Is the short message of streaming media sent to the owner himself or to the user?

The COVID-19 Epidemic Prevention and Control Command was informed that sending big data epidemic information according to the mobile phone number is a spatio-temporal phenomenon. According to the relevant person in charge, the city is currently carrying out further flow adjustment work, using big data, "internet plus" and other technical means to screen relevant personnel. If the citizen's phone number and the number of confirmed cases stay in the same time-space grid (the range is 800 meters ×800 meters) for a period of time, they will receive an epidemic prevention and control reminder message.
