Got Verizon and want WiFi Preferred for WiFi calling? I just found the way!

[abuttino]

Looking through "settings list global", I noticed something that could be pertaining to WifiCalling.

wfc_ims_mode=1

I changed it with Tasker and AutoTools to 2 and then enabled and disabled airplane mode and it stuck!

I don't even believe you need root to change this setting.


---- NOTE ----
If you have never activated AutoTools Secure Settings, read this:
https://joaoapps.com/AutoApps/Help/...utotools.activity.ActivityConfigsettings.html

You might as well just skip to the adb section on this post (below) instead.
---------

A1: AutoTools Secure Settings [ Configuration:Setting Type: Global
Name: wfc_ims_mode
Input Type: Int
Value: 2
Read Setting: true Timeout (Seconds):60 ]

For those who don't know Tasker and AutoTools... Create a new task. Choose Plugins, then AutoTools, then secure settings.

Choose custom settings
Choose Setting type
Choose global
Ok

Choose Name
Fill in wfc_ims_mode
Ok

Choose input type
Int

Choose value
Fill in the number 2
Ok

Press the back button then the check mark on the top and the back button one more time

Press the play icon on the bottom left and wait for the small green circle on the left in the AutoTools line

Go to settings click more in the wireless area and see that it is now WiFi Preferred.

----- ADB INSTRUCTIONS -----
Enable ADB Debugging Mode in Developer options

Plug your phone in.

On your desktop, go to the command prompt and change directory into where you keep ADB.exe

If you have never connected your phone to adb, you'll have to allow it. Type adb shell and you'll notice a pop-up on your phone screen that asks for permission. Click yes and try the adb shell command again.

Then type this

settings put global wfc_ims_mode 2
Press enter.

For pros:
adb shell settings put global wfc_ims_mode 2

Look at your wireless settings (more menu) and you'll see that WiFi Preferred is active

-----------

Don't forget to toggle airplane mode and, it should be set to go. It persisted through a reboot, it will be interesting to see what else it persists through.

Thanks for looking into this. I will have to try it on my stock XL. Bugs the heck out of me that its cellular preferred. I am in an area where VZ signal is terrible so there is a 5 second delay when I answer the phone for it to kick over to WiFi calling.

Confirmed working. I did this with terminal emulator and am now showing WiFi preferred and WiFi calling is actually on and working.

 

[iceman4357]

I must be doing it wrong. Opened up ADB Minimal, check to make sure my devices was connected. Tried typing in exactly what you said and I get "settings" is not recognized as an internal or external command.

I should be able to skip the Autotools and go direct to ADB correct?

@iceman4357

adb shell settings put global wfc_ims_mode 2

It will not read anything back to you for the command being completed. Just check your WiFi calling settings

Yes you can skip AutoTools config and go right for the adb method

Awesome find! This worked for me too.

With Auto Tools, is there a way to disable mobile data when WiFi is connected and enable mobile data when WiFi disconnects?

If you have root or AutoInput

Root, Just use Tasker and the secure settings plugin disable mobile data

AutoInput and Tasker, find the System action for mobile data, then toggle it off.

If you need the xml to import, please PM me with your email address

I did it with the adb method. And it survived a power cycle. I assume it's good till a factory reset.

Nice find~. I did it by accessing the secret menu with *#*#4634#*#* via a one click app. Then I just turned off cellular radio power to and Wifi call worked just fine and was preferred by default. Downside is having to shut mobile data off each time. So thanks for the share!

Tried the ADB method on a Verizon Pixel XL with a Project Fi SIM, and it does not seem to have made a difference in my menu options.

If your using Windows, make sure your in the correct folder.

 

[abuttino]

You can do the same with putting it in airplane mode but that's just not conducive to people that have to remember to take it out every time they leave home or work

Well. That's most likely because Fi defaults to WiFi calling anyway.

Besides, this method I discovered was only tested on a Verizon Wireless SIM

Thanks for the info though

Fi defaults to cellular like Verizon, and I want it to prefer WiFi, which is why I tried your method and reported back.

I wonder why this hack didn't work. Very odd.

Are you sure you did it right?

I'm pretty confident I did, but I've tried it again and screenshot everything this time. Any thoughts? I'm on stock 7.1.2 with June patch.

 

[abuttino]

Is this the Pixel? It's tons different than my menus.

Try adb settings list global and you should see the prefix wfc_

Give me that screenshot

Yep, Verizon-sold Pixel XL with Project Fi SIM.

FWIW, I tried changing wfc_ims_enabled to 1 as I noted it was 0 and that freaked the phone out.

 

[iceman4357]

Update-- Only down side to doing this, at least for me on Verizon, is:
1.) Visual Voicemail does not work. I have to turn WiFi off for it to actually play the messages. It will show the message on WiFi, but will not play for whatever reason.
2.) I now have to dial an area code regardless of it being in my same area code. If not it will give me a Verizon Error recording.
