What is the reason for the query failure of communication big data travel card? -Sorry, what should I do without your travel data?

1, the trip data of XX cannot be found.

Have you stayed in XX for more than 4 hours in the last 7 days, and have you used your mobile phone to make calls or used mobile traffic during this period? If the mobile phone is not turned on during the stay, no signaling data will be generated, and the itinerary cannot be determined and will not be displayed.

Stay in XX for more than 4 hours in 2.7 days.

At present, there are too many requests from users all over the country in a short period of time, so it is recommended to wait for a while before trying to obtain them.

In addition, according to the national epidemic prevention requirements, new card users can only use the itinerary inquiry service after 7 days.
