To make sure you don't miss calls from your family and friends, phone numbers in your contacts are always allowed.
Block numbers directly from your phone's missed calls screen. Just follow these steps:
1. Tap the “ i ” button next to the missed call. 2. Tap “Share Contact”. 3. Tap “Block Similar Numbers”. (If you don't see this action, tap “Edit Actions...“ to enable it.) 4. Now you'll see the Number Shield number entry screen. Tap “Done” to block calls from similar numbers.

• Each number pattern can contain up to 7 wildcards, and up to 50,000,000 phone numbers can be blocked. • Blocked calls are sent directly to voice mail. • Blocked text messages are sent to the “Junk” filter in the Messages app. • iMessage messages are not blocked. • When “Do Not Disturb” is enabled on your phone, calls that should be blocked may appear in your phone's list of missed calls.
