Twenty-three-year old Rio Safiyanto sells face masks, or coverings, for about 30 cents each in central Jakarta, Indonesia. He makes enough money to buy a cell phone that permits him to visit websites. He says every average person has a cellphone. He likes having one because he can talk to his family when he is away from home. And, he is especially pleased that he can use it to listen to music.
