Mobile technologies are deployed into diverse social, cultural, political and geographic settings, and incorporated into diverse forms of personal and collective mobility. We present an ethnography of transnational Thai retirees and their uses of mobile technology, highlighting forms of mobility that are spatially, temporally, and infrastructurally anchored, and concepts of the house as a kinship network that may be globally distributed. We conclude in pointing out several ways in which our observations and analysis can influence design.
