How often is the communication trip code updated?

The code is updated every day, from 8: 00 am to 10, and the data of the previous 14 days will be updated uniformly. Stay in a place for more than 4 hours, open the travel code with your mobile phone, and the system will automatically record it as passing by or sightseeing.

The "Communication Big Data Travel Card" service uses base station data. In order to ensure continuous communication and achieve coverage without blind areas, the signals of base stations at the junction of administrative divisions may cross-cover, resulting in deviation of results. In addition, staying in a city for less than 4 hours will not be recorded. Overseas travel records require you to use international roaming service when you are abroad. If the result is seriously deviated, please contact customer service in time.

The travel card can inquire about the domestic and international travel situation of the individual in the first 14 days. Accurate to all provinces and cities in China (staying for more than 4 hours) and abroad. For example, on September 15, calculate the travel data before September 15 14 (between 0: 00 on September 1 day and 24: 00 on September 14). Cities visited after 14 days will not be displayed (the query result may be delayed by one day).
