This article explores the social meaning of locale in mobile communication research and introduces an approach of user localization to study technology integration. It investigates how locale forms an essential role in mobile communication in the way that practice, agency, and identities are articulated into a user localization process of incorporating technology into user's everyday life. It argues that the use of mobile communication technology is both a complex and dynamic interaction with its surrounding social, cultural, technological, and economic conditions, and an articulation work of self and locale.

Current localization practices suffer from a narrow and static vision of culture resulting in usability problems for IT product and design. To address this problem, this article compares user localization efforts of mobile messaging technology in two different cultural contexts with a new methodology of cultural usability. It calls for expanding the scope of localization practices and linking user localization efforts to the IT product design cycle.
