I think it is not good a thing because many students how have phones they just be with it day and night when ever they are free and they wont be interested in physical involvement games which are good to them. many students how have phones they be back of it only day and night. so I request don't use phones or give them to students.

Advange of mobile phones is dat v can contact for urgent needs...if any doubts in studues can contact wit friends......can listen songs for relax or some thing lik dat..... But if v think on the negative side, experts worry that mobile phones cause varying levels of addiction and interfere with personal relationships. lower concentration among children who are distracted by their phones when studying. Studies show that mobile phones can cause anxiety and depression, especially in teens.
