Well, your idea is true but I have to disagree with that because smart phone for kids currently is very useful. If in case of the kids have to travel alone. Go to school alone If an accident it will help the kids call for help quickly and also can call connect to parent or relatives and friends far away. When they get lost their ways, they can always contact someone they know to lead them the way because if they ask strangers, they might not get the right answers comparing to asking the people who are sure of how to get to that exact place. It doesn’t waste the time,right?
