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
not quite sure how to search this so i guess ill ask (or reask) the question.
1. am i able to reflash my Leo to work with USA ATT 3g bands if a rom ever comes out in the future?
2. can someone confirm to me if step #49 of this tips and tricks thread (http://forum.xda-developers.com/showthread.php?t=583638) and that piece of 3G activation software works and can allow my Leo to work with ATT 3g? (i dont think it does)
thanks!
1. Nope. It's all hardware.
2. See above. Nope.
It's all edge, my friend!

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).
do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.
ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still
T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.
this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."
Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.
thats the link

Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?
* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE
Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?
GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)
For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.
Ok, so I am from California and currently living in the UK... So I have one of the T8585 models... now I know that I am going to lose my 3G connection when I go home so now I am thinking of buying one of the Telstra T9193's to work on home networks (AT&T).... but looking a bit further at the specs of the 9193 the bands for 3G are listed as 850/2100... so does this mean that if I travel back to europe with an american sim in the phone I would still be able to have 3G connectivity? If I wait for the T mobile version which I assume will be 850/1900, if I return to Europe I would have the same problem as going back home with the T8585... Seems ridiculous actually, you should be able to get a phone like this that can maintain connectivity regardless of where you travel. I remember this problem when I first moved over to the UK and had to get a Razor, just for the quad band so I could use it on both sides of the pond... Oh well, would really appreciate it if you guys had any thoughts on these assumptions and maybe shed some light

Hi !
Though the question is quite old, the answer is still interesting for anybody planning to travel or intending to buy an overseas model.
I personnaly had to resign on finding an US T-Mobile HD2 because of the 3G bands problems : our local operator decided to use 2100 MHz to cover the capital, but 900 Mhz for the rest of the island, so I was forced to stick to the European model, in order to be connected where I would need it the most, i.e. in the bush.
I could find an interesting website listing a lot of models, and able to compare them, so just have a look by yourself to this one :
http://pdadb.net/index.php?m=pdacomparer&id1=1783&id2=2062&id3=2059&id4=2192&del_id=2062
As you can see, the only differences (apart from the US T-Mobile 1024 MB ROM I'd dream to have and the 2 mm longer bottom border for the different antenna housing, given that the 576 MB RAM are actually present on all models - it's just a question of flashing the appropriate radio ROM) are the UMTS/HSDPA bands frequencies.
European HD2 (T8585) : 2100 and 900 MHz
Australian (Telstra) HD2 (T9193) : 2100 and 850 MHz
US (T-Mobile) HD2 (T9393) : 2100 and 1700 MHz
The 2100 MHz is common to all of them... Too bad a lot of operators choosed to use the other band.
P.S. : There's even another model, the AT&T HD2, featuring 1900 and 850 MHz UMTS bands, the same size as the European model (but featuring the green and red buttons), but having the 1024 MB ROM...
You're the only person to ever mention a 4th model, got a link?
In a former thread I posted the following list of HD2 I found the last two years:
1. T-Mobile US PB81120 (more memory for T-Mobile requirements and for USA specialized radio chipset)
2. European HD2 PB81100 or T8585 (specialized radio chipset for Europe)
3. Asia/Pacific (Telstra) HD2 PB81110 or T9193 (specialized radio chipset for Asia/Pacific)
4. Chinese HD2 T9188 aka Tianxi (with specialized radio chipset for China and design adjustments)
5. Dopod HD2 T8588 (identical to T8585 apart from dopod logo)
Ah I was ignoring the dopod, it was the line "there's even an at&t model" I was querying.
As for the 9188,, does that even count as a hd2? Different codename, different case, slower processor, doesn't mention hd2 anywhere in its details,,,,
Here for the US AT&T 1900/850 MHz HD2 (don't know the series number) :
http://pdadb.net/index.php?m=specs&id=2062&c=htc_hd2_us_htc_leo
Here for the DoPod T8588 2100/900 MHz HD2 (actually identical to the European model) :

You have a cooked rom installed so you will be presented with the bands from the stock rom that the rom was based on, not what the hardware is set to.

That had crossed my mind but thought it would pull band data direct from hardware.
Bit of glitch, can this band data be corrected ! is it registry based by any hopeful chance ?
could be, and im no longer on winmo and cant remember anything specific.
Id maybe fire up 'cereg editor', load up my registry and do some searches, see if anything turns up.
It doesnt really matter, the correct settings will be used, it wont affect the function of the radio.

Would like it to show correct bands just to refresh my memory of actual hardware bands when choosing options as travel a lot, although never had a connection issue abroad yet !
Will do a search on XDA & my registry & see what comes up.
---------- Post added at 04:48 PM ---------- Previous post was at 04:31 PM ----------
Found them in Registry:
HKEY_LOCAL_MACHINE\Software\OEM\PhoneSetting\BandType
Any one got the default TMOUS key value data from this path for reference ... ??
The choice between the bands may be set in the registry (band 1 / band 2 / auto), but not the frequencies, of course.
They are hardware only. Hence the different models.
So anyone got the standard TMOUS ROM & show me what options are for Bands.
I want my menu to show correct data for each option related to my TMOUS hardware not the data for the 6.5.x custom ROM donor devices hardware.
I more than realize band frequencies are not adjustable via reg keys.
Simple enough for anyone on standard TMOUS rom to look .
Thanks,
hi every one im thinking about buying a tmous htc hd 2 cause of the 1gb rom 576 mb ram , im just wandering if the phone will work in australia 3g , vodafone , i found out download band for voda is 2100 and upload 900
can some one shed any light on this should i buy the tmous htc hd 2 or t8585
thanks in advance
No, The T-Mo US HD2 won't work on those 3g bands. You want the t8585.
Or the 9193. which is the AU model that will work with ATT USA 850 band 3g
thanks for the reply whats the differnece in having 1gb rom

I'm very surprised to hear that your 9193 locks onto an H or 3G icon with Vodafone. EDGE, sure, but that's 2.5G data, not 3G.
The 9193 supports 3G/HSDPA on 850 and 1900MHz
The 8585 supports 3G/HSDPA on 900 and 2100MHz
Everything I've read about Vodafone points to them using 900 & 2100MHz bands for 3G/HSDPA.
band
i am using 900 2100
i used a cab to add more bands
BAAAAHAHAHAHAHAHAHA!! ROFLMAO
You're an idiot, stop posting misinformation.
If you use Telstra then you need the t9193 model but if you use any other provider you will need the t8585 model to be able to access the full 3G service, I could be wrong but that's what caught me out.
I am on Vodafone and I have the T8585 with H E 3G & G bands via 900/2100.
gamecore is correct T9193 for Telstra, and T8585 for others eg Vodafone etc...
ok i am new to this but can someone tell me what's the different between
the
T8585 and the T9193 (i know that the T8585 is the one with the 512 rom) so is the T9193 the telstra verson of the HD2?
i am going to america next month and just to make things clear
(i am on optus)
if i want to buy a HD2 with the 1GB ROM it won't work in Aus ?
so should i buy the normal verson of the phone (T8585)?
if i just want to use the phone for call,text,mms (no internet browsing) can i get the 1GB one ? or would i still get the T8585?
so if i want the phone to be able to use the internet(not wifi) "on the go" and check e-mail i will need to get the T8585 right ? ( the one with less rom?)

STHD,
A brief lesson in mobile phone protocols, and which model supports what:
T8585 & T9193
Worldwide
GSM, 850/900/1800/2100MHz
GPRS, 850/900/1800/2100MHz
EDGE, 850/900/1800/2100MHz
T8585
Australia (Voda, Optus), Europe, Asia
3G/UMTS, 900/2100MHz
HSDPA, 900/2100MHz
T9193
Telstra AU, USA (most), Japan (I think)
3G/UMTS, 850/1900MHz
HSDPA, 850/1900MHz
So,
Both the T8585 & T9193 can use the following services worldwide, on any carrier that uses the GSM (NOT CDMA!) mobile network:
* Calls
* SMS
* MMS, assuming you have some sort of data plan supporting GPRS or better.
* Mobile web & email, but only at GPRS (data rates of 56-114 kbit/s) or EDGE speeds (up to 236.8 kbit/s).
The T9193 supports 3G/HSDPA on 850 and 1900MHz - Telstra & most US carriers use these frequencies for 3G data.
The 8585 supports 3G/HSDPA on 900 and 2100MHz - Most European, Asian and all other Australian providers use these frequencies for 3G data.
See http://en.wikipedia.org/wiki/Template:Mobile_telecommunications_standards for a heirachical view of the technologies.
Three key points here:
1) You can't (AFAIK) buy the T8585 model from a network provider in the USA. They will all be T9193 models.
2) If you're *visiting* the USA, and indend to to use the phone on Optus when you return, buy the T8585 model from somewhere in Asia or Europe (http://Handtec.co.uk is my personal recommendation). You can still use the phone when you go to the USA for calls, sms, and gprs & edge data, and get full 3G/HSDPA speeds when you come home to Optus.
3) Ignore the 1GB Flash ROM on T9193 model. The T8585 comes with an 8GB SD card - just install all your apps on the card. This has the additional benefit that you don't need to re-install every time you flash another ROM.
Make sense?
Phrak
So basically you need the T8585 for Optus.
If you get the T9193 for optus network you can do everything that the T8585 does but you wont be able to use 3G it will only be 2G or slower for web and emails on your phone.
ok thanks Phark that really help me out working out the issues
just to point something out from Phark post
T8585 Should be T9193/T-mobile verson
Telstra AU, USA (most), Japan (I think)
3G/UMTS, 850/1900MHz
HSDPA, 850/1900MHz
not picking on you (Phark) but just want to make sure everyone gets it or else it will be confusing (am i right?lol)
but another thing is that on the htc website it says that the aus verson (T9193) of hd2 uses "Australia: 850/2100 MHz" i donno if the info is wrong or what...
Also T-mobile and [HD2 US(from PDAdb)comming soon] have 576Mib of Ram which is 100 something more then T8585
So i guess i will get the T8585(Will get that in HK)
Haha and i really like how Phark quote *visiting* USA...but i am really going there Haha
Thanks again Phark and also thanks gamecore

The T8585 *does* have 576MB of RAM, enabled via most ROM Chefs. I'm unsure of the technical changes to enable this, but I've just (double) checked my T8585 HD2 from HK, and it says: "RAM: 576MB; Flash Size: 512MB"

hd2 telstra t9193 - Vodafone Australia
Hey Phrak,
This is the cab i used for geting the extra bands
http://htcpedia.com/forum/showpost.php?p=57342&postcount=6
is this the correct band for Vodafone Australia?
UMTS(900+2100)+GSM(900+1800)
If not what should it say???
Is there a hardware difference that the t9193 will not have the correct data connection? Or is it just software?
Interesting CAB - I've just found the same software built into the latest ENERGY ROM I've flashed to my Leo.
More research is needed methinks. I'm more than prepared to be proven wrong on the T9193 supported bands.
Good day guys. I need your help. I want to replace my motherboard because processor wont work properly(freezes, green screens etc.). So i want to know, is there any difference between international ver. of hd2 motherboard and T-mobile version, and could I buy T-mobile motherboard and replace it in my international hd2. If it is possible, so i want to buy this motherboard
cgi.ebay.com/HTC-HD2-Unlocked-100-Working-motherboard-only-/230603065490?pt=Cell_Phones&hash=item35b1038892
(and if you will find some analog, please let me know)
Thank you for helping.
I believe the T-Mobile motherboard/main board is slightly larger in size to the international HD2 do to the more rom space and things on the T-Mobile version. So you can probably interchange a international main board with a T-Mobile HD2n but I don't know about a T-Mobile main board in a international HD2 as the actual outer casing is smaller than the T-Mobile.
Thank you for fast answer T-Macgnolia. I was thinking about it(i mean different sizes etc) but may be it's still possible, i mean ... its probably my last chance, so if you are don't know, for sure there is someone else, who tried this and know that it works, or know for certain that it's impossible. But anyway i need to replace it, doesn't matter t-mobile or international ver. of mainboard. I just couldn't find international ver. yet. So guys if you have any links of selling this motherboard, please let me know(doesnt matter where, may be in europe too).
I've got the same problem and I've done some research on it, but I'm still not really sure whether or not the international motherboard can be replaced by the T-Mobile one.
Here's what I found out:
(quotes from another web-site)
"Memory:
T-Mobile HD2: 576MB RAM, 1GB ROM
HTC HD2: 448MB RAM, 512MB ROM
The T-Mobile HD2 has a 128MB RAM advantage over the HTC HD2 if we are talking about the stock specs. Latest developments demonstrated that the International HD2 has the same amount of physical RAM, but the additional 128MB has been hidden and thus unavailable, but unlocked via applying custom ROMs.
As far as ROM is concerned, the T-Mobile HD2 has twice as much storage memory than the international HD2, mainly because of the customizations the operator version has (not to mention the Entertainment package including Barnes & Noble eReader, Blockbuster on Demand - Blockbuster’s first-ever video download application on a smartphone, MobiTV, Gogo Inflight Internet Services - six month trial for inflight wifi services on over 2,500 daily U.S. flights and Slacker Radio)."
"Bands:
T-Mobile HD2: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz, GSM: 850/900/1800/1900 MHz.
HTC HD2: Europe: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz. Asia Pacific: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz.
Main difference here is the one and only vital one: the T-Mobile HD2 supports the 1700 MHz band not supported by the International HD2. Additionally, we've posted about how to get AT&T 3G speeds with imported Telstra HD2 from Australia, which supports UMTS 850Mhz."
But still there's one thing that makes me still hope the international version can run with the T-Mobile MB: regardless the fact that the T-Mobile version is 1.5mm taller they both weight 157 grams and plus to that, I think it would be smart move to manufacture the other phone parts in such a way that they would fit both versions.
I hope I'm gonna get some answers from a couple of GSM services I've contacted lately and get back to you with the answers. Brace yourself! =]

T-Mobile is strange about sizes and custom phone cases. My previous phone was a TP2, and the T-Mobile version had a completely different case and front, for no reason that I could see except looks.
So, I got some answers. All of them conclude the fact that it's impossible to use a T-Mobile MB on an international version!
Reasons why:
- the T-Mobile motherboard is longer, so you'll have to rethink how to attach the motherboard to the housing;
- on the international version the flex cables and all the other cables are soldered to the motherboard, while on the T-Mobile version they're connected through various connectors.
Bad news, bad news...well all you can do now is hope to find a used and working motherboard, buy a phone with a broken screen or something else (those cost as much as a used MB) or sell the phone for parts...
Good luck! I'm gonna need it too ;]
Hey spnk! Thank you so much for help and your great research!
I had a thoughts like that, but still got a hope ^_^. However now the story has ended.
I've bought a new one from taobao, costs much cheaper than on ebay(ofcourse it's chinese assembled, but it says "made in taiwan" , so i dont know anything about "makers", but it's well built).
I left old, "broken" one for parts. Who knows, may be it will be usefull.
I hope that you've solved problem with your's.
Best wishes.
