How long does it take to change the code after receiving the text message for seven days?

In this epidemic, the "yellow code" personnel "have three inspections in seven days" for free via SMS. The Municipal Health and Health Commission reminded that in order to avoid affecting the later travel, the "yellow code" personnel should continue to complete the next two tests as required after the first test to restore the "green code". It is reported that in this round of epidemic prevention and control, the Municipal Bureau of Statistics used 5G SMS to send epidemic prevention reminders to health code "yellow code" personnel and key populations. After receiving the 5G message, whether the citizens read the message and other data will be sent back to the background. The public can also report whether the feedback has been tested for nucleic acid, check the address of the nucleic acid detection point, and even navigate to the detection point with one click.
