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 was wondering if there is any difference in HTC S740 and HTC S743? or is it one of those marketing scheme. S740 for Europe and S743 for USA?
When I go to www.gsmarena.com and type HTC S743, it shows the specifications for HTC S740.
Can someone please let me know? Thank you and I appreciate your time.
I think that the s743 does not have radio, but I'm not so sure about that.
Yes, FM radio is one. MAJOR difference is in support of different 3G networks frequencies - models with american band (900/2100 MHz) are usually introduced few months later after European versions working on 850/1900 MHz.
Using other words - European version will work in US but without broadband support and vice-versa.
Rose
The Bands are backwards
850/1900 are USA
900/2100 are Europe
Oops... ;-) You're right.
how aboun an s743 in europe?is it going to work?
I am looking to buy the HTC Hero on eBay but before I make the investment I like confirm the HTC Hero (model A6262) with HSPA/WCDMA 900/2100 frequencies will work on T-mobile USA 3G network. I read somewhere that Tmobile USA supports the 1700/2100 frequency band. Thanks for you input.
Will not work. 2G works fine, so you can make phone calls.
The topic has already been beaten to death. If you want to know the reasons do a forum search.
I currently have a telus HTC HERO in black but i am selling that one and buying a white HTC HERO.
The white HERO that im looking to buy is a european model.
I looked at the HTC website to see if there was any difference between the two phones and i found this:
HSDPA/WCDMA: 900/2100 MHz for Europe and 850/1900 MHz for USA.
So my question is will the european HERO work on canadian networks providers (FIDO, ROGERS)....would i have any issues with getting good signal connections and optimal speeds for 3G
thanks in advance
The Canadian GSM networks & AT&T in the US use a different 3G frequency than what GSM networks use in Europe & T-Mobile in the US. Due to this an European Hero on a Canadian network will not get 3G.
thank you for the quick reply.
I guess i will have to look for another seller.
Thanks again
Further, In Canada, networks like Bell and Telus are ONLY 3G, so without the North American 3G bands, you won't get any signal. I think Rogers has 2G, though. I'm not sure exactly which networks do and don't, but I know that at least some don't.

Umm, no....
As far as I know, the Bell and Telus joint network is 3G only. I don't know if the carriers have a deal to use EDGE from Rogers or areas not covered by 3G.
To the OP: Why don't you get a Hero from Telus? It's the same one as the European version, but works on the North American 3G band.

I dont like going on 3 year contracts so i buy my phones from resellers on craigslist. The seller specified that his HERO was from Europe so i wanted to find out if it would work. That was the only option at the moment but now I do have a Telus HERO that I bought from some other seller.
Thanks for the help btw.
Hi everyone. I am very new to this.
I am in Australia and Australia carriers (Telstra, Vodafone, Optus etc) have their HTC ONE model 801s. I am ordering the HTC ONE from UK which has the 801n.
Between 801n and 801s, the only thing i m concerned is the 850mhz HSPA/3G, which 801s has and 801n do not.
If I get the 801n, is there a way to make it able to work on the 850mhz HSPA/3G?
I m very new to this. So sorry if there is a thread for this, but I just doesn't know which one, as I saw people saying flashing ROM or Radio is the way to change it (like having 850mhz on the 801n).
Thanks in advance.
