[Q] Wifi Calling working but Off Under More Networks (Answered)

Hello,
I've found out that my wifi calling is being used even though I have it off in the settings of the phone. Although it's off I still can select the options under Connection Preferences: Wifi Perfered, Cellular Networkin Prefered and Never use Cell Network (not sure if that matters or not). I choose the 2nd option and noticed dropped calls around the outer edge of my wifi. But wifi calling is turned off. How do you permanently turn this feature off?
I do use wifi when I'm within my wifi area. But had no idea that wifi calling was still being used when set to off. Do I have to disable wifi all together?

Ok. I've found out that this is known issue doing more a search online. The only fix is to disable wifi altogether. There have been other suggestions but none of them fix it. I've heard that exchanging the sim chip that disables wifi calling might work but haven't heard anything consistent with that fix.
I'm just perplexed by this. This is a great phone yet whenever you enable wifi you enable wifi calling regardless if it's off. I just don't get how something like this would be considered a standard feature when other phones just don't do that by default. If I didn't stumble upon this information I would have never guessed that it was the main cause for my dropped calls.

Thanks about that update it could help others soon.

NP, I have to wonder if this is really a standard none controllable feature on the phone or if the carrier can disable it?. If wifi calling is controllable on the phone and you can turn it on or off jet remain on then I have to wonder what other external force is keeping it on when you turn it off?
Did the maker just simply forget to remove the ability to control wifi calling because turning it off simply doesn't work.
or
Is this something that the carrier did
or
Is this something with the sim chip
Another thing I've found that seems to be related to this. If you try to access your acct while Wifi is enabled it suppose to switch from wifi to 4G but it doesn't (and you can't access your account in tmo. while in wifi. Perhaps different software updates were used but it was seamless back then on a different phone.

This brings up another interesting observation. Once wifi is enabled you can't auto enable your 4g network when it's needed. IE: You can't review your acct for one. Is there a way to make sure that your phone has 4G LTE priority whenever wifi is enabled?

I don't know also how to prioritize the 4G LTE over wifi, good observation.

Update, I was able to use an old version of my account (which was used on an older phone) and was able to confirm that it is programed to disable wifi connection and activate the 4g services while using the my acct app without having to disable wifi manually. A message even popped up to tell you so. And once you exited the my acct app it would restore your wifi connection from 4g. So it is controlled via the program itself.
So it begs the question, why doesn't the newer version not do this? This now looks like 2 separate issues with wifi and wifi calling.

Verify if Wifi Calling is still enabled even though you have it disabled
I just found a way to verify if wifi calling is still enabled even though you have it disabled on the Note 3. Here is what you need to do.
1. Make sure that wifi calling is disabled
2. Make sure that wifi is already enabled and in use
3. Stand right next to your wifi router
4. Make a call
5. Listen to hear any wired sounding ringback (the sound you hear to let you know that a call is actually ringing the recipients phone).
6. If you do notice a wired sounding ringback complete the call and stay on the line for about 30 seconds or so.
7. Disable wifi while on the call.
8. Once disabled did your call drop?
This is what I did in order to verify if wifi calling is still enabled even though I have it disabled on my phone.
I'm not going to say it's happening to every one. Nor would I suggest it's a bad feature for those who need wifi calling. I just don't understand why I'm forced to use wifi calling when I fully capable of using my 4g network.

Can you check and tell if you still have signal (bars) when you are connected to WiFi? Or does it become blank (0 bars)?

That is weird. I tried your steps, I couldn't recreate the problem. Just to make sure, I was talking about the phone network signal, not Wifi signal.
If the bars were becoming 0, there is a fix. But otherwise, it may be a faulty unit. You can try and get it replaced.
BTW, try this and see if it helps: http://forum.xda-developers.com/showthread.php?t=2698329

Thanks man! Gonna try this

Rahulisola, thanks for the link. I was able to fix the issue by doing a factory reset. Not sure what caused it but now I can disable wifi and the call stays connected. Although I found it odd that wifi calling was forced enabled during the reset while I was setting up the wifi network. Disabling it after the factory reset setup did prove it was really off this time. I also noticed that I'm not seeing "HD Voice" which I know assume is related to wifi calling. As I've seen HD Voice whenever I was within my wifi range during a call.
Also, Lorettaa thanks for looking into this as well. I really don't know what caused the problem but I'm glad it's fixed now . No more of pitched ring backs while making a call. And no more odd echo voices when talking. And most importantly no dropped calls.

Glad that it is solved. Usually I always do factory reset 1st and ask anyone with problems to do that too. My bad, I assumed you had already done it. Must be some other thread. Too much work catching up on me
Anyways, enjoy your fixed Note 3

Wifi Calling?

Any way to activate the wifi calling feature for the Sprint S6?
rooted and xposed installed

I've tried on every build so far on my GS6 and haven't been able to get it to turn on, but it sounds like a few people have gotten it to work. I've spoken with Sprint multiple times about it and the only remaining test they want to try is to factory reset the phone...which is funny since the first day I also couldn't enable WiFi calling. They recommended I take it into a Sprint store so someone else can look at it, and probably factory reset it. I just don't want to spend the next 6 hours customizing everything on my phone again. I've also heard that the battery life isn't very good with WiFi calling (maybe incorrectly), so that's been another reason for me to not take the plunge and factory reset.
Sprint did mention, during all those phone calls and chats that WiFi Calling must be enabled on your account/line for it to work, which they say they enabled for me, but it still doesn't work. Maybe that's your hang-up....

Works for me on stock OH1. Took awhile for the red line to disappear from the icon but when it did I made and received several calls using wifi calling.

I am able to use wifi calling fine. I was just in Bosnia, Croatia, and Serbia where I used wifi calling constantly to call and text people in the US. I am on stock OH1. When you enable wifi calling go to the wifi calling options and make sure the wifi access point you are connected to us enabled in the wifi calling. To the point above, yes it does often take 30 seconds to a minute to enable wifi calling on any access point. If it starts to take longer I toggle wifi calling off then on again.

How do you tell the phone that a particular wifi network is able to use wifi calling? Whenever I try to enable wifi calling it sends me straight to "Self Service".

Wanam Xposed module (note module not framework) breaks the ability to access WIFI calling feature. I reported it here in module thread.

I might recommend doing an RTN reset...I know you said you don't want to set everything up all over again. But I had issues when I first got the device. This completely reprovisions everything and in my case fixed WiFi calling not even being an option. I would make sure it shows in your account and then do the RTN reset.

Wifi Calling Preferred?

Is there anyway to set the pixel xl to prefer wifi calling at home (I am on Verizon, but the google version of the pixel). Wifi calling works - would like to "prefer" wifi instead of cellular (I have amazing wifi and meh cellular at my home). Yes, I can airplane mode it every day - just seems like a very hacky solution.
-D

Not that I'm aware of.
I also have poor cell reception in my cave. (-110 on band 13). Pretty much every call I make switches to wifi about 3 seconds into the call connecting. It'll also come out of wifi calling if I walk outside where the cell coverage is good. (Even if wifi is still good).

I specifically called pixel support and asked them, no option for this currently. I wish. Need it as well
EDIT: I tried to bypass cellular altogether by turning my phone on airplane mode, then using just wifi to force wifi calling, only to get no calls going through. This is a bummer, I use my iPhone with wifi calling whenever I travel this way, to make sure I don't make any accidental non-wifi calls which aren't free when international. If there's a way to force wifi calls with wifi on and airplane modeon for cellular calls, that would also be useful for travel

It should work this way unless it is different than every other Verizon phone with wifi calling. Sometimes it takes ten minutes or so of failed calls before it finally connects, then you're good from then on. I'll give it a shot and see...

On T-Mobile WIFI calling there's a clear option for 'wifi prefered' or 'cellular prefered' which works pretty much about every single time. It's in the places, on the dialer and on network settings, but sets the same option. I guess with verizon it's different?

I put my phone in airplane mode for 20 minutes and it still won't do wifi calling after turning wifi on

Mine works fine. I put phone in airplane mode then turn on wifi and connect. Calls and SMS go through immediately thereafter.

Airplane mode works for me too. Just a hassle. I have had T-mobile before - so I know "wifi-preferred" is an option - is that a setting somewhere we can hack at? I can't imagine that is a hardcoded thing that is unchangeable...
Feels like something we could diff pretty easily.
-D

Not the best solution, but I wrote a tasker to put the phone in airplane mode then turn WiFi back on, made it into an app and put it on the home page, so I can press that to go into WiFi calling.

Yea weirdly still not working for me. Wifi calling works fine with airplane mode off. Am I doing something wrong?

Are you reconnecting to your wifi after enabling airplane mode? I know it sounds rudimentary, but idk what could be going on.

If you pull down notifications then swipe down again to expand quick options then select the mobile network icon then "more options" you can turn off cellular network. This will force wifi calling. Reverse when leaving

Update disabled WiFi calling in airplane mode

I'm on a rooted pixel 2 XL, on vzw... I just updated to the June security update (from April) and I noticed that it is next to Impossible now to get any calls to go connect as Wi-Fi calling (Even when I have terrible service)
I already have Wi-Fi preferred setting enabled but it's not helping.
I also noticed what I used to do when I was in the basement is put the phone in airplane mode and turn on Wi-Fi and I would get texts calls and be able to make calls under Wi-Fi calling. Now if I try to make a call it says it's not allowed in airplane mode.
Is there a way to get around this???
***EDITED TO ADD RESOLUTION***
A clean flash of the latest update (June at the time of writing) fixed this WiFi calling issue!

The airplane mode plus wifi trick still works fine for me on the June update, both for calls and SMS.
Wifi calling always seems to disable itself after a couple days or weeks and then I have to reenable it, but it's been that way forever.

I have an UNLOCKED Version and Wifi-Calling is set as the default way to place a call from the factory, and when not in Wifi, it doesnt use wifi calling, but then uses LTE... I am able to turn OFF Wifi-Calling, altogether, by going In settings -->Network & Internet--->Mobile Network-->Bottom of page shows Wifi Calling settings.

just to clarify, i do have an unlocked phone (also rooted), but im on VZW network (not a verizon model phone).
All of my settings are correct, it shows wifi calling as being enabled, it shows volte, advanced calling, ect all turned on...
but it NEVER uses WiFi to make a phone call anymore ( previously would show wifi icon in the dialer screen). i also used to be able to force it to use wifi calling by turning on airplane mode and enabling wifi, but now that is blocked very clearly by a dialog warning.

Once you turn on airplane mode the wifi turns off too. You need to turn on wifi after you go airplane mode. It should work.

Did you dirty flash the security updates? Not sure if its Magisk 16.4 beta causing a problem? I doubt it because I was running that before the update. Maybe that was it...

I dirty flashed the June factory image using deuces script and I am using Magisk 16.4 beta. It maybe time to clean wipe; that usually solves any problems with this phone.

Shot in the dark here... I was having the same issue and even called Google (Project Fi) about the issue. I accidentally discovered on my own that I had to dial the area code when on Wifi or it would give me the error "Turn off airplane mode to make a call". This was when dialing only 7 digits. When I dial with the area code the call goes through over wifi with no problem. Maybe try dialing with the area code or with 1+area code+number.

Since it obviously works flawlessly on stock June update don't you think it's time to try that in order to eliminate hardware as the problem? Otherwise you're just spinning your wheels and asking to figure out a unique scenario.

OnePlus 7T on Google Fi

Has anyone activated a OP 7T on Google Fi recently? If so, does it work well and does WiFI calling work?

I have activated my OnePlus 7T on Google Fi and have been using it for about 2 or 3 months now. I'm not sure about the WiFi calling, I don't see an option for it in the Google Fi app, and I don't see an option for it in System Settings anywhere. I can tell you that you can't install Google's Phone app. I don't know why, it shows up in my Play Store Library, but I don't have the option to install it. Service is still good. Sometimes calls do take time to actually start dialing and there are a few locations in my area between cities where my service will drop but the radius that I lose service in is rather small. I didn't have the service dropping issues with my Pixel on Google Fi.

I switch back and forth between my Pixel 4 XL and My OnePlus 7T, and I also use Googe Fi. If you're rooted, you can download the google framework magisk module. I then downloaded the google phone app from apkmirror, and set it as default phone app. I also have the WiFi Calling option in the Google Fi settings. WiFi calling is funny like that with Google Fi though. for me, the only time that I actually know that I'm on a WiFi call is when I see the WiFi icon on the connected call screen of the phone app. Hope this helps.

Yep, not google fi here, but using the google phone app. Install the google dialer framework magisk module. Then you should be able to get google phone from the play store. Make sure you go to google phone's app info and allow "display over other apps" or else the chat bubble (whatever it's actually called) won't work. I have it set as the phone app, and the oneplus one disabled.
The oneplus dialer is better suited for dual sim calling though :\

So I've got a OnePlus 7T and wifi calling had been great for several months. I just noticed today that it wasn't working, and the option is suddenly gone from my Fi app options. Has anyone else experienced this?
That said, if you need wifi calling I may hold off on switching until someone else can verify that there's is ok.

I am using it. Activated few days ago on tmo version (HD1907). Prior to that it was converted to international fw 10.0.16.HD65AA.
Everything seems to work except:
1) I have option to enable Wi-Fi calling in Google FI app, it is enabled. If I turn phone into the plane mode and enable Wi-Fi it doesn't allow me to call saying I have to disable airplane mode. This used to work on Pixel. So I cannot tell it VoWiFi works or not, maybe yes maybe not, you will never tell unless check your billing and/or be in an area where you only have Wi-Fi and maybe roaming. I wasn't.
2) I am unable to switch network to Sprint, even though it shall be formally merged with TMO by now. Signal Spy just cannot do it. That said, it used to do it on Pixel couple years ago, but stopped working even on Pixel. So I am uncertain if that is a body or merger issue. Yet have to be in an area where only Sprint or US Cellular towers are present, but this will hardly happen.
3) FI specific google VPN does not work (this is for a good in my book).
Visual voicemail works with OOS phone app.
I can install google dealer without Magisk module, so that module is not needed on this FW. I don't see any benefits to use it though, except if I would like to use Google's call screening and spam protection. I am using a 3rd party dealer anyway with its own features like that pre-existed Google's implementation. I.e. if that is an issue, that issue can be solved by a 3rd party SW, you are not bound to Google here. But you can install their dealer on global FW if you so want.
Other than that everything seems to work. I'd like to see what happens in roaming but I don't expect problems there. It would be a very strange idea to prohibit roaming based on the IMEI. Anyhow, there is no way to check during the times of closed borders.
I didn't install a second SIM yet though.

Update: today I was in the area without network but with Wi-Fi. Wi-Fi calling with FI works. I was able to make and receive calls via phone app. App was showing it is calling via Wi-Fi. So that is purely artificial SW limitation that I cannot make calls from Airplane mode with Wi-Fi enabled, when in such situation it works.

I've been using my 7t on Google Fi for about a year now. I am using stock software and stock apps for voice. I installed google messenger to resolve some chat issues (from play store). Wifi calling works as it should with stock dialer as well as mms/sms.
The only issue I have had is... the phone will not automatically switch to the strongest provider. In my area, the strongest provider is t-mobile, therefor I essentially have a t-mobile data plan through Google Fi.
Typically I find that wifi calling increases the time from when you finished dialing to the instance of the phone actually ringing. Without wifi calling, the timing is spot on.
zero complaints.
