OnePlus Wifi Calling + VoLTE

4: Newbie

Ok - so I contacted Vodafone yesterday evening and asked them to activate Wifi + Volte, which they said they did.

All the relevant options are enabled, in the hidden menu, the Sim setting and Vodafone account.,..

Have rebooted the phone this morning - but still no wifi calling, still says 'turn of flight mode' when I try to make a call in Airplaine mode + Wifi...

 

Ah well - never mind...

Do you have the VoWIFI symbol at the top? 

Just tested it and it now works in aeroplane mode.

Trying to think what else might need changing. 

Could try this, what I did after I spoke with Voda. 

Settings > WI-FI & Internet > SIM & Network > SIM 1 > Enhanced Communications > VoLTE and WI-FI Calling ....unselect and select again.

Thanks  - tried unselect and reselect - still not helping.

Also tried changing 'Calling Preference' under the Wifi Calling - but not helping.

 

Did you get any SMS messages from Vodafone after you spoke to them and they enabled the features on the account? I think the guy might  have said something about confirmation message - but I cant be sure...

 

Thanks.

No, got nothing through from Voda. I just rebooted my phone ten minutes later and there it was.

I have very generously given my wife my old OnePlus 3T and moved her from O2 to Vodafone SIM Only (12 month contract). Does anyone know if the OnePlus 3T can register to VoWifi on Vodafone? Perhaps worthy of note my OnePlus 6T required a settings "hack" and I have completed the equivalent settings change (via *#800#) on the 3T. Thanks

Thanks for the update @harry66, one of the team will be in touch  as soon as we reach your message.

If the phone you've given your wife is on our Wi-Fi calling compatible phone list @danouk, you'll be able to get this added by calling 191 from the phone.

Hi @Mark,

One of your support guys responded - but only to tell me that WiFi calling is not supported by Vodafone on the OnePlus 6 - so no real help to be honest.

Vodafone were always going to say that, they don't officially support it. 

 

Are you on a normal fairly new monthly plan?

Thanks - thats what I figured - so not sure why Mark asked me to contact them?

Long term Vodafone Pay Monthly customer - current contract is around 8 months old..

 

Like I said - it would have been nice if it worked - but not a biggy.

UPDATE:

Ok, so as mentioned preivously, when I tried Airplane mode + WiFi on, I could NOT make a WiFi call - phone would ask me to disable flight mode.

 

However, a few days ago I was in an office block with poor Vodafone signal - but connected to the corporate WiFi.

When I received a phone call I thought I saw something about Wifi Calling popup on screen ...

And then I saw it again today in a different office block!

So, anyway, I tried the Airplane mode + WiFi enabled test and sure enough I was able to make a call!!

 

So - it appears that sometime between the 3rd of Jan and last week, the WiFi calling started working??

And before someone asks, I have not yet installed the latest OxygenOS 903 update...

Re airplane mode, why do you want to make and rexrece calls with airplane mode switched on? I enable airplane mode when I want my phone to be completely offlline and not disturbed. I also use it to preserve battery. What's the advantage of wifi calling in airplane mode Vs not in airplane mode?

 

By the way I got WiFi and VoLTE working on my Oneplus 3T this requires 'root' for the settings to persist after a reboot. Screenshot below shows the carrier settings within the OnePlus 3T firmware, open market options work with VodafonePDC.png
