Masks allow you to add similar numbers to the lists of blocking and allowing filters.

•Numbers beginning with a certain sequence of digits (or other characters)

•Numbers ending with a certain sequence of digits (or other characters)

•Numbers containing a certain sequence of digits (or other characters)

To add a mask

1.On a screen with the necessary list, tap the icon and select  New contact.

2.If necessary, edit a name.

3.When typing a number, use a star * at the beginning, end, or both.

A star replaces any sequence of characters. Do not use a star in the middle of a number or two stars in a row: such mask will not work.

4.If you add a mask to the blocking filter list, select what to block: Calls or SMS.
