Mobile value-added services (MVAS) represent a growing collaboration between the private sector and the development community. In this paper, we examine one such MVAS, the Nokia Usaha Wanita service running on the Nokia Life+ platform in Indonesia, and we assess its impact as an innovative means for the economic empowerment of businesswomen. Data were gathered through 282 telephone interviews with a nationwide random sample of women who subscribed to Usaha Wanita. Our research found evidence that subscribers derived economic benefit from using the service. Subscribers reported that their business profits were greater, because of what they had learned from reading Usaha Wanita content. Women who were subscribers also had higher “good month’s” profits as well. Increased profits were positively correlated with frequent reading of the tips and information provided by Usaha Wanita and subscriber perception that the service was useful for business. Women who exhibited entrepreneurial optimism also had greater business profits. Findings suggest that entrepreneurial optimism amplified the effect of mobile phone use on profits.
