When you put the phone into Silent mode, or when you set the phone to block calls and
notifications using Quiet Time, Game Acceleration, or Anti-harassment, you can add certain
contacts to VIP Contacts, which will allow them to override the phone settings and have their calls
come through and ring.
Add contacts to VIP Contacts. Go to Contacts, select a contact, and then click Add to VIP Contacts.
