In an effort to contain Ebola, the International Federation of Red Cross and Red Crescent Societies (IFRC) has teamed up with local cellphone provider Airtel and the Sierra Leonean government to send health reminders via text message. 

Text messaging can be the best way to get crucial information to people in a country where only 9 percent have cellular Internet access. However, the use of text messaging to respond to a humanitarian crisis or as part of a development initiative is nothing new – this just the latest example of using cell phones (not just smart phones) in humanitarian response (it’s a tool that’s been used since the 90s, believe it or not!).
