Samsung M30 comes with VoWiFi a very useful feature for Indoor voice calls. This can be enabled by enabling at Settings->Connection->WiFi calling. I have tested it with Airtel and i know from friend that it works with Reliance Jio. It seamlessly hands off call between VoLTE and VoWiFi. So if you step out of your home then you will get connected to VoLTE. VoWiFi is indicated by a phone receiver symbol along with WiFi symbol on the top of your phone. It works with SIM 1 and SIM2.
After enabling there are few bugs which are there:
1. If one use bluetooth, the VoWiFi does not work (My VoWiFi provider is Airtel. Not sure whose problem is it). So switch off the bluetooth to enable VoWiFi.
2. It sometimes hang esp if use medium/maximum power saving or adaptive power saving. If you have used any of this and you do not see VoWiFi symbol you will need to restart the phone to get VoWiFi.
Enjoy VoWiFi and always buy a phone with VoWiFi going forward. This will ensure you have lesser call drop problem.
