How to check travel itinerary's time record?

I can't find it at the moment. Under normal circumstances, the mobile phone passes through a place and stays for about an hour, and there will be a track display.

The user's number can be used to evaluate whether the close contact population appears in high-risk areas, and also to evaluate the user's location and how far it is from the nearest epidemic community. In addition to telecom mobile phone users, mobile phone users and Unicom mobile phone users can also query personal activity tracks.

The three major telecom operators all said that roaming information only provides information about passing cities, and does not provide accurate location and stay time. This business is a public service, and the query results are for reference only, not as the final judgment basis.

We still use these methods to make inquiries: SMS: when using the web version of travel card, WeChat applet or APP, in case of unstable service such as network error, send SMS CXMYD to the affiliated operator (telecom10001mobile 10086/ Unicom100/kloc-). In this case, you can try to make more phone calls.
