How do I do that?
I understand not wanting to receive calls from private numbers, themacguru. We do offer FamilyBase which is normally used as a feature for usage controls, but it does have the option to block unknown and private numbers. http://vz.to/1hLDJODAndreaS_VZWFollow us on Twitter @VZWSupport
Look at apps like You Mail or Google Voicemail for blocking restricted, unavailable, or blocked incoming phone numbers for free. Family Base will do the same but there is a monthly fee.
