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!

Anyone that got the s2 in canada, can you share where you ordered this phone from, please ? I really want so bad but can't find where to order.
From what i heard , this phone even if it europ, it will work with us and canada providers?
Thank you.
I got mine on Ebay.
The phone supports (GSM/GPRS/EDGE): 850, 900, 1800, and 1900 MHz
UMTS: 850, 900, 1900, and 2100 MHz bands.
Telus/Bell/Robbers/SaskTel/MTS use 1900 and 850 UMTS for 3G/4G/HSPA.
Don't know what bands the other providers use so I couldn't tell you if it would work on Wind, public,etc.
Hey,
So this phone works no problem in Canada? I'm on Rogers and I'm looking to buy an i9100 off the net.
Any idea if the NFC works?
Thanks
I'm on Rogers too. I ordered mine from Expansys on Friday...Fedex says it will be here tomorrow. Since Rogers uses the 850Mhz band for 3G/HSPA I'm sure it will work just fine.
I ordered mine from Expansys.ca

The current devices do NOT have NFC.
As for NFC in Canada? I suspect it will be a few years before Canada is NFC ready. Canada is usually pretty slow in adopting new technology.
Look how long it took Canada to finally roll out Chip and PIN debit/credit cards.
Even so, our Chip and Pin cards still have magnetic stripes on them for the merchants that haven't upgraded yet. Which means our brand new Chip & Pin cards can still be easily skimmed.
yup... you gonna just love this beast!!! have mine since two week now..and very satisfy of course!!
i"m on rogers....but would work on any gsm network in canada...even on telus!! they use simcard for their hspa+.....and i"m not sure but bell who is using cdma band offer simcard, so i presume some phone could work on their network??

Bell and Telus actually share the same HSPA+ infrastructure. They combined their resources to build it together
Ths SG2 will work on all of Canada's "big 3 Carriers" (and anybody that uses their network).
However, it won't work with Wind/Moblicity or anybody else that piggybacks off their network (well..you'll be stuck on 2G)
Title pretty much says it all. What's the real story on the the 3g frequencies? Nokia's site indicates it's quadband 3G, but yet many of the stores seem to indicate that it's tri-band for 3G. I would like to get one for use on ATT, but I definitely need 850MHz 3G since that is the predominant frequency in my area.
Anybody? What's the real answer on this?

Thanks for the responses everyone. I think they just add to the confusion on what the real answer is, or Nokia is producing multiple models with different frequencies which I've seen referenced elsewhere.
I might just hold off for the 900 or wait until CES in January where they are supposed to make their big splash for the U.S. market. The render of the Lumia 900 that hit wmpoweruser today certainly looks nice if it's true. I wouldn't mind a slightly larger screen if it doesn't make the device too large. Some of the current phones border on mini-tablet size!
I know of two types of Lumia 800's and you can differentiate them via their FCC identification.
The European edition, FCC ID: LJPRM-801:
GSM/EGSM : 850/900/1800/1900
WCDMA : 900/1900/2100
The North American edition, FCC ID: ...RM-819:
GSM/EGSM : 850/900/1800/1900
WCDMA : 850/1900/2100
I really wish Nokia would fix the data on their web pages. I ran into this a few years ago with another phone I purchased from them where it was advertised as having U.S. bands when in fact it did not. Thanks for the info everyone.
Agree 100%. When i bought my phone, the lumia was advertised as:
WCDMA: 850/900/1900/2100
Many sellers have since correctly identified which bands the phone supports, but some still falsely advertise both 850 and 900 bands being on the phone.
When my Lumia 800 arrived and I could only get Edge/G service, I did some research and I was slightly disappointed. Luckily I work and live in a Wi-Fi zone, so that is my primary data connnection.

You too, huh? I was curious about Rogers. I find that 2G isn't the end of the world.. Only shortcoming are media rich sites, otherwise they still load up quickly for me.
The only thing I really would have missed on 3G is mapping and navigation, but the non-data GPS and preloaded map feature has completely eliminated that concern.
Rogers here in the 'Peg. I'm in love with it even though the primary service around my home is Edge/G. However, since I wrote that piece above, I grabbed the "Nokia Network Setup" application from the marketplace and now I can get 3G around my workplace.
Here is my situation at the moment. I'm currently in the US using At&t's network through straight talk. I purchased the Nokia Lumia 800 the UK version which is LJPRM-801. It clearly states that it supports WCDMA 900/1900/2100. Which I suppose are really meant for the UK or Europe. When I purchased the phone from the seller he clearly stated it was lock and he got it from Orange UK. Which I assume is locked as well. Surprisingly when I received the phone I inserted the Sim and it registered perfectly fine. I get voice AND data. I figured it may possibly be using the 1900 band for data. My main thoughts about this UK version is it may possibly have the 850 band included but not listed on the box for regulation concerns. How would I go about and truly testing it out if it does support 850 band?
You can't really, short of going to an area you know uses soley 850Mhz 3G, and not 1900 as well.
I dont see the reasoning behind manufacturing two different phones, My thoughts are they could have just disabled the band with a simple firmware. Has Anyone truly tested this? Any though on getting a different firmware version of the Lumia 800 on this UK version seeing if it would enable the 850 band.
Me too I purchased one from Clove.co.uk. On the box it stated 900/1900/2100 for 3G but I have 3G. Maybe I have a 1900Mhz station near my work. I will do more tests tonight.
Does an app exist to know the current band of 3G connection?

When you say quad band are you referring to 2g or 3g? because we know it's quadband 2g, but whether it's quadband 3g is the question.
So I have used it on 3 different locations here in Montreal on Rogers and I always got 3G. I don't know the band used by Rogers. I found several references but not definitive answer. I have the Lumia 800 Model 801.

I'm in Germany right now and don't have the box. I don't remember if it had the cell bands on the box. I know I got hspa on AT&T and I was happy.
The reason is I ask is because when the 900 comes to the US im debating on getting an unlocked version on Tmobile or switching to AT&T for the Lumia 900. The reason for the switch to AT&T is because of the iphone 4S users at my job can pull 3G in areas where I dont get reception at all. What gives? A guy that I work with gave up his Titan that he loved for a 4S just because he can pull 3G in areas his Titan cant where I work. I feel thats fair enough. So im wondering why the iphone can pull 3G in areas the Titan cant on the same service and wondering will the Lumia 900 give me the same reception service as the iphone S? Not sure if anybody is in the position to test this out.
I found the reception to be great my wife has a Mozart on same network as my lumia and I still have a couple of bars of 3g when she has lost all signal, is in underground shops.

that sounds good. hopefully when i get the lumia it works everywhere my co workers 4s works. I wonder why it varies between devices on the same network? KI hear that the 4s has a dual antenna and it depends on what material the phone is made out of. Is this true?

No it's not true.
The fact is, Lumia 800 in theory supports 3g quad band (850,900,1900,2100 mhz) BUT only 900/1900/2100 are supported in current firmware releases.
You are getting signal from 1900 towers, an iphone 4s is getting signal also from 850 towers.
Titan, depending on version, may be in the same situation.
Lumia 900 will be, as HD7S, in an opposite situation: 850/900/1900, so it will work well in North and latin america and will not get good 3g signal in europe\asia\africa
You can get a good picture of the situation here

Does the frequency determine if u can get reception in hard to get places such as all concrete/block building or in heavily insulated basements. At my job its hard for anybody to get a good reception but it's rare for anyone to get 3g besides these guys that have high end smartphones

Quality of reception is determined by several factors:
1) Build quality of phone antenna and radio software
2) Distance from signaling tower. Different frequencies usually have different towers. Different hardware\software on the phone support different frequencies.
Of course good phones have good antennas (and lumia for example has a very good one), but if you read my links you will discover that in US you have a real mess in 3g umts phone frequencies comparing to the rest of the world and even between companies.
For example:
- T-mobile: 1700+2100
- At&t: 850+1900
- Verizon: totally different technology until they migrate to lte, however 1700 (that's the reason of manufacturers releasing few phones on this network and usually long after initial availability).
Mexico: 850 only
Latin america: like at&t, 850+1900
Australia: 850+2100
Rest of the world (europe, asia, oceania, africa, brazil): mainly 2100
So, antenna is important, frequency (and distance from tower) is even more important.

Cool thanks for the help, you really broke it down for me. As long as I hyave a good antenna in my phone, something better than this DVP on Tmobile in the Us, im good. Tmobile sucks in my area and im regretting getting their service. When I had ATT a few years back I didnt have much of a problem.
I just want something that can give me reception quality as close to the 4S in my area.
