Yes 5g is supported very well on jio. But it is not having vonr facility right now. If you are using 5g for data very good, but if you get calls or you make calls then the network keeps on shifting from 5g to volte. If u see the pictures in the attachment you will notice that next to 5g it is showing volte. I am desperately waiting for VONR only on next update of samsung f23. Hopefully we get. If your developer mode is on and you search you will notice our system shows vonr sim1 and vonr sim2 when u tap anyone off them it will take you to the developer option but do nothing over there it looks like samsung has hidden it for now maybe in the next update we might get it. Hopefully
It's working
