Among 145 individuals surveyed in Tanzania, 42% indicated willingness to test for HIV in response to a confidential, phone-based text message. On average, participants were likely to provide contact information for 1.5 members of their social networks, suggesting high feasibility and moderate acceptability of a novel mHealth HIV testing intervention.
