Enable VoLTE and VoWifi on OnePlus 5

VoLTE (Voice over LTE) delivers voice calls over the internet. It is a digital packet voice service with many benefits for mobile operators and consumers.
Here are three main benefits for consumers:
- supports higher quality calls
- connects calls much faster (lower latency)
- improved battery life.

You can use VoLTE only if your phone and network support it.
My mobile network (Telekom Slovenija) supports it and VoLTE enabling is easy in the web dashboard:


The second part was enabling the VoLTE feature on the phone. Almost all modern phones support it, but some of them don't have this feature in the menu. My OnePlus 5 didn't show it (this depends on some reasons), but I knew that it is supported. Here is a simple tutorial on how to enable it.
The process is quite simple but be aware that something can still go wrong :-)

1. Open the dialer on your phone and type *#800#
This will start a special OnePlus app which is usually used when OnePlus service team try to help you with problems. Don't worry, press Enter to start the magic :-)
2. Click "oneplus Logkit":


3. Click "Function Switch":


3. Enable VoLTE (and VoWifi if you wish):

And then restart your phone. This is important!
After the phone comes to life, go to "Settings -> Wi-Fi & Internet -> SIM & Network" and there should be a new feature (or two of them if you enable VoWifi beside VoLTE):


That's it. I hope this short article will help you if your OnePlus doesn't have a VoLTE feature in the settings.

The VoLTE Switch option is not present in my one plus 5 when I open the function switch. How can I do it?

Iztok Grilc said...

It looks that VoLTE Switch option disapears with upgrade to Anndroid 10 on OnePlus 5.
But now you can find it in Settings -> SIM & network -> VoLTE (Use VoLTE when available).
Can you report if this helps?

Salekin Raz said...

Mine is updated to android 10.But the option is also unavailable in the settings

Iztok Grilc said...

Interesting. Maybe wait until OnePlus send us a patch for Android 10.

I don't find vowifi switch in OneplusLogKit after android 10 update. But I can see Volte option in settings. Can you please help me enable vowifi calling.

As I wrote in prevoius comment, I assume that something change with Android 10 update on OnePlus. Maybe we should wait some more days/weeks to get new version.

Doesn't works. There's no option to for VoLTE or VoWifi under function switch on my OnePlus 5. Maybe this is for a OnePlus 5T?

Iztok Grilc said...

This worked on OnePlus 5.

I've seen quite a fair number of people trying to enable this feature on their device but it's suspiciously missing after this most recent OS update. I'm personally looking to enable it so that I can prove AT&T wrong about my device not supporting HD Voice (their branding of VoLTE). AT&T recently sent out notice to users with "devices that don't support it," saying that we would be needing to upgrade our phones before Feb 2022 when they discontinue service for their 3G network. The OnePlus 5 is not that old of a device and it most certainly is capable of supporting VoLTE, but all of a sudden it seems like people are having issues accessing the settings. I can find plenty of resources on the internet (such as guides like this) that indicate it was at one point possible. I'm highly suspicious of the timing of the most recent OS update and this notice from AT&T about needing to upgrade. Am I being cynical or does it seemed like this might be a case of planned obsolescence to try and push people to the newer device versions?

Iztok Grilc said...

Maybe just a bug with a recent update?

I have a OnePlus 5, recently updated to Android 10. Got the same shocking AT&T Message Max S mentions. Its not that old! I never checked this before. But the timing Does seem suspicious. Thank you for the info!! I'll check back!
I hope OnePlus will fix this. If not, I'll not buy another OnePlus, it should last longer than this.
I really appreciate everyone sharing your knowledge! Thanks Max S.!
