First of all, apologies for asking such basic questions.

I have done something similar to this procedure on a 5 and a 6 previously, but now I am the proud owner of a 9 pro europe variant and would like to enable VOLTE as per your instructions.
where do I find th apk's listed on your instructions list?
What version of PDC is needed, I have one installed from 1 year ago is it the same one?

Thank you so much!
I am still not able to complete the full procedure though.
After step 11, the shell accepts the command but when I load pdc the phone does not show up in pdc.
I used the pdv version in the attachment. Any ideas on why this is happening?

Reinstalling Qualcomm drivers did the trick with PDC recognizing the phone.
I tried to use two different profiles that used to work on my 5 with VODAFONE PORTUGAL, and as such i tried with India-volte-vodafone and with telefonica_uk_Commercial.
None of them gave me working VOLTE with Vodafone Portugal.
For both of them I activated sub0 and then sub1 and confirmed that the status on PDC shows as active, then rebooted but phone is not showing VOLTE enabled. And under the SIM settings the VOLTE switch is enabled.

Any ideas? Maybe a different profile?

Try using Vodafone UK volte profile and close the pdc application after activation before restarting

I did everything according to this guide and finally got VoLTE. Thank you.
For me 5G is not working, but I have 4G+ all the time, even during phone calls
