The EPS SOS member writes on WhatsApp to your organization's number, at any hour. 2. The assistant asks for the EPS SOS order and authorization before offering a slot. 3. It books on your calendar and confirms the appointment on WhatsApp, with the instructions. 4. The day before, it sends a reminder; if they can't make it, it reschedules and offers the slot to the waiting list. ## What each one is - Health insurer (EPS) in the contributory and subsidized regimes ### EPS SOS Servicio Occidental de Salud EPS S.A.
