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???
I just purchased a SG SII here in the US and later found out it is a UK phone (the sales rep said it was a US model)
anyway, the phone works great EXCEPT it will not log onto T-Mobiles 3G network. All I get is EDGE which is terrible.
How can I get it to go to 3G?
Spoke with T-Mobile, even got a new sim card. No help
Spoke wth Samsung US - they tried, could not help and then said to contact the UK.
Called Samsung UK and they said it should work, if not, bring it back as it is broken!
anyway, is there some sort of settings that I can change to make it work in the US.
I also need it to work in Brazil as I will be going there and will be using the Brazilian Tim network and installing their sim card.
thank you for your assistance in advance.
The phone is suppose to be:
HSPA+ 21Mbps/ HSUPA 5.76Mbps
EDGE/ GPRS Class 12
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
Did you limit the phone to only work with 2G in the settings?
Check Wireless Network settings.
Much more better would be goto Settings->About phone, tell us what Baseband, and Kernel, and ROM version you are using.
Reboot phone.

Exactly, that phone will never work on T-Mobile USA 3G network, refund it or switch to AT&T. Makes you wish someone would regulate mobile networks here.
Edit: SGS2 should work fine on TIM Brazil.
you guys are absolutely certain that this phone will not work on T-Mobile?
what about certainty that it will work on Tim? I live in Brazil and defintely need it to work there.
Here, in the US, when I return next year, I can alway switch over to AT+T.
I need to be certain because if I get to brazil and it does not work, I am screwed because then it is almost impossible to get anything done to it.
BTW- they have been saying that t-mobile will have this same phone in a few months. How will that one be able to work? will it be possible to flash that info to this phone when it comes out?
thanks

The US T-mobile Variant is completely different from the UK model, won't be the same. Also it's true you can never get 3G with T-Mobile, don't know anything about TIM though.
T-Mobile uses the 1700 AWS band which this phone does not use so yes... You will NEVER get 3g or HSPA+ with T-Mobile U.S.
From Wikipedia's list of UMTS frequencies:
TIM Brasil Brazil 2008 April 850/2100

The phone will work fine for you in Brazil.

so when you say fine, the phone, 3g to get to the internet, etc etc will all work?
as it is here, the phone works great and when with wi-fi, the internet is great but EDGE sucks ass.
So, as I already know that I am beating the dead horse. 3G here with T-Mobile is never going to happen but it will work with AT+T, in Brazil, the phone for calls will work fine, 3G will also work fine too.
does anyone know about claro, vivo or oi in brazil? just wondering....
and what about other carriers in the US, will it work with anyone beside AT+T?
thanks again. this has been very useful!
EDGE runs on GPRS. Your phone matches TIM's UMTS frequencies so it will have 3G data on that network.

I do not get that, some sort of inside joke?
Why would you buy a phone without checking on what radio bands it works , its not like US has only one provider they all have different bands/frequencies.

as I said in my first post, I was told it was a US version phone. HENCE, I figured it would work in the US.
I buy unlocked phones as I am in Brazil 9 months a year and Cali 3 months a year so I can not be under contract.
but thanks for the help on this.

so if I have been schooled properly. T-Mobile uses 1700 and 2100, so without the 1700 band, it wont work!
I guess I got to talk with AT+T
will any other carrier in the US support this?????
thanks again to all who have helped....

And it does work in US ON AT&T. T-Mobile is only a minor carrier.
So it is your fault.

it seems that only T-Mobile and a few Canadian carriers (and cincinati bell) use the 1700 network! I wonder why?
they need to join the rest of the world and get on board with 2100!

Hey guys...
Someone is offering me a LG L9 from T-Mobile. Just a quick question, this specific model has the 850 MHz band for 3G? I have been reading online and in some places states it does and some other states it doesn't, so I'm kind of confuse right now.
Appreciate your help. Thanks...

Model P769
The device is a Quad-Band hspa device.
according to most sites with specs for this phone here are the bands it supports. Note that you will need to sim unlock it through T-Mobile/Ebay if you wish to put a non-T-Mobile/T-Mobile MVNO sim in the device.
GSM 850/900/1800/1900
UMTS/HSPA 850/1700/1900/2100
Thanks kevev. Regards...
Hi there- I've moved to a country where the LTE is on band 3, or 1800 mhz. I know that with some phones, firmware updates/flashes enable frequencies not previously available. Is there such a thing for the AT&T HTC One? I thought there might be, given some editions of the One support 1800, so I thought maybe it was a dumb artificial limitation imposed by AT&T.
This country also has a "TD-LTE" freq of 2300, but I'm afraid I'm not sure what that is.
Thanks in advance for any help!

HI im also having the same problam i think the Tmobile LTE works on 1900 but here in sri lanka its 1800... have u found any solutions??
im desperately looking for one...
one suggestion that may work is install an ATT rom and and unlock ur device maywork
Hi, despite the availability of the International 4g version of the X1 [7d-501L] in italy, that has all the LTE bands that I need, I bought the chinese 4g variant [7D-503L] in order to receive more and quicker updates.
Now, AFAIK the two versions are indentical in hardware, could a developer extract a modem from the international version and make it a flashable zip that we can put on our chinese 4g variants?
This way we could have the chinese 4g version with all the latest ROMs, but still enjoy FDD-LTE in Europe and rest of the world.
Sorry but it is not correct. The international version has a modem with only fdd frequencies, while the chinese version has fdd AND tdd. So, different modem.
You can search this area and you will find at least two others who have tried to do this, unsuccessfully!
I meant that the chinese version has a ton of TDD bands and only 2 FDD bands. Yes the modem is different, but I believe the difference is in software, not in actual hardware.
Hello you can flash 501l firmware on 503l device without any issue, for me. But I think hardware are not the same, 800mhz fdd LTE band is not present on 503l.

I don't need that. I bought 503L to have all the latest rom, it wouldn't make sense to flash an older firmware. Yes 800 mhz is not present on 503L but I *strongly* suspect that it is disabled by software.
I really think that 501L and 503L are the same, the only thing being that Huawei enables certain bands on one, and other bands on the other one.
Yes I understand and it would be great. But when I flash 501l, I should have 501l modem? Maybe it is a hardware switch?

I agree with you that hardware wise, all the different variations of the X1 are identical. Difference is software/firmware based. The difference is located in a partition that is usually not flashed by a ROM update. I successfully did this with my AT&T Samsung Note 2 and unlocked TMo AWS bands with the help of XDA instructions.
To assist you, I came across this website/blog that has instructions on how to unlock FDD bands on 503L. I have not tried it; I live in the US, even unlocking the FDD bands, I will not get LTE (main US LTE Bands are 2,4,17)

Maybe the modems are different after all.
