I don't know. And maybe you're right - but I'd bet it's the attempt by the school the quell all kinds of complaints from parents like "what if my kid gets suddenly lost on the way home? what then????" by giving them a phone that has some mapping capability, it's just crap - but I guess it will do in an emergency.
Because this is an advertising puff piece for the light phone. I’m going to guarantee you that someone in that company has connections to that school.
