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!

Doing a little research I was able to unlock my T-Mobile XDA and use a Cingular SIM.
Cingular is slated to turn on their 850mhz GSM in a matter of weeks if not days. I know that my T-Mobile uses 1900 mhz, so even with the Cingular SIM in place it is "piggy backing" on the T-Mobile towers. Even after the Cingular GSM network is online I will still be using T-Mobiles towers/network because of the 1900 mhz band constraints of my phone.
My question is this: is there currently or will there be (XDA II) an XDA that can use the 850mhz GSM band?
TIA
Ray
I noticed I knew little about this, so I figured this would be the case the case for most users outside of the Americas. I Googled around a little, the results are below.
Management summary: no, the XDA II will not support the 800-850 band. There will be a few quad-band phones, and some dual 800/1900.

GSM 850
(GSM 800)
GSM 850 is simply GSM technology operating in the Cellular (800 MHz / 850 MHz) frequency band. Both the technology and frequency band have been around for a long time, but only in 2002 were they combined.
In the U.S. prior to 2002, GSM technology only operated in the PCS (1900 MHz) frequency band.
GSM 850 addresses the needs of carriers with Cellular licenses switching from other technologies to GSM.
Before the existence of GSM 850, the Cellular band was commonly referred to as the "800 MHz" band. "850 MHz" implies a different frequency band, but this is not the case. "800 MHz" and "850 MHz" refer to the exact same frequency band. 850 is technically a more accurate description of the frequency range, but 800 is the original, and more common term.

By installing GSM at 800Mhz, all we're doing is reusing the same frequencies used for AMPS/TDMA and adding GSM to them. The US has always had 800Mhz for wireless services. Nothing strange about that since there have been wireless services in that band since the beginnings of cellular. The use of GSM at 800Mhz is nothing surprising and only a natural move for carriers who are licensed to use this band. There's no law saying that GSM should be confined to 1900Mhz in the US. Europe and the rest of the world have gone Dual Band on GSM (900/1800) a long time ago. Why can't the US do the same? Besides, it is not only Cingular and AT&T, the largest TDMA/GSM US operators, who are adopting GSM 800. There are many other carriers throughout the rest of the Americas, including Canada, who use the same US frequencies and are deploying GSM 800. GSM 800 will be just as necessary and as popular as TDMA/CDMA/Analog at 800Mhz. The market for GSM 800 is just as big as the TDMA 800 market since almost all TDMA operators are moving to GSM.
Dual band GSM 800/1900 phones will be the most common GSM phones in the US soon because single band 1900Mhz GSM phones will be good for T-Mobile only which is a 1900-only carrier in the US. Just think that Cingular and AT&T amass about 40 million users as opposed to T-Mobile's 10 Million. Also, quad-band GSM phones will be more common slowly but eventually. Nothing crazy about having 4 bands since the world has had 4 wireless bands for a long time, it's only that GSM had only made it to 3 of the 4 bands and now finally made it to the 4th. For starters, look at the Motorola V600 and the NEC 515 which are the first quad-band to my knowledge.
In the future, look for more bands as the wireless industry expands into 2100Mhz and 700Mhz. Finally, the US will see other types of tri-band GSM phones, such as those that will work on 800/1900 for the US and EITHER 900 OR 1800 for other regions.

Sorry I missed read the article but overall I'm only trying to help
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?

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???
Hey,
The T9193 version of the HD2 has the radio bands 850/2100 in it for HSDPA 3G speeds, but just the 850 band is needed to support AT&T's 3G service in the US.
Would it be possible to create a new radio ROM that disables/turns-off the 2100 band for U.S. users, since this band is useless anyway, and it may help extend the battery life of our HD2 by not having to power the 2100 section of the radio, especially if it makes any transmit attempts by the phone on the 2100 band (transmitting uses a lot more power then receiving).
Any chance of this?

T-mobile is also using HSPDA/3G @ 850 also and nowhere else? I hope so because pretty much half or better of the users of these forums are T-Mobile and *not* AT&T subscribers. Jus sayin.

ROM cooks do not have such fine grain control over radio bands.... Sorry.
I don't believe the T9193's radio has the 2100 Mhz band, otherwize I'd be able to use it in my area to get 3G coverage. (We only have Edge on the 850 Mhz band here)
Hopefully someone who knows for sure can answer this.

Hi mate,
you already tried this?
In Dialer > Menu (right soft-buttom) > Baseband > Band Frequency
or
Start > Settings > Personal Settings > Phone
But 850 Mhz is just for GSM not WCDMA... it's right?

I'm pretty sure the T9193 has the 2100 band, but 2100 is useless in the US because AT&T uses 850/1900 for 3G. The T9193 is an Australian phone made for Telstar (their cell phone company). The 3G bands used over there are 850/2100. So, because AT&T also uses the 850 band, thats why we are able to use this phone with AT&T's 3G here over in the US.
However, the 2100 band of the phone is useless in the US because is was intended to be used for 3G in australia.
The good news is that AT&T is phasing out the 1900 band for 3G and switching everything over to 850, so the HD2 will just get more and more 3G coverage as time goes on and then even the 1900 band won't be used anymore so it would be irrelevant if the HD2 has a 1900 band or a 2100 band because both would be useless.

Well, you neglected to say where "here" is
The best available combination for world-wide 3G access is 850/2100 Mhz. This is because:
1) 850Mhz is used in Canada, US, S Americas, Aus, S Africa for 3G broadcasting in regional areas (and in some city areas)
2) 2100Mhz is used in Asia, EU, Aus cities for 3G broadcasting
This is due to the actual physics of velocity = frequency x wavelength
Some telcos use 1900Mhz in the cities, but also broadcast in 850Mhz
Other telcos use 900Mhz in the regional areas, but also broadcast in 2100Mhz in the cities
ATT in the US uses 850mhz in the regionals and 1900Mhz in the cities. This ensures that "their" PDA's cannot use other SIM's - I have no idea why the dumbed-down US market meekly accepts that
The perfect combo is tri-frequency hardware, such as PDA manufacturers used to provide but do not any more (no excuses, it's just straight cost-cutting and sleight-of-hand marketing BS to suit the greedy telcos)
The HD2 released in Aus through Telstra is hardware-filtered for 2100/850 Mhz, the best available combo for world-wide use (not perfect, of course)
The HD2 released in EU/Asia is 2100/900 Mhz. This will access 3G in most cities world-wide (note that China uses 2100/850) but has limited coverage in regional areas - yes, I know there many 900 Mhz deployments but these are very limited geographically
The HD2 released in the US is 1900/850 Mhz. This is very limited for world-wide cities and excludes 3G coverage for those countries that use 2100/900 Mhz
None of this has any relation to GSM coverage, so please do not confuse them
Is the hardware actually different?
I live in NZ and unfortunately bought a T-Mobile unit which is set up for 1700/2100mHz which means that when in the cities I get full broadband, but in the regions I only get dial up speeds through GSM.
My question is does anyone know if the hardware could actually use the 900mhz broadband - or is it a pipe dream on my part that hopefully someone will release a ROM to access some previously hidden hardware?
I do recall with my Touch that there was a GPS built into the hardware that no-one was aware of for a year or two!

Hello everyone,
"The LTE standard can be used with many different frequency bands. In North America, 700 and 1700 MHz are planned to be used; 800, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; and 1800 MHz in Australia. As a result, phones from one country may not work in other countries. Users will need a multi-band capable phone for roaming internationally." (en.wikipedia.org)
So far, I have not heard of any LTE cell phone able to adapt to this multi-frequency international situation.
Even within the USA, it does not seem possible for an unlocked LTE cell phone which has been bought through one carrier to be used with another one.
Well, it should be possible !
After all, LTE is an international standard supporting all frequency bands, flexible bandwidth and both FDD and TDD duplexes ...
So it might not be that difficult to make these phones be able to use different LTE frequencies.
All radio systems can easily scan the whole spectrum in order to settle on the next available or desired channel. Another example, on Android Gingerbread phones :
"Settings-->Wireless & Networks-->Mobile Networks-->Network Operators--> Search Network" shows you all the mobile carriers available in your area, offering you the possibility to manually register on a specific network.
All this means that it should be technically possible to buy an unlocked LTE cell phone in the US for example, buy a sim card in another country where the LTE frequency is different, and everything should work fine, maybe with some software tweak.
Has anybody tried this already ?
