text: If a student gets sick or needs something having a cell phone with them can let them call home to contact someone. Even though they can call from the office having a cell phone on hand is a quicker and easier way to contact somebody. Also if a student has some kind of after school practice and can't have their phone with them at school then they won't be able to let their parent know if practice is running late or will finish early. Cell phones are necessary for students to have.
