Mobile phones are one of the most common ways that children and teens are cyber bullied. Cyber bullies may send or forward mean text or photo messages or make harassing phone calls. While it is difficult to trace a cyber bully knowing only the mobile phone number, you can contact your mobile phone operator, as well as the bully’s, and they may be able to help identify the bully. Also, you can monitor your child’s cell phone usage and persuade them to not respond to the bully, but keep a log of harassing calls or messages. Using the log as evidence, you can contact the bully’s parents, as well as your child’s school, and get the bullying to stop.
