During the Ebola crisis in Western Africa, mHero, a mobile phone based communication system used basic text messages (SMS) to connect ministries of health and health workers in Guinea, Liberia and Sierra Leone, to coordinate relief efforts10. What the most successful mobile services and applications have in common is that they are basic, often using voice or SMS services, that are affordable, easy to use and require little bandwidth and work with feature phones and over the 2G network. The Internet can be accessed over 2G networks, but only at narrowband speeds (i.e., < 256 kbps) using technologies such as GPRS and EDGE.
