Find Out Who's Calling
If you receive a text message or a call and don't recognize the number, you can use ordinary search engines or specialized phone number directories to attempt to find out who texted you. If you are receiving unwanted contact from a phone number, you can block it on your phone or contact your phone company for help. Keep in mind that caller ID can be faked. If you're receiving threats or harassing messages, consider asking the police for help.
