How does the itinerary code know which places you ve been? Can I still find my phone after it is tur

The main thing is that there is a positioning record, when the mobile phone is turned on, there will be a record of the trip, and the signal strength of each city is different, so you can know which cities you have been to. There is no way to find it, and after the phone is turned off, the location information will be turned off.

This is because we have a positioning function in our mobile phone, as long as it appears in a place, turn on the positioning function, and let the formation code be detected; You can also check it after the phone is turned off.

Because your mobile phone is positioned, there will be relevant consumption records or payment records in different places, and then the mobile phone will transmit this information through GPS; It can still be found after the shutdown.

There will be no trip recording after the phone is turned off. The principle of mobile phone positioning is to use the base station to measure the distance of the mobile phone to determine the location of the mobile phone, and the accuracy of this positioning method is very dependent on the distribution of the base station and the size of the coverage.

The more base stations around, the higher the accuracy of the positioning effect, the positioning method based on the GPS module is through the GPS module on the mobile phone, send their location signal to the positioning background to achieve mobile phone positioning, with the widespread popularity of navigation and map software, the built-in GPS module has become a must-have function of all smart phones, and users can choose to turn it on or off.

Precautions for personal itinerary codes.

The person in charge of the relevant unit is the first person responsible for the implementation of the "two codes" management, and should arrange personnel to check and register all entering personnel, and those who find "red codes" and "yellow codes" or have symptoms such as fever and cough and cannot show the "two codes" shall report to the unit and the local community (village) in a timely manner in accordance with the relevant provisions of epidemic prevention and control.

Because the positioning record of the travel card is located in real time according to the trip, it cannot be located after the shutdown.

If the mobile phone does not turn on the positioning, the itinerary can still be checked.

Because querying the trip data is not based on your location, but according to which city your mobile phone signal is connected to. So even if you turn off the location of your phone, you can still query your trip information. Unless you keep turning off your phone, you won't be able to check your itinerary.

Only by unplugging the ** card can still be checked. Unless you remove your SIM card while unplugging your phone's battery, geographic information will be known to interested parties through your phone, no matter where you are.

In real life, the smartphones that everyone commonly uses now are basically all-in-one machines, and the battery of the mobile phone cannot be taken out under normal circumstances. Many apps can also be used to access the Internet even when the phone is turned off. As long as the mobile phone is turned on, it will try to access the base station, and once the base station recognizes the mobile phone, even if there is no SIM card, it can also be associated with its relevant information through the mobile phone's unique identification code IMEI number.

It cannot be closed.

Because after the phone is turned off, the positioning function inside and the corresponding software have stopped working. There is no record of the complete incoming, so it is impossible to find it.

The travel trajectory is a record of the driving trip of the car destroyer, most of which are recorded on the driving recorder, and you can know the place where the car has been through the record.

At present, you can only see the cities you have visited on the itinerary code page, but you cannot see the specific location.

Communication big data itinerary card.

It is by the China Academy of Information and Communications Technology.

United China Telecom.

China Mobile and China Unicom, the three basic telecommunications companies, have obtained free query services for 1.6 billion mobile phone users across the country through the location of the base station where the user's mobile phone is located, which is an upgrade of the service that previously queried the itinerary through SMS.

Based on telecom big data, the "communication big data itinerary card" is provided by the three major operators to provide the interface, only need to fill in the mobile phone number, verification code and confirm the authorisation, no need to fill in the ID number, home address, carry the jujube does not collect other personal judgment information, the operation is more simple and safe, and fully protect the user's privacy.

The communication big data itinerary card analyzes the "mobile phone signaling data", which is obtained through the location of the base station where the user's mobile phone is located, and the collection, transmission and processing process of signaling data is automated, with a strict security and privacy guarantee mechanism, and the query results are available in real time, convenient and fast.

The data of the "communication big data itinerary card" can be used nationwide, truly achieving comprehensive coverage of one network across the country, and you can also query the international itinerary of your domestic mobile phone number.

On the premise of ensuring the security of user information, these will be for epidemic prevention and control.

Provide scientific and accurate technical support for the resumption of work and production, road dismantling and traffic, entry and exit, etc.

The location query service data provided by the itinerary card** is "mobile phone signaling data", which is obtained from the location of the base station where the user's mobile phone is located.

In order to ensure continuous communication and achieve coverage without blind spots.

Provide better quality of communication services.

The signals of the two base stations at the junction of administrative divisions may overlap, resulting in deviation of the results.

This can happen if the user lives close to the city boundary, or if they drive long distances, take a train, etc.

Shutdown can check the travel track.

After most phones are turned off, a small number of programs are still running. So shutting down doesn't mean that all programs are stopped. If the phone has the function of turning off to find the device, it means that the phone has a separate chip, which is used to prevent the phone from being lost when it is located.

So it's still possible to check the trajectory of the trip.

I advise everyone not to have such thoughts, because this is not only futile, but also violates the epidemic prevention regulations and creates hidden dangers to the society.

Itinerary Code Introduction:

The itinerary code began to appear in February 2020, and this itinerary code was issued by the Ministry of Industry and Information Technology of China.

Guidance, by the China Institute of Communications, the three major service providers and other strong joint launch of the national itinerary query service. It is used by 1.6 billion mobile phone users in the country.

That Chinese population.

There are only a little more than 1.4 billion, and these 1.6 billion mobile phone users obviously represent one person with two phones, or even one person with three phones, and now buy SIM cards for mobile phones.

It must also be real-name, so it is not difficult to match mobile phone data and people one by one. Because it is impossible for us to go out without Chi's mobile phone, and as long as we bring our mobile phone, we can record.

No, the itinerary card has been offline on December 13, 2022.

It is not possible to check the itinerary after the shutdown.

As long as the phone is powered off (powered off), the phone cannot communicate with the base station, cannot connect to the base station, and the base station cannot know that the phone has entered its territory, regardless of whether the phone card is unplugged or not.

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 itinerary code is provided by the Ministry of Industry and Information Technology.

Under the guidance, the three major operators of the China Institute of Communications jointly launched a public welfare inquiry service. It can be seen that the authority of the travel code can be relied on anytime and anywhere.

Locate your phone.

The itinerary card is described as follows:

It may be due to some kind of land reason by the local mobile operator, such as a thunderstorm.

Problems with signal towers, such as typhoons, can only be connected to the network after the operator has to wait for emergency repairs.

The itinerary card is universal, safe and reliable, and the detailed query results are only displayed on my mobile phone; True and accurate, information is formed through the data of the communication network, which can be automatically updated. There are hundreds of millions of mobile users in the country, and all mobile phones, including non-smartphones, can be used.
