Sending and receiving money by text message. Sharing crop prices. Just talking to a loved one far from home. These are some of the ways that mobile phones have changed lives in developing countries. Another way is through e-health, electronic health services.

One example is a telephone hotline in the Democratic Republic of Congo. Callers can receive information about family planning and the prevention of unwanted pregnancies. They are able to speak privately with trained operators about contraceptive methods and about health clinics.
