I received two abnormal text messages one day.

If you receive abnormal text messages twice a day, you should distinguish the authenticity of the messages. There is an unknown URL link after fraudulent mixed sending of abnormal short messages. If you click on it, you will get a mobile phone virus. Real text messages will only remind residents of anomalies. After receiving the recheck message, on the premise of personal protection, go to the nearest community nucleic acid sampling point as soon as possible, and conduct a single-person and single-tube sampling recheck with SMS.
