900 for both.
I have recently buyed to a friend this phone, and I can't connect to my provider 3G network. Reading, I saw that it is because I have X1i, and I need X1a (I live in Argentina, South America).
Well, is possible to turn my X1i to X1a?
Please help!
P.D.: Sorry for my English.
Sorry, I don't think you can do that, since this is a hardware issue....But, I'm not too sure.

You just need to flash a NAM (North American) ROM if you want to change it to X1A. You can check on the ROM section of this forum.

no..
its a chipset issue, there is nothing you can do.
^^^ what he said....
there is no way, I sold my X1i and bought an X1a because I need my HSDPA.
The slower camera framerate doesn't make a diff, I don't take videos with my phone anyways.
what is the difference between Xi1 an X1a
and which one is the latest ?
Few Weeks Back I purchased X1i
and change the ROM to ENERGY ROM .. which was the best Stable ROM SO far.
please suggest
"what is the difference between Xi1 an X1a

the cpu is the difference
non of them are the latests
x1i use qualcomm MSM7200a
which support the frequencies used outside of usa and
support 30fps video capture which because of a lawsuit from broadcomm
qualcomm can't offer in usa
x1a use qualcomm MSM7201A
which support the frequencies used inside of usa and
don't support 30fps video capture which because of a lawsuit from broadcomm
qualcomm can't offer in usa
I was just in the USA and I have an X1i. I could make calls just fine with it. If I have it correctly, the only difference is in 3G networks. The x1i uses UMTS 900MHz (amongst others) while in America (not sure if just north or both north and south America) they use the 850MHz band (amongst others). This, however, is a hardware issue that you cannot change.
Luckily, you'll still be able to use the other 3G bands, so you should still be able to get on 3G. Plus, both the X1i and X1a have the same quad band GSM Frequencies that means they are both capable of working on any 2G network in the world.
i have an X1i and live in the united states. i can never, ever connect to 3G, only Edge or HSDPA can be connected to. really it's fine, i'm on HSDPA the majority of the time, especially since i live and work in Los Angeles. and HSDPA is always blazing fast for me, especially at full reception......
I have X1i in Canada. Reflashing US rom makes it reports X1a, but 3G is still not available.

HSDPA is 3g: GPRS is 2G, EDGE is improved 2G; UMTS is 3G and HSDPA is improved 3G.
X1a is 850/1900/2100 Mhz 3G, AT&T uses both 850 and 1900. X1i uses 900/1900/2100 3G.
This means if you are on AT&T you may not get 3G with X1i (depending on the frequencies in your area). If you are on T-Mobile in U.S. then it doesn't matter because they use 1700Mhz 3G and neither X1i or X1a will work on 3G, and they will perform equally well (except for the video framerate issue which has been discussed earlier in this thread).
If you are not in U.S. or Australia (They use 850Mhz also) than get X1i. If you want to be sure you will get 3G service in U.S. on AT&T than get X1a. I think Australian providers all use NextG which is 850Mhz so they will also use X1a.
This is HARDWARE difference. Changing software/ROM will NOT change these frequency differences.
I hope this ends this thread because this has been covered many times in many places, both inside and outside of XDA-Developers.

yes i thought so, that's why i'm always confused as to how i can lock into HSDPA but never 3G. which is fine! it's just that i know i can get 3G in some areas i can't get HSDPA and can only get Edge, which is major slowage action...
