Data show an impressive increase in the use of and access to mobile technology, in both developed and developing countries. Mobile cellular is the most rapidly adopted technology in history and the most popular and widespread personal technology worldwide. Growing research demonstrates the potential of mobile communications to radically transform governments and to provide access to public information and services in areas where infrastructure required for Internet or wired phone service is not an option. M-Government is therefore emerging as the next big wave for information and communication technology (ICT) use in the public sector. For many public agencies, however, m-government is still in the early stages of development, and, in many instances, it is still part of an overall strategy of public sector modernisation and enhanced public service delivery. Understanding the underlying concepts and motivational factors which explain the emergence of m-government is crucial for governments to set priorities and formulate adequate policies.
