Resume the old \"pager\" to give to children instead of a mobile

 The idea is to resume the old pagers that appeared before the first mobiles to give them to our children instead of a conventional mobile.

We all know how dangerous a mobile can be for a child under 18 due to the contents they may see or the people who can contact them on the networks.

Well, a pager can be marketed that provides the location of the child to the father and mother  and that the father or mother can send messages through a sim card .

This would provide the same security to parents as the fact that their child had a smartphone to be able to contact him and in turn would minimize the risk that networks pose to a minor.
