Seeking Help How to block all international calls

[iDJ]

Got charged ₹9 for 9 second of call as some id*ot from Saudi Arabia decided to leave a missed call. Unfortunately, this is not the first time this has happened. Does anyone know steps to block all international calls to avoid being charged.

If you use true caller, then go to settings, block- then block number from foreign countries and it's done. But that will need true caller to be default caller app. The other way is to not to call them back at all, Any number which have prefix other than +91.
