"Youth and young adults (15-29) are often assumed to be leaders in mobile phone use, but this is not entirely the case in Zambia. While those 15 to 29 make up the largest segment of overall mobile phone users, they do not show the highest rate of weekly (regular) users that is taken by those 30 to 44. Geographic Breakdown: There are substantial differences in rates of mobile phone use among Zambia's nine provinces. These differences reflect varying levels of human development around the country, but other factors come into play. Cost Factors: When respondents were asked to agree or disagree that "using a mobile phone is expensive," 63 percent answered in the affirmative. Even those residing in high-income households were more likely to agree than disagree with the statement. The same can be said for frequent mobile users, with some 52 percent of daily users and 53 percent of regular users agreeing or strongly agreeing with the statement that mobile phone use is expensive. Mobile Radio: A key feature of Zambian (and more generally, African) mobile phone use is an old-new media convergence phenomenon: handset-based radio listening. Among regular mobile users, a third said they listen to the radio via their handset on a weekly basis, and 25 percent said they listen on a daily basis. Unlike the use of mobile internet, radio listening is more evenly spread across urban and rural users. Mobile-based radio listening may also continue to expand; given that youth and young adults (YYAs) are currently the most likely to do so and thus will set the pattern going forward."
