Then I guess this is only available on Vodafone.

EVS 24Kbps on Jio. But usually they use 13.2Kbps which less phones support

Samsung has announced that it is bringing the Voice Focus feature to more mid-range Galaxy A series smartphones via Voice Focus.

Is it because of this?

(Some are wifi calls and others are VOLTE HD Calls)

I have Motorola Edge 30 Ultra and VI Sim in Mumbai. I talked to a colleague and he has Rjio and OP Nord. Even when the call is connected to him, suddenly it shows 4g+

Does it show 4G+ on the network bar?
If yes then it's carrier aggregation.
