The "trip card" analyzes cell phone signaling data and billing data, so the premise of having trip data is that the user generates this signaling and billing data in the course of using the cell phone. The first thing you can do is to try to make a few more calls, or turn off the Wi-Fi connection and use the 4G traffic, and you will be able to find the data the next day without any problems

The trip card can't find out how to do the trip:

1, roaming in a different place, you need to make five phone calls a day for more than a minute, and then you have to wait more than 20 minutes between each call. The next day at about 9:00 mine was back to normal.

2, call someone else on the line, remember to get through, within 14 days there must be two outgoing calls at intervals of more than 4 hours, the latest one do not exceed 8:00 p.m., the day before the call, the next day at about 12:00 noon you can query the information.
