Antispam is a free application for rejecting junk SMS and MMS.
It watches for incoming messages and quietly moves junk ones to it's own inbox. The application uses simple but efficient logic, so it will disturb you very seldom. You can review rejected messages at any time and return messages that you need back to inbox. Antispam will remember your choice and won't reject such messages in the future.
I believe, Antispam will make your life a bit better.
