Hello, everyone. The meeting will answer your questions. Wechat how to query 14-day personal track, 14-day track number has something to do with Wechat this many people do not know, now let's take a look at it!

Answer:

1. The personal track query is determined according to the position of the mobile phone, which is based on the distance between the transmitting position of the mobile phone signal and the receiving signal base station, and has nothing to do with switching WeChat. In order to support the resumption of work and production and help Hong Kong users prove their recent visits, under the unified organization of the Ministry of Industry and Information Technology, the three major operators of China Telecom, China Mobile and China Unicom have officially launched SMS inquiry "itinerary" services to mobile phone users across the country.

2. Personal track query is described as follows:

3. The personal track authentication queries of the three major operators are free and open, but it should be noted that they can be queried up to 10 times a day; according to the communication protocol, when each mobile phone user uses the communication service, the mobile terminal needs to connect with the base station at all times to verify the user's identity (code number information), so as to achieve communication routing and connection. The mobile phone card is the signal in the normal state, and this signal source is the service life of the base station; for example, when the mobile phone is powered on, the card searches for the signal and connects to the base station, and the base station has a record of the mobile phone connection; all this can only be recorded when the machine is turned on. From this point of view, the location of the base station is a coordinate anchor, which can not only help mobile phone users know their location, but also help Beidou navigation system to improve the accuracy of positioning services. The personal travel card only shows the places you have visited in the last 14 days and will be updated automatically.

This is the end of this article. I hope it will be helpful to all of you.
