For many people now, mobile phone is essential to their life. Young adults who are enrolled in professional or other graduation studies in India, apart from using cell phones for call functions and sending and receiving SMS, often use them to play games, surf the internet, and send/receive emails. They also prefer playing with features on the cell phone (including reading online news and downloading songs, wallpaper, and ring tones) appears to have become the adolescent leisure phenomenon in recent years. As the phones have become cheaper and more sophisticated, sales of cell phones to teenagers have become more common. However, as the cell phones become more compact, concerns about problem use are growing. To date, there has been almost no study of whether cell phone use is addictive or dependence-forming among medical undergraduates, a major professional stream in India.
