Study sites and population: In Zimbabwe, 81% of people already had mobile phone subscriptions in 2014 [83], indicating that the technology infrastructure exists and uptake is high. 2wT will be implemented in existing VMMC sites in the Chitungwiza District, a district purposefully selected for its high VMMC volume clinic locations. Chitungwiza District, a suburb of Harare, has an estimated 300,000 eligible, HIV-negative men ages 15-29; only 14% of eligible men have been circumcised to date. The investigators will implement 2wT in up to 5 ZAZIC VMMC sites in Chitungwiza, sites averaging 50-200 VMMC/month. About 80% of VMMC clients are surgical, rather than PrePex device-based, clients.
