If you receive a short message with the number 1 10 120, it must be true.

Not necessarily. "Pseudo-base station", that is, illegal radio communication equipment, has the function of searching mobile phone user information and forcibly sending short messages to unspecified users' mobile phones. During use, it will illegally occupy the public mobile communication frequency and partially block the public mobile communication network signal. Within 500 meters, the mobile phone will lose its signal instantly and be forced to receive short messages. So, it may not be true. In case of any situation, you should verify the information with the local public security organ.
