I would to know how can I block the incoming call from unknown number?
I have an IPhone X.
I have registered “unknown number” and “no caller id” as contact and block them but today I received no caller id call.
Did you know if Swisscom have an option in customer center for blocking all call from unknown number?
thanks for your help.

And try to activate the Swisscom Callfilter from your Cockpit.
