Why does China Telecom always send a message saying that I have been to medium and high risk and give it a yellow code?

According to the requirements of epidemic prevention and control, Telecom will send short messages to high-risk areas.

If you don't have to panic after receiving the text message, you should check your health code immediately. If it is a green code, you only need to carry out daily protection. If it is a yellow code or red team, it is necessary to report to the community (village group) and work unit in time and cooperate with the implementation of various epidemic prevention and control measures. In fact, China Telecom or China Mobile sent you a message to remind you that you have been to the epidemic-prone area. To be on the safe side, I hope you can do a nucleic acid test as soon as possible. This is a kind reminder, but it cannot be said that it is stipulated by law, so it is not illegal not to do nucleic acid testing. But if you don't cooperate with epidemic prevention measures, the consequences will be very serious.
