Research questions § How do Gambians use their mobile phones? § What patterns of mobile phone use are emerging? § How can single use patterns be explained by the influence of functional expectations, restrictions and norms? 7 th CMI Conference, 17. 11. 2014 4/13
Theoretical background § Innovation diffusion theory (Rogers 2003) § Media appropriaton (Silverstone and Haddon 1996) § Uses and gratifications (Rubens 2002) àMobile Phone Appropriation Model (Wirth et al. 2008) Dimensions of mobile phone use: - Object-related aspects of use: Frequency in which services such as voice communication or short messaging are used - Symbolic uses: Mobile as an aesthetic object with ringtones, fashion accessories 7 th CMI Conference, 17. 11. 2014 5/13
Theoretical background Daily social functions Modes of appropriation Professional functions Individual-hedonistic functions External restrictions Mobile use patterns Internal restrictions Subjective norms Demographic variables 7 th CMI Conference, 17. 11. 2014 6/13
Methodology § Data collection in the Gambia from 25 th Aug to 2 nd Sept 2014 § Standardized survey with face-to-face interviews § Two research sites: Kanifing (urban) and Pakalinding (rural) § Quota sampling based on age and sex § Interviews in local languages § Use of four-point scales, e. g. To what extent do you agree or disagree with the following statements? Strongly disagree -+ Using a mobile phone makes my life easier. □ □ □ 7 th CMI Conference, 17. 11. 2014 Strongly agree ++ □ 7/13

Descriptive data § 88. 8 % own a mobile phone, mainly in urban areas and among literates § On average, respondents hold 1. 8 SIM cards; the median number are 2 SIM cards § 2. 2 % use a postpaid billing method in addition to a prepaid phone use § Between 25 and 550 Dalasis are spent for mobile phone use per week; 40 % of the respondents spend more than 100 Dalasis (approx. 1. 80 Euros) § 38. 5 % share their mobile phone with other people, particularly in rural areas and among females 7 th CMI Conference, 17. 11. 2014 9/13

Conclusion § 3 different use patterns were found: Multimedia use, Calling, Beeping & playing § The calling pattern can be explained mainly by gender, the amount of money spent on mobile phone use as well as the experience of daily social and professional functions § The multimedia pattern can be explained by age and internal restrictions § Limitations of the study relate to the sample size and sampling method and the adaption of theoretical model to the Gambian context § Further research is necessary regarding the operationalizations of the variables and the examination of usage contexts 7 th CMI Conference, 17. 11. 2014 12/13
Conclusion § Do more research - to enquire about usage patterns and explanations of usage - to synchronize research between African countries § Recommendations: - Policies towards the inclusion of females and illiterates - Business models for professional and social uses of mobile phones 7 th CMI Conference, 17. 11. 2014 13/13
