OnePlus 7 Pro VoLTE and VoWiFi

VoLTE (Voice over long term evolution) and VoWifi (Voice over Wifi) are standard wireless communication that allow your phone to access higher bandwidth network for high-quality calls. They ensure crisp voice quality and enhanced signal for better communication because they continue using 4G network instead of switching to 3G/2G during calls. These technologies are also very smart. Carriers have ensured that these settings can distinguish between a voice call and internet data usage so you’re phone bills will be significantly reduced as well.

Devices have to be certified to enjoy by network operators to access VoLTE and VoWifi as an option. Which is probably why the Samsung and Huawei counterparts are using this technology where OnePlus 7 Pro users are stuck using 3G data and the device’s Wifi. Unfortunately, OnePlus phones, in general, don’t come with this technology from the box. This support is not enabled by carriers in this phone despite the fact that these phones are available with many of them.

  1. Hi , thank you for the article . I have followed your instructions on my oneplus 7 pro (using on Bell in Canada). And it still switched back to from 4G+ to H+ when making a call. Am I doing something wrong? I’ve checked all setting and Votle is checked. I’m usually a Samsung guy and votle worked correctly on samsung with Bell. please hlep thanks

  2. Great article. I’m with Vodafone UK who have VoLTE and VoWiFi but not available on my OnePlus 7 Pro. After installing your different OnePlus Log Kit, the options turned up. Flipped the two switches and it works perfectly!

    Thank-you so much from the UK, Andy

  3. Hello, works great with OnePlus 7 Pro and for UPC Switzerland (VoLTE and VoWiFi).
    Thank you very much.

  4. 7 + pro. There is no f****** option for it. I hate OnePlus. What a waste of $800. No f****** Wi-Fi calling despite my provider supporting it I can’t turn it on with the phone. The secret menus don’t work either for it. Cheap Chinese s*** is probably loaded with hidden spyware anyways

  5. I tried this on a 7 pro on Verizon and the option to turn on Wi-Fi calling appeared but every time I turned it on, it turned itself back off as soon as I left that screen. Any other suggestions on a work around?

  6. OnePlus 7 Pro on Verizon, Running latest Beta of Android 10. It gave me access to the menu (in settings, wifi and network, sim) but it won’t stay enabled (it isn’t greyed out, it just switches back off when I leave that menu)

  7. It is working and all the settings are succesfully updated, but still call routing through mobile career.. 🙁
    Though calling preference i have set as wifi..

    Career supports Wifi.
