Visual Tour: Kaspersky Mobile Security For Android Phones
Call & SMS Filter
The call and SMS filter offers an easy way to block unwanted calls and text messages. There are several modes but I found the most effective was to allow incoming calls and SMS messages from contacts in my address book. For unknown contacts, the app pops up a window that offers the choice to allow the text or call and add it to the list, or block it. It also offers the choice to block calls and SMS messages from non-numeric sources, a common tactic of spammers.
