How to enable VoWiFi on OnePlus smartphones!

@Ameen I have op7 on android 10 and i don't have the option. So i guess it is not necessary

It has been disabled by default by OnePlus. You can enable the option using the below given steps:
1. Dial *#800#
2. Go to Oneplus logkit
3. Go to function switch
4. Check on Vowifi switch
5. Reboot your phone
6. go to settings -- wifi & internet -- sim & network
7. Turn on WIFI Calling
8. Reboot your phone

Wait few minutes you will see volte will be replaced by vo-wifi .

VoWiFi on OnePlus is not stable atleast on my 5T. Sometimes, it comes and goes though occassionally. Could be because it is not officially supported by Jio.

@thadougamer Same on op7.

About 12 hours into the very first time VoWiFi started working on my OP5, well, it's still working without a hitch except that, unlike my iPhone, it does NOT work when the handset is in airplane mode. I do not know if this is by design or by accident as formal support for the OP range is not been announced by Jio.

I don't know who over here told me.. That there won't be any difference...
I got my op6t vowifi finally after updating it to Android 10. Did all the test with android 9 I couldn't get it working.
Btw @varkey I got the airtel vowifi but still no Jio VoWifi.

Yup, I enabled on my OP5T on 14th Jan 2019. I was just messing around to see if worked. Telecom provider Airtel.

Updated my 6T to 10.3.1 with the December Security Patch, but still no VoWiFi on Jio.

I think its Jio's fault not OnePlus. I have 5T and I have VoWiFi on Airtel.
