Mobile device are arguably another revolutionary invention of our time, besides computer and internet technologies. Mobile technology is growing by leaps and bounds. From 1990 to 2014, worldwide mobile phone subscriptions grew from 12.4 million to over 6.9 billion, penetrating about 97% of the global population with Asia as the fastest growing region and India being the biggest market of cellular phones (after China with 893.3 million users, TRAI (Telecom Regulatory Authority of India, 2014) cited in Chun, (2012) . Mobile phones today go beyond just voice communication and provide a multitude of other features and services including short message service (SMS) or text messaging, multimedia messaging (MMS), photo display and recording, video playback and recording, calendaring, reminder (clock and alarm), web-browsing, checking e-mails, retrieving sports scores and news, using online dictionary etc. In other terms, mobile device has become an essential part of everyday modern life. However, to many, the mobile phone is not a tool for making just phone calls, but rather, a ‘lifeline’ to the social network and an instrument for smoothly operating and coordinating their everyday life (Ezemenaka, 2013).
