As you have said mobile phone is a instrument of studies....
Mobile phone should be allowed to school. .
As you have said mobile phone is a instrument of studies. . . But why it will be used inside schools. . There teachers are already there to teach us. . . So why is it necessary to carry a additional device which might disturb us. . . If anyone want to use phone for studies he or she can use the device in home to assess learning. . . But why to use such Device in school where we can get a live assistance that's our teacher. . . . In schools students might start browsing irrelevant, Inappropriate websites and waste their time which can be utilised for studies. Also, They will be negatively influenced by the content of badly chosen sites which will hamper their overall growth, Mindset, And personality.
