How to send short messages to the public security department by mobile phone?

1: In order not to disturb criminals and ensure personal safety, information cannot be edited in the car for the time being. Before you leave for home, you should edit the information on your mobile phone, such as which bus you are taking, and write down the departure time and arrival time clearly.

If you meet criminals on the road, you will send your pre-saved information to your friends or family as quickly as possible, asking them to call the police immediately.
