In US (And other regions) , there is separate stock app called "Visual Voice Mail". That is not being provided to India by Samsung.

Here , you have to get a separate VoiceMail number from your SIM provider. (That is a chargeable service)

Once you have a VoiceMail number, you can set it up in :

Phone App > Settings > VoiceMail
(If you have 2 SIMs , you get options for both SIM)

Samsung and no Android phones have built in on device voice mail feature like iPhone. If u want to activate voice mail then you can do so on Airtel number(free of cost) but not on Jio number. Also, this service is carrier dependent.
