Global 920 actually supports Tmobile frequecy?

[MrTofu]

An article earlier on wpcentral this month stated that Nokia claimed the listing of the 1700 band was in ''error'' for the global version of the 920. Yet it is still on their website. Nokia Lumia 920 Specifications - Nokia
Do you think this is an attempt to dissuade US buyers from purchasing a global unlocked version to run on Tmobile's network? Sounds like a stretch perhaps but I'm trying to see if there is ANYWAY i can get the 920 without switching from Tmo to ATT.

I too noticed that even though there is an "error" they never bothered to fix it, leading me to believe that they just want to hide it for exclusivity deals. Those deals are probably also why they hid the network setup app around the time the 900 came out.

I hope it does work for T-Mo so i'm just waiting til someone gets a hold of one.

I cant find the page that specifically breaks down global vs us Nokia flavors but IIRC, the global version has the 2100 band but not the 1700 band.

T-mobile and AT&T use both as LTE band 4, where 1700 is the uplink and 2100 is the downlink, so I dont think the global version will work on T-mobile.

Global version does not contain the 170mhz 3G band. Wpcentral already posted an article about this. It was a mistake on the Nokia website.

The 920 specs that are posted in each of the country-specific Nokia websites aren't always authoritative. The developers' spec page (whose link I got from the post AFTER this one) tells the real story. There are just two variants of Lumia 920; one has five band LTE, the other (AT&T version) has four. There is no magical 9-band device and no third model with a different combination of frequencies. <speculation>Note that LTE Band 4, which the AT&T version supports, uses 1700 and 2100, but likely only in combination, not as separate 1700 or 2100 bands.</speculation>

I think i have said this before here, but always look up the Nokia specs in the Nokia Developers page.

To keep hope alive for the 920 to work on mobile according to the fcc device test it was tested on the wcdma frequency so I really don't know what to think.. I think the device can support mobile but Nokia CANT admit it... someone has to take the plunge to let us know

 

[MrTofu]

I have confidence that a brave soul will come along and do just that! Either that or I'd be curious to see if anyone is going to try the unlocked global 920 and Straight Talk combo. I wonder if using that for a year or so until T-Mo refarms their network, then hopping back on with Magenta might be an option.

I have to admit, I'm trying to fight ending up being the first one among us to get one - and that's really only because I don't have that kind of cash to throw around at the moment!

Yeah, that's not the kind of cash one spends on an 'experiment.' I see your next choice of a phone states the Lumia 810. Are you just going to forget about the 920 for now and get the 810 as soon as it comes out?

 

[squire777]

A lot of guys on places like XDA and such have money to burn and go thru a lot of devices. Let one of them unlock it and wait for the results instead of spending the money right away and not being sure.

I'm actually still mulling about which one to get. Aside from how great the 920 is in general, I have my reasons for leaning toward getting it unlocked. The 810 also looks great, but I have a feeling I may have to get it at full price from T-Mobile even though I'm due for an upgrade. It all has to do with them eliminating the 200MB data plan, which is what I've got. Apparently, they're making people with grandfathered plans like me buy a new phone at full price and then go with a value plan. The value plan sounds fine, but the fact that I may not be able to keep my current plan really leaves a bad taste in my mouth. I've been thinking that if I have to buy a phone at full price, it might as well be the best one, hence the 920.

I also have an iPhone 4 which still only gets EDGE data speeds on T-Mo, so it wouldn't be that terrible for me to have a 920 with the same issue for a few months. That's of course assuming the refarming is done sooner rather than later. But I'm definitely still going back and forth about getting the 920 or 810.

Even the developer's spec page must be taken with a grain of salt since it doesn't list the AT&T model as having WCDMA band 4 (eg AWS), but the FCC tested the AT&T model with band 4 frequencies on both LTE *and* WCDMA. So unless they are disabling those frequencies in software specifically at AT&T's request..the "North American" model or whatever you want to call it is capable of both 3G and LTE on AWS.

I read these two posts on the XDA forum from some guys that know a little bit more about the technical details. Apparently the chipset (Snapdragon S4 Plus) defines the bands to use through software and so the AWS potential is there. Here is the actual quote:

...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...

here's a reply

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.

it's all very interesting and the more i read about it the more I'm sure the phone is AWS capable. It's just a matter of unlocking it to use those bands.

Seems to confirm that the "North American" version (FCC ID PYAA) does indeed support AWS according to the specifications printed on the box. I know that's not what the OP was wondering..but it's good to know that at least there's one avenue for getting a 920 on t-mobile (ie get a Rogers and/or AT&T phone and unlock it)
