Can an At/T XDA I work on all three bands ,800/1800/1900?
Also what are the advantages that each band provides? ie. can one frequency reach a wider area...
they are the same as far as i know
but 900/1900 is only in us and some other places
and
900/1800 is only in eu and some other places
and no xda1 is only a dualband so it's 900/1800 or 900/1900
but xda2 is triband
GSM 900 is an older standard then 1800. When a phone is logged on to a 900MHz network it sends the dat with up to 2 watts, hile only sending with max. 1 watt in a 1800MHz network. As far as I know there are no special advantages/disadvantages of either. About 1900 I don´t know, since there is no such newtwork in Germany.
Can the XDA I work on all three bands if the band changer program is used?
will it work with the at/t, orange and tmobile?
qD
not 100% sure if the bandswitcher works or if the hardware is locked to one or the other
will it work with the at/t, orange and tmobile?

like a normal phone it will work on any cellphone company which ofer gsm
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.
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?

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???
HI
This might be already posted being new to this form. I need help I purchased XDA model above from UK from ebay the phone is unlocked. After browsing i notice XDAPW10B is made for the states. Well I didn't do my homework before i purchased cingular is 1900 band which is my carrier. MY XDAPW10A is 900/1800 Band which i didn't realized ontil after sale. Can I flash rom to change where it will work on cingular band? what are my choices. Please help anyone
There was a file as part of the Special Edition ROM that could tell the software to switch between 900/1900 and 900/1800 however it wouldnt actually work as the hardware is different.
Affraid you cant use that model as a phone in the US
Stot
Thanks friend i was afraid that will be the case i will just resell on uk ebay
Hello everyone ... I bought a Moto E XT1524 in Spain. The phone works on 3G bands 900 and 2100. In Argentina, the country where I live now, the 3G bands are 850/1900. Because of this my phone only works in 2G. Looking I found this post http://forum.xda-developers.com/moto-g/general/unlock-hspa-bands-moto-g-1700mhz-xt1032-t2878441 that explaining how to unlock bands. The question is whether you know if the phone will have this possibility. I mean, if the chipset supports these bands and doing the procedure will fix my problem. Or definitely is a limitation of hardware.
Thanks!!!
I assume that the hardware is the same between phones, and that the radio bands are set by firmware. If I'm right about this, you would need to flash firmware on your phone that supported the bands that you want. However I am only guessing about this.
