Sometimes the most frequent form of bullying can be nasty messages through social media, texts or emails. If you are receiving nasty or threatening texts or calls on your mobile, tell an adult like a parent or teacher. They can help you put a stop to this. If it doesn’t stop you need to tell the police. In the meantime: Don’t reply to any nasty messages you receive. Keep the messages that you have been sent so you can show someone. Don’t answer any calls that are from a withheld number, or from a number you don’t know. Change your mobile number and only give your new number out to close friends. If the problem is serious, tell the police or you can call us and we can help. Mobile phone operators can’t bar a particular number from contacting another phone, but you can’t do this on some handsets. Check your phone’s user guide to see if yours can. They can only take action about the bully’s account such as blocking it, if the police are involved. Find out more about being bullied through ChildLine
