Lessons learned brief for Ghana and Tanzania: External evaluation of mobile phone technology-based nutrition and agriculture advisory services

mNutrition was a five-year global initiative supported by the Department for International Development (DFID) between 2013 and 2018, organised by GSMA and implemented by in-country mobile network operators (MNOs) and other providers. The evaluation was carried out by a consortium of researchers from Gamos, the Institute of Development Studies, and the International Food Policy Research Institute. This briefing summarises key evaluation findings and presents lessons learned on three key topics: 1. The design and implementation of mobile phone-based information services to promote behaviour change; 2. Building a commercially viable business model for mobile phone-based information services; and 3.
