Considering recent developments related to government monitoring of the internet in Cambodia and a renewed push in civil society to improve access to information for Cambodian citizens, we wondered: what do Cambodian owners of smartphones do on the internet? This article reports how respondents use the Internet, smartphone use, perceive benefits of the Internet, and social media use. A survey was developed iteratively by the research team, with ongoing support from members of the in-country team located in Phnom Penh, Cambodia. A planned missing data design was utilized. The survey was disseminated to 35,000 Cambodia smart phone users. 429 responses were gathered on questions focusing on the personal, political, social media activities on the internet. This study adds to the growing body of knowledge on how various societies are getting access to the internet and what they do when they are on the internet.
