Will the mobile phone record the trip code when it is turned off?

When the phone is turned off, the trip code will be recorded.

The travel code is also called "Traffic Big Data Travel Card". As long as you use your mobile phone, whether it's mobile, telecom or Unicom, you can accurately locate your position. When did you go there and when did you leave? You know the itinerary code. Travel Code Technology will collect positioning information in three aspects: base station positioning, satellite positioning and wifi positioning.

The first is the location of the base station. As long as the mobile phone has a mobile phone card plugged in, the base station with a signal can determine your location. In China, there is a base station every 1.5 square kilometers on average. Base stations will constantly send and receive mobile phone signals, and each base station has its own fixed and clear city ownership. This is easy to understand. When you are in Guangzhou, your mobile phone will be connected to the base station signal in Guangzhou, and when you are in Shenzhen, your mobile phone will be connected to the base station signal in Shenzhen.

The base station will use the unique IMSI number of the mobile phone to locate the mobile phone. In fact, "base station location" is a unique IMSI code based on mobile phone cards. When the mobile phone card is pulled out or turned off, it is impossible to escape the signal positioning. Then if I go to a very remote place, there is no base station and no signal, will I be unable to locate it? At this time, "satellite positioning" appeared.

Every mobile phone has its own GPS positioning system. As long as any navigation software is turned on, the GPS in the mobile phone will automatically "dock" with the satellite to determine the current position of the user, and then save the user's travel path on the mobile phone and upload it to the travel code system. Therefore, whether it is to turn off the phone or unplug the mobile phone card, you can't escape the tracking of big data!
