- Sending mobile phone owners updates on diseases via SMS.
- Letting health workers in Uganda log data on mobile devices from the field.
- In South Africa, the SIMpill is a sensor-equipped pill bottle with a SIM card that informs doctors whether patients are taking their tuberculosis medicine.
- In Uganda, a multiple-choice quiz about HIV/AIDS was sent to 15,000 subscribers inviting them to answer questions and seek tests. Those who completed the quiz were given free airtime minutes. At the end of the quiz, a final SMS encouraged participants to go for voluntary testing. The number of people who did so increased from 1000 to 1400 over a 6-week period.
- In the Amazonas state of Brazil, health workers filled in surveys on their phones about the incidences of mosquito-borne dengue fever.
