Can it be used worldwide?

Hi!Can i use an unlocked hermes,(apart from the tytn),in any country round the world?Anybody tried doing so??Thanks!

No mobile works in every country around the world.

I think that answer is a bit terse. A quad-band phone like the Hermes can be used in virtually any country. Take a look here, and you'll see that with the 850, 900, 1800 & 1900 MHz bands covered there's not many countries you can't get a signal in.

I'm not familiar with Japanese requirements, but while it stands out as having a different set of requirements, I'm reasonably sure the Hermes works there too.
Testing it out in every single country could be a bit of a large proposition though.

So add the countries with 850/1900/2100 UMTS to the GSM list, and you'll have a comprehensive list... and yes, Japan uses 2100 UMTS, so you can add that one, too.

That just leaves the wierd 1700 spectrum .. wonder if any country is running that ..

Not yet and probably not for a few years...

So in short,if i unlock the device,i may be able to use its phone capabilities on any carrier in the whole world,provided the carrier uses one of the 4 bands for communicating.The carrier may be anyone apart from the tmobile,o2,orange,cingular,vodafone?!

Yes ... you can use an unlocked TyTN on any carrier in the world that has one of the 7 bands that TyTN supports (4 GSM + 3 UMTS) ..

Ok thanks...the reason behind that question is that i'm going to Mauritius(a lost island situated in the indian ocean, beside reunion island) for a few weeks..And i wanted to be sure that my unlocked m3100 would work perfectly there...Anyway, thanks for ypur kind support..

Ahha .. Mauritius .. You are lucky my friend .. what a beautiful place from what I have heard .. enjoy your trip ..

Thanks,mauritius,the paradise on earth,here i come!

Update: At the end of Nov 2006 T-Mobile won FCC auctions in 120 US markets for spectrum licenses in the 2100 and 1700 frequency bands. It is reported they will start rolling out service during 2007 (Sources: T-Mobile US Press Releases and Wikipedia). So the answer now appears to be, yes, the 1700 spectrum will be used extensively by T-Mobile USA.
I am not personally aware of any HTC phones which support 1700 yet. I am no engineer, but my assumption is that this could not be done through software upgrades on any existing devices. I imagine it will require different radio hardware. Clarification from the experts on this forum would be much appreciated.

Just a note of caution I've tried to use an unlocked VPA compact III in Barbados on the Bmobile network, but I can't geta signal. If I use a vodafone card I manage to get a signal, so I'm not sure all carriers support this phone.

Yes, a software upgrade cannot physically synthesize circuitry to support the 1700Mhz frequency channel.
Looking at the hermes architecture, their LNA's have just enough frequency coverage to support the 7 bands. So the answer is a concrete no in re: 1700MHz.
It is possible to deisgn an LNA with a larger bandwidth, for example, to cover frequencies from 1500MHZ to 2300MHZ configurable via MEMS capacitors and inductors (I have a PhD student working on this atm, but he is facing the problem of keeping up the gain as well as linearity of the amplifier). Motivation for this: the fewer LNA's the less power a device will consuming yielding greater battery life.
HTC maybe should think about hardware re-configurability as well, but then again, they would like to make their devices obselete ASAP.

NO, you cannot use it worldwide
I could not receive a signal in Brazil with my 8525. Others reported the same problem with the Samsung Blackjack. Cingular has not provided a solution to our problem.
I hope the band select hack that I found on this great XDA forum will let me use my unlocked 8525 in Brazil next time I go in March.
Australia, if I recall, was also a problem for a Blackjack user. See the Blackjack thread on the Cingular forum for details on our tribulations.

I have used my TyTN in the USA, Japan, Taiwan, Thailand, Cambodia, Singapore, Philippines and Hong Kong all with no problems. All locations outside the USA were with pre-paid local SIM cards (except Japan and Taiwan, which were roaming on Cingular).
Are the people having problems using a Cingular SIM (and roaming), or using a local pre-paid card?

I got full coverage in the Geylang District in Singapore. full bars.

Am I right to understand that an 8525 purchased from Cingular is locked to Cingular and in order to use in another country it would need to be unlocked prior to inserting another sim card? Would I simply ask Cingular to provide the unlock code for such use?

I'm having a Problem using a local pre-paid SIM card in Barbados, if I Roam on Vodafone which is my original carrier then it's no problem at all

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

HTC HD2 3G Not Detected!!!!!

Hello if someone could help me with my 3G connection inquiry, I would greatly appreciate it.
I bought this phone unlocked from Hong Kong and brought it back to Canada. But the 3G connection through Rogers won't work. I am able to connect to edge (When i pop in my sisters sim card which has a data plan, as my sim card currently does not have a data plan).
I talked to Rogers and they said that everything is compatable (After mentioning the phone frequencies and speed capabilities) and that the only reason 3G isnt working is that I have not configured my phone properly for 3G and at this moment it is configured for 2G (Edge).
I then contacted HTC and they said the reason was because "for the Rogers network, their 3G signal is operated on the 850/1900 MHZ band and the Touch HD2 operates on the 900/2100 MHZ band." Could this be the reason? Will i never taste the pleasures of a 3G connection?
PLEASE HELP!!

since you have bought it in hongkong most probably you have the asian version. It comes with 900/2100 MHZ bands and as you mentioned ROger needs 850/1900 frequency.
You could also get Telstra version from Australia and unlock it as it has 850/1900 frquency so that you could get 3g. But not possible on the one you already have.

Yea its the frequencies. When I take my phones abroad, I always check what frequencies the country has. If the frequencies don't match, the phone won't work in terms of placing calls, 3G etc.

is there a way to unlock ?

There is no software that can get around this "problem"
It is purely a hardware limitation.

perhaps with flashing radio but i'm not shure

Nope, it still will not support the correct bands that he needs
This is a completely hardware related problem

Does Tmobile (US) HD2 work in China?

Hi, all,
I travel between China and US often. I am thinking about buying TMO(US) HD2, since it is a lot cheaper than anywhere else I have seen. Also, It comes with other goodies and full warranty. My concern is that will the phone work in China under 3G? I know there is iPhone in China (China Unicom). I think it operates on AT&T 3G (WCDMA). China Mobile uses TD-SCDMA. 3G on that is out of the question. If I don't get 3G, I guess EDGE is ok, I don't even think I get that speed on China Mobile. Don't really want to put close to $500 for an experiment.
Any answers would be greatly appreciated...
Perry

The USA T Mobile radio uses quad band (850/900/1800/1900) for the GSM freq. The 3G freq is 1700/2100.
China GSM uses 900/1800 for GSM and 3G. So, you will get EDGE speed but not 3G.
On a different note, you would be able to get 3G in Korea and Japan because they use 2100. You have to make sure that Auto is selected for you Network Type and Band Freq on the Band page for that to happen.

I'm thinking about getting an HD2 to use here in Japan.
It feels like a gamble. I have a SoftBank X01T and I've been using custom English roms. (I know the AP and password) (The Sim is with SoftBank).
I'm hoping it's possible to just get an HD2, pop the sim card in - set the AP and password as usual and it should be ok?
Any thoughts please.
Plus anything to backup the 3G working in Japan.
Thanks if you can advise.

[Q] is it possible to convert International to NAM ?

Ok so I have to admit that in the middle of my excitement, I overlooked this and bought an HTC Legend International version from Amazon (http://www.amazon.com/gp/product/B0035ER8OO/ref=oss_product)
Where I live, we get 3G 850Mhz (similar to AT&T), but this phone being international and all only supports 3G on 900/2100 Mhz. I do get GSM 850 with super-slow Edge connection, but no 3G, which is like having a hot woman and not being able to "do" her.
My question is, can the radio on this phone be flashed to converto to 3G 850 (NAM Version) or is it my only option to sell this phone immediately?

You may only get faster GPRS/Edge speed by playing with some build.prop settings but that's about it AFAIK

Thanks for the reply, I just put it up for sale on my facebook and local market with the excuse that I bought it for my wife and she thinks is too complex and prefers Blackberry. hopefully someone will buy it and I can order me a new phone with the right 3G band support .
