Use Viamo to:

Only Viamo offers this service and experience.
  • Share valuable information with anyone who owns a phone in their language of choice.
  • Set-up hotlines, infolines, behavior change communication campaigns, and subscription services.
  • Use a combination of channels (voice, SMS, USSD, web app, IM bot, etc.)
  • Personalize the listener’s experience based on complex conditional logic and past behavior.

Don’t just send information; ask your listeners if they understood the information, if they intend on using the information, and what other topics they would like to hear about.

Behavior Change Communication campaigns

Spread valuable information with the general population through mobile — independently, or in combination with radio and TV outreach. Call your audience or let them call in to a toll-free hotline at their moment of need.

Example users: UNICEF, Population Services International (PSI), Fidelity Bank.

Staff training

Train your field employees through their mobile phones – independently, or in combination with in-person activities. Monitor their listening rates, as well as their answers to quizzes. Reward them with points, badges, airtime or mobile money.

Example users: National Democratic Institute, Center for Disease Control and Prevention, Omidyar Network

Incentivize and monitor behavior change through call reminders, SMS vouchers, airtime transfers and mobile money. This, combined with mobile surveys, allows you to measure the precise impact of your marketing on household activities, in real time.

Example users: AIDSFunds, World Bank, Oxfam

Subscription services

Send valuable information to listeners through their mobile phones over many weeks and months. The information will change over time as the context of the listener changes. This includes: farmer calendars, maternal calendars, voter education, disaster preparedness, and more.

No one but Viamo has the experience and features to implement subscription services as effectively, with our data dashboards, telecom partnerships, and global reach.

Example users: UNOPS, BRAC, Grameen Foundation.
