How to Enable Wi-Fi Calling Aug 25, 2016

narceoneplus2, Aug 25, 2016 :

I recently updated my OnePlus One to the newest incremental Cyanogen OS update (COS 13.1.2-ZNH2KAS3P0). While going through the settings, I figured out how to enable wi-fi calling. I have tested it several times to make sure that it works and it DOES!!! Below are the steps of how to enable it.

Note: Enabling this setting was done through the Nova Launcher app, which I currently use. Also, this was only tested through my T-Mobile SIM.

1. Long-press on an empty space on your home screen and select Widgets.
2. Select Activities and drop it onto your home screen.
3. When the Activities menu appears, scroll down until you see Settings and tap it to reveal more options.
4. Scroll down until you see Enhanced radio control and long-press it to make the menu appear. If you tap on it, it will just create the widget on your home screen and you will have to start back from step 1 to do the rest.
5. In the Enhanced radio control menu, tap on the option that says TURN ON WFC DEBUG. It should now say TURN OFF WFC DEBUG. WFC stands for wi-fi calling, in case you are wondering.
6. Press the back button to return to the Activities menu.
7. Scroll down some more until you now see the Wi-Fi calling option and long-press it to make the menu appear.
8. Once you are there, turn on the switch found right below the search icon, which looks like a magnifying glass.
9. An option called Calling preference will now appear. You have two options to choose from below:

• Wi-Fi preferred: All calls are made over an available Wi-Fi network. If there are no available Wi-Fi networks, then calls are made over the cellular network.
• Cellular preferred: All calls are made over the cellular network. If the cellular network is not available, then calls are made over an available Wi-Fi network.

Pick whichever you want.
10. Exit the Activities menu and simply reboot your device. You will now have the ability to make Wi-Fi calls. Thanks, Cyanogen.
