Can the police send a text message warning without any evidence to investigate?

Public security organs may also send short messages to individuals, but the contents of short messages are mainly reminders, thanks and blessings, and the follow-up treatment after the alarm, so it is impossible to send warning short messages.

Warning is a kind of public security management punishment measure, not a criminal punishment measure. If the public security organ gives a warning, there will be no criminal record, and the warning will not be sent to individuals privately in the form of short messages.
