How to Enable Wi-Fi Calling

    Patrick10 , Oct 23, 2016 :
    Just turning off the cellular data does not eliminate cellular network. It only stops the phone from using data while still being connected to the cellular network. To simulate bad/no reception you have to turn on airplane mode, and then turn on WiFi. If WiFi calling is working, then you should be able to make calls even when there is no cellular connection (this was the purpose of creating WiFi calling in the first place). That is how other phones with WiFi calling works.

    So, in short, even though we are able to turn on the WiFi calling switch, true WiFi calling does not work on OnePlus One.

    Wi-fi calling is very simple on OPO.

    1) Get married.
    2) Handover your OPO to your wife.
    3) Now ask your wife to call.

    It's just so simple.

    I get terrible T-Mobile reception at my work and on 13.1.2-ZNH2KAS3P0, following the steps in the original post, this does not work. I get the "emergency calls only" message (all radios enabled and the Wi-Fi Calling preference is set to wifi). I also rebooted the device after enabling WiFi calling to make sure everything was fresh.

    Three have now enabled WiFi calling (and ditched their horrendous intouch app). Does it work for you now?

    Do you have to use Nova settings to enable WFC?

    This does not work. I have talked to T-Mobile to set up a 911 address and replaced my (old) SIM card on the recommendation of their tech.

    With cellular data off, I can place calls as long as there is a cell phone signal. When the cell phone signal disappears, I get the same message as others.

    With airplane mode on and wi-fi on, I get the same message as others.

    I honestly don't see the point of wifi calling....most everyone has unlimited minutes these days anyway right? Just use your cell service....unless you have wifi but no signal, like in the basement of a library or business

    Was a solution ever found for this problem?
    Just activated this phone. I've downloaded a lot of apps over wifi already. I have done all of the steps to activate VoWiFi through T-mobile. On my phone I went into engineering mode and used the and used the OnePlus Log Kit to turn on the VoWiFi switch. Rebooted. Went into settings and selected Use WiFi When Available, and WiFi Prefered.
    When I try to make a call in airplane mode I get "Prompt To place a call, first turn off Airplane mode. OK". When I turn off airplane mode I get "Mobile network is not available. Connect to a wireless network to make a call. OK"
    This is while I AM connected to a wireless network. What am I missing?
