The purpose of this exploratory study is to better understand the mobile phone usage pattern among street vendors in the Dar Es Salaam city. The survey data were collected from 174 mobile street vendors in Dar Es Salaam where stratified and convenience sampling were employed. Data were subjected to detailed exploratory analysis through descriptive procedures, and the reliability analysis was carried out by using Cronbach’s alpha. The findings show that, among street vendors, mobile phone is commonly used in social perspectives and little in business specifically for M-money and business communication. Furthermore, the results show low perceived difficulties and high perceived benefits of using mobile phones, meaning that there are opportunities of transforming street vending business using mobile technology. Generally usage is very basic and the true benefits of mobile phone access have not being realized by street vendors.
