This document summarizes a cross-cultural study of mobile phone use by students with disabilities ages 15-25. It reviewed the top 10 mobile phones in several countries and identified common accessibility features. A questionnaire was sent to 220 students to understand which phones they use, difficulties experienced, and how features are used for communication alternatives, viewing, memory aids, finding information, organization, and more. Popular strategies from projects in Japan, the UK, and US were examined for their fit with available phone features.
