Phones can be used for multiple things. Most schools don’t allow students to use them. Responsible students should be allowed to have phones in school.

According to kwikboost, “If a student forgot his homework or calculator on the day of a calculus test, he could call his parents and ask them to bring it to school without causing a scene. In more serious emergencies, cell phones could help students contact worried parents.” Phones can be used for important reasons.

Most people have a RemindMe app. Since kids use their phones a lot, it can help them remember to do things that they will seldom forget. If they are allowed to take their phones out, they can put in the assignments that they need to work on at home.
Phones can also be used for education purposes like using calculators for math homework and looking things up. According to DebateWise, “Students can take notes when they forget their notebook or pencil.” The teachers could let them use them for fun educational games too. When a test comes, the teacher can just have the students put the phones in a box upfront.
