So whenever I'm in a call on my T-Mobile Note II, it drops LTE and drops to HSPA, is there any reason for this? I was under the assumption that the Note II can do SVLTE

The T-Mobile note II doesn't have its own dedicated LTE antenna like basic sy every other phone besides the iPhone 5? Why did Samsung choose to make the Note II like this and why cant I find anything on the internet about it? Seems this should be as easy to find out as the I phone's flaw with LTE. But again, why did Samsung choose to make it this way? Especially when ALL of their other LTE phones support SVLTE?
Oh, and what's your source? I'd like to read up on this not-so-publicised flaw.
You do realize every other LTE device right now drops to either HSPA or CDMA while utilizing voice functions? I have had many, many LTE devices and can verify this.

My Verizon Galaxy Nexus, DROID RAZR M, HTC Rezound and, HTC Thunderbolt, all did SVLTE. The iPhone 5 is the only device where the internet made it well known that it is incapable of doing SVLTE because the vast majority of devices devices are capable of it. I mean, if most weren't, then no one would've made a big deal about the iPhone 5 not doing it. Cause that would be hypocritical.

Seeing how Verizon does not have voice over LTE, and as far as I know, no one does since the only way to implement it is extremely costly right now, i highly doubt you had voice over LTE. Your Verizon phones used voice over cdma, and data over LTE, allowing both at the same time. This is why LTE sucks your battery dry on Verizon. It is running two radios at once. Since LTE is an evolution of gsm there is no need for two radios and so you see better battery life at a loss of LTE data while in call.

I said SVLTE, not VOLTE. SVLTE is Simultaneous Voice + LTE while VoLTE is Voice-over LTE.
And on GSM phones that have LTE, they run 2 radios as well. One for LTE or HSPA and one for GSM. As you said, no one is using VoLTE yet. And our GSM/LTE phones need to maintain a connection to GSM even when connected to LTE so that we can still make calls and send/recieve texts.
Theres your proof bud. Just because it isnt what you want to hear doesnt mean its not the reality of the situation.

Okay to be honest I'm not 100% sure about the number of radios, fairly certain (~75%) only one radio is needed (the 7105 based note 2s have 2 radios, the dormant SoC radio and the GSM/HSPA/LTE radio). I do know you don't drop to GSM for calls, you drop to UMTS otherwise known as WCDMA and can hand off to GSM if needed.
There are plenty of areas with no GSM coverage but have UMTS/HSPA coverage. All these radios are evolutions of GSM and can have VoWHATEVER just no one has done VoLTE or VoHSPA, except T-Mobile has rolled out VoHSPA since the beginning of this year).
This is why your battery will take a hit on HSPA or LTE but not nearly as much as on a CDMA phone.
You are right in that most applications (barring tmobile now) use circuit switched GSM/UMTS for voice, not packet switched UMTS/HSPA/LTE.

Oh I can tell my battery takes a hit on LTE! Much more than when I was on Verizon! I just attributed it to the weak signal though.
But you're saying most LTE/GSM phones fall back to HSPA if they were on LTE? I didn't know that. Please excuse my ignorance

You can do this on the Thunderbolt in 3G only areas too. I think because HTC used 2 radios or somesuch. The Nexus can not do Data/voice in 3G only areas.

Verizon 4G devices still have to use 3G for voice at least until VoLTE is switched on next year. Having two radios always on is part of the reason why the Verizon version has such horrible battery life.

I hope when 3G is turned off that simultaneous voice/data isnt lost!!
I think there is alot more to it then having two radios on. Isn't 1x a radio? I've never followed radio technology so I really dont know all the details, but I'm pretty sure the 4G radio itself can do voice/data as well as support 3G and 1x as well. I dont think every 4G handset contains both 3G and 4G chips. I may be wrong, but it seems a bit of wasted space!

3g for vzw isnt getting shut off for sometime (i think like 2014). its verizons major voice backbone.
1x uses the same chip as 3g and every LTE handset has 2 radios.

You won't lose it. Voice is treated like just another data type in LTE which means VoLTE inherently supports concurrent voice/data.

It's about having radios on at the same time. LTE/UMTS/GSM does not run 2 radios simultaneously and supports seamless in-session handovers including the signaling of mobile terminated calls (LTE release 9). It is almost effectively the same as concurrent voice and data in UMTS/GSM. In LTE/CDMA you run both radios concurrently unless you turn LTE off.
I've got a photon that I can fall back on but I hugely prefer my JB-powered gnex... just trying to understand if it is compatible with the networks in India (Mumbai specifically).

I'm not even sure what the network is because this isn't anything I had to buy a SIM card for... I just turned the phone on and it popped up "Mumbai" on the screen, showed full strength (with the "R" by the bars for roaming), and sent me a text message saying voice was $2.49/min, incoming text is $0.05 and outgoing is $0.50 and data is $0.008/kb. I just used 3G watchdog to turn off mobile data completely. The guys here tell me that CDMA and GSM are both built up everywhere. It's pretty crazy to be driving in a cab through an area where people aren't even wearing shoes and there's stray dogs running through the street and I have 5 bars of signal. Yet back in the US I have 1-2 half the time... dammit Sprint really sucks.

Thanks. I thought you changed the sim card to use it on one of the Indian networks. They do have good coverage in Urban areas both CDMA and GSM. I noticed that last year when I went there and my OG droid came up with a signal and an R just like yours. I did not use it however because of the high rates.
T-Mobile Galaxy Note II Passes Through The FCC, Is Future Proofed With LTE
http://www.tmonews.com/2012/09/t-mo...s-through-the-fcc-is-future-proofed-with-lte/
850/1900 GSM/GPRS/EDGE, 850/1700/1900 WCDMA/HSPA, Band 4 (5, 10, 15, 20 MHz), 17 LTE (5, 10 MHz).
Yup, that’s both 700 MHz for LTE roaming and 1700 MHz (T-Mobile’s AWS band) for LTE, which means only one thing — the Galaxy Note II is future proofed for T-Mobile’s LTE network, coming in 2013.
The rest of the report is under confidentiality so there isn’t a whole lot else we can discover from the FCC filings, but at this point the presence of LTE was the only unknown we had hoped to find. The rest of the Note II is pretty standard globally so we don’t expect any more surprises. To be honest, with the discovery of LTE on board, we can’t think of any better surprises.
While it’s true my excitement of LTE and future-proofing may be preliminary, the Galaxy Note II is likely to be a device many of you consider to be the best of both the tablet and smartphone world. The knowledge that the device will be ready and waiting for T-Mobile’s LTE network to go live in 2013 and won’t require a new piece of hardware is just a little bit of comfort in a world where hardware turns over far faster than our upgrade dates.
Cool...but. I'll be using my Note 3 by the time you see LTE on your Note 2
No need to wait for LTE, HSPA+ for now is just as fast if not faster in places. As far as getting LTE it adds/keeps value when time comes to resale the device.

Even if it's true that T-Mobile is slow in adopting LTE, I'm still happy with their service because they are the only carrier that provide WiFi Calling. This is very important for me since no carrier has any signal inside my apartment unit, and also while travelling overseas. If not for the WiFi Calling feature built into T-Mo's phones firmware, I would have already bought the international version with or without LTE. I've been very happy with my Galaxy S3 on T-Mo without LTE, but I want the bigger screen and S-Pen. Eagerly waiting for the US launch. Only a few more days! I'm sure I'll have a Note 3 as well! Lol, I just got my S3 and I'm already looking at Note 2.

For wifi calling use Talkatone and your Gvoice account if you have limited minutes on t-mobile. It's unlimited incoming and outgoing over wifi or 3g. And you have the benefit of having a second number to give out.

Has anyone tried slipping an At&t LTE micro sim (dirty i know), into the Tmo Note2?
I know we're all supposedly waiting for an update to the radio firmware but can't hurt to ask.
None of my friends have an LTE microsim phone.
I've been seeing a lot of LTE buzz going around in the tmo GN2 forums and I want to get some clarification.
My understanding is that there are two versions of the T-Mobile Galaxy Note II: SGH-T889 and the SGH-T889V, with the latter being LTE-enabled. I have the SGH-T889. The buzz leads me to believe that the regular SGH-T889 does have dormant LTE capabilities which can be activated by flashing the newest radio. Is this true? Or is it only the SGH-T889V that has LTE?
I purchased this phone fully expecting zero LTE capability. All I really wanted was ~15Mbps, and HSPA+ typically delivers between 13-18Mbps depending on recenption in my area, so I'm pretty satisfied. However, I believe T-Mobile does have LTE in my area, so if my phone does have LTE capabilities that can be activated, that would be a nice bonus.

I find that hard to believe. Again, San Jose is suppose to have LTE, and it has been reported to reach Fremont, which is 20 minutes from where I live in (North) San Jose.
One thing I've noticed, if I have the LTE option enabled, I'll lose all data connection after the phone sleeps a while. In order to restore data, I have disable LTE, and reset the radio (enable then disable Airplane mode).
I'm fairly convinced it's a software bug or configuration issue, but I suppose I could be in an LTE dead-zone. I also doubt that, since I live in a fairly open area, and cell phone reception has never been an issue for me, not CDMA, GSM, HSPA, or WiMAX, which was notorious for spotty reception. Not to mention, according to OpenSignal, it works down the street from where I live.

Just because they say you have LTE in your area doesn't mean it's fully up and operational just yet. T-mobile is still working on getting ALL the towers upgraded for LTE. Give it time and you'll probably see LTE start popping up more and more.
And before you make comments about how they should have been prepared blah blah blah; go check the LTE thread because it's been done MANY times.
I read there are some issues with the Galaxy S6 and some newer phones on Verizon being unable to do native simultaneous voice + data. I think because of a limit of the # of radios and/or antennas. What can we expect with the 5X on VZW? Thank you!
All new phones can do simultaneous voice and data only with VoLTE or while connected to WiFi. When connected to LTE (and no VoLTE) or 3G data they will drop to CDMA 1X if a call comes in. This is because they only have one antenna pathway and one radio. If they had a separate radio for LTE (like done older phones) it would drain battery almost twice as fast since mobile connection is one of your larger battery users.

Any time LTE is on the second would have to be on, or it wouldn't be able to seamlessly take the call, so that wouldn't have worked.
If your call isn't very long navigation would still work fine, it caches a bit in case of signal drop. The other option would be to download the route ahead of time, Google can do it now I think.
I have a feeling it should have VoLTE though, which would give you voice and data.

Will the same limitations be on each carrier (ie. if I switch to AT&T I still need to use VoLTE for simultaneous voice + data)? Thank you!!

Nope, the way GSM and CDMA works are different. Say you don't have VoLTE and are on an LTE connection. The tower also has a spot for you on HSPDA and GSM if on Tmo or AT&T, or on CDMA if on Sprint or Verizon. If you get a call you fallback to HSPDA or GSM. A similar thing happens on CDMA. The difference is CDMA can't do voice and data on the same connection, GSM and HSPDA can do both.

Really wish phones included a Ev radio so this would not be an issue. I wonder if the voice quality/codec on AT&T has improved over the years? Last I used them their voice quality was far inferior to VZW. May be time to consider a carrier switch.
I've not had problems with voice quality, the few times I call on AT&T. They weren't as good as Sprint (their new network has simply amazing voice quality, and data was OK lol).
Mostly I use Google voice via hangouts to make calls, so the network data is more important then voice quality.

All new phones can do simultaneous voice and data only with VoLTE or while connected to WiFi. When connected to LTE (and no VoLTE) or 3G data they will drop to CDMA 1X if a call comes in. This is because they only have one antenna pathway and one radio. If they had a separate radio for LTE (like done older phones) it would drain battery almost twice as fast since mobile connection is one of your larger battery users.

How new? My S4 gets simultaneous voice/data on lte, but not on 3g. Are you sure you're right about this?
Well, the S4 is not a new phone. And yes I'm certain without advanced calling (or VoLTE) you will not have voice and data on LTE at the same time.

Something I'm just realizing...I have a lot of friends and offices that have cell phone amplifier / extender systems that only repeat 3G not LTE. With no 3G radio this phone will be only able to do 1x for voice/data?! I think its also crazy that pure data devices such as the MiFi/personal hotspots still include ability to do EvDo Rev A yet phones don't!

The S4 had extra antennas unlike the newer phones because of VoLTE. The S4 had both radios on at the same time which eats more battery on a call with VoLTE you have improved battery life during a call and do both at the same time. The move was intentional to save costs as well as battery life in the long run.

I just got my Nexus 5X up and running on verizon. With my Galaxy Nexus I was about to take a phone call while tethering, but can't do that on this phone. Is there a fix for this? It's kind of a bummer because I tether often and take phone calls.
Edit: (12/18/2015) I figured it out. Chatted with VZW tech support to enable HD voice feature, and made sure "enhanced LTE mode" was on in settings. Voice+Data work simultaneously now!
Update: (1/19/2016) I have still intermittently had issues with simultaneously voice+data. I started to wonder if it could depend on who you are calling or what tower you are connected to. I powered down my phone and pulled the sim card for a few seconds, then rebooted and it worked again.
