Hi hayyam 
Thank you for your reply. Have you ever rooted or unlocked your device before? I am asking it because your "SIM page" looks different from mine yet we are in the same firmware version. May you provide me a video of the SIM page for further checking?

I never rooted or unlocked my device before?
Is it posssible to understand whether it is rooted?
Here is video for you 🤗

Hi hayyam 
Sorry it's my fault. The access of the page I showed above is Settings>Connections>Mobile Network>Advanced.

Yes I am in ADVANCED page....Then? 🤔
WIFI CALLING is OFF now..

Hi hayyam
Thank you for your asking. You may check on the screenshot I provided, normally the VoLTE toggle exits between *Data usage and *Preferred network type.
1. May I know why you want to access the toggle? Can you use the VoLTE now?
2. What is your sim carrier?
3. If you change another sim carrier card, does the VoLTE toggle appear?
4. If you change *Preferred network type, does the VoLTE toggle appear?
