Airplane mode + WiFi calling

Where I live there is -50 bars of cell service, so when WiFi calling drops it starts searching and absolutely murders my battery life. Is there anyway to hack the system to allow WiFi calling while in airplane mode? I've heard certain phones can do it. Are there any devs on here that have the know how? I know we have some very talented people in the community so I'm hopeful. It seems like it should be pretty easy because while on WiFi calling the cell radios get shut off and WiFi works in airplane mode, so?
I'm just not convinced WiFi calling will ever be more reliable and only getting 9-12 hours on a charge really sucks! Anyways, here's to hoping for a fix!

If you go to WiFi Calling Settings -> Conection Preferences -> WiFi Only.
I think that would do the trick.

^ Tried it out of curiosity because it would be useful to me, but that does not work.
I wonder if it would work if you used a program like Tasker to cut only the cell radios without explicitly entering "airplane mode". Although I'm not 100% sure that is possible or if some other work-around is needed.

Maybe there's something that can be added to the csc feature.xml? Not sure what it'd be but theres already these listed:
<CscFeature_Settings_Airplane_Wifi_Dependency>false</CscFeature_Settings_Airplane_Wifi_Dependency>
CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>false</CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>
You could check other devicrs that have wifi calling and see if theirs is listed. This may not even work, but could be worth a look.

Also, there's an app in the store called Bobsled Calling (also a Bobsled Messaging app) listed under T-Mobile top picks. Don't know how good it really is, but I was thinking bout giving it a shot on my old phone that has no cellular service at all.
One of the only ones I've seen where the people you call don't also have to have the app.
Maybe it'll allow you wifi calls under airplane mode?

You can try going to your Phone app and typing in *#*#4636#*#* -> Device information and then hit the 'Turn off radio' button. I used it before when Hurricane Sandy knocked out the cell towers and I was left with just random WiFi hotspots, but this was back on ICS. Though I don't see why it shouldn't work with JB.
If the code doesn't work, go to the Play Store and download an app called 'Phone info' (Author: [email protected]). The app should take you to the Testing menu.

Instead of constantly typing all those numbers (*#*#4636#*#*), download the app, Phone Info in the Play Store and there you go....

That app doesn't work because when WiFi calling is working the radio is idle. Service menu is a no go.
Sorry I didn't post it as a Q but I didn't have a clear question. I wanted to discuss the topic. I thought about yet where to post it before I did, thanks.

WiFi calling with Cellular Radio turned off
I am trying to accomplish the same thing but was approaching it from a different angle. The service menu idea doesn't work.
We are both trying to accomplish the same thing. Use WiFi calling while having the Cellular radio turned off. Airplane mode turns off all radios and you can re-enable the WiFi radio. However the Galaxy S III will not allow a call to be made while the phone is in airplane mode. This is a low level system issue and not related to the dialer (I tired three different dialers).
Does any body know of a way to do this??? PLEASE??? I'm leaving for Brazil in 4 days for a month and I would like to be able to do this in Brazil.

I am trying to enable WiFi calling with the cellular radio turned off.
According to Samsung & T-Mobile the only official way to turn of the cellular radio is to enable Airplane mode.
Here is the procedure that I tried:
Enable Airplane Mode
Turn on WiFi
Connect to a functioning WiFi hotspot
Enable WiFi Calling
Wait for the WiFi Calling Icon to appear in the status bar
Make a WiFi call
At this point the dialer sits at the dialing screen for more than 10 minutes (I bailed at 10 minutes). As soon as I abort the dialing attempt a dialog box pops up saying you cannot make a call while in Airplane mode.
Is there any way to completely disable the cellular radio without putting the phone in Airplane Mode?
Is there an app that will do this?
Is there a hidden that will do this?
Please don't use bandwidth by asking why I want to do this or suggesting that I use Skype or some other app. My goal is to be able to make and receive VOIP calls while the cellular radio is completely disabled.
Thank you for your help...

I think maybe the phone HAS to ping a cell tower in order to make WiFi calling work. For your purposes just set the WiFi calling connection preference to WiFi only.

I have zero reception at my house and wifi calling works.
Setting it to "WIFI only" doesn't allow it to work the way that's wanted - it just tells the phone to only make calls over WIFI - but that doesn't open up the ability to do so when the radios are off. From what is described I agree that this sounds like a conflict with the low-level integration.

Did anyone try that Bobsled app I mentioned earlier?
It claims that I could put it on a tablet or my old phone that has no sim/data, and it would work.
If it were to work is that something that could get you by for a while? I understand not wanting to go 3rd party, but it could be the only option for now. It is a tmobile app btw.

I meant for the guy going abroad. Although he needs to also make sure data roaming is off, I think.
Doc I did look but my problem is I want to use my tmo number. I have a house phone but it's really frustrating to tell people they have to try me at two different numbers. And not being able to text.

There's also a Bobsled messaging app. Pretty sure its the same deal and works via wifi.
Also, I could've sworn it said that you have the option of using your current cell number. Maybe I'm mixed up on it...
Anyway, its just a suggestion for looking at. I have no idea how good it really is... just don't have many other ideas for you guys at this point.
I wonder if there could be a build.prop value that would disable cellular only. Or set its scan frequency like you can do for wifi.

I have done some more research.
I was able to turn off just my cellular radio by using the phone info application to enter the service menu (Phone Info App->Device Information, scroll down and select Turn off radio).
With the cellular radio turned off I tried to enable Wifi Calling (Settings->More Settings->W-Fi Calling).
The phone says "enabling", turns on the cellular radio (without any messaging saying that it is doing this) and then says "Ready for Calls".
I also tried enabling WiFi Calling first and then turning off the cellular radio (using the method outlined above). But the cellular radio would not turn off as long as WiFi calling is enabled.
I don't know if this is a bug or a "feature" but for WiFi Calling to work on the T-Mobile SGH-T999 (4.0.4 Firmware) the cellular radio must be enabled. Though I'm sure T-Mobile has a reason for this the logic of it escapes me. WiFi calling should not need the cellular radio for any reason. I use Skype all the time and it doesn't need cellular service to operate on WiFi.
If anybody out there knows how I can make and receive phone calls using my regular cell phone number exclusively via WiFi (with the cellular radio disabled) please let me know. Many thanks to the person who figures this out

As long as you are connected to Wi-Fi, with Wi-Fi calling activated (blue icon showing), it should automatically disable the cellular radio. If you are connected to Wi-Fi, but no blue Wi-Fi calling icon, then it will turn on cell radio and start searching for towers.

Duh.. the reason to use it in airplane mode for me is that WiFi calling disconnects every few minutes and when the cell radio is searching since I have 0 coverage it absolutely kills my battery.

Sorry but you're not making any sense. You're complaining about your phone's search for cell towers killing your battery because your Wi-Fi calling keeps disconnecting? Let's say you find a way to disable your cell connection. Your Wi-Fi calling still keeps disconnecting and you still can't receive or place calls. What's the point? Longer lasting "iPod"? Maybe start looking for a way to fix your Wi-Fi calling problem would be a better solution, ie. Flashing a different ROM until you find something more stable. Duh!

These are the following options available (all of these options have the cellular radio enabled and working at all times):
1. Make calls using the cellular network only - WiFi Calling disabled.
2. Wi-Fi Preferred - Make calls using WiFi Calling if a valid WiFi network is available and connected. Cellular network calls are made when a WiFi network is not available.
2. WiFi Only - Makes only WiFi calls. Cellular calls are not made when a WiFi network is not available. Note: This does NOT disable the cellular radio.
3. Cellular Preferred - Makes cellular network calls are made if a cellular network is available. WiFi calls are made if a cellular network is not available and a WiFi network is available and connected.
When enabling WiFi Calling the cellular radio is briefly disabled and then re-enabled..

I've tried multiple ROMs and multiple routers so.....
My only "solution" would be to not use my phone at all at home and just turn it off. I'd rather have a longer lasting iPod than a paperweight.

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

I would start by looking over this thread if you are on T-mobile. https://forum.xda-developers.com/pixel-2-xl/help/t-mobile-wifi-calling-pixel-2-xl-setting-t3761477

I started that thread. I can't speak for other carriers but on T Mobile there is a setting under wifi advanced to prioritize wifi, called "wifi preferred". With that, if Wi-Fi calling is working, I get a Wi-Fi call most of the time when I'm near my home network.

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.

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.

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.
