In our secondary schools, cell phones are supposed to left in their locker until the final bell. A teacher is supposed to confiscate any cell phones they see in a child's possession during the school day and take it to the office for a parent to collect, and there are accelerating consequences. This also applies to other electronic devices such as MP3 players, elec. games, etc. There is NO reason that a parent has to text their child during school. If there is an emergency, call the office. . . I can't imagine an office not responding immediately, if it's a true emergency. We all managed without cell phones for years. When I confiscate a phone and the child is crying and begging me to give it back, my response is, "Believe it or not you will survive without it."
