What precautions should parents take with children's mobile phones?
Keep children careful, give a small phone
The phone has a merit: in trouble you can reach family, police or an ambulance. It can also corrupt the mind when one is alone, so keep children careful and give a small phone.
The merit is that if you are in a serious problem, you can inform anyone. You can contact the police and call an ambulance.
