Developer unlocked Lumia 920 running on T-Mobile US with strong download speeds

TMobile Lumia 920

Windows Phone Central forum user KoukiFC3S has managed to get a Lumia 920 running on the T-Mobile US network (reportedly making use of 1700MHz). Purchasing the developer unlocked device online, it was possible for a new account to be created with the carrier and the device to be used with some promising results.

Publishing a number of screenshots on our forums, KoukiFC3S was able achieve download speeds just shy of 9Mb/s. The Lumia 920 speed test supplied is shown on the left in the image below, while our own 3G speed test on the Three UK network is on the right (using a HTC 8X).

Developer unlocked Lumia 920 running on T-Mobile US with strong download speeds


Is the same network, T- Mobile doesn't truly use 4G is all marketing they use DC-HSDPA 42 mbps, I am not sure y they are allowed to keep marketing as 4G when it really isn't .

Because 4G is speed to the consumer. Who cares about the way they get it. If it can download at the same speed or faster why not call it 4G. I laugh everytime I see that Verizon commercial with the graphs. They have nothing by T•Mobile. Yet in many areas Tmo is faster. Try the tmobile test drive and find out for yourself.

Oh wow really? I believed it lol, I was thinking of getting their pre-paid "4G" Service if I could get my hands on an Unlocked 920 but I'm on AT&T so it was just an idea once my contract finishes in order to save money...Ok now I'm confused...so it is 4G speeds? That would be great.

Its the speeds shown in the screenshot lol. If that's 4G to you, then yes it has 4G. Even LTE isn't up to the true 4G speeds yet (though I believe it has the potential). Tmobile is definitely holding their own.

Don't mistake T-Mobile's 4G for real 4G LTE. 4G is marketing, and if you've experienced 4G LTE, then T-Mobile's "4G" is blown out the window. T-Mobile's 4G only tops out at what Verizon or AT&T's 4G LTE can do at the minimum. You can regularly get speeds 3-5 times faster on 4G LTE.
Is T-Mobile 4G really 4G? From T-Mobile's marketing perspective, yes, it is. Its faster than plain old 3G, even though T-Mobile's 4G is technically a more advanced form of 3G. And at this point, with the other major network's on much faster and advanced technology, T-Mobile has to say they have 4G otherwise their network will just seem inferior (and it is) in comparison.

True. Most times my at&t lte will blow away others here in Vegas. But quite often my girlfriend's Radar will smoke my 900 & she's on Tmo.

Who says 4G has to be LTE? To me 4G is speed not technology. If tmo's "speed" can beat Verizon's "LTE" then I would rather have HSPA+ it's all about the speed who cares about how you get it. T-Mobile will have a nationwide LTE footprint by the end of 2013 anyway and it will be "LTE Advanced" using the latest category equipment.

They're allowed to because HSPA+, LTE, and WiMax (lol) were all deemed "4G" technologies by the ITU. The REAL 4G is much faster than today's LTE speeds.

Wait a second..i thought the unlocked version does not support T-Mobile's 1700MHz frequency, but the recently given by MS to developers did support the pentaband. So..this might be the one of those developer edition ones..
Edit: Or may be he is using it in a place where the refarming has been done..

Cool, I had actually read somewhere (may here itself) that even the Lumia 900 is pentaband but Nokia locked the frequency because of ATT.
I was on T-Mobile prepaid using the awesome 2GB data on my Radar 4G till I bought the Lumia 900 unlocked, had to move to ATT prepaid just to use the slow 3G :(
I wish T-Mobile refarms its frequency soon in Columbus so I can move back to T- Mobile

I live in one of those areas that the frequency has been re-purposed for 3g. I use my lumia 900. It registers as "4G" but the speed tests says its 3g. Either way, the speed is decent.

It has the band needed for LTE, but still lacks the band for tmobile 3g; until the refarm is complete, of course.

I may be misreading it, can you please tell me which band tmobile runs on for 3g? I may be forgetting.

UMTS (also refered to as WCDMA) is the 3G standard uses by AT&T and T-Mobile.
GSM is the 2G standard uses by AT&T and T-Mobile.
CDMA2000 1xEV-DO is the 3G standard uses by Verizon Wireless and Sprint.
CDMA2000 1X is the 2G standard uses by Verizon Wireless and Sprint.

That will take a long time to happen, may be another 6-12 months, by that time I might have moved on to the L810 from my current L900 or some other device from CES launch

For those of us who are lucky enough to live in the areas that do, it's great. I'm always switching phones and now I can use ATT phone with faster internet.

I was wondering if that 920 is actually running on 1900mhz instead of the 1700mhz. Some areas like Las Vegas already have that frequency.

The initial batch of L920s available from Rogers in Canada (also only available in black-if you can find one) definitely have the 1700 band, as well as being factory unlocked. There are users running them on WIND, Mobilicity, etc, which ONLY has access to AWS spectrum.

What's the avarage LTE speed in the US? Doesn't 8Mb/s translate to about 80M connection o.O
HSPA+ seems to be pretty good compared to LTE...
Nordic dude

Average LTE speed is between 15 and 20 Mbps depending on whether your on ATT PR Verizon. I'm on att and average about 20, hitting 25 pretty regularly and I have seen as high as 32

Looking at the screenshot you can get on T-Mobile 80Mbps? 4 times faster than ATT or Verizon  LTE.
And T-Mobile in the States doesn't even have LTE?

Thats going to take a while for reframing huh? I'm debating whether I should buy the 920 unlocked and run it on T-Mobile but if it doesn't support 3G, I guess I'm assed out lol.

My apologies for the c;oarse language Pootbutt, but did you not read the F'ing article!? Yes, it does run on TMobile's 3G. Also Pankaj above is incorrect.

Apparently you didn't read the article because it was a DEV UNLOCKED device used, which is why I asked. Maybe I should've added consumer unlocked version or whatever lol

Apparently you didn't do any research because the Nokia Lumia 920 from Rogers is NOT developer unlocked, but it work on WIND which is an AWS carrier.

Oh I see what you mean. Well the standard version in the US is the carrier version and that happens to belong to ATT so that answer is no. You'll need a non ATT model w/ the appropriate bands.

Can u tell me why am i incorrect? I m still standing on my point, that it wont work on the un-refarmed tmobile frequency (based on the specs on nokia's official site) unless the info on the site is wrong.

Ugh so confusing lol one guy saying it works, another saying it doesn't smh lol. The rogers phone, thats Canadian right? I'm here in Texas so I'm guessing maersk is right then ? If my deposit isn't bad on att I'll just get a contract lol

Yes, Rogers Wireless is a Canadian carrier.
Apparently, the first batch of the Nokia Lumia 920 that Rogers sell is carrier unlocked and works on T-Mobile's HSPA+.
Since AT&T hasn't started selling the Nokia Lumia 920, we have no idea if the one from AT&T will also work on T-Mobile HSPA+.

:) Lucky you, guys... Here in Croatia we must wait for a few more months, probably, before Lumia 920 gets here... Anyway, I see the screenshot option is being heavily used, that's good... :) Finally, eh? 

My question is I'm on wifi 80% of the time so does it really matter much if I get 4G or not on the L920 I'm on tmobile.

Well, if you use WiFi 80% of the time then it shouldn't really matter which network you are on, unless it sucks big time 20% of the time. I think buying Lumia 920 off-contract and using it on StraightTalk or Net10 Wireless (AT&T type SIM) maybe a viable option if you were thinking of using it on T-Mobile to save money due to T-Mobile's cheaper data/talk/text plans.
I have been using unlocked Lumia 800 (Europen version) on Net10 (AT&T SIM) and I constantly get 2-7Mbps speed (avg 5Mbps) where I live. It is more than sufficient to run any video on my phone. I pay around $46 for unlimited talk/text/web, I can even do tethering and watch videos on my computer (done only for testing). My point is, this plan is way cheaper than any T-Mobile plans and you don't have to worry about T-Mobile bands. That's my 2 cents.

I wonder how much fun you'll have when Net10 disconnects you for unauthorized tethering and excessive data use. Something you don't have to worry about on T-mobile.

Well, as I said, I did tethering just for testing but they don't seem to care if I keep browsing all day long. I don't watch videos on my phone too much but I do use my phone a lot for web browsing. I have used more than 10GB in a month with no problems (I checked it after I got "COUNTER" app from Nokia, before I didn't know how much I used to use). I just didn't want to disclose it, lol.

This is not correct. As I stated above, both unlocked phones (Euro and American) will work on tmobile US, but only with 2g. Though it has the necessary LTE bands, it lacks the GSM bands required to use tmobile's 3g.

As I stated above, the Nokia Lumia 920 from Canadian carrier Rogers Wireless does indeed support HSPA+ on the AWS band which means that it supports T-Mobile's HSPA+.

US At&t version lacks the 3g bands yes, although I would bet it is just disabled. European and Canadain versions have t-mobile's aws band though. Check the specs on the franch or candaian nokia site. see for yourself

Hi Rich or Jay or anyone that can help I'm having a problem posting from the app...Error msg is "error posting comment: bad authentication code. try logging in again. please try again." I've deleted the account info from settings content in the app.

I read this in the forums yesterday, which by the way is an awesome addition to the app. Good job fellas! I also read that it may work with Verizon's LTE 700 data band but not 1900 voice band. Not sure how true this but want nothing more than to have a 920 on my network. 822 is meh but not high end.

Yeah the 822 is ok but not all that the 920 is! I have the HTC 8x that was given out at the launch event its on att and is not bad but I really liked the 920's. I'm going to wait and see what the odyssey is going to be, before I use my upgrade on Verizon.

Duffau you are not understanding the T-Mobile refarm process. T-Mobile is refarming their 1900MHZ band to provide HSPA+ to unlocked ATT phones which do not have 1700/2100MHZ support. However, if a phone does support 1700/2100MHZ bands then it will automatically use that band on T-Mobile's network and get HSPA+. Since the L920 is pentaband and supports the 1700/2100MHZ bands then it will work on T-Mobile's network and get HSPA+ speeds. The refarm is only relevant to phones that do not have 1700/2100MHZ support.

While this in Brazil, i just have 15Mbps in a ADSL connection and stil need to pay around 50 dollars. HSDPA+ exist only in the metropolis and the average download speed in these are about 0,3MB/s. At least cost just 0,25 dollar cent/day

Well in wp8 its home+power but in w8 that combo = ctrl+alt+del. I have no doubt I can do this on my surface but been too lazy to look it up lol.

Great minds think alike... KoukiFC3S chooses the best phone in the world with an alternate OS (I want the 920, have a HD7), and he also chose the best car in the world with an alternate engine (I have a Zenki FC)... WP and RX7 owners unite!!! LOL

About the speeds - those are definitely nice speeds for mobile, h*ck I've only got 15mbps for cable internet at home.

Still wondering which carrier the Ativ S is landing on. Hopefully tmo will get it. Cant wait to test both the 8x and Ativ S.

Rich Edmonds, please update the article.
It has been conformed that the Nokia Lumia 920 from Canadian carrier Rogers does support HSPA+ on the 1700 Mhz band.
The developer handset is NOT unique in its ability to support HSPA+ on the 1700 Mhz AWS band.
A user from our forum has already conform that Rogers's version does work on T-Mobile HSPA+ network.

nice best just getting better

NOKIA LUMIA 920 black

Curious, I got mine this week at BUILD and I've had instances where the cell status in the top left would say "H+" as oppsed to "H" in the image above. 

The title should be changed to "Carrier unlocked Lumia 920 running on T-Mobile US with strong download speeds"
There's a different between carrier unlocked and developer unlocked.

LOL, here in Italy I have 5Mb/s in download, from my computer, using the ADSL.
So you're telling me that this phone on cellular network has twice the download speed I have with my desktop, and you even call it slow for your standards?
Loooooool :D
I wish my phone had even ¼ the speed of this 920 :P

I fail to see how this is impressive. I could get up to 32 Mb/s on 3g (h) here in Sweden, although the Lumia 800 only supports 14.4 Mb/s which I get most of the time. The speeds listed here I get when I have a crappy connection picking mushrooms in the woods.

I regularly get 28Mbps on ATT with my Lumia 900. Highest I've seen is 33.
This pales in comparison. T-Mobile gotta get that LTE!

If indeed non-US phones are readily supporting T-MoUS frequencies, then the AT&T exclusivity deal is beginning to look a little on the unfairly competitive side.

I searched online and found a tweet from AT&T confirming that the unlocked version will be $499.99. If this is true, will I be able to use it on T-Mobile?

does anyone know if a factory unlocked 920 (as opposed to carrier unlocked) will work on Verizon network?

The Developer Edition is going for $500-$700 on eBay, FWIW. Even more depending on the colour.
As for the AT&T phone, yes you can use it on T-Mobile. You won't get 3G/4G speeds unless you're in the new refarmed 1900 MHz areas. If not in those areas, it will use EDGE. But the phone will work. There are YouTube videos on how to unlock the device, FWIW.
As for Verizon, no clue. I'd imagine no. But hang tight, Verizon will be releasing an aluminum 920 variant called the 928 in April.
