Sick of getting spam messages on your phone? The Filter is a useful application that gives you a chance to stop receiving spam SMS that annoys you every day – unique/beautiful design and easy operation to meet all your needs. The application already has a list of blocking keywords for each country. You can manage your block list by adding/deleting your own new keywords like TAXI, PIZZA, SALES, etc. A message that contains any of spam words will be moved to a special “Junk” folder in your Messages app. When you receive an SMS or MMS message from an unknown sender, the Messages app asks Filter to determine whether the message is unsolicited or otherwise unwanted.
