Former US public HS Math teacher here. The summer before I started teaching I obtained a cell phone signal jammer (from the EU, where they're legally available) and quietly kept it in my desk.
I didn't have to confiscate a single phone over the three years before I walked away from the job. Lots of internal chuckles from me brought on by complaints about the signal quality in my room. Granted, this only worked because we had no student accessible WiFi.
I did worry about students being unable to reach out during an emergency, but cell phones were supposed to be left in their lockers during the day anyways and there was a landline in the classroom.
I wonder if any schools are thinking about legal jammers or even building new classrooms that are effectively large Faraday cages?
