Mobile phones emerge as a new vehicle for resistance against employers’ control and social isolation, as well as maintaining distant relationships and local social networks. Through a survey and interviews with 68 female foreign domestic workers (FDWs) in Singapore, this study further investigates FDWs’ mobile phone usage for professional and personal communication with employers, family overseas and local friends. The findings show that FDWs have distinctive patterns for professional and personal use, including topics, time, and length of communication. They tend to use mobile phones more for connecting with family and friends than communicating with employers. Text messaging is the most popular function while voice calls are used only for emergencies or special occasions. Finally, cost, ease of use and attractive packages are key factors affecting FDWs’ selection of mobile services.
