Call Forwarding problem : Note 20 Ultra

[AsadFarooq]

I am unable to find call forwarding settings. Internet tells me to go to call settings and then supplementary services. There are no supplement services in my device. Please help if you can. Thanks

It should be there. See snaps from this site also :

If you don't find those options in Phone App settings, then search for USSD Codes for your respective network.
You can set and delete call settings using USSD Codes aslo. Go for that option.
