What does the doctor mean by short message?

By sending text messages or phone calls, criminals claim that they can provide medical supplements for victims, induce victims to fill in personal information on fake websites or apps, and then defraud victims of their money.

Medical supplements, such as text messages or telephone calls, are usually disguised as formal medical institutions or government departments to attract the trust of victims. However, the short message of medical supplement money is false information, so victims should be vigilant, don't believe it easily, and avoid being deceived.
