Do students wear Apple Watch in class because of making phone calls or texting?

Pull up the dial-up interface and the interface will come out. The first interface has three modes, that is, it can call the interface of iphone. The third mode is silent mode. As long as you click, there will be no incoming call when the phone is turned off, but sometimes the sports software will remind you to stand up and move, and it will ring. It's best to keep silent at school.
