Research shows: SMS services change lives

Amsterdam, March 30, 2016 – Mobile interventions have been rising in popularity in developing countries around the world. Mobile apps and services are extensively used by developing organizations and governments, and especially in Africa countless SMS services are launched to offer assistance in the fields of health, agriculture or financial support. It remains important to examine the actual effects of an SMS service: How much difference can an SMS make?

TTC Mobile, a Dutch social enterprise that offers the technology to implement mobile interventions in Africa, Latin America and Asia, contracted the impact researchers from Avance to find the answer to this question. The impact study resulted in eye-opening outcomes that make a great case for the social impact of mobile interventions. Participants from two different projects run by TTC Mobile were surveyed and/or interviewed and several partners of TTC Mobile were interviewed as well.

The ACLO project was an SMS service of the Connect4Change consortium that sent up-to-date market information to small-scale farmers in Bolivia between November 2013 and December 2015. Healthy Pregnancy, Healthy Baby SMS Service is a currently running service of the mHealth Tanzania partnership that sends health information to pregnant women, mothers of newborns and male supporters since December 2012. 116 farmers of the ACLO project in Bolivia and 374 subscribers of Healthy Pregnancy, Healthy Baby in Tanzania were surveyed and/or interviewed. The results clearly show the great value of mobile interventions:


Mobile interventions led to behavioral changegr 1

In terms of behavioral change, nearly all of the participants indicated that the text messages they received had a direct effect on their behavior. 92% of the farmers adjusted the prices of their products based on information they received, whereas 94% of the Tanzanian women and their male supporters changed the way they took care of themselves during pregnancy. For example, they visited the clinic more often or increased their intake of iron folate tablets.

“The doctor had forgotten to prescribe iron pills but after receiving the text I was able to remind the doctor.”


Mobile interventions improved conditions of end usersgr 2

80% of the farmers said that their income had improved due to the SMS service. In Tanzania, 93.2% of the participants said they gained knowledge from the text messages and 94% of the participants felt like the text messages increased the confidence in their own and in their baby’s health.

“My wife was shy to ask questions concerning the baby’s health and so the messages received were very impactful.”


Mobile interventions have great reach and are cost effectivgr 3e

In interviews, clients indicated that the mobile interventions of TTC Mobile reached more people than the traditional methods they had used previously and that they were better at reaching participants in rural, hard-to-reach areas. Also, clients indicated that the mobile interventions of TTC Mobile were more cost effective than methods that clients applied previously.

”Mobile interventions gave a total different dimension to our project: more reach and faster, more agile and real-time data.”


Research shows: an SMS can change lives. Not only did the text messages sent in these two projects result in better informed end users, nearly all of the end users directly applied their newly gained knowledge. According to the partners of TTC Mobile, mobile interventions appeared particularly more efficient than alternative methods, with regard to cost and scale.
