Will the itinerary code show where you have been when the phone is turned off?

The itinerary after shutdown cannot be found.

As long as the mobile phone is turned off (off), no matter whether the mobile phone card is removed or not, the mobile phone cannot communicate with the base station, cannot connect to the base station, and the base station cannot know that the mobile phone has entered its territory.

When you arrive at a place, big data will monitor your mobile phone signal and send you a text message to know where you have been. The trip code is guided by the Ministry of Industry and Information Technology, and the China Academy of Communications and the three major operators jointly launched a public welfare query service. From this we can see the authoritativeness of the itinerary code. You can rely on the base station signal tower to locate your mobile phone anytime and anywhere.

The introduction of the itinerary card is as follows:

It is possible that the local mobile operator has problems with the signal transmission tower due to some reasons, such as thunderstorms, typhoons, etc. In this situation, we can only wait for the operator to carry out emergency repairs before we can connect to the network.

The itinerary card is universal, safe and reliable, and the detailed query results are only displayed on the person's mobile phone; it is true and accurate, and the information is formed through the data of the communication network and can be updated automatically. There are 1.58 billion mobile users in the country, and all mobile phones including non-smart phones can use it.
