There should be VoLTE option for your sim..
If no, There is many chances that your SIM maybe not 4G ready or your circle don't have VoLTE feature..

Needs root but the only way I got it to work here is with the magisk module.

Ya, don't go playing with the band selection, or you may just get dropped to 2g connection with no LTE possible.
After digging around, I found a fix to get LTE back.
Download the "Network Signal Guru" app from the Play Store.
I told it to "Clear Forcings" in the menu, and LTE is back up.

Cantn find The Module can You give some more Informationen?

This won't work in Europe at least, no matter how Volte ready is your network/SIM card. OnePlus just ignores the issue.

This method https://forum.xda-developers.com/on...-volte-vowifi-german-carriers-t3817542/page28 works for activating VoLTE if your operator had enabled it for you.
I tried the method in the current post, but only got the toggles in the menu and not the real thing.
Had to call the mobile operator (Telenor BG, Bulgaria) to ask them to activate VoLTE and then did the method in the linked post.
I have a non-rooted OP6 and I'm now effectively using VoLTE on my network. Hope that helps.

Hmmm, does anybody know which was the previous default setting? I would like to revert it back and don't remember what setting was set before...

It doesn't work with Kuwait Viva !

If you want to get VoLTE and VoWiFi menu under SIM options in your OP6 just type *#800# in default dialer (not working in ther dialers) and under oneplus logkit>Function switch there is VoLTE and VoWiFi switch This is only to have that switch visible in menu so it isnt a guarantee that VoLTE will work on your device because your network carrier must support it and if it is not supported by carrier then VoLTE will not work no matter if you enable it with menu switch

Follow my Guide to activate VoLTE and VoWiFi for OnePlus 6...

Thanks, I used your guide and was able to enable VoLTE for my Vodafone.de LTE contract, my second card is from Sparhandy which is also I believe Vodafone but without LTE/4G, unfortunately VoWIFI is not showing up, I confirmed with Vodafone/LTE contract that it is enabled and it is, any suggestions?
TIA

somebody knows how to set up VoLTE on OOS9 ?
"Enhanced networking" missing for me

No one in Pie tried to set up VoLTE

VoLTE and VoWiFi just work, what setting up needs done?

Go to "Phone", Settings, SIM & Network Settings, then in to the SIM you want, and the VoLTE and WiFi calling is in there. It's NOT in the traditional Settings app.

jamal2367's method (see here in English: https://forum.xda-developers.com/oneplus-5t/how-to/guide-volte-vowifi-german-carriers-t3817542) works fine with OOS9/Pie.
Just updated & patched modem config with PDC as described in the link (I'm using the config "Telefonica_UK_Commercial" for O2 in Germany) and I'm up again with VoLTE/VoWifi working..
Still a shame that Oneplus is incapable to do enable the right config by default..

but it is just that in OOS9 you miss those switches what were in OOS5.11 in "Enhanced networking, this group is all missing in Pie

VOLTE Three UK

Has anyone got this working, the icon is enabled but it's not showing up.

Volte only works iff you buy a volte compatible phone from 3 shop. It has to be one of there phones or its blocked. Unlike on O2 iff the phone is volte compatible it even works with some of there pay as you go phones. For this reason i am going to leave 3 after my contract finishes.

My last phone was a phone not sold in the UK but that worked?

Which phone was it and where did you buy it I know for a fact that any phone which has volte but not bought through 3 store will have the volte IMS service blocked because you need there version of Android firmware for it to work. I have had many arguments with 3 customer support over this.

the Volte and Wifi Settings are blocked by OP in their official firmware because they need the carrier to allow the settings on their phones. Some Asian imported phone manufacturers sometimes disobey them and allow it but this is not the norm.
Have you noticed that when you put in a sim from a major operator in the uk the internet/mms etc settings are usually auto configured?
three for example, configure their sims to block any 'non authorised' phone to auto download the required settings to enable wifi calling and volte.
This means that the only way of bypassing it (a bit like Sammy csc changing) is if there is a custom ROM available with the three settings pre loaded. EE are the only network that are essentially a 'slut' and allow their settings to (on the most part) be uploaded to any compatible phone.
I get 100 gig a month, unltd calls and text from Three for a ridiculously low £15 per month. I WILL NOT give that up !!!!
as much as i want an OP6 im sticking with a tried and tested Samsung S9 plus that to be frank is just as fast on the most part, and you can easily load three or whatever branded software to enable all the wifi calling and volte goodies.

O2 allow this also. The only real way to get volte working on a non 3 handset is when 3 release there factory stock images eventually and they can be flashed after rooting. Even with custom roms volte will not work for instance lineage etc although volte is implemented still doesnt work. I had bought a lenovo p2 a few years ago and volte did not work for a whole year untill 3 factory images were released and i rooted the phone and installed the 3 firmware then it started working. 3 are real scumbags in this regard.

all u need to get three volte working is essentially the ims settings, ive seen people being able to get three volte and wifi calling working on various grey imports. But agreed its a very convoluted process.
All one plus's use their own firmware, they dont have carrier versions like samsung and others ...

That is correct the only way oneplus would have volte settings is iff 3 sold oneplus on contract otherwise it is a difficult process. I would be very interested nevertheless iff someone in the future figured out a way to get volte working on a non 3 phone other than using there firmware. By the way i am not a oneplus owner but in fact i have a xiaomi mi6 but i am in the same boat ref volte.

Unfortunately, I was able to flash the H3G firmware onto my Italian source S8 and use both VoLTE and VoWiFi without ever speaking to Three, same applied to the unbranded S9 I got from CPW SIM free!

I have access to a OP5T and VoLTE and VoWiFi both worked out of the box!
My Pixel 2 - not a chance!

It's easy my dude, there are some bugs with it but hey you can't have both of the best world just yet.
Tutorial : Open Magisk - > Go to Downloads - > Search for VoEnabler - > Reboot - > Activate the VoWiFi and VoLTE in the settings. - > SUCCESS.
Bugs? Only bug I found is that every time someone calls you it will say Unknown (While on VoWiFi, haven't checked on VoLTE yet.)
Let me know how you get on

Three VoLTE working here too using Vo Enabler.

Sorry i am in the weird situation although im not a oneplus 6 owner. I have a xiaomi Mi6 and i used the module voenabler and now i can make calls over wifi but the enhanced Lte option in settings has vanished completely and in the 4636 settings the option for wifi calling became available but the volte option is now greyed out.

I have got VOWIFI working on 3 with pie, I upgraded to 9.0.0 then did this
Dialled *#800#
Went into OnePlus logkit
Went into Function Switch and checked VOWIFI and VOLTE then rebooted
The options now appear in SIM settings and you can turn them on or off.
When I installed 9.0.1 the Function switch options had been removed but as I had already turned them on the SIM options persisted On installing 9.0.2 the Function Switch settings had returned but with a dev test warning.
I have entered airplane mode, turned on WiFi then made and received a call.
The 3 IMS was automatically configured

And some screenshots

I was able to active vowifi but volte is not registering, I did notice that when I connect to WiFi a do a call and during the call I disconnect the WiFi volte start working but only on that call after the call finish it discomect and goes back to no volte. This is on three UK with Pie using the logkit.
@crazdgrunt99 does volte still works for you using the vo enabler?

Got Volte working with 3UK
I got Volte working in my OP6 with 3UK. I used the softwares mentioned here - https://forum.xda-developers.com/oneplus-5t/how-to/guide-volte-vowifi-german-carriers-t3817542
I only installed the softwares mentioned and used *#800# oneplus logkit to enable volte/vowifi options- after that I followed other method used by Jamal , guy who figured out these methods for OP6 (please take EFS backup before this procedure)
Open EFS explorer that is part of qpst software, select your phone , it will start loading directory and files-
Once the directory structure is loaded , go to following path - nv/item_files/modem/mmode
Open the attachment with this post. Delete all files that are same name as in the attachment from Mmode directory in EFS explorer. Note some files are not there. After deletion load the files from attachment to EFS explorer - load as item files - you can select all and load
Reboot phone and it should have Volte working.

Now that A10 is available for the OP6, I can confirm VoLTE working on both OB1 and the production version, at last. (no hacks required)

What about WiFi calling that works too

[Guide]Enabling VoLTE on stock ROM (Calls and SMS)

Hi all.
I just want to post a guide for people wondering how to enable VoLTE in unsupported countries. Apparently, Xiaomi only enable VoLTE for SEA countries etc. and Japan (Where I'm staying) is not supported.
So, I have been having problems receiving SMS and calling other numbers. After reading this blog post, I have solved that problem and maybe I can help others solving this problem. This is the procedure written in the blog post in English.
1. Setting APN (Might not be applicable for other countries)
-----------------
for Au user with VoLTE enabled sim, create a new APN and set it as below
・NAME:ims
・APN:ims
・MCC:440
・MNC:51
・TYPE:ims
for DoCoMo user with VoLTE enabled sim, create a new APN and set it as below
・NAME:ims
・APN:ims
・TYPE:ims
・APN protocol:IPv4v6
2. Go to dial and dial *#*#86583#*#* . It should show carrier check disabled or something along the lines.
3. If the phone does not have a signal after step 2. reboot the device and it should connect after that.
Hope this will help anyone who is having trouble enabling VoLTE.

thanks man . *#*#86583#*#* did worked for me in Sri lanka

I'm glad I was able to help

its a pity there's not such a short code to enable the VoWifi in the same way
EDIT:
Turns out setprop persist.dbg.wfc_avail_ovr 1 enables the switch, but the service still shows as unavailable.
using the build.prop changes I came up with for this https://forum.xda-developers.com/oneplus-5/themes/magisk-volte-enabler-t3649647
enables UT interface.

Volte Restore
Run the below code in your dialer app manually. You should see a message stating "Volte Carrier check disable" else run the code again.
After 30 seconds your volte network should be retored. Pull down the notification bar to check for the volte symbol.
*#*#86583#*#*
Cheers!!

Hi
Thanks for this topic.
I have a problem : my poco F1 (MIUI Global 10.3.5.0) says it is enabled only for SIM1.
But as I use a µSD card (which has to be plugged instead of SIM1) I only have SIM2 place to put my SIM.
So I only have SIM2, no SIM1, and my poco says "only for SIM1"...... WTF ?!!
Someone has an idea for having VoLTE (and VoWiFi) on SIM2 ???
Thanks !

Activating VOLTE on unlock V600TM(Tmobile)without rooting or installing whatever

I activated my VOLTE for my unlock TMObile phone V600TM running on the latest android 12 version 30f by just the below commands
enter dial, type *#546368#*600#
Field test
IMS setting
Test
PreferenceOperator put OPEN
Preference country put MY (according to your country example Indonesia would be IND or America with be the US and so on)
Tick the 2 options below
✓ Support Volte on Command
✓ Volte setting enabled
restart ims process
Once done go to the mobile network option and add the below APN(not sure if this APN is universal but it works for me in Malaysia in all the carriers so I guess you can give it a try) don't delete the existing APN
APN: ims
APN name: ims
APN type: ims
after that restart your phone and you will see the VOLTE sign appearing next to the wifi symbol and so on. Make sure your 4G signal is strong enough if not it won't appear.
Also, I notice when I use the 4636 commands to check it still says IMS is not registered and Volte is not provision but I can use Volte maybe this is the bypass as I tested the call and so on already just make sure your Sim card supports or is Volte activated as well.
Also the Volte setting wont appear in Mobile network but it will work with the VOLTE icon appearing

My TMObile V600TM phone is network locked.
How to unlock it? if yes could you please point me out?
thanks

Lg phones g8x, g8, v60, velvet Volte enable for all carriers, unlisted countries also
I will try to keep this post as small as possible. This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files. Many have posted ways to get it, Iam only trying to help out the small bits missing...
forum.xda-developers.com
thanks to the OP for this thread, really pushing for these amazing devices to live on, you can follow my first steps to get the IMS option to open up.

Tried it on V600TM30C in Greece (GR) Cosmote and worked! Thank you! I have tried other ways (rooting,etc) but none worked so far.
I have also tried it on V600EA10 but I couldn't enter IMS settings menu and the johndaniel tutorial didn't seem to work, so I restored my back up to V600TM30C. I still need to find a way to have 5G.

anyone tried Lg v60 L-51a ???
