Hi, There
Can I update ROM so my siemens sx56 can be used in Asia, which have band 1800? Can anybody tell me what should I do so I can use that pc phone in Asia.
Thanks
No you can't. PW10B are 900/1900 only.
They do have 900 in Asia, more than 1800, so you should be OK.

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???
Hello,
In Europe HTC Aria can't connect to 3G network HSDPA 900 / 2100. In specification is described HSDPA 850 / 1900 (AT&T)
Is it possible radio ROM to unlock 3G Europe network ?
Than you!

No, there's nothing you can do about that.
I would love to be able to use this amazing phone in on T-Mobile in the US without crippled data speeds as well as seamlessly on voice. Anybody here have experience with this new phone on this network?
ST18a is supposed to be for AT&T, but I speculate that ST18i might be better for T-Mobile US due to 900/2100MHz. 1700MHz is missing though. I also don't know how accurate this is:
hxxp://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
Just today a T-Mobile Tier2 told me all I needed was 900 / 1800 / 1900MHz for 3G, and 1700 and 2100 for 4G.... so I am left very confused.
Note even access to 3G via roaming on this phone would be acceptable.
just to relieve you from misunderstanding, the ray is not 4G, and the bandwidth 2100 is 3G, and is used mostly in europe and asia pacific, which ever version you get, the umts is available in 5 bandwidth and are all 3G
Hi kms108,
What's your experience with the ST18i? Are you using it in the US? Possibly on T-Mobile?
Thanks!
i have the hong kong version, which is unbranded and using it in hong kong.
i'm liking it very well, just the right size to hold, not a android phone on the market to match it in quality, specs and size wise.
Xperia ray DOES NOT support 3G from Tmobile.
I own the device and I learned it the hard way.
Although ray supports 2100 MHz, the only device that can access Tmobile 3G is the one with BOTH 1700/2100 MHz. It is because Tmobile split both frequencies: one for download and the other for upload.
While for other carriers your phone will work in 3G if it supports either one of the frequencies, however, Tmobile is different.
Having said that, almost ALL of the unlocked phones in the market won't be capable of accessing Tmobile 3G.
If you wish to access 3G, the only carrier that will work is AT&T.

Which version, ST18a or ST18i, did you buy? See following:
hxxp://androidforums.com/sony-ericsson-xperia-ray/443709-3g-4g-us-t-mobile-using-st18a-st18i.html
Mine is the ST18i.
Well, neither version will support Tmobile 3G.
ST18i UMTS HSPA 900 (Band VIII), 2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
ST18a UMTS HSPA 800(Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
Here's the specs from the manual.
Since both are missing 1700, neither will be capable of receiving 3G from Tmobile.
AT&T
What irony -- maybe the AT&T acquisition of T-Mobile will have some benefits after all, especially those who buy the ST18a...
This wikipedia link confirms your experience: hxxp://en.wikipedia.org/wiki/T-Mobile_USA#3G_upgrade
The Xperia X10 had 1700, too bad Sony eliminated it.

Does this mean that the HK version can be used for AWS network such as Wind Mobile and T-mobile? I think the HK version is neither locked nor branded.

wow, the HK version supports north america LTE bands too....
I am wondering if I could get the Europe/Asia LTE bands on my Rogers Lumia 920
btw, The HK version is unlocked.
sure it does
if the box says 1700/2100 then it should support T-Mobile and Wind. I got mine unlocked from Rogers (with the stupid Rogers splash screen >_<), and it works perfectly on Wind, because on the box it specifies 1700/2100. People argue that those black 920s are the leftovers from Build, and got sent to carriers to sell, who knows. GL getting your pentaban 920 ^_^
Don't get to exited on the information on the Nokia website.
Exactly the same situation applies with the Nokia France and Germany websites. They do list the Nokia 920 with PentaBand 3G and 9 bands of LTE however the retail box for both the German and the France models only list QuadBand 3G and Pentaband LTE.
Until someone actually get one of those models and test them in USA or Canada we cannot tell whats the real deal with the Lumia 920 frequencies...
We can only hope this is true! And that it's firmware can be flashed on the Rogers one, and that would fix tethering issues etc.!!
So I bought a cheap Vitria, unlocked it so that I can use in Germany for a couple weeks. I looked up the Huawei bands supposed to do GSM 850, 900, 1800, 1900 and it is an LTE phone. I looked up Aldi Talk's LTE band is supposed to be 1800. That means I'll have no problems using this phone with Aldi LTE right? What about 3g?
