The percentage of Cambodian people who own at least one smartphone, a cellular phone that performs many of the functions of a computer, typically having a touchscreen interface, Internet access, and an operating system capable of running downloaded applications, was 39.5% in 2015, almost doubling the 2013 figure. Controlling for location and gender, 51.3% of people between the ages of 15 and 65 in 2015 had at least one phone through which it was possible to send and receive messages in Khmer script (a 65% increase from last year). The growth in the use of phones that can text Khmer script for women in the last year was 89.8%; while for men it was only 61.8%. The ability to display Khmer was also found to gradually increase with the level of education of the owner, from 33% of those who had no formal education to 69.2% for those who attended or have completed university.
