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

HD2 3G Compatibility

Can anyone tell me if the HD2 is compatible with 3G in Costa Rica? The USB stick that is used by the telephone company has the following specs:
HSDPA/UMTS 850/1900/2100MHz
EDGE/GPRS/GSM 850/900/1800/1900MHz
Thanks in advance.

In a word?
Yes.

Can you explain what data tells you this? I'd like to understand 3G a little better.
-Bob-

Since this thread is somewhat-related to a question I've been having, I'll ask it here:
For UMTS compatibility, do the phone and network only have to share one band?
I ask because the Telstra HD2 (UMTS 850/2100) is coming out here in Australia -- where I'm holidaying -- on Tuesday. Back home -- in Canada -- my provider (Telus) uses UMTS 850/1900.
It's been suggested to me on these forums and told to me by a tech support representative for Telus (I have a hard time trusting them, however, because they're kind of dumb) that the phone'll work on 3G with just the 850 band in common with the network, but I want to be sure.
I've done some reading on Wikipedia [also], and that seems to encourage the idea that my phone'll work back in Canada...but again...I want to be sure...

I tried doing research for you and I found out Costa Rican Electricity Institute (ICE) has contracted Huawei to build the network but unfortunatly you will need to find out that 3G frequency, could be 1900 or 2100.
The HD2 uses 2100. The USB Modem works in all frequencies so it would work everywhere.
All you need to do is find out the 3G frequency, perhaps give them a call.
From My experience travelling to Mexico, Guatemala, USA and Canada. All use 1900 3G (Except T-mobile USA uses 2100).
I haven't tried the T-mobile 2100 though so I cannot assure you if it in fact does work. I've only tried AT&T(USA), Telcel(MEX), Tigo(Guatemala) and Claro (Guatemala)
Chances are Costa Rica would fall in line with the rest of North America.
So only Edge works.
Wish you Luck!

OK, now I'm confused! It is my understanding that 3G is NOT available from T-Mobile USA using the current version of the HD2. If the HD2 uses 2100 AND T-Mobile uses the same, why is 3G not available on the HD2 in the US?
If 3G isn't available in Costa Rica because of the 1900/2100 issue, is Edge automatically available? Or could ICE simply ONLY offer 3G, with no Edge alternative?

en costa rica no te va a funcionar, salvo que tu compañia utilice 3g umts2100, y por lo que vengo leyendo utiliza umts 850, o sea que no te va a funcionar...
algo similar me pasa a mi, yo estoy en uruguay con movistar y aqui el 3g es 850/1900, asi que mi querida hd2 no funciona en 3g, igualmente corre en EDGE sin ningun problema...

Telus, like AT&T in the States, puts 3G service on 850 MHz in some towns and on 1900 MHz in other places. Since the Testra version of the HD2 does support 850, you'll get 3G in Canada in markets where Telstra uses 850. If you travel to a Canadian city where they use 1900, your HD2 will fall back to EDGE.
So, you need to find out if Telus uses 850 in your home market before buying that Telstra phone. (By the way, JB HiFi has it for $829A now and Telstra will have it at that price on 1/19.) I can't help with where you can quickly find which frequencies are active in your area, but a friend back home may be a better source than a Telus rep. Good luck.

First of all, T-Mobile USA's 3G freq is 1700mhz or AWS, which is why the T-Mobile version of the HD2 is coming out later. Europe's 3G is on the 2100MHZ freq. You can definitely import a Euro HD2 to the U.S and use it on GSM voice but data would only do EDGE either on T-Mobile USA or AT&T.
Concerning Costa Rica, i tried to look up ICE's network information and i found this on their website: http://www.grupoice.com/swf/kolbi/preguntas_frecuente.html#tecnologia_3g
Si tenés actualmente un teléfono móvil 3G, solamente podés acceder al Plan Kölbi Básico y al Plan Ejecutivo 1000. Para comprar del Plan Básico Kölbi, podés llevar cualquier terminal móvil 3G que funcione en la banda 850 Mhz.
Translated by Google it comes out to:
If you have a 3G mobile phone today, only you can access Kolbi Basic Plan and Executive Plan 1000. To purchase the Basic Plan Kolby, can carry any 3G mobile terminal operating in the 850 Mhz band.
So ICE has 3G on the 850mhz band it seems. Now the current HD2 only handles 3G on the 900/2100mhz, so you wouldn't get ICE's 3G on it.
Now, according to Phone Arena http://www.phonearena.com/htmls/HTC-HD2-US-phone-p_4345.html , T-Mobile USA's HD2 will handle 3G on the 2100/1700/900 MHz band and GSM/EDGE on the 850/900/1800/1900 mhz band. If ICE at least offers EDGE on the 850mhz band, then the U.S version would be the one to buy.

The problem here is that Telus and Bell in Canada are CDMA carriers. From what I understand, the EDGE fallback is GSM, so if there's no 850 UMTS service, my phone just doesn't get service.

Would like clarification on this if possible...

What would happen if I buy the Australian unlocked version (Telstra's NextG with 850MHz 3G); will it work in the 3G in Costa Rica. And if I don't like the Telstra's ROM, can I flash it with the original HTC ROM desgned for Australia?

I'm sorry for disappearing for several days...I forgot that I posted here.
Telus also runs an HSPA network. A quick look through their phones shows several models with HSPA, including the HTC Hero with HSPA on 850 and 1900 along with quad-band GSM. The Telstra HD2 (HTC T9193) has HSPA on 850 and 2100 along with quad-band GSM.
Call Telus and find out how wide-spread the HSPA network is. If it covers the areas where you go and if you live in a place that uses 850 for HSPA service, then the Telstra version of the HD2 will work for you. If you live in a 1900 area, you'll fall back to EDGE. If you live in a CMDA-only area, you'll have spent a lot money on a phone that can't make phone calls.

Okay, excellent.
This is what I was concerned about -- I wasn't sure about EDGE fallback because of the CDMA/UMTS issue.
Telus' UMTS coverage is actually larger than their CDMA coverage, so that aspect isn't a problem.
I'd already gone ahead and bought the phone...JB HiFi was having a hard time keeping them in stock.
Looking forward to getting this up-and-running in Canada (running on a Vodafone pre-paid SIM at the moment) on Saturday.

Remember, if Telus is using only 1900 MHz for UMTS where you live, the HD2 will only pick up EDGE since it has no UMTS radio at 1900. If Telus runs both 850 and 1900 or just 850, you'll be very happy.

Only Edge.. hd2 has all bands option, i selected all but still no 3g or hsdpa
Hi, i'm from Venezuela,
I've just bought HD2 in Hong Kong. It is an unbranded unlocked phone. On Phone Settings i see the Band menu where i can select Network Type and Band Frecuency. i've selected GSM and GSM (1900 + 850), but hd2 only navigates on EDGE. i've also have tried selecting Auto on both Network and Band Selection, but still navigating on EDGE.
besides of HD2 i also have an Samsung Omnia bought from my cell operator (Movilnet), it is set to operate on 850 1900 mhz and it works fine on 3g and hsdpa.
my question is, if the hd2 has all bands that i could select, why it dosen't work on 3G or HSDPA.
could i flash my hd2 with other Firmware or ROM, to get 3G working? i've been reading about TELSTRA in Australia, and i think the hd2 they sell has 3G over 850 and/or 1900 mhz.
or, it wouldn't be possible to change Frequencies or 3G on hd2 bought from Hong Kong?
thanks.... i'll appreciate your....

The device does not come with all 3G bands and that is why devices that are sold in specific regions only work where bands are the same. Where the bands are different, they will not work.
Thus, if your device is not 3G compatible in your area, there is no firmware drivers that can help as this is to do with hardware components in the device. Getting the right device for your region is paramount.

3G Networks hardware LOCKING to each carrier by HTC

Among those of you with a deap knowledge of the inner working of HTC phone for 3G networks.
Is HTC doing something to phones for each carrier to lock the phone to a specific carriers 3G network and no other.
I'm asking because I was talking with a freind of mine who was given a HD2 as a part of a promotion for use on AT&T 3G network (850/2100). He uses T-Mobile and tried to get it to work with his T-Mobile SIM with no success. He also told me he had a conversation with someone from HTC that told him that he would no beable to get his HD2 to work on T-Mobile because the hardware will not work with T-Mobiles 3G network (1700/2100).
If this is the case does anyone know if it changable, is it a Firmware issue that can be changed or is it like hard wired physically?
Then the question is if we are buying these phone, some through contracts others outright, do we want to told whos service we have to use!!
Lets have some good discussion...

there are billions of threads on this.
3g is radio/hardware dependent. he'll unfortunately be stuck on EDGE.

He will have no issues using the phone with T-mobile usa. He will not get 3G because of the bands. He will just have edge. But calls, mms, text, email, and internet will all function properly.

Clarify this please
I bought my HTC HD2 in USA (unlocked) and here in Peru, where I live, I cannot get it to work with 3G. If I lived in USA, is there a way to know with what carrier I would get 3G ?

So you are on Claro in Peru?
For 3G you need a phone with 3G 1900 support. If it is the T-Mobile version, that would have 3G on 1700/2100 bands which would be no good. If you got an AT&T handset (850/1900) it would work for 3G for you.
You need to understand what 3G support your version of the phone has. For example mine (Telstra Australia) is 850/2100 - which would not be able to pick up 3G in your network - however it works excellent with Telstra (850) in Australia and currently working well with StarHub (2100) in Singapore.
Your phone is quad band - but that is GSM quadband not 3G - it is 3G dual band and that is what is important for your connection.

Thanks for your response. Yeah, today I did my homework and found that my HD2 has UMTS (HSDPA) 900 - 2100 bands, a fact that is not good because Claro and Movistar in Peru operated the 850 - 1900 bands for 3G.

Up to 2 Mbps upload and 7.2 Mbps download speeds
Quad-band GSM/GPRS/EDGE:
850/900/1800/1900 MHz

Will TMobile US HD2 get 3G in Asia?

Simple question, but hard to answer: will this US phone work in Asia with UTMS 2100, at 3G (HSPDA) speed?
I know an International HD2 going over on TMobile or AT&T roaming will only get EDGE.

I want to know a similar thing: Will the T-Mobile US HD2 work on Western European 2100MHz 3G band?
(I won't be using it in the US, so the fact that the international version doesn't work on US 3G is of no interest to me.)

A simple answer: it will because it supports band 1 and 4 3G.

Simple Answer: Yes

Thanks everyone who replied. I'm making a trip to LA in about 3 weeks time to grab one at a T-Mob shop. Hopefully the stocks will not be an issue by then...

Bringing my hd2 to Europe...

Hi all,
I'm planning on going to Europe, specifically Amsterdam and Sweden, next year. Will my HD2 work in Europe? With data? (I realize I will have to buy a plan with an operator over there)
Sent from my HTC HD2 using XDA App

Yes it will work with any GSM provider worldwide, so long as you SIM unlock it. Todo so, either call T-Mobile if you are a customer, or go online and find a site that SIM does SIM unlocks, such as http://www.htcunlock.com and pay them to do it(around 15USD). And as far as data is concerned, you will get EDGE and GPRS only in Europe with the TMO US HD2 as the 3G bands are different.

Ah good My phone is already unlocked so I'm straight on that front. Going without 3G is no problem, I'm glad it'll work with EDGE.
thanks for the reply!

Correction: the TMOUS HD2 will work on 3G in Europe.
HTC clearly says 1700/2100. 2100 is Band I for Europe. 1700 is Band IV for T-Mobile.
