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

will my hermes work on Tmobiles 3G in the u.s?

i was reading this article and it said it wouldnt work..

Where are you getting 3G for T-mobile in the US? I only heard it was in NYC at the moment.

Sadly, the answer is most likely not.
T-Mobile is deploying 3G service on the 1700 MHz UMTS band, which the Hermes, and a lot of other phones, can not use.
My confusion is that T-Mobile USA has submitted the Kaiser for approval to the FCC, and the manual that comes with it lists the Kaiser as supporting 1700… in the Japanese version.
So are they using a modified Japanese version, or releasing it as a EDGE-only phone (which would be a mistake IMO), or something else? I sure don’t know, but I’m expecting to have to replace my beloved hermes with something else if I want to make use of the upcoming 3G.

After they fully release 3G, I hope that T-Mobile USA ventures into getting the Raphael since they NEED a good flagship of a phone in their lineup. AT&T already has the Kaiser and iPhone (not a fan, but it's a popular phone though)
But I'll be patient. I have 1 more year before I'm eligible for an upgrade, hopefully they'll have something worth it by then...

Answer
Absolutely not. It wont now and it wont in the future., T-Mo uses 1700 and at&t uses 2100. They will not interchange because neither side wants the others users sucking up they're bandwidth. Do not expect to see 3q dual band handsets that are "intended" for the US anytime soon.

Well, that's subject to a bunch of things, while AT&T may not want "T-Mobile Customers sucking up their bandwidth", EDGE is pretty fast in comparison to some DSL connections and the vast majority of T-Mobile customers get their service through AT&T towers. So, in a way, T-Mobile customers are already sucking up AT&T's bandwidth. Once quadband UMTS chipsets become common, or T-Mobile decides to abandon its 1700mhz plans, I'm sure that AT&T and T-Mobile will reach a roaming agreement just like they did with GSM/EDGE

[Q] Conflicting info RE: SIM lock to T-mobile for off-contract

I imagine several Canadians like myself will be considering the Dell Venue Pro for use on our new AWS 3G networks (Wind, Mobilicity, Public Mobile, etc.) or, in the alternative, for EDGE 850/1900 2G use on Rogers (or Fido, Chatr, etc.).
(This post is NOT a question about the frequency bands that the DVP supports - there are plenty of other threads for people who are confused about that.)
For the few who managed to get the DVP from Microsoft Stores off-contract (i.e. for $499) on launch, has anybody tried putting in a non-T-Mobile (i.e. AT&T) SIM? Some posts and sites are reporting that Dell will SIM lock the phones to T-Mobile whether you buy them with a contract or not. Has anybody tried calling Dell and asking for a SIM unlock code?

Someone with a DVP from a MS store has already confirmed they tried an at&t SIM and it worked, in one of the threads here.

Okay cool.
Obviously I realize that it will be difficult to confirm until mid-December, but hopefully the same thing will be true of off-contract Venue Pro phones ordered from Dell.com
A sidenote to those who are confused about the Venue Pro 2G and 3G bands (a tragic bit of confusion):
First, pdadb.net lists a SECOND model of the Venue Pro, set to be released in December or January, that does UMTS on the 850/1900/2100 bands. I can't find any independent sources for this.
Second, Rogers users will be pleased to recall that there have been reports, over the past year and a half, of limited 2100 mHz 3G service in parts of downtown Toronto and other Canadian cities.
Third, the FCC documents posted for the current AWS model of the Venue Pro include letters from Dell apparently promissing the FCC that although the phone's radio is capable of 3G on the 850 and 1900 MHz bands, they will prevent it from doing so in firmware. This has led me to speculate that the phone's hardware is indeed capable of 850/900/1700/1900/2100, like the iPhone 4G - but with certain bands shut off in firmware depending on the SKU. Very cool, and some hope if future radio firmwares are interchangeable.

I was going to test this for you using one of our DVPs here in the office, but apparently ATT will automatically charge the loan ATT user in the office for data once the smartphone authenticates with the network. He's already been burned once by this and wants to hold off testing again until he actually has a smartphone plan on his line.

It works with ATT
My VP does work with ATT only when 3G is turned off but that's to be expected.

I have been using my Microsoft store Tmobile Dell Venue Pro on ATT since day 3 or so. Been over a week.

You will be able to use the phone fine on AT&T. But you will be limited to Edge only.
The Dell Venue Pro uses 900 / 1700 / 2100
AT&T's 3g network is: 850 / 1900

Well, thank you everyone for the info. That's quite a relief and I appreciate you testing your Venue Pros.
Sounds like the buyers of the off-contract Dell Streak aren't as lucky:
http://liliputing.com/2010/08/dell-...m-locked-to-att-with-or-without-contract.html
Again, I have no illusions about the 3G/2G thing. Though I live in Toronto, and odds are that I will get 3G on the 2100 MHz in some parts of the downtown. But 2G is fine until my Rogers contract runs out and I can switch to Wind or something.

There are 3 ways to unlock a phone:
1. Contact the carrier (in this case T-Mobile), and complain that you need to travel and switch to a local sim...you'll get your code.
2. Use one of the cell phone unlocking sites.
3. Wait for XDA to release an unlocking tool.

I'm going to California to visit some people in December. I'll probably order from Dell.com and have it shipped to them. In the alternative I could go to the Microsoft store in L.A. (assuming demand dies down a bit and they have stock by then).

LOL

I hate to sway off topic, but which other WP7 devices are sim free? I swap sims a lot. Its my main deciding factor. Thanks.

Will this work overseas?

I am thinking of purchasing this phone as a wedding gift. He lives in pakistan. Will unlocking this phone and popping in a local sim be enough, or are different bands used in the US that would make this phone incompatible?

The phone should work fine, but the big question is will 3G work

en.wikipedia.org/wiki/List_of_UMTS_networks#Asia
So it should work as far as i can tell.
But i am also wondering, if it'll work just fine in Germany, because e.g. Vodafone uses 1900 as UMTS-Uplink 2100 as UMTS-Downlink - according to Google's specs, NS supports UMTS 900, 2100, 1700 and GSM 850, 900, 1800, 1900.
So what's with the UMTS-Uplink

Thanks for the responses guys. I think pakistan still has some time before introducing 3g fully, so no worries.

Well, i did some research and seems like UK also uses 2100 down and 1900 up, which would mean, if it works there it should work here in Germany too.
But i really cant tell, because i just don't know really much about these frequency-stuff.
Would be glad, if someone could help us out on this one

It works with every carrier in the Netherlands and Germany as well.
I'm gonna order one tomorrow to replace my N1

It is SIM unlocked whether you buy it contract or with out contract (full price). it should pretty much work anywhere in the world who uses GSM technology, pop in your sim card and use the phone. The only concern is the data, you have to check the network frequencies, worst case scenario is you get the 2G, Edge speed, if the country the you are going is not the same as T-mobile USA network data frequencies. This is my understanding, if somebody out there who knows if I this information is wrong, you are more than welcome to correct me

I'm getting the Nexus S buy the end of december. The thing is that I'm in India and we use the 1900Mhz uplink and 2100Mhz downlink.. Since the Nexus S uses only the downlink frequency does that mean that the phone will not work on the Indian 3G networks.?

ordered mine from USA, will be getting today by DHL, will update.

DVP 3G Europe/US Roaming

If I understood right at least some DVPs have radios capable of using both T-Mobile US's 3G network and European 3G networks. Has anyone tried this? Are we sure that all DVPs have the same radios? Or do the European ones have the US frequencies disabled or something?
Thanks in advance for any info,
Tom

The US ones have AWS for TMOUS, and European 900/2100.
Whether they will actually provision correctly and be usable w/ 3G services in non-US locales is anyone's guess. The US DVP has only just recently been unlockable and I don't think we have had any reports of actual int'l roaming success yet.

I think its been mentioned in the unlocking thread that people have used it in Europe and from the listing of the DVP I've seen the specs indicate its has the exact frequencies as the US one. I would expect it to work, unless Dell has done something really screwy (but thats not impossible) but hopefully someone can confirm for sure.

People are claiming that European DVPs have AWS 3G support? I don't think so.
Although it is conceivable that it's there and simply unadvertised, I believe non-US DVPs have 900/2100 *only*.
US DVPs have 900/2100 *and* AWS.

Actually I was referring to people with US handsets being used in Europe, not the other way round. And its possible the Euro version is hte same as the US one, looking at a video of a DVP released in India it shows the same frequencies as the US one, and Clove also lists the same 3G frequencies so I would lean towards all DVP's bring usable in Europe and the US.

With today's big news, what's the point?
Once AT&T shuts off AWS UMTS in a year or so we are all gonna be left with paperweights anyway.

NAY, I SAY THEE NAY!!!!!!!! Could be right though, but I was planning on ditching the DVP for a penta band Nokia so I guess I'll be ok - save for being on at&t!

3G works here

They are saying it will take "several years" to transition T-Mobile users. Lets hope the regulators see sense and block it in any case...

So I have a European DVP now. Anyone know of an app that will tell me the radio frequencies it supports? The System Info one doesn't seem to.

It supports 900 and 2100.

How did you find that out? The box says UMTS 2100/1700/900.

The European box says the phone inside supports 1700?

my US T-mobile DVP (unlocked) works fine on tmobile Germany and I get about 3000k download 2500k upload. I am in a fairly bad region for network speeds. But I have hit upwards of 7000k download in some bigger cities.
