The CellularBroadcasting Service, or CBS, enables government agencies to transmit emergency alert text messages on natural or manmade disasters to cell phones through mobile telecom carriers in Korea. Residents who receive COVID-19 emergency texts can quickly check if they have been anywhere that overlaps with the movement of a confirmed patient, allowing them to get tested quickly if necessary. In this way, the CBS contributes to slowing the spread of the Virus across the nation.
