Donghai Liu, founder of D.Phone, outlines trends in China's mobile consumer market. There are three market segments based on development: 1st class markets in major cities see competition from electronics stores while D.Phone maintains share; 2nd class capital cities have growing competition from stores; and D.Phone leads the 3rd class rural markets. Mainstream consumers are getting younger, aged 18-35, as rural areas urbanize and demand in smaller towns expands. Consumer needs are shifting from voice to mobile internet as services like music and video grow. D.Phone is expanding its marketing across print, social media, and public events.
