VoLTE is not working on the latest security update of June month. Please fix it Nokia as soon as possible.
Yah, i'm using jio and facing the same issue, i'm not able to make and receive calls on my jio number after june patch update.
Even VoLTE in my device is not working after june update. Earlier it was working on both the sim. Now its not at all working.
So here is what I gathered. With the new update patch, the VOLTE works for Vodafone but is broken for JIO. HMD - we are all looking at you to make life normal for us, again...
Yes, it is really surprising that there is no reply from Nokia, when many people are suffering from the basic calling feature . This is very bad from Nokia, Regretting for buying Nokia 7 plus. They lost my trust finally. Never refer a nokia mobile to anyone. Hmd Global also made Nokia Dead.
I think, Nokia is not listening to us.
However friends you can use Jio sim in your Nokia phone through Jio 4g voice calling app.
