Ban the use of mobile phones in primary and secondary schools

As a parent of two children progressing through secondary education, and a further child in primary, I have witnessed first-hand the grave social and mental health issues directly associated with the use of mobile phones in and around the school environment by students. From the proliferation and enablement of bullying through social media access to the social-divide exacerbated by device brand and model. Remarkably, some students are now actively encouraged to use these devices in school.
