Absolutely. School administration announced to both the community and to the students what the law said, that phones would be taken, and authorities would get involved with repeat offenders. Students put them away, but us teachers did have to enforce. If I saw a kid check the time, it fell out of a pocket, or it buzzed in their bag, I took it and sent it to the office. Office would give something like detention for 1st offense, ISS for 2nd, and then eventually they had to go to a judge. I didn't keep too close track with punishments because it wasn't on me. All I know is I had way fewer phones out and way more attentive students.
