[Q] AT&T 920 on T-Mobile with 3G? - Nokia Lumia 920

I've had an HTC HD7 on T-Mobile for a good solid three years now, but it has become outdated and I need a new phone.
All the Windows Phones on T-Mobile are very crappy (in my opinion) and the phone I would love to have would be the Lumia 920.
My only problem is, it doesn't exist. My question is: If I were to buy a Lumia 920 locked to AT&T off of eBay, then get an unlock code, would it be possible to have it running with at least 3G speeds? All the radio frequencies point to yes, but I would like to check here first.
Thanks!

if you read around, all at&t lumias 820 & 920 are locked. there is a rare rare chance of getting an unlock code from AT&T. All the sites in the web are scams. It would be better to buy a Rogers Unlocked 920 because: 1. they have the same antennas as AT&T, some say the phones are pentaband and 2. they are already unlocked.
or get an international unlocked. some reports stated you can flash the firmware from other countries and get AWS.
Long story short, unless you want straight talk which is powered by AT&T, you wont have a good chance of getting an AT&T lumia sim unlocked
hope i am wrong. working on getting a code or two time will tell

google search my friend, anyways ebay is good, like other stated, craigslist but rare. negri electronics, expansys. there is a canadian retailer that sells them and ships them to the USA, but in the long run buying new and out of country will cost you a shinnier penny than at AT&T

Bought mine at canadagsm.ca and had it in my hands 3 days later in Miami. And, so far is the best phone I've owned. It is a pentaband so it will work with T-MOBILE. Also, I have none of the problems others are mentionning on this forum (dust in front of the FFC, etc ...).
SO, I'm very satisfied !!!

Realized that there are two threads...I'm pasting my reply here and requesting the other to be deleted.
---------------------------------------------------------------------------------------------------------------------------------
I'm on T-Mobile as well. I ended up purchasing a Lumia 920 international unlocked (Polish variant). The international variant uses the same 3G frequency as the AT&T variant (1900 MHz 3G).
T-Mobile has been refarming their network and they are now running 3G on 1900 MHz as well, in addition to the original 1700 MHz.
If you're in the Mill Creek, WA area, I can't tell you how the 1900 MHz 3G network performs since I'm not in that area. However, I live in Bellevue, go to UW and work in Shoreline and 3G coverage on the 1900 MHz network has been pretty good. At UW, I can get anywhere between 7-15 Mbit/sec.
To answer your question, yes an AT&T version will have 3G on T-Mobile's network, but only if you're in an area that has received refarming.
Hope this helps. Feel free to send any more questions my way!

Good luck as right now they don't exist. The sites claiming to have them are scams. Those claiming to have received one are most likely working for or being paid by those same scam sites.

This is true. Do NOT give your money to any site claiming to unlock the AT&T 920. It will only be possible for those sites to do so after May 9th, and then still only buy it from reputable sites!
The ONLY way to unlock an AT&T 920 is if you're an AT&T customer and push really hard with the customer support. It might also be only customers with accounts on business discounts (tied to your work email) that are able to get it. I get premier business customer support when I call in to AT&T and I even had to argue on the phone for 60 minutes in total with all the reps I talked to before I was able to get them to submit an unlock request.

[Q] Unlocked UK Lumia 800, for an American

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.

My box looks nothing like that and doesn't have any of those markings. That is a Nokia lumia 800 box for a carrier. I also have had phones that don't support 850 and I don't get 3g/4g on them. I do on this phone

Our stickers may look different, because I have the Cyan version.
According to Nokia customer care, and many other articles online, your device does not have 850MHz. The product code is RM-801.

I have the black from Amazon's intial selling - so spent low $600s but haven't looked back.
The box DID include a USA outlet adaptor.
If you're on ATT, you still have a good shot of getting 3G if you're in a major area.

Of course there's a US variant. It's getting released possibly next month.
Why the product codes are mentioned is so that people can confirm that sellers are indeed selling the right bands as they quote. There is no quad band WCDMA Lumia 800 until you can prove otherwise. There is no information on your device that contradicts anything that I've already quoted.

Come on those links you posted are before it was announced. I have the 850 variant because that is the band in my area. You don't because you have the UK model that was released unlocked for the UK. Until you can provide information other than hearsay that there is no 850 then your just spreading rumor.
---------- Post added at 09:24 PM ---------- Previous post was at 09:05 PM ----------
I called Nokia after getting the number off of twitter and there are variants that have the 850 wcdma that are unlocked. I gave them my imei number and my phone is from Norway which has the 850 band. You can check the country specific website and they list the correct bands.

Nokia Lumia 710 from Rogers Pentaband?

Sorry, about posting this on the Lumia 800 forum but there doesn't seem to be a 710 forum. Anyway, my question is that there seems to be some rumor that the Lumia 710 being sold by Rogers is pentaband. There is a video of it unlocked and working with Wind. I'm wondering if anyone here can really confirm if it does support all the 3G bands. If so it seems like a really nice deal as they sell it for $250 no contract there and around $300 on Negri/Expensys. Thanks.
be careful
I am having problems with the Lumia 710 I bought! I have it unlocked to work on Mobilicity and it works, however, there is a problem with the phone where any case I put on the phone causes an echo with the other caller Im calling. The other side here's an echo on their phone and it is the Lumia that is the problem. Stupid Rogers store is not willing to take it back and exchange it because I unlocked it! This is crazy, even customer service gives me the work around. Im gonna try Nokia and see what they can do, but I would advise you to buy it somewhere else even though its more expensive, otherwise you can get screwed like me.
Take the case off.....
My wife has the same phone and has a case on hers and sounds just fine.
Now the 1st one sounded horrific without a case, but exchanged it out hassle free.

I can confirm the Rogers Lumia 710 is pentaband!
I unlocked it and using it on Mobilicity. Yes you can buy off contract for $254.99 plus taxes.
The Rogers website is not showing correct frequencies, but use this website as confirmation.
http://www.gsmarena.com/nokia_lumia_710-4276.php
Hope that helps ! I would imagine anyone on WIND and Mobilicity reading this will be quite happy. Also AT&T users would be happy too as the T-Mobile version is not pentaband but since Rogers and AT&T use same frequencies the Rogers Lumia 710 is pretty much a slam dunk. It would still need unlocking but that can be had online for $9. Also note this phone is a microSIM phone so a sim cutter would be needed. Most phone shops will do that for you if you ask.
Thank you very much! That is an awesome deal for a pentaband phone. Only thing missing and a front facing camera.
Yes... but the price point can't be beat. For front facing camera we will have to wait for the Lumia 900. Hopefully they make that with Pentaband frequencies. Worst case is they will make a model/version for T-Mobile and those of us on WIND and Mobilicity can use those. Or would would WIND and Mobilicity be smart enough to bring that phone into the line up? Let's hope so!
Rogers unlock
@PaullikesWINMO
Hi, just wondering how the quality of Lumia on Mobilicity is? Read other places that drops signal / slow to regain signal. Have you had that issue?
Thanks!
Sorry... I didn't see this post. So far so good. I have not expirienced dropped calls or anything. I'm primarily in north end of suburbs and quite often north of the area coverage and still get Mobilicity connection. Even when in Stouffville !

[Q] Giving Up

All i want is to go to a website, buy a Nokia 920, pop in my sim and use the phone.
i have gotten so confused and frustrated trying to figure out which one will work on the Bell network with the proper LTE frequencies....arrgggg
does anyone know where i can go and buy a RED 920 unlocked that suppose the correct BELL frequencies.
please help before i go buy a HTC 8X or worse yet an Iphone
Well hope you don't give up to easy. According to the wiki page for Bell Mobility they use 850 and 1900 MHZ. Just google "wiki bell mobility" I didn't think there is much variation between Nokia Lumia 920s but I guess there is when it comes to LTE ability.

thanks for the reply, i had a look at the site, they have the 920 LTE locked and 920 OEM unlocked. i would like the 920 oem unlocked version, but i am so confused about frequencies needed for Bell and the LTE to work
do i have to buy a rogers phone and unlock it to get LTE, and if i do that it says on that site that mobile hotspot won't work.
what the heck was nokia thinking with the rogers and att exclusivity deals.

Can someone help me find a lumia 920?

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?

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:

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!)

[Q] Lumia 920 Pentaband?

I'm confused in regards to conflicting information in regards to whether the 920 will run on both AT&T and T-Mobile's HSPA networks. I keep reading the phone is a pentaband and will run on both networks once the device is subsidy unlocked. Do we know for a fact that is the case? Finally, is what makes the Developer's Edition different the fact that it comes already factory subsidy unlocked to start with?
The ATT version of the Lumia 920, is not pentaband, the Rogers Canadian version IS though, it's pentaband for 3g and LTE, I can confirm as im currently running one on T-mobile and getting LTE and 4g HSPA

I have the at&t version of the 920, unlocked through their web request page. I'm not sure if it will answer your question, but in the Oklahoma City metro area where t-mobile has rolled out LTE, I get LTE and fall back on either 4G or edge. It usually stays in LTE unless I'm deep inside a building. Speeds are very nice at 15-20 down, 5-15 up.

I went to Canadagsm.ca and pulled up their Nokia phones and right out of the blocks the first phone pictured is the Lumia 920 "Pentaband" Unlocked for C$399 and the Rogers locked for C$375. But if the AT&T version is unlocked is it pentaband too?

I'm trying to get a definitive answer in regards to whether if the 920 is unlocked it is in fact pentaband. I don't expect an AT&T subsidy locked 920 to be pentaband. Where we live we will never have 4G LTE but recently AT&T did upgrade PCS1900 from 2G to 3G HSPA+ and we also use Straight Talk which even if we had 4G LTE; 3G HSPA+ is all we'll get anyway. I do appreciate the reply; thank you!
