Hi @hasnil_nc, welcome to the community.

VoLTE is supported on the handset but relies on the firmware provided by your network. Your network provider will need to supply you with a firmware update to use VoLTE.

Try restarting the phone. I am using Jio SIM and I have VoLTE enabled. Also if possible set network to LTE only.

After recent 7.1.1 update volte and wifi calling was nowhere to be found so i typed *#*#4636#*#* and found those options are turned off.. so if i toggle them on ,can i be able to use them without any software issues later on?

There is no problem with 7.1.1 related to VoLTE as I am able to use it.

First restart your phone and then check after dialing *#*#4636#*#* (Engineering mode)>phone Information> VoLTE Provision Flag is enabled and network is set to LTE only.

Also go to mobile networks from phonew settings menu and check that Enable VoLTE option is marked.

Hi,

I know firmware updates are controlled by carrier/network

but still i don't understand VOLTE feature is enabled via an update than a couple months later an other update is come and it was disabled the VOLTE

There is still volte supported modem config in current firmware but of course default configuration is loaded beacause oem settings are not complete

I know you say "contact your local vendor or your carrier/network we can't help you" but

they had no idea what i said

I really dont't care VOLTE but that's not way to fix problems I just wanted to remind you
