Failed to send verification code of communication big data travel card.

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. I suggest waiting for a while to try again.

In addition, if the user actively prohibits the value-added service, it needs to be reopened before receiving the verification code normally. If you still can't receive the verification code, please contact the operator's customer service immediately.

If you can't open the webpage during use, can't receive the verification code, or have problems with the itinerary inquiry, please call the customer service hotline of your operator immediately, or the familiar10000/10086/10010.

Note: The service data of "Travel Card" may be biased. Please pay attention to the use risks and make adjustments according to the actual situation. As a public service, travel itinerary can be used by users to prove their itinerary.

The management department can use the data of travel itinerary as a reference, but if the user can't find the data during the trip inspection or the query results don't match the actual trip, it is recommended to comprehensively judge the inspection results by combining the air tickets, air tickets or other supporting materials provided by the user.

Communication Big Data Travel Card is a free inquiry service for 654.38+06 billion mobile phone users nationwide, which is obtained by China Xintong Institute, China Telecom, China Mobile and China Unicom by using the "signaling data" of mobile phones. Mobile phone users can query all the city information they have visited in the previous 654.38+04 days through this service.

As of March 25, 2020, the cumulative number of inquiries has exceeded 450 million. The city names of high-risk areas are marked in red, and the remarks in brackets after the city names include medium and high-risk areas. Remarks are only used as travel tips and have nothing to do with health status.

On March 30th, 20021year, the national government service platform "Epidemic Prevention Health Code" has integrated the relevant information of "Traffic Big Data Travel Card", which can show whether the user has been to medium and high-risk areas and other travel information in the health code, and help the health code "one code pass".

On August 5th, 20021year, the joint prevention and control mechanism of the State Council held a press conference, and the "traffic travel card" provided more than1200 million times of inquiry service, which became an important means for all localities to do a good job in epidemic prevention and control.
