Limit who can call your cellphone. (IPhone)

You might be able to do this in Android but I’m not familiar with how. On your Iphone go to settings, focus, choose the focus you are currently set to. tap people, enable allow notifications from. Then select “allow calls from” and select “favorites”. To make this work you need to go into your phones contact list and add them to your “favorites “ . Also you keep your phone on the focus you configured.. (if you have trouble adding contacts to your favorites let me know but it’s pretty simple)
