Hello All,

Has anyone been able to get VOLTE to work on OP 8 pro after Android 11 update ?

There was a method through QPC on Android 10. However it looks like since updating the Qualcomm device doesn’t show up anymore.

The option is still present on engineering mode & in settings but the VOLTE icon doesn’t show up & making a call results in network reverting to 3G (H+) .

Funny enough this update (11) got the 5G to work but disabled this option above.

I am on IN2025 North american varient on 1 sim in sim 1 , not rooted either but willing to try anything to get VOLTE to work.

Any insight would be appreciated !

Hello everyone, I am facing exactly the same probelm. Searching other threads including oneplus forums... there is a dead silence regarding this.
Seems folks dont know how to switch the phone to full port mode or serial mode to get qualcom tools to work and upload volte profile on the phone.

Hope this will be known soon. Otherwise really happy with Android 11, second SIM started to work.

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.

Hello Zayatoshi,

So you just wiped the phone after 11 update then it just shows as working ?

I am able to use engineer mode apk with *#801# combination the option is showing in settings but VOLTE is still not working making a call it goes to 3G (H+).



I am in Canada on IN2025

Hi. with me the wipe data was not linked to the activation of the volte and other. but with each change of version of Android and prefers to redo a clean installation. the * # 801 # key combination is useless because it is used to switch to full port Switch and then connect to PDC. friends seen under Android 11 the op8pro is not recognized it is useless. the wipe may be tested. but did you activate the volte and vowifi with * # 800 #, and restart your phone? These options must be active with the operators. And with Oos there is the volte logo which is present when this option is activated. I just activated these options and since the volte is present even after each update. without pdc uses

Ok guys by some miracle I got it to work!!!!

Here's what I did.

Install stable Android 11 full version.

Use *#800# to activate VOLTE then restart.

I then switch my sim card from OnePlus 8 Pro to my old galaxy S9 where VOLTE was working before then make 1 call to ensure volte is working on S9.

Then switch sim back to OnePlus 8 Pro & boom VOLTE is working on Android 11 !! .

I have followed this method and it did not change anything for me.

Provider - Freedom.
I have another phone Pixel 3a, pulled SIM from OP , put it to Pixel, ensured volte / wifi calling works there , switched SIM back to OP , no result.

Looking for another solution. I don't believe reset of the phone will make any difference.

Thanks all.

Did you make a call on Volte on the other phone ?
Make sure it stays on LTE for that call to confirm its working (on other phone) then put the sim in the OnePlus.


Also, did you enable volte on OnePlus using engineering mode ?

I'm having the exact same issue.
Tried to replace sims on a different phone and verify that the SIM does support VoLTE - didn't solved the issue.
Looking forward for a decent solution.

    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 have provided the pdc connection with what is explained in the link below and activated the volte. My device Oneplus 8 Pro in2023 android version 11.0.2.2.IN11AA (non-root)

    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.
