Problem or Need: 

In Africa alone, one million mobile phones are being added every week. The mobile phone is mostly being used as a person-to-person communication tool and that’s why the Dutch NGO Text to Change came up with the idea to use it as an educational tool on health. When TTC started in 2007 there were no case studies or proofs of concept on text message-based health education programs. TTC started a pilot in Uganda with the help of mobile phone experts, infectious diseases professionals and software developers; and has now expanded its program for a variety of clients and additional countries.

Brief Description: 

Text to Change (TTC) combines the need for innovative health education with the growth in use of mobile phones. Supported by African mobile providers, the Dutch Ministry of Foreign Affairs, FC Barcelona and other partners, Text to Change uses SMS to challenge mobile phone users on their health knowledge, refer them to HIV testing sites and gather sex and age data from participants which can be analyzed alongside the location of caller. Text to Change works location-based and is able to involve 20% of the local population in its quizzes. Data analysis show that 60% of respondents have basic knowledge on health with an average age of 19, and 45% female participation. Participants of these free multiple choice quizzes maintain their anonymity. They can win mobile phone minutes and soccer shirts as an incentive for participating. If a participant sends in a correct or wrong answer, he or she will receive a confirmation or correction SMS.
