Introduction: Lack of availability of health workers, poor infrastructure, vast geographical area, and unafford- able transportation costs are limiting factors for the utilization of maternal health services in developing countries. However, the high penetration of smart phones and internet usage provides an opportunity to increase access to healthcare. The purpose of this study was to explore the supporting factors in the use of smart phones as a medium for health services delivery for pregnant women in rural Indonesia. Methods: A qualitative study with a case study design was conducted in 2018 in rural area involving 16 pregnant women with smart phones and 6 village midwives. This study used purposive sampling and in-depth interviews of individual respondent using a semi structured interview guide, following which a thematic analysis was conducted. Results: We found 4 main themes, namely smart phone ownership, understanding the benefits and functions of smart phone, the pattern of using smart phone and access to internet networks as well as 11 minor themes. The study found that most of the pregnant women had a smart phones and internet access, and able to use them in daily activities. Conclusion: Despite the significant efforts made to develop and expand health services for pregnant women in rural areas, the coverage for maternal health services at health centers is still low. Access to antenatal care in rural areas can be improved via smart phones equipped with health applications developed in accordance with social characteristics.
