What if the communication travel card can't find the data?

The travel card analyzes the signaling data and bill data of the mobile phone, so the premise of having travel data is that you generate these signaling and bill data in the process of using the mobile phone. When you encounter this problem, you can try to make more calls, or turn off the Wi-Fi connection and use 4G traffic. Usually you can find the data the next day.

If you are a "number portability" user, there is a certain time difference between user information synchronization and travel calculation, and the travel information calculation will be delayed by 1-2 days. In addition, non-real-name registration system customers can't use the travel card service, and it takes 14 days to find travel information after new access or number change.

Precautions:

In order to avoid the location deviation caused by the coverage of base stations in surrounding cities, the travel card is set to meet the judgment condition of staying for 4 hours.

There are also tips for making phone calls: in one day, the time span between the earliest call record and the latest call record needs to exceed 4 hours (for example, once at 7: 00 am and once at noon 12) to meet the requirements and display the itinerary. The same is true with traffic.
