You can download the mobile phone security manager, which has blacklists and whitelists. You can put his number on the blacklist, so that he won't bother you when he calls you or sends you a text message. The system will prompt him "The number you dialed is busy" and so on. The short message he sent to you will not be sent directly to your email, but directly to your security manager software, and he will be displayed on the mobile phone desktop in the form of a small icon!
