I would like to thank the Moderators and all the members for making this site and forum so fun and informative.
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?

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.

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.

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,

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!

However, with our experience in the industry we have seen that almost every device launched in recent years within Europe has been ‘optimised’, with the American 850/1900 range locked down, leaving only 900/2100 for the rest of the world. As we are based in the UK it is for this reason we have taken the tentative step of advertising only these frequencies.

Speaking about release dates we do not have a specific one for the GT-i9100 in the USA but we can confirm the FFC has authorized the use of this particular smart phone on the 850MHz and 1900MHz GSM frequencies which means the first carrier to offer the Samsung Galaxy S II might be AT&T. These two frequencies account for the AT&T 3G network but they also match some Canada operator’s frequencies so there is a big chance the Galaxy S II will land there too in the near future.

That first link (that I provided earlier tonight I think) - read it to the end please, Clove has all the info on that page, just finish reading it. sorry for the tone , but I think you did not pay enough attention - there are comments to that blog post that say clove confirmed with the manufacturer and local distributor that all 4 bands are present.
I'm confused here
I have SGSII ordered from Clove. I plan to use it with ATT sim card. Have I made a mistake? Will I be able to use it? Do I need to cancel?
I hope it works well with AT&T since I intend to get this phone.
My current (imported) GT-i9000 did not properly support AT&T and has very poor call quality and call drop issues.
Sent from my Xoom using XDA Premium App
Although Clove originally said they doubted it would support 850/1900 3G+, they did later confirm their stock would be quad-band 3G. So no need to worry about support for NAM 3G.
Once someone get's the GS2 in USA on ATT, can you confirm that it indeed works on Edge AND 3G?

That's because the i9000 is only tri-band UMTS and only supports AT&T's 1900 frequency. When it gets to an area where the 1900 H/3G signal is weak, it can't switch over to the 850 UMTS simply because its hardware doesn't support it. So, then the phone call drops. You'll notice if you switch the i9000 to 2G/Edge, you'll never get a dropped call... because it's quad band GSM.
Also, ever notice you never get dropped calls when stationary and on H/3G? That's because with a solid 1900 UMTS signal, the i9000 will never search for the unsupported 850 band.
(And yes, I have confirmed all of this as I also own an i9000.)
i9100 supports quad-band UMTS with 850/1900 H/3G, so you will not have the frequent dropped calls anymore.
Here are the frequencies for AT&T: http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
So, the i9100 International will do almost all. Except LTE.

Thanks for your information.
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.
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 ?
Since Nokia does clearly say everywhere else except the US that 920 does support 1700Mhz (for obvious reasons), I wonder if the hardware in the AT&T version will be the same as in the int'l version and it'll just be a matter of unlocking the phone to use it on TMo.
Opinions?
I noticed that too!!
Its now PentaBand WCDMA/HSPA+ at 42Mbps. They added WCDMA 1700Mhz band on the specs.
Originally when the phone was announced last month was listed as QuadBand WCDMA missing the AWS band at 1700Mhz.
If this is true it means one of the following:
1.The band was always there and for some reason software locked and they decided unlock it and release it as a PendaBand.
2.They listen to the complaints (pretty much the same way they did and released the Cyan Color) as the missing AWS band was one the biggest complaints especially from T-Mobile USA subscribers and they decided to include it as well.
3.It is just a typo and Lumia 920 is still QuadBand HSPA.
4.It was a typo from the very beginning and Lumia 920 was always PentaBand.
Now assuming the the phone is PendaBand HSPA+ it will perfectly work with T-Mobile USA current 3G at AWS and with the reformed Network at 1900 they are preparing. It will work with both at 42Mbps speed.
The original unlocked Lumia 920 listed the following 5 LTE bands 800 / 1800 / 2600 / 900 / 2100.
If the unlocked phone comes with those LTE bands will be incompatible with T-Mobile USA upcoming 4G LTE network.
However the American model which AT&T will carry exclusively has the following LTE bands 700 / 850 / 1700 / 1900 / 2100
If Nokia also release an unlock/unbranded version of the American model with the above LTE bands and PentaBand HSPA+ this model along with the 42Mbps HSPA will also support T-Mobile's upcoming 4G LTE that coming mid of next year with theoretical speeds of 100Mbps.
Releasing this device will be the perfect option for T-Mobile subscribers as it will be future-proof for their upcoming LTE network.
I am curious to see whats really going on here. Meanwhile I am crossing my fingers. :good:
So Nokia needs to release a international us version?

Unlocked/Unbranded version of the American model is the correct way of putting it.
Nokia used to have to versions of the unlock devices in the past. The regular version which was usually the European/International model and the NAM versions for North America.
Many devices came like that in the past including the N95 & N95 NAM, 5800 & 5800 NAM, N97 & N97 NAM etc.
All had QuadBand GSM and different bands for 3G, the NAM versions had the American bands for AT&T USA and Rogers for Canada.
Now that PentaBand is standard for 3G/WCDMA, they need to release (and I hope this is the case) the European Model with the European LTE bands and a "NAM" model with the American LTE frequencies.
I guess time will tell what exactly the case is going to be.
But again this is for LTE. Assuming that the information on the spec-sheet is correct and the Lumia 920 comes with WCDMA/AWS 1700 then it will work perfectly with T-Mobile USA and AT&T's HSPA+ at 42Mpbs.

Unfortunatly number 3 is the correct answer.
According to WPCentral.com the AWS 1700Mhz WCDMA support for T-Mobile 3G that listed in specs are just a typo on the website.
If this is the case, you can still use the Lumia 920 under T-Mobile 3G at 1900Mhz.
T-Mobile is reforming their Network and releasing 3G to 1900Mhz now, the problem is that we do not know what markets/areas has this already or how fast the project is moving on and when it will get complete..

That's wrong, because this phone will be using the Snapdragon S4 Plus (MSM8960) which uses Software Defined Radio (SDR) for determining their bands. Obviously you cannot use all at the same time, but any one at any time. The HW supports this (according to the Qualcomm reference design), and if it hasn't been supported before in this chipset, it's probably due poor modem programming and/or unstable behavior, and/or band/bandwidth throttling by service providers networks. It's also an efficient way to make sure your Verizon mobile cannot use AT&T networks and vice verse...

That is why I said its Number 3, according to WPCentral. I am aware of the SDR in the latest generation of Snapdragons, however as its name mention its programmable, meaning they may have turn off the AWS...
For me it doesn't make any sense to list the phone originally with QuadBand WCDMA and then add AWS and list it as a PentaBand.
I mean if it is wrong and its missing the AWS that is making the original listing with QuadBand the correct one, so why they bother changing it?
In the other hand if the SDR scenario applies and the AWS is already there, they may just heard the complains and simply turned ON the AWS band, that is why they added in to the specs meanwhile the Nokia representative that WPCentral reached may not be aware of the new specs yet...
All these are different scenarios, unless we have an official clarification from Nokia, we cannot know for sure until Lumia 920 its been released.
PS. Can you post the link with the detailed specifications of the Snapdragon S4 detailing the SDR? The specs I found does not include any information regarding this. If I am not mistaken and remember correctly SDR is affecting LTE only and its able to catch from 700Mhz - 2600Mhz (for LTE), its programmable to deliver everything between these bands but limited to deliver 5 Bands at a time. I do not remember mentioning WCDMA to be compatible with the SDR, but I may be wrong on that. Please feel free to correct me if that's the case.
According to FCC documents, looks like AWS is there. Question... Will it be disabled in the AT&T version? Unlock possible?

I read that the FCC Documents for the AT&T model are mentioning AWS (1700) for LTE. This is normal as AT&T's LTE is operating also in AWS.
I didn't read anything regarding AWS for 3G/WCDMA.
If you read back, it specifically mentions wcdma 1700. Document differentiates between lte freqs and wcdma ones.
