UMTS specs - Tilt, TyTN II, MDA Vario III General

Kaiser specs indicate both 2100 and 1900 UMTS. Expansys site notes only 2100 UK UMTS will be supplied as if its one or the other. Does anyone know if there will be an option for both frequencies on same phone?

can anybody clarify this?
Kaiser is 3 band UMTS regardles of region right?
Thanks

the diamond in various conuntrys

hey!
Does anyone know if a diamond bought in the US will work in Israel?
You can go to www.gsmworld.com and then roaming, and then coverage maps. (pick a country)
Here you will see all the various networks in that country and the bands they use. For Israel all networks use 900, 1800 or 2100 (3G).
Since the only diamond you can buy right now uses 900, 1800, 1900 GSM and 900, 2100 3G, it will work perfectly in Israel.
I also want to add that HTC diamonds bought in the US currently is the Europe/Asia version (lacking the 850 band). This will/might change sooner or later.

[Q] Is it possible to get the T Mobile 3G network on an AT&T Tilt 2 device?

I purchased a jailbroken AT&T Tilt 2 online but Im using T Mobile service and I was told that I wouldn't be able to access the T Mobile 3g Network with this device. Could someone verify that this true or if not can someone give me some tips on how to set it up on my device.
Its true, because I have a Tilt 2 unlocked to T-Mobile as well. Is there a way to get 3G speeds, I don't know. But honestly, I've never really noticed a difference. But then again, I do stay away from data heavy sites like Youtube and whatnot.
Hmm, interesting question. The main issue is whether the phone has the right bands to connect to the 3G network in question. Its a hardware issue, and either the phone has the right bands built into the chipset or it doesn't. There is no way to change this with software or by changing settings.
T-Mob uses 1700 and 2100 MHz bands, where ATT uses 850 and 1900 MHz bands. HOWEVER, the ATT branded Tilt 2 also has the 2100 MHz band for international use. If your T-Mob service area is on the 2100 MHz bands, its possible (if you area is on 1700 MHz, its not going to work no matter what). In theory, it SHOULD work. I've made many trips to Japan, which uses 2100 MHZ for both voice and data, and my Tilt 2 (and old Tilt before it) has always worked flawlessly on their networks.
But whether it really works or not, I have no idea. Searching around the net yields some posts on other forums asking the same exact question, with conflicting answers (perhaps somebody on here can enlighten?). My gut says, its either its going to work or its not, it shouldn't take any additional setup. Have you tried it yet?
But in short, it was a mistake to buy the ATT branded version. You should have bought the T-Mob branded Touch Pro 2.
Oh, and wrong subforum, BTW. This has nothing to do with ROM development. This should be in the Touch Pro 2, Tilt 2 General forum. But don't cross post there, the mods will probably move this thread over there for you.

The 2100 MHz band you're referring to is different on both companies' devices. For T-Mobile, 2100MHz is the upload frequency. The worldphone AT&T 2100MHz band is a download frequency. 3G requires 2 frequencies to operate in that manner.
The 2100MHz frequency is accompanied by the 1900MHz frequency for uploads. The AT&T Tilt2 has this frequency set to allow both.
As for Japan, I didn't know they were on the 2100MHz band. I've only every seen a couple of companies on 850, 1500, or 1700 MHz. Where were you that you used 2100MHz or which company? I just like to keep up on where the bands are useful when I make trips to Asia.
Ahh, that's right, I think I did read somewhere, that the 1700/2100 MHz bands are used by T-Mob as download/upload. Not like ATT, where which of the 850,1900 MHz band is used for 3G depends on the geographic location/market.
That means the OP is SOL on getting 3G on the Tilt2, right? He would need BOTH the 1700 and 2100 MHz bands on his phone?
Japan uses 2100 MHz exclusively, standardized nationwide, as far as I know. Same with South Korea (although ATT lists that one carrier in S. Korea also uses CDMA 1800, not sure what the deal with that is).
If the 2100 MHz band on the ATT Tilt 2 is just for download, wouldn't this mean that my phone would not be able to connect to the data network in Japan?

Exactly right. It's a hardware problem, not software as some people think. I seem to answer this question at least once a week here. lol The radio chip is different for each model of the Rhodium. That's one of the differences between the several versions.

It depends on what the network is set up as. 3G worldwide requires two bands to operate because of the bandwidth. GPRS and EDGE only require one. If this 2100 MHz frequency is one of the later, then it will work just fine. If this is a 3G band, then it is VERY likely to be paired with the 1900MHz frequency range. That's on GSM, anyway. I'm not 100% sure what CDMA frequencies are their.

[Q] Bad ESN's and frequencies in Australia

Hi guys,
I've had a look around and can't really find much info on bad ESN's. Most of the questions are resolved with a -"find a carrier who will reflash your phone". The phone I'm looking at is from someone who didn't pay their phone bill. If I import this phone over to Australia - what will a bad ESN do? I'm planning to buy a pre paid SIM card over here, and I'd like to put a basic Gingerbread rom on it.
I can see that a bad ESN means you wouldn't be able to use the phone on the network it was sold on, but if you unlock the phone doesn't that mean you can put on whatever carrier you'd like?
Are there any issues with doing this?
The next part of my question is about the Vibrant. From the info I've found this...
Will My SGH-t959 (Vibrant) Phone Work In Other Countries And How Do I Unlock It?
The SGH-t959 is a quad band dual mode handset. It supports GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 1700, 1900, and 2100 frequencies. There is a possibility the phone may be used with a wireless operator outside the United States however this is not guranteed. The phone has been optimized to work on the intended carrier it was designed for.

From what wikipedia says on Vodafone (in Oz,)
The GSM mobile service on 900 MHz and 1800 MHz covers 94.52% of the country. The 3G 2100 MHz UMTS network is available in metro areas of major cities and some larger regional centres covering 80% of the population. Expansion of the 3G UMTS network using 900 MHz to equal or surpass the GSM coverage is due to be completed by 31 August 2009 [1] [2].

Will this work here? It's seems like it should? (I'm in Melbourne) I'd like the 3g to work for the internet etc.
Thanks guys.
Beumpp....
I can't guarantee it but technically according to the site below, it should work:
http://www.phonearena.com/phones/Samsung-Vibrant_id4747
UMTS[3G] frequencies: 1700/2100, 2100
Optus, vodafone and three use 2100 and 900

[Q] 3G capability of AT&T HD7S in UK

I've just bought a AT&T HD7S off ebay from a US seller and I'm in the UK. It's not until just now that I considered how it might perform in the UK. I see that the AT&T HD7S lists HSDPA: 850/1900 MHz as its 3g frequencies, while the UK HD7 lists HSPA/WCDMA: 900/2100 MHz. Does this mean I won't be able to get 3g signal on UK networks? Does anybody have experience using a AT&T HD7S in the UK?
The HTC Help & How To page lists the following:
What bands does my device support?
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
HSDPA/UMTS: 850/1900/1700(AWS)/1900/2100 MHz
But the Tech Specs page shows this:
UMTS: 1900/850
GSM/GPRS/AT&T: 850/900/1800/1900MHz
So I wonder if the phone actually supports 2100 MHz
And if so, since O2 HSDPA/3G in the UK runs on 900/2100 does this mean that the phone will still get 3G on 2100 MHz, but won't benefit from the 900 MHz band which enables coverage in harder to reach locations.
Secondly, should I only flash AT&T Radios on to this phone or can I flash the Europe modem found here forum.xda-developers.com/wiki/HTC_HD7/Radios ? Might doing so enable the 2100 MHz band which isn't used by AT&T ?

I got mine off ebay too (HD7S AT&T), did u manage to get the 3G working ? Please help me. Have you flashed the Euro radio ?
NO
UMTS: 1900/850
GSM/GPRS/AT&T: 850/900/1800/1900MHz
These are the correct specs.... because there's no 2100MHz band for GSM, the 2100MHz is used by CDMA networks.

[Q] Bands

I need to know if the model that sells tmobile SM-N910TZKETMB uses bands 3g 850 1900 and 4g 700 1700 2100, the information on tmobile's site differs from samsung's site.
Sorry, I have found answer, close it please.
