I Got last month one SX56 from Siemens, stated by the store to be use it worldwide.
However, it never connected with cell company in Los Angeles, which I
didn't bother with it since I was planning to use with TIM in Brazil, and the chip that I was using is from over there. I have arrived in Brazil two days ago and still no connection.
My question to you is that the band switch program(from XDA, installed by the store) shows that 900/1800Mghz band is possible, however the reference guide booklet only mentions dual band 900/1900;Is the intermediate band 900/1800 a software function commanded by the band switch program or the actual hardware must be triband in order to work the 900/1800?
Please note that under automatic configuration, it gives a choice of choosing TIM Italy telecom, which operates 900/1800.
Any suggestions or advices on your part are welcome.
Thanks,
Alex
Your device is NOT capable of working on the 1800 band, when they stated the sx56 as worldwide use they must be referring to the 900 band which is used here in the UK and other countries by some service providers.

Hi there!
I live in France and I go often to California. I always had a spare GSM phone tri-band for the US and Canada.
Last March, I bought an O2 xda in Australia, in a Telstra shop, thinking it was a bi-band phone. Back in Paris, I found this site and learned how to access tho the GSM menu (I had found myself how to access to the Wallaby bootloader 5.17, but I didn't press any other key after the message "GSM OK").
I've just come back from San Diego and while I was there I changed the band to "1900"... and the xda worked perfect!!! Back in Paris, I've switched back to 900/1800 and I'm using again the European networks
Thank you!
What?
We've always believed the phone had physically different hardware for 900/1800 and 900/1900 operation, and I seem to remember seeing negative test results.
The O2 XDA you bought for sure is 900/1800 and not 900/1900 ? (remember: it would work in Paris if your provider is on 900).
Let's all follow up on this one carefully. For now, let us not imediately assume the units are tri-band.
I have heard that O2 are likely to release a tri-band version with 64Mb internal RAM.
This will be called the XDA 64i and is likely to sport Bluetooth also.
Any further news on this appreciated.
Hey ArtZ
Let us know if your carrier is a 1800 Mhz Carrier.
If the XDA is triband that would be absolutly awesome.
:lol:
Hey guys
Now this is VERY IMPORTANT NEWS
Can we have more info and more confirmation (more experience in this ?)
My carrier, SFR is a 900Mhz carrier. In fact SFR (Vodafone) and Orange (France Telecom) use the 900 Mhz but in some places to avoid network congestion they use also 1800 Mhz band. BOUYGTEL (Bouygues Telecom) uses only the 1800 Mhz band.
I've just made a test. I have configured the phone as 1800 Mhz only. I couldn't find my carrier SFR. Then I tried to select manually the network and I only could see BOUYGTEL (1800 Mhz). I have tried in the past my XDA with a BOUYGTEL car also and it works fine. So my phone is configured for 900/1800 carriers.
After this, I changed network again (1900 Mhz) in Wallaby bootloader. Then I cannot see any carrier. In California I was connected to Pacific Bell using the 1900 setting.
As I told you before, I bought my xda in Australia last March with the latest firmware. It's a 64 Mb internal RAM
I'll be back in California (on vacation) on June 30th for 10 days. If you wanna make tests...
Hi ArtZ
This sounds great.
Sorry to bother you, but can you tell us please which firmware U are using for the PDA and for the phone?
Thanx! :idea:
PS: for me it will be end of the year, so this is a long time...
I forgot to tell you the versions installed (I haven't updated them yet) are:
RUU 3.14.17
RSU 4.17
I don't think my xda is the XDA 64i. It has no Bluetooth. I think the 64Mb version just came out in Australia when I was there in March. There're are maybe harware changes with the 32Mb version and the 64Mb is a tri-band.
Hope that helps.
It's me again, sorry to bother you.
I run all the tests from the Wallaby bootloader. The version I have is GPRS 4
It will be interesting to check if you have new versions over there.
I found out that the xda has just arrived in France by Bouygues. I will try to get more information about it but I think it's the same model I have. Bouygues doesn't say if the HTC iPDA is a bi-band or a tri-band telephone

Hi,
My version is GPRS 4.1332s54 What ever this means? :shock:
how to change the frequency?
HI Artz,
Great news you have given. Can you please clarify step by step how you changed the network frequency of the phone?
Thanks
Blurr
DANGER
Look on the back of the device, the part number will tell you if it is a 1900 unit or not.
PW10A1 is the 900/1800
PW10B1 is the 900/1900
The Bootloader is identical. CE is different as the option to chose the 1900 band (which you have to do manually) is only in 1900 CE versions.
The hardware is different between the two versions. The radio circuits and filters are different. You "could" switch the radio of a 1800 unit to try and do 1900, but your coverage would be extreemly poor as the 1800 filter is actually filtering out half of the 1900 band.
Your 1900 operator will NOT like you.
superblurr, lazy boy! :roll:
All information is here, in xda-developers.com. Just take a look at this page
http://www.xda-developers.com/bootloader/
It will be nice if someone from the States comes to Europe and try his xda here. And if you go to the States (or Canada) take your xda with you. It's the only way to find out if there're different models
My version is:
GPRS 4.1332s54 (as silversurfer)
RUU: 3.14.17
RSU: 4.17
Model: PW10A1
Anybody got a spare XDA they want to send to the US for testing for a few days? It usually only costs me about $12 to ship something that size to Europe, and takes about 5 days. I would imagine it to be similar the other way.
this sounds great! i own a 900/1900 from t-mobile. is it then possible to change my 1900 into a 1800 mhz? because i get sometimes no network signal. i live in europe, and need the 900/1800...
Can anyone explain please?
I bought a US T-Mobile (PW10B1) and did a SER1.2 flash, it went flawless....Thanks to the xda-developer team and Jef, you guys are the best!! The only bug I notice so far is Phonext which is not working at all. I am using the phone in Singapore using the 900/1800 band and it works perfectly. I've been reading about TMO2003 in this forum, my question is does this upgrade come with bandswitch.exe, this feature is very essential to me as I travel very extensively btw Asia, Europe and the US. By the way does anybody know what is a .rar and .nbf file? :?:
.rar files are compressed files like zip.
download a freeware prog called winrar and you'll be all set.
The UK will see the new XDA from O2 by the end of this year.
It's now known as the XDA II
it will be 64Mb, tri-band and bluetooth plus a built in camera and enhancements to the wi-fi link etc.
Thanks Rustek. How about .nbf flies? Is TMO2003 for PPC2003 only? what's the diff. compared to SER1.2?
I don’t know how to find out what band my smartphone uses. It’s T-Mobile, so it should sell in US, where GSM band’s 1900. But my T-mobile was in box, designed especially for Russia. The letters are in Russian, a GSM band indicated on the box in big black font is 900\1800.
But device information tab in WM 2003 displays "Hardware Version: PW 10B1" (as far as I understand that means 1900 band). In spite of this on the back of my device is a sticker with PW10A2 sign. Where's the truth?
Maybe my device uses 1800 frequency?
But anyway in the band selection tab there's only 2 bands 800 and 1900 (
If my device supports 1800 band, how can I activate it?
The seller’s support tells T-mobile MDA supports 1800… But they can’t explain how to enable it.
I don't know whether connected my second problem with previous. I think it is.
Sometimes my device doesn't find network after it lost it. Example: after leaving an underground subway station. To find a network I have to turn the phone off and then to turn it on.
My radio version is T310. If this problem doesn't connected with the first, maybe I just should change a radio version to a newer one?
The sticker tells the truth normally. Are you going in to bootloader to choose your band?
How can I choose GSM band through boot loader?
Enter bootloader by holding power button while pushing stylus in reset hole, when bootloader appears push the button below antenna, you will then have all gsm options, choose 900/1800.
You may be S O L!!!
You better hope your XDA is not a 900/1800 MHz one otherwise you're going to be SOL unless you plan on living overseas because here in North America, the wireless carriers like AT&T Wireless, Cingular Wireless LLC and T Mobile USA use EDGE/GSM/GPRS on the 850 and/or 1900 MHz GSM aka Next Generation network. 900/1800 MHz GSM is used overseas and is considered the international GSM bandwidths. Cheers!

Your hardware is not capable of working on 1800 band.
I would like to know how many differences there are between this two kind of dual band.
i've bought a T-mobile from USA (i'm still waiting for it so i don't have it now) and i saw that it is a 900/1900. I'm in italy, so i would like to know if i'll use only 900 or 1900 too (i think in italy 1800 is used).
i think i'll have to unlock it, the vendor told me it is a pocket pc 2003, do XDAunlock, work on it?
(i'm sorry for the last off topic question...i post here to not make too many post around the forum)

I'm sorry to tell you since your network works on 1800 Mhz your new T-mobile PW10B1 wont work on this frequency it's made for 900/1900 Mhz if you unlocked it or not it's not gona work, you need the PW10A1 devices they work on 900/1800 Mhz.
but there are cellphone companies in eu who use 900 maybe there are some in your country
if not well thats too bad
oh....no..... :shock:
is there anithing i can do? radio update??? something like this!
Your special edition ROM can help me?
from what i've been able to understand about the 900/1900 then it's a hardware limit the GSM part of the xda1 will have to be physically removed which would most likely be way more expensive then getting a new device
of cause i could be wrong
The XDA1 is available in two flavours (from what I read):
USA: 900/1900 bands
EU: 900/1800 bands
Since both flavours support the 900 band, you should be able to use it in Europ on one of the 'old' networks.
In Holland both KPN and Vodafone have nationwide coverage on 900MHz.
Since TIM is and 'old' company too (Telecom Italia isnt it?) I guess theyre on 900 too. To be sure: check the websites of the Italian mobile operators. Be aware that reception in some areas might be less than if you could use both 900 and 1800 bands as more and more operators are extending their networks on 1800 only (because of lack of free 900 band frequencies). I noticed this a few years back in France where in rural areas there was no coverage with a 900 phone and full reception with a 900/1800 phone (same network).
Reading the forum i've read that is possible to chose band 900/1800 and 900/1900 by bootloader and pressing calendar...can this be true for some model?
p.s. Of course TIM uses 900...i wonder if it will ever use 1900 one day
i think UTMS or some other replacement will take over before us and eu start to use the std's of eachother
just another question, i found information about special edition rom. It says that with bandswitch.exe some devices may work with other "not natural" band. So i'll try when my XDA will be shipped.
TIM wil NEVER use 1900, at least not in Europe. The 1900 band is not available for telecoms in Europe (just like the 1800 band is not available in USA)
I've got T-Mobile from US working in Russia on 800/1800 through ROM upgrade. What it did - it removed SIM Lock and turned the device into 3-band. Works perfect.

i haver never heard about anybody being able to make a dualband into a triband using just software the filters and mixers in the hardware part og the gsm are different
I have never heard about that either. As far as I know frequencies are hardware based. Otherwise we could flash our XDA's to anything we wanted.
I have researched this for weeks and weeks since I need my XDA I to work on the 850Mhz network in the US quite badly.
Please post exactly how you did it
1800/1900
I got the same problem you do but reverse , I'm in the U.S and bought the phone from Europe ( qtek 1010 ) my phone will not work in the U.S because the network here is 1900 and in europe 1800. If you want I can trade with you if you have the same phone. I got all the package in a box.

There are 3 major networks in Italy that have 900 mhz networks.
They are:
Telecom Italia Mobile (TIM)
GSM 900/1800
Vodafone Omnitel N.V.
GSM 900/1800
Wind Telecomunicazioni SpA
GSM 900/1800
If you are within any of their networks you should have service with your
current Wallaby. (XDAI). You should be able to insert your sim card and go.
Some ROMS auto select the available network, others do not. There is also a program that you can cook into a ROM that give you a software selctable band switch.
I hope this helps?
Joe
Just to clarify my last post:
It has been discussed on this forum, for a few years, that you cannot
change a 900/1900 phone to 900/1800 using software.
However since your phone does operate on 900 mhz and there are
900 mhz throughout Italy, including Sardinia, you should have no problem using your current phone. In fact I have used my USA 900/1900) XDAI in Italy.
Let us know how you make out.

900/1900 T-Mobile -- Swap for an 900/1800 XDA ?
Straight swap...I made a mistake and bought a T-Mobile from the US thinking it would work in NZ....it won't and everyone on the forums agrees....so only option is to replace with a European one...
If anyone is interested, post a reply and we can set something up.
Cheers, Hamish
BandSwitching
I live in Jamaica, we have to GSM networks, 850/1900 & 900/1800 my XDA1 works well on both networks... although signal strength from the 900/1800 is stronger it makes no big difference... I believe the shorter band is essential in buildings etc. so wait till you get the phone and give it a try.
I tried the Band Switching application in the Special Edition ROM, it made no real difference.
Slightly off topic can someone point me to an explanation of UMTS???
I have just purchased a Gear s, which looks like it was purchased from the USA (T-mobile) & I am using it in the UK. It has been unlocked but when I put in the sim I do not get any single & within the call settings it displays unexpected response from network.
Any Ideas what could be wrong?
Thanks
Gear S is a dual-band phone only. So North America models won't work in rest of the world and vice versa. You are SOL.

Can you suggest where I might find out if my Australasian purchased Gear S + S4 will work in the UK?
Both devices bought outright (though so was my iPhone but the carrier still locked it into their service as soon as I put their sim card in)
To ask the question another way - if say travelling back to the uk (and assuming my devices are compatible with their networks ) - would I be better off prepurchasing a still quite expensive international package from the Australian bandits - or would an international package from Amaysim Lebara etc work with one their sims in the gear s and another in the galaxy device?
my provider is now offering slightly less extortionate international deals but as you say it depends on whether the GS is compatible with the other country's network.
I'd be happy to do that tap tap tap thing and just use the Gear S as a phone back in the uk
thanks
You need check Samsung for the specific frequency bands any of these specific local variants support. For Australia, it has networks use 850Mhz (which is one of the bands North America uses), 900 and 1800 (both are commonly used in rest of the world). So, I'm not sure what bands an Australian version supports.
Gear S for North America supports only 850MHz and 1900 MHz.
Gear S for rest of the world supports only 900Mhz and 1800 MHz.
Australia and Brazil have more complex frequency usage. So I don't have any idea. Japan is WCDMA 2100 only. So Japanese version contains no cell radio.
Thanks
I will get it exchanged
Best model for Western Australian users hoping to use it abroad
Gear S for North America supports only 850MHz and 1900 MHz.
Gear S for rest of the world supports only 900Mhz and 1800 MHz.

The somewhat-difficult-to-navigate Samsung Aus store is currently showing 2 different models
Telstra (900/2100) ----- GSM 900 DCS 1800 ---- 3G UMTS B1 (2100) B8 (900)
Optus Vodafone Virgin (850/2100) ----GSM 850 DCS 1800 ---- 3G UMTS B1 (2100) B5 (850)
Th Gear S still doesn't appear on the Telstra website ....(though it's their PAYG simcard in my watch)
but Optus is already offering the watch with a shared data plan
I bought mine from a 3rd party electronics reseller "**** Smith" but the Gear S has since disappeared from their store - go figure!
Thanks again for the ongoing education on battery considerations, pairing solutions, different types of network frequencies, and all your other helpful contributions
