So long story short, I'll lose my unlimited data if i switch to an LTE device and I really like the Lumia 900, the 800 is basically the 900 minus the LTE (and a smaller screen but whatever) but it also lacks the 3G 850 band.
Has anyone tried this phone stateside on AT&T, and if so did you get alright 3G coverage?
I've been using the UK unbranded Cyan 800 since Jan on AT&T in Seattle. I, too, am not willing to lose my unlimited data plan for $20/mth. Coverage is good. Would really love to have 850 3G coverage though, as the 1900 is spotty. It performs well though.
Do what you can to find an RM-819 device somewhere. You can spend an arm and a leg and get it from MSFT bundled with accy's. Or, you can import one from another country.
Awesome! Now if I could only find what band covers the western New York area I'd be half tempted to sell off my Radar
And thanks for the tip about the RM-819, just checked telus's site and it looks like their 800 supports the 850 band so I might not need to see which band covers my area

I, too, was looking for an RM-819 for a decent price, but I haven't had much trouble with the RM-801 in Austin on AT&T's 3G. Some places where I would normally have 3G, this phone gets EDGE, but that's an acceptable compromise for having this phone.
Just get one off Ebay they have plenty there and some are going for cheap
You can get an RM-801 or RM -819 on Amazon. Amazon doesn't tell you which one is which, but I bought both and returned one of them.
The one labelled "Nokia Lumia 800 black 16GB -FACTORY UNLOCKED" is an RM-801, and it's a German T-Mobile/Vodafone branded phone that has been unlocked. $439.99
The one labelled "Nokia Lumia 800 NK-800 Windows Unlocked Phone-International Version" is an RM-819 and it's an unbranded Puerto Rico variant, which is what I have. $491.88
Try omegacell.com.
They are in Alberta. The guy have quite a réputation. Bought mu rm-801 from Jim. Je do have rm-819 in stock now.
a word of warning
Remember that manufacturers are terrible at providing accurate statistics about their phones. Remember when Nokia's own website said 850 band was include? The same was true for newegg.com and plemix and many others. So regardless of which say 850 band is include understand that they're most likely wrong unless it is in the place of the 900 band. Or it specifically says rm819.
Another note, that htc radar will work on at&t if it is (A) unlocked and (B) the t-mobile usa model. The same is true for the Lumia 710. T-mobile was bad ass about that and included some of at&t's 3g bands.

How I unlock the Lumia 800 from puerto rico locked to Claro?
Sent from my HTC One X using Tapatalk 2
Just to be explicit here - there are TWO versions of he Lumia 800. RM-801 is the original European release. Microsoft now sells RM-819 in its Microsoft Stores, which adds the AT&T 850 band and does HSPA+ (which shows up on the phone as "4G").
Long story short: US buyers avoid the original model and insist on getting the RM-819 for AT&T use.

Hello, I just got this phone and I'm wondering if I was automatically switched to HSPA+ speed. It says H on the status bar but I don't notice any speed improvement. AT&T can't detect the phone obviously so I can't switch the 4G data plan on the website either.
Is there a way to check or make sure I'm getting HSPA+?
Thanks.
Go to the marketplace and download Free Speed Test.

If you are in an area that uses the 850 MHz band exclusively for HSPA+ and you only have a tri-band WCDMA Lumia then you will get 3g/edge speeds.
Data goes back and forth between 3G and H as I move about the city (New York). Wonder if it's the phone or the crappy AT&T signal.
My max down speed is about 3mbps.
Just wondering where you purchased your Lumia 800 from? I am looking for one for use with Telstra in Australia that uses the 850MHz band

I bought mine unlocked from Amazon.
Does it support the WCDMA 850MHz AT&T network? Did you have to flash it with something?
the Lumia 800 currently does not support 850Mhz, only 900.
Next month, the US variant (RM-819) will be released here at the Microsoft stores. I'm sure they won't be cheap, but they'll support 850Mhz. You can wait until then. There is also speculation that the EU variant (RM-801) can be flashed with the RM-819 firmware and then open up the 850 band, but that won't be confirmed until someone actually does it.

Sorry, I should have been more detailed.
The variant models of the Lumia 800 (RM-801 and RM-819) differ in WCDMA bands, not GSM bands. Take everything I said before and apply it to WCDMA/HSPA. It then matches up with the description from your German advert.

It's wrong. They're only tri-band 3G.
Edit: And that's already been mentioned, stupid extra page.
It uses the 1900 band to get at&t 3G, correct?
I was thinking about picking one of these up but was worried about 3G coverage with it if it only use 1900 instead of 850 and 1900.

So is anyone using it with at&t and getting 3G coverage?
Hello,
I am considering buying an unlocked Lumia 800, for both use on AT&T's network in the States and then abroad in the Middle East during the later half of the Summer. I have never bought an unlocked device before, so I just wanted to ask about the differences between the UK and US phones -- I believe electrical outlets are different between the two areas thus the need for an adapter -- and if I'll have any troubles popping out my SIM card with my current phone and switching between the two. Abroad, I've planned on getting a local plan in the city I'm visiting, so I don't expect any trouble there.
Regarding the Lumia 800, does anyone have an idea about the pricing and how it fluctuates? Full retail at sites like Expansys are about 700 USD, while others in Asia and Europe are hovering around 500-600 USD. Obviously, I've got around 6 months to wait, so I'm anticipating it coming down to a more palatable 400 USD.
Thanks for any advice.
Most sites that will export to US will include a power charger adaptor. I got a universal plug converter with my order. So, you won't need to worry about that.
Expansys is expensive. You can currently order the black from Amazon for 509.99. I ordered my Cyan from handtec.co.uk for 353GBP + 15 for shipping (about $584 USD). Depending on where you order the phone, you'll need to fill out paperwork for the FCC to approve the import. If you order from Amazon, this should already have been done, as the phone was already imported. Since I ordered directly from UK, I got a call from FedEx to fill out the forms while the plane was still in the air. Was the fastest shipping I'd ever seen. 36hrs from ordering from UK to receiving here in Seattle.
Be aware, also, that current versions of the Lumia 800 do not support the AT&T 850Mhz for 3G. For me, this is noticeable in my apartment, but nowhere else. If you wait a month or so, the US variant (RM-819) supporing WCDMA V (850MHz) will become available unlocked direct from Microsoft.
its 500 on amazon and comes with an adapter. newegg is $550 and works on 850 i ordered there and it came with the adapter.

Can you confirm that Newegg sells the variant that works on WCDMA 850? This isn't the same as GSM 850. They show the Lumia 800 as a deactivated item. And, when it was active, it show the same incorrect WCDMA bands as most other retailers out there.
Thanks for the quick responses. I didn't know about the incompatible 3G bands or the US version's upcoming release, so I'll wait and see if I can get a decent deal there. Also, newegg was shown as unavailable when I last checked.
I did just see the Lumia 900 was announced, with a release date pegged for March. My upgrade is sometime around May-July, so that may be for consideration. Only problem will be AT&T's policy on exclusive phones and mid-contract for unlocking phones. Hopefully, the homebrew scene gets more active as more users get onto the platform -- I'm thinking of a parallel with the iPhone jailbreak/unlocking bits from the iPhone Dev Team.
I'd wait until early February for them to be sold unlocked in Microsoft retail stores and online.
Should (hopefully) be cheaper than what it costs to import one currently. It's hard to wait though and I'm dying to get one. lol

Not so sure about that. It'll still be slightly exclusive for a bit. I also think that it's going to be bundled with a few other things.
I'm looking forward to the availability of the c-1031 sleeves that come with the phones. I'd like a spare cyan, and then one of each color, for the fun of it.

This is going to sound rude, but I don't believe it. It's already been admitted by many UK retailers that they posted the specs that Nokia has on their website, which are incorrect.
There are two versions of the Lumia 800. The EU Variant (RM-801), which is quad GSM and tri WCDMA 900/1900/2100; and a US variant (RM-819), which is also quad GSM, but tri WCDMA 850/900/1900. The US variant has not been released yet, neither has its firmware. There are quite a few people waiting on that firmware to see if it may open up 850 on the RM-801. That depends on if the devices are tri-band due to hardware limitations or firmware limitations.
This can be confirmed by referencing the outermost packaging that your Lumia came in. The one with the bar codes on it. What is the FCC ID line? I'll attach a photo of mine.
Given that AT&T uses a lot of the 1900 WCDMA bandwidth, you probably won't notice a difference between it and a 4s. Here's how I can tell the difference. I own a Nokia 6700 classic (tri WCDMA 900/1900/2100). I owned it before AT&T put out the HSPA upgrades and I got amazing reception in my apartment. After HSPA rolled out, my signal got really shotty and kept dropping out and down to 2G. I then got a Telstra HTC HD2 (850MHz). It functions perfectly in my apartment and does not drop down to 2G. I can tether at HSPA w/o needing to have my phone right up against the window in order to keep 3G signal.
Now that I have the Lumia 800 (RM-801), I cannot keep good 3G in my apartment, but 2G is fine. This means that the 850 band is the one that bends enough to get inside. The 1900 glances by.
I'm willing to bet that Newegg may have done what most other sellers did and just pasted the specs w/o verifying. After all, why would they need to, right? Nokia should have put out the correct information to start with.

Not true.
My Lumia is unlocked and unbranded. It was shipped directly from Nokia in Helsinki and I have that box too.
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:

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's wrong, because this phone will be using the Snapdragon S4 Plus (MSM8960) which uses Software Defined Radio (SDR) for determining their bands.

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.

So this may be a long shot, but I am wondering if any euro 920's will work on t-mobile US. I will beheading to Amsterdam in about 5 weeks and thought there might be a chance to get one there.
So, will a 920 from there work here on t-mobile?
If so, any advice on where to get one while I am there?
How much do they cost?
Thanks for the help!
As far as I know the EU Lumia 920 lacks support for T-Mobile's 1700 Mhz AWS Bands. As far as I remember there are Canadian carriers who have the 920 and are using 1700 Mhz AWS as well. The phone would still work but you would lack 3G/4G connectivity (given that 4G on T-Mob-US is not LTE but HSPA+). So I guess a european 920 is not that great of an option.
Thanks. Though a bummer. Darn T-mobile.

Hi all,
I see a few threads about folks trying to make lumia 920 work on Tmobile USA and I see some talk about quadband vs pentaband, which I am unable to follow. I am planning to buy an unlocked lumia 920 from expansys. I see they are selling unlocked lumia 920 for 450$ and for 550$. I am not sure what the difference is. Can the experts here take a look at the below links and let me know what the difference between the 2 models are and which one would work on Tmobile USA 3g and 4g bandwidths?

If someone could point me to some website (other than ebay) to buy an unlocked lumia 920 (yellow/red) which could be made to work with Tmobile USA, that would be really helpful!

Hi,
Well, I am not an expert but here's my two cents:
Quadband vs Pentaband refers to the bands the phone can work on. If you go to the technical specs on the pages you posted, you'll see this:
Network: GSM 850 / 900 / 1800 / 1900; HSDPA 850 / 900 / 1900 / 2100...which means that the phone has 4 (hence 'quad') bands in both GSM and HSDPA. In the case of a pentaband HSDPA, it also includes a fifth (and for you very important) band -1700 MHz.
Your last (and most expensive) option should work for sure, since it is a pentaband Rogers-branded model, even though the technical specifications do not mention the 1700 MHz frequency which is one of the two T-Mobile uses (the other one being 2100). But other vendors, including the one I've purchased my 2 Rogers-branded 920s from, do not list this frequency either, since they just take the info from one source and never bother to correct it when wrong.
The other (cheaper) options are most likely the ATT version, which does not have the 1700 MHz band, but technically can be flashed to Rogers and unlock this band (there's lots of info on this forum on how to do it). There's always a risk to brick the phone (render it unusable), but it's minimal. I guess it depends on your risk-management level, whether you feel comfortable enough to save $220 and carry all the process of flashing the phone, or shell out the full amount and have it working out of the box.
There's also the possibility that the cheaper ones do work on your area without flashing, depending on whether T-Mobile has already deployed the 1900 MHz band:
From: http://explore.t-mobile.com/phone-sim-card#faq
Will non-T-Mobile phones without the AWS 1700/2100 band not work on T-Mobile's 3G / 4G network?
A: T-Mobile provides 4G data services nationwide on the AWS 1700/2100 bands, and is in the process of adding service on the PCS 1900 band. Today, phones with both AWS 1700/2100 bands (not just one or the other) work nationwide on T-Mobile’s 4G network. PCS 1900 band phones (sold by AT&T and others) work on the T-Mobile 4G network in cities where 1900 service has been added. Check with your local T-Mobile store or call customer service to learn about the network status in your area.
You could also buy it from another place, more reasonably priced. This is where I bought my first one in December, and my second one a couple of weeks ago when I lost my first one Mind you, I did not buy either online, but actually went to their retail store to get them. Some people tend to think that they have a bad reputation, but my experience has been quite satisfactory (I bought the first one locked for $500, and they sold me the second one unlocked for the same price, virtually unlocking it for free). I do not know if they ship to the US, and if so, how much it costs but you could try contacting them... The downside is that they only have black. Here's the links:
$499: http://canadagsm.ca/NOKIA/Nokia-Lumia-920-Unlocked-Penta-band-lte/
$550: http://canadagsm.ca/NOKIA/Nokia-Lumia-920-LTE-Windows-8-Rogers/
You could buy the locked one and order an unlock code for about $15 on sites like cellunlocker.net
Attached is a pic of the box to show you that it does have the 1700 MHz frequency...

Thanks Abelitin for the detailed response. Appreciate your help!
I did go through some threads in this forum and it appears that flashing an Rogers version onto an unlocked ATT 920 involves so many steps that I got confused. Also I think there was one more thread about Nokia locking out the "navifirm" software that people use to get the different carrier versions.
In any case, after searching quite a bit, the cheapest I have found was in Negrielectronics and they are selling the Rogers version for 450 - 530$ range. Even ATT unlocked versions seem to fall in the same price range. So I might as well get the Rogers version.

Glad to help...
The cheapest variants on that website do no specify if they are Rogers, but the tech specs do mention they have the 1700 MHz band, so you should be ok.
Nokia did close access through Navifirm, but apparently it is still possible to flash using Nokia Care Suite, as per the post below...
http://forum.xda-developers.com/showpost.php?p=40988591&postcount=8
It is a simple but risky process, so if negrielectronics is selling an unlocked pentaband version for $450, that is the best option, imho.
Good luck in your quest. It's a great phone... You won't regret having purchased it! (Incidentally, my carrier also works on the 1700-2100 MHz frequencies. I was waiting for last September's iphone release, hoping it would add the 1700 band, but it didn't, so I then decided to get another Nokia (had had a 5230 for 1 1/2 years) and went for the Lumia 920. The very same day I lost it, Apple came out with a new version of the iphone 5 that does support the 1700 (therefore, it also works on T-Mobile), but now there is no way I go the iphone road, so I got another L920!)
