Students should be able to use their phones for two reasons. The first being to be able to communicate with others better. If students were given their phones, they would be more aware of their surroundings and better able to adapt to new things. The second reason students would benefit from phone use is in case of emergencies. If there is any type of accident or emergency, students should be able to use their phones to contact authorities, parents, and friends.
Best of luck.
