Alright guys. I did it. VoWifi activated in Airplane Mode on my OnePlus 7

Calls and SMS incoming and outgoing working on both the numbers.



Original Guide is here. But I have simplified the process below because that guide is as confusing as it gets.
  1. Download this zip as it contains LogKit and EngineeringMode apk. Install them both on your OnePlus phone.
  2. Dial *#800# -> oneplus Logkit -> Function Switch -> enable VoLTE switch & VoWifi switch & VT switch and then reboot your phone
  3. Go to Settings -> Wifi & Internet -> Sim & network -> Sim 1 -> enable VoLTE and Wi-Fi Calling switches. Do the same for Sim 2
  4. Use the Drivers and software from below and not from the above link as the drivers mentioned in the original post do not work.
  5. Correct QPST drivers here.
  6. Correct QPST software here.
  7. Install both the QPST software and drivers with default selections during setup.
  8. Connect your phone to USB port of your PC and dial *#801#
  9. Only enable Full-port switch
  10. Open "PDC" in your QPST start menu folder, best to do by right click & "run as administrator"
  11. In the drop down menu, chose your Qualcomm device. For me it was Qualcomm HS-USB WWAN Adapter 9091 yours can be different.
  12. In the list, Right click on Germany-VoLTE-Vodafone -> SetSelectedConfig -> Sub0
  13. Again Right click on Germany-VoLTE-Vodafone -> SetSelectedConfig -> Sub1
  14. Now just select Germany-VoLTE-Vodafone and click on Activate button at the bottom.
  15. Reboot your phone.
  16. Profit?
TBH it's extremely easy

Can someone report their findings?

@sanke3 #6 link doesn't seem to be the QPST software & QPST from #1 doesn't have Germany-Votle**

Please check.

@Notorious check now
BTW you can also use India-VoLTE-Vodafone or Telefonica_UK_Commercial profiles. Both work same.
Vowifi on Jio is a bit flakey. Sometimes it activates on Airplane mode sometimes it doesn't. Maybe OnePlus Oxygen OS bug,
Safe to try this hack on 7t? @sanke3
I think so considering you can revert to stock settings quite easily or just perform OTA update which resets things to default.

Sub1 isn't needed if you don't use Sim 2?

Lovely hack (y) works on Hathway and Jiofi on Airplane mode

@sanke3 Would this also help to force enable VoWiFi on Jio? I do have the WiFi Calling toggle switch in settings, but VoWiFi doesn't work at the moment.

@varkey
It will force enable VoWifi on Jio but Jio should have enabled it for your state from their backend first.

@mr_grump5 Sub1 is Sim 2 and Sub0 is Sim 1. But no harm in enabling it for both slots at the same time.

Yeah, it works for my friend on his iPhone, same circle. It's just doesn't work on my 6T. 😑😑

Btw any chance to do this from a Mac? I don't have access to a Windows PC 😔. I'll try with a VM.
