The mobile phone receives a friend's Didi trip.

In this case, after Didi Chuxing adds an emergency contact, the added mobile phone number will be notified by SMS to ensure that it becomes an emergency contact of others.

When using Didi to travel, after pressing the "one-button alarm" button, the related emergency contact phone will receive the message sent by Didi, mainly including the license plate number, vehicle model and location.

One must be vigilant when taking a taxi. There are some precautions to learn: 1. After getting on the bus, it should be no problem to tell your family the license plate number of short-distance driving in the city, but if you cross the city or pass through remote areas, you must do it. If you take a taxi, write down the license plate number in advance. If it is Didi, you can see the license plate number on the phone. When you get the license plate number, you must call your family or friends, and it must be very loud (don't just send text messages), so that the driver can hear you.

2. Always turn on navigation: there is a navigation system in the mobile phone. If it's a long trip, don't just listen to music or sleep in the car. Check the navigation occasionally to see if the driver deliberately detours. If so, immediately warn the driver to take the normal route, otherwise ask to get off, or complain or even call the police.
