A clinical study to evaluate the use of cell phones to support drug adherence and follow-up of patients taking antiretroviral therapy (ART) for treatment of HIV. The intervention involves health-care providers sending regular short-message-service (SMS) text messages to patients and following up their responses. The hypothesis is that the cell phone intervention will improve ART adherence and health outcomes compared with the current standard of care.
