A grade-2 student said, “I couldn’t concentrate during classes if the cell phone was with me. I couldn’t help checking if there were messages or missed phone calls. I even played games on the phone sometimes.”

The school authorities say they feel the ban is necessary to keep order in class. They even gave out an open letter to remind parents not to let their children bring mobile phones to school.
