What should I do if there is an error in the travel itinerary display server?

The communication travel card is a must-use voucher when traveling far away. Without this voucher, it will be very inconvenient to travel. Many people find that their communication travel cards are displayed incorrectly when they are used. In this case, you can refer to the following methods:

1, China ICT Institute

Send an email to China ICT Institute with your email address to explain your situation, and then wait for a reply. After receiving the reply, follow the email prompts and log in to the communication big data travel card again half an hour later. Note that the working hours of China ICT Institute are from Monday to Friday.

2. Operators

Because we need to get rid of the wrong city information, which belongs to the operator, so we call the corresponding operator to find human customer service to help and explain the situation. If it is not resolved within one or two hours after the call, you can try to call several times until it is resolved.

Technical principle of travel card:

The communication big data travel card analyzes the signaling data of the mobile phone and obtains it through the location of the base station where the user's mobile phone is located. The collection, transmission and processing of signaling data are automatic, with strict security and privacy protection mechanisms, and the query results are available in real time, which is convenient and fast.

The data of the communication big data travel card can be used nationwide, achieving full coverage of a national network, and can also query the international travel of my domestic mobile phone number. On the premise of ensuring user information security, these will provide scientific and accurate technical support for epidemic prevention and control, resumption of work and production, road traffic, entry and exit, etc.

The data source of location query service provided by travel card is mobile phone signaling data, which is obtained through the location of the base station where the user's mobile phone is located. In order to ensure communication continuity, realize coverage without blind areas and provide better communication service quality, the signals of base stations in the two places at the junction of administrative divisions may cross-cover, resulting in deviation of results.

This may happen if the user lives near the city boundary or travels long distances by car or train. ? The query results show that the provinces, cities (domestic), countries and regions (international) visited are divided into three cards: green, yellow and red, and the rules will be adjusted in real time according to the actual situation. The user's trip calculation for the first 14 days was completed in the background of the operator, and the result was delayed by 1 day.
