Why we should use phones in school?

Do kids really NEED their phones in school? Well, there are many reasons supporting why they do need there phones, and many supporting why they don't. I'll list some reason why they should be able to have their phones. If you don't have a laptop or anything you can search up something if you don't need to know the answer. If an emergency happens you have your phone right there. Almost every kid has a phone these days and they act as if they'll die if they don't have one, phones are a sort of motivation. Of course there are many other reasons as to why they should be allowed to have phones, but those are some starters.
