Knee jerk reactions ignore the benefits. Your kids could carry small phones like this in their pencil cases for emergencies, for example.
After the recent car attack in Melbourne our prime minister was complaining that our tram lines allowed the driver to bypass traffic. But the tram lines are used by emergency vehicles. They facilitate fast responses to all sorts of incidents.
I’ve seen hospitals with a local cell tower to grab all the phones and only accept emergency calls. (Route those to the guard station.) That might depend on the construction of the building to work.
