What does it mean that the communication itinerary card applet shows illegal access?

Because the bank card business uses base station data, in order to ensure continuous communication and achieve no blind area coverage, the signals of two base stations located at the intersection of administrative divisions may cross coverage, resulting in deviation of results. In addition, staying in the city for no more than 4 hours will not be recorded. If there is a big deviation in the test results, please contact customer service in time for handling.

The iteration card is based on telecom big data, and the interface is provided by three operators. Just fill in the mobile phone number, verification code and confirm the authorization. You don't need to fill in your ID number and home address, and you don't collect other personal information.
