As far as I can tell the nitro hd is a Qualcomm snapdragon s3 phone using Qualcomm mdm9200.
In the galaxy s2 lte forum people have gotten a AWS to work by flashing modem firmware from Tmobile galaxy S2 and even the HTC AWS phone with a mdm9200. I am wondering if anyone tried doing the same on this phone since it also apparently features the Qualcomm mdm9200.
What is AWS?
AWS is the spectrum T-Mobile uses 1700mhz uplink, 2100 downlink
How useful will this really be considering T-mobile is moving toward supporting 1900?
Canadian carriers such as Wind and Mobilicity, where you get unlimited canada wide everything for only $35 a month

Hey guys I was wondering if anyone knew what network modernization meant for us as phone buyers. I am really interested in picking up an S3, but want to continue to use my web2go/tzones plan. I was considering buying either an AT&T or international version and saw http://blog.t-mobile.com/2012/06/14/fast-progress-on-4g-network-modernization/ this article and was wondering the implications. Will the 1900 replace the 1700 in HSPA+? Does that mean phones that work on AT&T(1900/2100) will now work on Tmobile(1700/2100)?
Thanks for any info you guys can provide!
That is correct. Once the refarm is complete we will be able to use phones with the international att bands at full speeds on tmobile. 1700/2100 will be used for LTE

I would not get the AT&T or International version just yet. It is quite likely that you will experience slow speeds due to lack of proper frequency support at this time. Eventually T-Mobile's HSPA will be moved over to the 1900 band, however, this is a transition, not a on/off type of thing. There will still be HSPA on 1700 bands for well over a year from now, probably more like two. I think it will be a mix of 1900/1700 bands for HSPA in a couple of years, with LTE in the 1700 band exclusively. So, if you get the AT&T version now, you should hope that your city or region is one of the first for the transition, and don't plan to have good support while traveling. If you are on T-Mobile, you will have to choose great HSPA support now with no LTE ever (T-Mobile version), or no HSPA support now, and maybe some mixed LTE and HSPA support down the road (AT&T version; no LTE on International version).
I would personally get the T-Mobile version if I were you. LTE is not going away, and there will be plenty of LTE phones on T-Mobile in a couple of years. But HSPA has great speeds now, and will still have decent speeds in a couple of years.
The T-Mobile version already supports HSPA+ over 1900 MHz..so it's ready if you're planning on using it on Tmobile.
Just when I thought about dumping T-Mobile, looks like they might be heading in the right direction.

I just received my Note 2 it is on Rogers.
I have unlocked it but it is not yet rooted.
I have just traveled to US and am using my T-mobile SIM card and no matter what settings I try I can't get anything other than EDGE data even though I am paying for 4g.
I was under the impression that All models of the note 2 In North America (not including Verizon) were identical and would if unlocked work on all networks equally.
Seems this is not the case. The TMobile site lists different choice for the LTE bands than Rogers. Yet the Telus branded model on their website shows the same version of LTE as on Tmobile.
Are the phones actually different? Or is it the firmware of the Radio inside such that if I rooted and flashed the Tmobile modem it would then allow me to use the faster speed data network on my unlocked Rogers phone but on the T-mobile network?
No. Our model doesn't support the frequency that T-Mobile uses for 3G

Is it possible to flash the modem for Tmobile on ours and make it work?
I was under the impression all the phones in Canada were identical and yet the Telus one seems to have different LTE frequencies so maybe it just needs to be enabled as hardware not firmware supports it

No the hardware doesn't support it so a different modem wouldn't work. Our phones (Bell, Telus, Rogers) support LTE on 1700/2100, but not HSPA+, so until T-Mobile launches their LTE network you'll be on edge only
Edit: There are some areas where they are reforming their 1900 spectrum to HSPA+, so you could only connect in an area where they have done that already

So I guess for now I will stay on EDGE hopefully LTE goes live soon enough. The Rogers phone will work on their LTE frequencies right?
So I heard LTE is backwards compatible with GSM and HSDPA + My carrier supports AWS band 4. Will this work? Has anyone tried it?
So you're basically asking if the AT&T Optimus G will work with T-mobile's 4G Network, right? The answer is NO. Or at least not by default. That's because, even though the phone has the correct band (1700/2100), you would still need the correct radio to be able to use that specific frequency (again 1700/2100) with your carrier. Much like the AT&T Galaxy Note I717. It supports the 1700 frequency, but in order to have that working band with Tmobile, we had to flash a Tmobile specific baseband/radio from the Galaxy s2, Galaxy S Blaze 4G and/or Tmobile Galaxy Note to be able to use the phone on the 1700 freq. So in this case, Unfortunately, Tmobile won't be releasing the LG Optimus G, so there won't be any radios available to use. But, the LG NExus 4 actually has the exact hardware specs or SOC as the LG Optimus G, so a radio/baseband port might be possible.
I hope this post made sense to you.
So what is the difference than taking a locked phone, unlocking it to another network that shares the same GSM frequency?

Actually the two networks don't share the same GSM freq. Yes the AT&T LG Optimus G does have the AWS 1700 band in the hardware, but it is not enabled by default in the software. In order to enable the AWS 1700 freq, you'll need to use/flash the correct radio that carries the AWS 1700 freq. Like i said in the earlier post, one might be able to possibly port the a radio/baseband from the LG Nexus 4. Since it supports all pentaband frequencies.
So why would they disable it if the carrier uses 1700/2100 for LTE? I'm still not understanding its limitation
The carrier I want to bring it to uses AWS 1700/2100 3.5G.
Are they selling a phone that doesn't work with LTE on there network? Or can the phone only do 1700/2100 in LTE ?

It's not that the 1700/2100 bands are disabled. They are very much enabled but the radio is set to use them for LTE.
So you are saying even though LTE is backward compatible the band installed is software limiting the hardware to only allow LTE 1700/2100?

LTE phones are backwards compatible because they support other bands for HSPA and GSM. For example, a carrier using 1700 MHz for LTE may use 850 and 1900 for HSPA but the 1700 will only work with LTE.

You somewhat got it. It is the same problem with AT&T's HTC ONE X. The phone as the 1700 band for LTE, but when used with Tmo it only picks up 2G using the 1900 GSM. But with Tmo merging with Metro PCS, and partnering with Ericsson and Nokia Siemens Network, the H+ 1900 Spectrum will be available everywhere very soon. I read an article on tmonews.com that it should be done by the end of this year.
maybe the Canadian Telus version would work with T-Mo's AWS
it'll work you'll have to use the modem firmware from the N4 in order to use hspa+

i'll buy the att optimus g once this is confirmed working :good:
Any one got this one working? Got my Att OG, but edge is very slow. the T-Mo refarmed areas are OK though
when I go through the specs for the AT&T and Tmobile variants for the note 2, I come across a difference in the following
AT&T,
GSM Quad-band: 850/900/1800/1900 MHz
Tmobile
Frequencies and Data Type GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
What does the dual band mean? Is it for Tmobiles 4G network?
I thought all the Note 2's in the US had the same LTE radio
please shed some light,
thanks
1700 MHz/2100 MHz UMTS (WCDMA) AWS is currently T-Mobile's 4G network.
T-Mobile will have LTE up and running sometime within next year (2013).
Yes T-Mobile Galaxy Note 2 devices do have LTE. But it is now not activated. T-Mobile will activate the LTE within T-Mobile's Galaxy Note 2 when they get their LTE service up and running within your area.
How to activate the LTE and running on another carrier is a good question. This I get bits and pieces. But not a full step-by-step process yet.
The T-Mobile Note II is pentaband; it will work on AT&T and T-Mobile 3G/4G (not LTE though as of now). I think that's what you're getting at.

I believe that we can get the LTE up and running with other carriers. I know that I got LTE working on my GN2 (SGH-T889). We just need to learn how to get the LTE running with other carriers. That is really the question. When we figure that out then this might be able to be applied to other GN2 devices.
Tmobile hasnt turned on lte yet. From what i understand once they do our note 2's should be able to utilize it.

Tmobile uses 42.2 mbps dual channel hsdpa.
Afaik, At&t uses 21.1 mbps hsdpa.
Lte(long term evolution) is a different technology not yet active for Tmobile customers.
Real World, my friend with a Galaxy nexus on Tmobile network gets about 8mbps while I get 14mbps. Galaxy nexus has the 21.1mbps capable modem.

You're talking about something called DC-HSPA (Dual Channel/Carrier), which is basically what you said: Using 2 frequencies of HSPA(+) to achieve basically double the throughput.
Is it a hardware limitation (as in slightly modified Qualcomm LTE Chipset) in the AT&T Note 2 that 42mbps is not supported compared to T-Mobiles version? Or it is software / firmware-controlled?

It could be software (on the modem level, which is low-level stuff and separate from the ROM); T-Mobile's Galaxy S II was basically AT&T's Skyrocket with LTE disabled. You could actually flash a T-Mobile S2's modem onto a Skyrocket to get it to work on T-Mobile frequencies (but you can't get LTE enabled on the T-Mobile S II as far as I know).
would you say the note 2 from verizon is any better since it also includes a CDMA radio? Also, though LTE only works in the upper 700 frequency, any change a modem update or firmware change will allow the verizon version to work on T-mobile or AT&T network?

No; CDMA is useless unless you're going to be using it on the carrier it came from. I'd say the T-Mobile version is the best (in terms of working with the most networks), then the AT&T version (because it has LTE), then the International version (because it's the AT&T version without LTE), and after that the Verizon one because Sprint are jerks because they use "embedded SIMs".
Hello,
I'm in a dilemma where I have personal T-Mobile service, and AT&T service with my work. I want to purchase the variant of the S4 that will have the best compatibility with both networks (including HSPA, HSPA+, LTE). T-Mobile LTE has also already gone live in my market.
It seems the international i9505 support's T-Mobile's LTE bands (AWS 1700 / 2100 MHz LTE)
However, AT&T's variant (SGH-i337) supports AT&T's LTE (LTE 700 MHz Class 17)
Can anyone confirm if the international model also supports AT&T's LTE 700 MHz Class 17 Network?
Thanks!
From TMO spec sheets, it shows that it supports AT&T LTE bands. There are threads on this already.
