"This guide provides an overview of relevant and innovative examples of how mobile telephones have been successfully integrated into development projects and processes; and a three stage process to help Plan staff and other development practitioners identify the key social, economic and technical factors and issues they need to consider when planning to use mobile technologies. The information provided and analysed here is derived from a literature review and interviews with people in the field. A list references is provided at the end of this guide. It is hoped that this blend of examples, learnings and reflections will support Plan’s staff and partners to make well-informed decisions about integrating mobile technologies into their work."
