shouldn't they be focused on children and programs about children health, safety and education?

Mobile improves all of the above. http://www.chron.com/business/article/Urgent-tweet-in-Kenya-...

i certainly agree. but focus for this topic coming from unicef, is kinda interesting to me.

Often times the most obvious/direct methods of addressing these problems fail spectacularly. Put a different way, simply dropping tons of food on a population doesn't benefit their ability to become sustainable. I'm not suggesting we cut off food aid, but rather trying to understand how mobile phones make a good investment for an organization like UNICEF.
