WiFi Calling GREAT on new ROM T989UVKL1

Having used UMA on a hardware UMA-enabled phone extensively, and then the crappy laggy software on an earlier Android ... this new WiFi calling ROCKS!!!! No lag, seems great so far

I've questions about this WIFI calling feature. I know that it's unlimited and that it will not be applied towards our normal daily minutes.
My questions are, can you make WIFI calls even if you are receiving excellent tmobile signals? So say I'm at home with wifi connected and have excellent tmobile signal, then I make a call which will it use? Or if I have WIFI calling turned on, it will automatically make my calls using wifi instead of regular tmobile?
Just trying to get an understanding.

It's up to you. If you enable wifi calling, it'll use the wifi network. If you have it turned off, it'll use cellular radio. You don't have to have a weak signal to use it. All wifi calling does is turn off the cellular radio, and route everything through wifi. (It's a good battery saver as well.) If you're in an area that has no signal or very low, it's even more useful. I use it at work and at home. (At work, I get next to no signal at all. All tmobile phones i've used suck in my office. At home I get 15mbit dl speed on 4g, but I still use wifi calling sometimes there as well.)
Also, it DOES count towards your minutes, it's not unlimited unless you have a plan that will allow you to take advantage of the offer they have going right now. (Sadly, I don't.)

hmmm, that's not what I was told by the tmobile rep (just spoke to one of them). They said that wifi calling is unlimited and it will not go towards my 1000 anytime minutes. Now I'm starting to wonder if they knew what they are talking about.

If they are offering you the promotion where it's unlimited, then it is. However if you have an older plan, you can't get the promotion. So unless you get that, it counts towards your minutes. (Hell it even says so right in the app when it's run)

I just got off the phone again with another tmobile rep.
Here is what she said.
1. Your phone will use WIFI calling as long as you have wifi calling enabled on the phone and that you have connection to a router.
2. Will it use your whenever minutes? DEPENDS. if you have the newer plan (like i do, the 1000 whenever family time minutes), then it will NOT be counted towards my whenever minutes, thus I have unlimited wifi calling (GREAT!).
3. If you are under an old plan, then it MIGHT be counted towards your whenever minutes. so i say contact them and ask.
Thus, mstrk242 is right in all aspect. I guess its time for me to update my phone.

If you have free wifi calling in your account (see pic) then it won't count toward your minutes. I have the new plan but have to call to ask them add free wifi service to my account.

[Q] Anyone else have Wifi received calls drop after 1:26

Has anyone else noticed that received wifi calls drop after exactly 1 minute 26 seconds? Outbound calls don't seem to have the problem, only inbound. I thought I was crazy at first, but it seems others are experiencing the same behavior. If you Google "t-mobile galaxy note 3 1:26", the first result is a posting on the T-Mobile support site reporting exactly this problem. From that posting, it appears that this does not happen on T-Mo to T-Mo calls. So far, I can reproduce this problem 100% of the time and it is always exactly 1:26.
I have called into T-Mobile and started a trouble ticket and should hear back in a day or two, but I wanted to see if this is a universal problem with Note 3/T-Mo and the best place I could think of to check on that was XDA.
Please test when possible and respond if you are also experiencing this issue.
Thank you!

FYI note 3 users, WIFI signal is not stable in Note 3....

Agreed. I keep getting WiFi disconnects and a message pop up saying my WiFi connection is unstable. Wrong. My WiFi is fine and works on all my other devices just great. I have LTE at home and unlimited data so I don't even turn WiFi on anymore.

I'm not getting any messages about wifi being unstable. It's been working very well. It is only on received calls when in Wifi Calling mode. The calls drop after exactly 1:26, every time. The post on the T-Mobile support site has added 2-3 more people who are having the same problem. Can't seem to find a commonality among the the affected except that it is always 1:26, always on inbound wifi calling calls from non-T-Mobile numbers, and seems to only happen in this way on the T-Mobile Note 3.
If anyone could give it a test, I would appreciate it. Just call your Note 3 from a non-T-Mobile device while in Wifi calling mode and see how long it takes to drop the call (if it does at all).

I just had this happen to me today at work. Three incoming calls from my wife, all dropped at 1:25, 1:26, 1:27.
I'm wondering if this is only on stock ROM's. I'm rooted and don't remember having this issue before rooting.
I wonder if a custom ROM will help... ;o) Not that I really need another reason to try one.

I also have the issue with the dropped wifi calls, I know its not my network as my S4 works perfectly

I noticed some wifi calling issues. I wasn't that it was dropping at a specific time though. I would dial the number and it would sit there doing nothing. It wasn't stock either. I was on MyRom. Strange. Wifi signal is great btw.

I don't get many calls like that but now that you mention it (not to mention it just happened 5x in a row) I had it happen on mine and the gf's phone as well...
need this shiz fixed
link to T-mobile thread?
did you ever hear anything back?

My house has horrible signal so I rely on the wifi calling so yes this issue needs to be resolved asap

I am having dropped calls not only with wifi calling but also with regular calls.

Tmo rep rold me there is an update coming soon to address the wifi calling issues. Not sure if she was being truthful but that what she said.
N3 anticipating Tweaked perfection

I have this issue as well. Seems others have narrowed down its circumstances.

This is so frustrating & we have yet to get a fix.

I have the same issue expect my carrier is verizon.

I haven't had any issue with wifi connection, even when the call drops it stays connected, its just that it disconnects.
I've noticed frequent random disconnects on t-mobile to t-mobile wifi calling as well but not as easily time-able.

Any updates?
Anyone have an progress on this?
I have the same problem as everyone else. 1:26 every incoming call. Bam... dropped.
Very frustrating, especially with how reliable it was on the S4.
Anyway, hopefully we'll see a fix in the first T-Mobile update.
I've also subscribed to the T-Mobile thread, though I expect this thread to be my first answer...
Luke

Same here and another co worker with the note 3 is having the same issues, opened a support ticket with tmobile so lets see where it goes ...nowhere more than likely
---------- Post added at 12:00 PM ---------- Previous post was at 11:30 AM ----------
So after some testing im finding when using google voice number the calls will drop. When i get called on my tmobile number on either wifi or cell the call is solid, but if it comes through the google voice number it will drop every time.

[Q] Tmobile Note 3 on ATT network?

Anyone else running a Tmobile Note 3 on the AT&T network? Is there any difference in reception or LTE? I've seen in other threads people complain that they dropped calls and had less reception with the Tmobile hardware on ATT, I'd be curious to see DB measurements and not simply rely on the reception bars. Also heard complaints that the Tmobile N3 doesn't hand onto ATT LTE signals well.
Also using the Tmobile Note 3 on the ATT network does;
1) does tethering still work?
2) does it work with an AT&T microcell?

My wife and I both use straight talk which runs off of AT&T towers and when I'm at the house I have full bars and my speed was 20 if I remember correctly, at work I get 3-4 bars but never any reception problems. Hope this helps a Lil bit.

I'm running my N900T on AT&T with CM 11 and have noticed that my phone randomly drops back to Edge and even G sometimes. It has completely lost data access occasionally too. I put my phone in airplane mode and it goes back to full LTE, but that's bothering me. I don't know how to fix it.

You can download Advanced Signal Status. Then go to additional info then device info and you can change the network mode to LTE only to force it to reconnect to LTE always.

I tested the app here, and although it says my LTE signal is at 100%, my data connection is being disabled every time I make a call. I tried changing the preferred network type to LTE only in the phone info menu and calls drop as soon as I hit the call button on the dialer. Also, in the phone info menu, the option to enable/disable data shows only as "enable" during a call, which means data is disabled, and clicking it does nothing. As soon as I hang up, my data connection restarts and goes to 2G. I don't know if this is a problem with CM 11, so I'll try a Touchwiz ROM in a minute. Any other suggestions?

No problems at all with touchwiz. Probably a CM11 problem.

[Q] How to disable 2G radio (voice)?

Anyone know how I can disable the 2G radio? I am using an LTE/3G data-only sim with IP calling, so have no need for 2G. In battery stats I get a solid red line for mobile networks, as the phone is always searching for a voice network unless I put it in airplane mode (no good because I need mobile 3G/4G data). I would like to restrict the radio to only 3G/LTE if possible. I have root and xposed.

You should be able to do it from the service menu. Sorry I don't know the dialer code but I'm sure I've seen it mentioned in one of these threads (I access it through 3c toolbox.)

I found the services menu, but that just sets preferred data network, same as you can do under mobile networks in regular settings. It doesn't result in disabling the 2G voice (as if the phone were an LTE capable tablet).

Have you tried the lte only setting?

Yeah, it restricts my data connection to 4G, but still get red bar for mobile network in battery stats and mobile standby stats report 100% no connection, so seems like it still searches for voice service.

You could try posting a request for someone to build an xposed module in this thread. You never know it might spark someone's interest.

Hello, I posted in Project T Kernel thread about battery drain and network signal search. The problem is that the phone is continuously using the cell network even when in airplane mode and no sim is present in both trays. I also get the same solid red line of continuous activity use of cellullar antenna. What does your battery stats details look with airplane mode on?

With airplane on it shows no mobile connection, as it should.

Solved
After some net trawling, found a thread on an English language Japan tech forum about the problems of using data-only MNVO sims on Android phones. It linked to some Japanese tech blog site with a datasimpatcher exposed module. Installed the module and BINGO! Now getting green for mobile connection in battery stats. Hopefully this will have a positive effect on my battery life.
Link to patch, in case anyone else uses a data-only sim:
http://www.akaitori.info/datasim_patcher.apk?attredirects=0

Interesting, it should use less battery since mobile net signal bar is empty. Mine is full even without sim and in airplane mode, red bar means searching for signal and that modem power is on. How did you make the fix work? I don't see an option for zenfone 2, only samsung, htc, etc I installed but cellular network still full red line.
How you completely turn off cellular modem?

Turning on airplane mode should turn off your cellular radio completely. Strange that it doesn't. Regarding the patch, I simply installed it, turned on the module in xposed installer and rebooted. I left it in patch mode 0, which seems to work.

I still get a red line in battery stats. How did you manage to get rid of that?
@corrsea I bought 3c toolbox but I can't find the service menu option. Any idea?

Open battery manager in 3c. The middle button at the bottom of the screen is called tests. It opens the menu.

I deleted dialer&related stuff so it will fc -.- I only use VoiP. Do you get empty bars in cell network of battery details section?
Look at my earlier pic, modem always searching for signal (red=low signal or searching) even with no sim and airplane mode on. Some device's modem can be physically removed.
I found a flashable zip and script that will completely power off the cellular radio but it shows pie security check error in terminal -.-

Disabling VoLTE (Verizon)

Hello all!
Is there a way to turn off VoLTE? I use my phone as a hotspot, so when I get a call, I don't have internet access. I'm assuming this is because of VoLTE since my last phone (Droid 4) didn't have this issue.
Thanks!

I always thought having that option disabled is what caused data to turn off during phone calls. I have it enabled and I can still use data while on the phone. That's the toggle to the off VoLTE though.

Sounds like you aren't using VoLTE in the first place. Turning it off won't give you data during a call it would do the opposite.

Talk and web is only available if you have advanced calling option turned on within your verizon account. Its free.

It doesn't sound like you're using VoLTE exactly because you stated you can't use simultaneous voice and data. Here's the deal: To save battery power or whatever, the additional radio added to Verizon and Sprint (CDMA) phones to enable 4G has been removed from a lot of them, rather converged.
Verizon has always had this problem and they got around it by, finally, adding an additional radio to handle the 4G to many phones. On CDMA networks it's either (I think analog) voice or (I think digital) data. Then, I guess expecting this great big transition to VoLTE (and only needing one radio to simultaneously handle LTE and Voice over LTE) "they" reverted phones to the original model. I mean that has to be it... I would gladly charge my phone more to be able to be able to hotspot and talk! Or maybe they want to sell more JetPacks and separate line access fees!
(This is what allows for all that red on their coverage maps as Verizon's original voice frequencies do rock for signal strength and reliability. The data maps look a lot more similar amongst the carrriers: concentrated on major "markets" as the efficiencies of cities drive the capital to create the networks--rural areas have lousy 4G coverage).
The GSM networks from T-mobile and AT&T automatically fall back to 2, 2.5, 3 and 4G frequencies and can use the newer and the older networks at the same time. You also get better conference calling (up to 5 people) and call management on the GSM based networks.
If you want to use voice and data at the same time on Verizon, edit your account preferences to enable Advanced Calling 1.0 for your line. It is free. Also enable Enhanced 4G LTE mode as shown in the screenshot.
But VoLTE seems to bring its own issues: call complete rates will drop, call quality will drop, static bursts occur at the beginning of calls... it's a real mess.
I really miss T-Mobile, but their network isn't as good and I save money being on the family plan with others on Verizon.

Hi guys, I am having the opposite issue.
I can't get VoLTE ("HD Voice") to work. As a result, no internet when I'm on a phone call. A real pain in the butt.
I'm on CM13 on my Nexus 5x and using Verizon.
I had previously activated this feature on the Verizon website, and it shows the VoLTE flag is 'on' in the phone info/service settings menu. I've seen posts elsewhere where people say CM13 is not working properly with VoLTE.
Should I flash to a different ROM perhaps? Appreciate any ideas...
