The government of Tanzania plays a great role in promoting mobile phone use in the country. Available statistics show that more than 50 million sim cards were registered by June 2022. Also, over 60% small-scale farmers have a mobile phone, which makes Tanzania one of the countries in Africa with the highest number of mobile phone users in the agriculture sector. Various mobile phone services platforms have been established to link farmers to market information, including the Mobile Kilimo Platform, the T-Hakiki (TCCL) by dialling a USSD code *148*52#, Z-Kilimo (Vodacom) by dialling *149*50#, and Tigo Kilimo, and M-Kilimo by dialling *152*00#. Therefore, this paper examined factors for using mobile phone services to access agricultural market information among smallholder framers in Bahi and Mvomero Districts, taking Mkindo and Bahi wards as a case. A sample of 210 participants was used (207 respondents and three key informants). The study used a cross-sectional design that blended qualitative and quantitative methods. Data were collected from primary and secondary sources. The logistic binary regression model was used to analyze quantitative data. The qualitative data were analysed through thematic (content) analysis. The findings from the study indicate that the use of mobile phone platforms to access market information among smallholder farmers was significantly associated with network availability, language, digital knowledge, sex, and farmer’s experience than the farmer’s education level.
