Speaking is Golden
Children and teenagers are by nature curious, eager to play and want to test everything especially with the use of mobile phones. They very frequently know and use the technical opportunities offered by a mobile phone more intensively and with greater skill than adults. It is particularly important that you have regular detailed talks with your children on the usage as well as the dangers arising from using mobile phones. Critical content such as, "grooming" (harassment through third parties), "bullying" (bullying via mobile phone) and "happy slapping" (shooting and distribution of violence) amongst others have appeared and turned into noticeable phenomena. Children and teenagers are generally not conscious of the rapid and vast networks used for communicating through mobile phones and are accordingly unable to recognize the consequences this can have for the persons affected.
An option is to have your child explain its mobile phone to you. This will not only enhance the child's self-confidence but will also show you how adept the junior is in handling mobile devices and where possible lacks of information can be. It is best to always be open to any questions or problems your child may have so that if some issue arises he or she will turn to you rather than friends at school.
