I had a notification for this but doesn't appear in the status bar no more.

Might be writing but not sure.

3 UK

Personally I don't need it as I have unlimited calls.

Another severely unhelpful post on this thread. Go read the OG post (getting PDC to work) instead of commenting for the sake of commenting.

Actually I could say the same about you. Just ignore the message if you have nothing positive to say.

What exactly have you contributed? Besides moaning, information is important, period.

1. I stated my network (3)

2. I stated that i used to have a notification for this and wasn't sure if it was working or not, meaning something has changed in 11.

In no way it that unhelpful, it's stating facts, if you have the ability to troubleshoot; then information, specifically facts is the basis for all troubleshooting processes.

Drop the act buddy ok, it's not helping anyone, least of all yourself.

Back on topic and not measuring manhood.

In regards to the volte issue, I can confirm that my volte doesn't work any longer in my area, vowifi works fine and strangely when I'm in a different area volte appears to work depending on where I am, suggesting certain criteria isn't being met in my area any longer.

Tried this on the latest OO11 on Oneplus 8 Pro. Still the ports are not visible in PDC or EFS Explorer. The new SW is a piece of crap.

I was enable to activate VOLTE on 11.0.2.2. Lucky enough to manage PDC to recognise my device and selected DT denmark commercial profile and activated it.

Used this method.

If you're not rooted but willing to do anything to get VoLTE then root and follow this guide from the Open Port point or just follow the whole guide because it shows you how to root too.
I need to pay someone to do this to mine lol I just got mine gotta see about getting it going but I don't see where the drives download link is

It's funny, every time I see this *#800# option I never get the switches anywhere in the logkit that it pulls up. I do have VoLTE shown at the top though.

I call this the magic guide!
In the FTM mode, I got EFS explorer and PDC working fine. Be aware that EFS will take around 5 minutes retrieving data.

I can confirm that it is working for me (for the first time actually but it is due to the operator).
If others are on DU-UAE you can use the "Telefonica_UK_Commercial" profile.

I know there are a lot of guides. It's actually weird I never came across the ftm mode before.
I followed this guide up to using QPST. Before using QPST reboot the phone and enable the ports

Code:
# adb reboot ftm

once the phone reboots with chinses writing on it

Code:
# adb shell

# setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb

Now use first the PDC to select the Volte profile. I used the Telefonica-UK (with du-UAE)

Once that's done you can proceed and update the files from QPST (already on the guide above). I am not sure if it even helped but I actually don't have 5G (and I don't really care about it).

Reboot the phone and my volte popped up straight away.

You can call du on 155 and ask them to check if your sim card is provisioned with volte

Man I cannot believe the instructions were buried in a Turkish forum when on XDA and one plus forums people were going bonkers about it. Not sure if you are part of that forum but you can say big thank to the guy for the instructions (and lucky chrome has built in translation).

I think OP should probably update the first post with the link to the forum.

I am Turkish too, I have been looking for a solution for a long time (in xda and oneplus forums) I was looking at this site and when I saw that they found the solution, I wanted to subscribe here and share. Did I convey my thanks to the subject owner there. 😊

    I have managed to make volte and wifi calling working with Freedom Mobile (Canada) on Oxygen OS 11.0.2.2 OP8PRO (Android 11). Both sim cards are in use, lte switches from data sim to freedom sim during the volte call which is pretty cool.

    Hi, I'm going to give you a feedback on the volte and vowifi with Android 11.
    I have two French sim cards.
    Under Android 10 I was how everyone had to use the PDC software and load the correct country profile. At each update obliged to redo the manipulation.
    Since Android 11 and the first beta developers and open beta. No need to do this manipulation anymore.
    I made a data wipe from the recovery, to start again on a healthy basis and Android 11. Of course I did not have the volte etc ..
    I just downloaded the engineer mode apk and made the key combination * # 800 #
    To activate the volte and the vowifi.
    My OnePlus 8 pro is of course not recognized like everyone else by PDC under Android 11.
    But when restarting the wifi rt lte calls were available on my two sim cards. Without having loaded any PDC profile.
    Perhaps these operator options are native and integrated in Android 11 (at least for French operators).
    Currently I am under open beta 2 global.
