Zumbido allowed its 40 test users of diverse backgrounds to communicate about the daily challenges they face living with HIV/AIDS. Unlike other hotline or support mobile phone services, where a user calls one person for help, Zumbido functioned as a network, with each text message sent to every member of the support group.
Zumbido -- "buzz" in Spanish -- provided its 40 participants with mobile phones and unlimited text messages. The large group was broken up into four smaller groups of 10. Each group had a mix of different types of people from urban and rural locations, all from the Mexican state of Jalisco.
