“Many schools have become dead zones for data connections because they don’t want kids playing on their phones.”
You are full of conspiracies!
Have you tried getting online at a school lately? In our district, visitors can only log on through a district website. If you try to use cell data, it does not work. Also, many websites are blocked from the district website log on. So, call it a conspiracy if you wish, but it hinders First Responders in their communications.
