Mobile-government (m-Government) services adoption is being advanced as an alternative solution for addressing challenges faced by electronic-government (e-Government) adoption in marginalised communities. However, factors of m-Government need to be understood if it is to be adopted by marginalised communities. There are suggestions that many contextual factors affect to the adoption of m-Government services. In this study, factors of m-Government in Oniipa, a marginalised rural community in Namibia are researched. Results show that security, technology trust, ICT supporting infrastructure, usage experience, costs, awareness, skills for accessing m-Government, language literacy, training, perceived ease of use, perceived usefulness, social influence, perceived empathy and compatibility are critical factors of m-Government services adoption. The study findings shall be used to propel m-Government adoption in a Fusion Grid project that aims to address infrastructural challenges faced by marginal communities when adopting e-Government. Similarly, policy makers can draw lessons on m-Government adoption from this study.
