Mr. Number is definitely the most comprehensive call blocking app with regular auto blocking features.

For example, numbers starting with “0800” or number from specific areas using the area code. Furthermore, it has a huge list of known spam and telemarketer number that will let you know of the threat before you pick up the call. You can also block these spam numbers without being bothered by them.
