Block Spam Calls
Incoming calls for which Spam rules applied are completely blocked, and the call does not occur. No one, from advertising agents to strangers, can bother you if they are on your spam list.

Block Unwanted Calls
When you receive the call from a number for which the Unwanted rule applied, it marks as ‘unwanted’ on the screen. So, you can choose: to answer or not.
