WHO is working with Viamo, a global social enterprise improving lives via mobile, to provide WHO’s COVID-19 information, including vaccines, to the hardest to reach populations, in their languages, through the mobile phones they own. This includes people with simple phones (feature phones) or with limited access to the internet. Since the onset of COVID-19, Viamo’s 3-2-1 Service has become a trusted, toll-free source of life-saving COVID-19 health information for people in 19 countries. Listeners dial in and access important messages that help them make better informed decisions to live healthier lives.
