I can't deny that handphone is really useful for everyone even the students. Students allowed to bring their handphones to school can have mixed feelings.
As we know, some students are rather boastful. They will tend to show off their smart phones and belittle those with cheap ones. I suppose the best way for them is to keep their handphones securely inside their school bags in silent mode. They can check on their phones when they are having their recess time and on dismissal.
To ensure proper usage, school will have to play a very important part. That is to make sure that all goes well and the phones are being used for the right purpose.
