Forty participants, non-adherent to HAART at study start, will be randomly assigned to either a 1) "Cell Phone Adherence Facilitator" group (intervention group) or a 2) control group. In the intervention group, a Cell Phone Adherence Facilitator will initiate a short (typically five minutes or less) contact Monday through Friday (excluding major holidays) with each participant to enhance their adherence to HAART. Occasionally, calls may be longer if crises arise that can be addressed by the Adherence Facilitator. Calls from the Adherence Facilitator will occur once or twice a day (depending on dosing schedule) and go on for 24 weeks in the intervention group. Calls will occur at a time soon after the prescribed dose is supposed to be taken, but also one convenient to the participant and the Adherence Facilitator.
