How many hours will the trip code show the city?

Unless you stay for a very short time, less than 4 hours, you may not show where you have been, but this possibility is relatively low. Relevant data is updated every 14 days.

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 living for 4 hours. There are also some tips when making a phone call: within one day, the time span between the earliest call record and the latest call record needs to be more than 4 hours (for example, once at 7:00 am and once at 12:00 pm) to meet the requirements and display the itinerary.

The same principle applies to the use of traffic. The verification code of the communication travel card is issued by the SMS gateway of each operator. If the number of requests is too large in a short time, resulting in SMS congestion (such as peak hours), you will not receive the verification code.
