The expansion and the reliability of mobile technology in Sub-Sahara Africa - as well as elsewhere - opened up diverse opportunities. For instance, the access to learning material, conduction of commercial activities, promotion of agricultural activities, enhancement of governmental transparency, support of healthcare practices, etc. To harness the existing mobile infrastructure, diverse users are looking for effective and efficient ways, for instance, the Bayam Sellam in Cameroon. Bayam Sellam refers to people engaged in trade between rural and urban markets. This work analyses the usage and development of information and communication technology in Sub-Sahara Africa in general, and the mobile technology and its constraints in particular. An efficient use of the mobile technology depends on appropriate mobile services and applications. These should produce and use local digital content, so as to enhance the use of the existing mobile infrastructure and contribute to satisfy the user's needs. As a case study, we focus on a tailored mobile commerce solution for Bayam Sellam and other related stakeholders such as the governmental department for price regulation.
