This is a randomized controlled pilot study with a parallel 2-arm design. It will evaluate the effect of a text message-based strategy to improve retention in HIV care at the study clinic, compared to the standard of care. Trained counselors will deliver the text messages. After a block randomization, the trained counselor (a nurse) will send the first welcoming message to participants in the intervention arm. The nurse will send 2 tailored text messages per week. In addition 2 to 4 days before an appointment, the nurse will send a message reminder. In addition, the nurse will have bilateral communication with participants using text messages according to their needs. The participants of the intervention arm will interact with the nurse during 3 months with a semi-structured strategy, that is, with template text messages (predesigned) and open messages (for which the nurse will be trained). Three and six months after started the intervention the variables of interest will be assessed.
