HTC US version in Europe ?

Hi,
I plan a business trip at the end of this month in the US. Ive currently an HTC P3600 but i would like to buy an HTC Touch. (I prefer the iphone but it lacks business application like Exchange synchronisation).
As i'm in the US, i would like to take advantages of the $/Euro convertion and get direct 40% off my phone.
Question: US Mobile Network and European Mobile Network are not compatible. The US version of the HTC touch is capable of both mode ?
Do you recommend the HTC TOuch or any other ?
Thanks
Ced

What he said, get a GSM phone. Even if it is locked to a carrier you can get it unlocked.

[Q] HTC HD2 T9193 TELSTRA to ANDROID, Question about 850 BAND

Hi... Im from Costa Rica, our unique phone provider here (ICE) works with 850 band for 3G, which is the same as the Australian and AT&T as you know, so I had to buy my HD2 in the T9193 version. I found that windows really sucks, so I decided to change it to Android, I watched videos and read a lot, finally I succesfully did it and it's working just fine. But now, when I try to change it to 3G it doesn't work, I just realized that when I get into the phone Identity on Windows it says:
Model No
HTC HD2 T8585
Then on software information:
OS:
5.2.23152 (23152.5.3.12)
Manilla version
2.5.20191914.0
Rom Version
Dutty´s HD2 FAM ROM (V13a) WWE
ROM Date
25/12/2010
Radio Version
2.14.50.04
Protocol Version
15.42.50.09U
and when I try to change to 3G it says
Band Frequency
Auto
GSM (900+1800)+UMTS(2100+900)
GSM(1900+850)
UMTS(2100+900)
Looks like the Rom that I downloaded and installed in order to be able to change it to android changed the T9193 settings and the 850 Frequency is no longer supported. Here are my questions:
#1- Do I have a T8585 now?
#2- Do I have to change the rom back to Telstra to make it work on 3G?
And then when Im on Android Im totally lost. I tryed to find where to change the settings to get 3G but it only says:
Network Mode
WCDMA only
GSM Only
GSM/WCDMA auto
This is the Android version I installed:
Model Number
HTC Desire HD A9191
Android Version
2.2
#3- How or where can I change or find 3G on Android?
#4- Please tell me what to do so I can run android, and use 3G on a 850 frequency since I bought the Telstra T9193 version please.
Last question is:
#5- Is the band Frequency a software issue or a hardware issue?
First 2 questions are for Windows, the #3 and #4 are for Android. Last one is a general question.
I will really appreciate your help.
Thanks in advance...

[Q] Difference Between HTC (Z710e) Sensation V.S. HTC Sensation (WW Version)

Can somebody tell me what is the difference between HTC (Z710e) Sensation versus HTC Sensation (International Version) in terms of specs? I can't seem to justify why there is a very big difference in price. The Z710e being much cheaper.
Thanks in Advance.

I have the Z710e model and it's the generic European unbranded handset (running 1.35.401.1)

No Carrier Logos out of the box? Factory unlocked? No custom firmware?

100% stock - so long as you get x.xx.401.x (European) FW on it

i have Taiwanese Z710e (running 1.35.709.1)
it's stock ....

Z710e here... No problems, unbranded, S-ON.

Okay..that settles it then. I think I'm going for this Z710e.

Yes but it's from a different region. Depends where the OP is from really

If you are talking about the price difference you see in the US, that's because
- for the US version, most people selling it bought it from tmobile at a discount price with contract. In order to sell it, they have to lower the price to slightly cheaper than the full price, which is 550
- for the international version, it is not available in the US officially. People imported it from Europe or Asia, at full price. To cover cost, they sell it at above the full price of the device.
Hence the price difference. There isn't any difference between the specs of the two. The Us version has tmobile logo on it and tmobile branded software. But once people can get s-off, that would eliminate any software difference between the two. The US one is branded as a 4G device, and the international one isn't. But that's only because only carriers in the US brand HSPA+ as 4G....

just a quick question also only this time regarding the australian z710a telstra model. are they still 4g etc or are they of lesser spec.

According to HTC Aus website, its 3G speed is capable of 14.4 Mbps so it is a "4G" device by AT&T/T-Mobile standard...
Looking at the bands that this phone supports, it seems to have the same hardware as the Canadian Bell model. Bell also brands its as a 4G device, btw.

So, did I understand correctly that ALL Sensation versions are absolutely identical from the point of view of hardware and they all support HSDPA+, just some operators call it 4G and brand the device correspondingly while others do not?

The 4G supports different frequency bands to the normal GSM model
Network*
HSPA/WCDMA:
Europe/Asia/T-Mobile US: 900/AWS/2100 MHz
Quad-band GSM/GPRS/EDGE:
850/900/1800/1900 MHz
*Network bands in regions other than Europe and Asia Pacific may be different, depending on the mobile operator and your location. Please check with your mobile operator.

EddyOS, thanks for your reply but now I'm even more confused
You say that:
HTC Sensation 4G is for 900/AWS/2100;
HTC Sensation Z710e is for 850/900/1800/1900, right?
Does this mean that HTC Sensation Z710e doesn't support UMTS (and, hence, HSDPA/HSDPA+) at all???
My operator works in 900/1800/2100(UMTS with HSDPA) bands. Does this mean I should choose Sensation 4G to be able to use high-speed Internet?

I have a Z710e and can connect at HSDPA

Then, the difference is that 4G just doesn't support 850/1900?

mine Z710e works on Tmobile US HSDPA. Full bar usually get 6M down 2 M up.
people say Tmobile Sensation 4G has faster data speed than Europe/Asia in US. like how much faster?

Sensation z710a and z710e
Hi Friend this is my first answer, the difference is simple but at the same time complex.
HTC Sensation like other phones has variants like this.
z710a:
GSM Quadband 850/900/1800/1900 MHz so you can use 2G networks with all carries but...
UMTS 850/1900/2100MHz only and if your carrier doesn't support this bands you can't use 3G or 3.5G with them.
z710e:
UMTS 900/1700/2100MHz here the same if your carrier doesn't support this frequencies you can't use 3G or 3.5G with them.
These are the main differences, and it's the same like happend with other brands like Samsung
S5360 work 3G with 900/2100
S5360L works 3G with 850/1900
S5830 work 3G with 900/2100
S5830L works 3G with 850/1900
I don't know why this differences because i thinks that it's cheap and easy to simply make phones that work 3G in pentaband 850/900/1700/1900/2100, but for any reason and i don't know why is like that for now.
I hope helps you and other people too.

change gsm bands

hello there
i`m from IL and i want to know if i can change the GSM bands to my location
as i saw a few post on that but iwm dont understan that
thank all

I think the gsm bands are for the network provider (tmo, att, verizon) you cant change hardware.

I assume you mean the data network bands not voice or 2G.
There are 2 physically different phones z710e (most of the world & TMobile US) & z710a (US AT&T). Look at the following and put in your country to check carrier compatibility.

The second post was for a completely different phone.
The first post (I had a quick scan and will look in more detail if I have time) didn't seem to address the issue you have.
As far as I know (happy for someone to shout me down) the HTC Sensation is NOT capable of universal frequencies, it is EITHER:
Z710a (2G GSM 850/900/1800/1900 ----- 3G HSDPA 850/1900) (US AT&T)
Z710e (2G GSM 850/900/1800/1900 ----- 3G HSDPA 900/1700/2100) (US T-Mobile)
That's fixed in the hardware of the phone and can't be changed. As you can see GSM is the same BUT the data side of things is where it gets different, you will always get EDGE as it's 2G.
The Baseband mentioned is flashed as part of the firmware.
The RIL (Radio Interface Layer) is the bit between the ROM and the radio. That will almost universally come with the ROM and will have a pre-requisite radio version that you have to flash separately.
Now if there is a way to change the 3G frequencies I'm sure there are many folks that would like to know how, it'd make the Sensation more universally available and hopefully cheaper in the 2nd hand market.
You haven't mentioned what your exact issue is, what are you trying to change and why ?

you answer me thank u and have a nice day

I was on the phone with HTC last night and according to the tech there the UMTS bands can be changed on the T-Mobile Sensation 4G, but this would require a custom rom. I am not sure if there are any roms out there that do this already.

[Q] convert HTC Sensation Z710a in to Z710e

I have a HTC Sensation Z710e rooted and S-off with custom "Android Revolution HD" ICS ROM. My wife has a HTC Sensation Z710a with an official ICS ROM. We are both on dinosaur Rogers network that gauges on its clients planning to switch over to WindMobile. The problem we are having is that my wife's Sensation won't work on WindMobile network. It's because WindMobile operates on AWS 1700 band that is supported by Z710e model (HSDPA 900 / 1700 / 2100) but not by Z710a (HSDPA 850 / 1900 / 2100).
Going trough all different threads in Sensation forums I am getting lot of conflicting info so my question is; if I root, S-off and install Android Revolution HD ROM that comes with it's own radio and essentially converts regular Sensation in to Sensation XE; will my wife's Sensation Z710a be able to support AWS 1700 band as well?
Is it only software (firmware, baseband, radio) or actual hardware that differentiates Z710e and Z710a models? Both my wife's and mine phone look exactly the same unbranded HTC Sensations...

Whilst you can run the have the same ROM and Radio versions on both phones you cannot convert Z710a <-> Z710e. They have different hardware for the data frequencies.
So in simple terms if your wife want's full 3G functionality she'll need a new phone. She'll still have Voice and Edge though.

Hello, I'm from Argentina and I have an almost unused Z710e, if you want we can change if your wife is in the same state, greetings.

We were testing the functionality of both phones in WindMobile store and my wife's phone only connected to their roaming partners. I am not sure if above mentioned company even utilizes regular GSM frequencies... Perhaps the reason why they are so affordable is that they run VOIP all the time as long you are connected to theirs network. So although we spend 99% of the time in their coverage area, she would be paying roaming for everything (voice, text, data).
I am getting some info in different thread that I will try to act upon and see how it works. I am really desperate to cut all my ties with Rogers. I used to have cable TV and internet with them as well (now cancelled) but they keep on screwing customers more and more.

That perhaps would be the best thing to do in order to get what I am trying to achieve. My wife's phone is only 2 months old, essentially new...
I've decided to purchase last year's model for her because although being fan of HTC products I would never buy a cellphone without mSD slot (that's what I've hated about my HTC Diamond before). I am just a bit worried about possible issues shipping phones back and forth between Canada and Argentina. Is there someone in Ontario, Canada interested to trade Z710e for Z710a?

GSM (voice) will work fine for both phones on all networks as will EDGE (2G data) on all networks, the issue is the 3G data side of things. So I don't know why GSM doesn't work it certainly should. They both have: Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz. The Z710a/Z710e difference is purely in the 3G side of things.
Re-reading your post, ahhhh VOIP == Data usage. If they purely use VOIP then you're stuffed, I'd be surprised though but I can't comment on that network.
Have a look at: http://www.gsmnation.com/htc-sensation-z710a-3g-850-1900-mhz.html
Then Network Compatibility -- Canada
Unfortunately they seem to have removed the Z710e phone, just invert the 3G ticks/crosses for it.
