Hello Airtel Support,

My SIM has WiFi Calling enabled in phone settings, VoLTE/LTE is working, WiFi internet is stable, but IMS is not registering over WiFi and the VoWiFi status bar icon does not appear.

Please refresh/reprovision the following on my number:
- VoWiFi / WiFi Calling provisioning
- IMS registration profile
- VoLTE provisioning
- SIM network profile refresh
- ePDG / IWLAN access for my device model

Please confirm that WiFi Calling is active for my SIM and device IMEI.
