With the increased prevalence of cellular phones, mobile technology provides an important tool to reach underserved populations in low to middle income countries. mHealth interventions offer promise to improve maternal child health throughout the reproductive health continuum if they contribute to increasing skilled birth attendance, family planning and exclusive breastfeeding. We propose a randomized clinical trial to determine effect of using mobile phones to deliver SMS (one-way) versus an interactive SMS dialogue (two-way) on uptake of reproductive and neonatal health services and maternal and infant outcomes
