"Especially if you start talking about low-income people, cell phones are the indispensable tool for reaching them and engaging them about their health," said Paul Meyer, president of Voxiva, a company which operates health texting programs in Africa, Latin America and India.
Studies in those countries have shown that periodic texts can reduce smoking and other unhealthy behaviors in pregnant mothers.
