İt may be working without showing it. Back in pie, my phone didn't show volte symbol but had volte working properly. Easy way to check is; make a call on 4g, if it drops to 3g or 2g, it's not working, if it stays on 4g, then it's working.

Hi tusharguin29
Because you mentioned that the issue appeared after update to Android 9 V087 in your region (North East?) and you had performed the Factory Reset, can you help me to check:
1. Does the issue remain in Android 10beta? Please backup the data and perform manual update with OTA file WW-17.2017.2012.438. Download the file into the root directory, aka the outermost place, of the internal storage.>Reboot>Tap the system update notification.

2. Does the issue remain in WW-16.2017.1912.060 or WW-16.2017.2007.084, previous version of V087?
Downgrade the device by Version MaxProM1_downgrade_to_9 file with SDcard.

Hi tusharguin29
As other users reported above that they didn't have the same issue with VI card, please provide me your current testing result in Android 10 beta and Android 9 V60 and V84 for further checking. Thank you.
