Will travel itinerary, who inquired by SMS, be blocked?

I found it by text message. travel itinerary won't stop. Users who query travel itinerary by SMS can query the city information they have visited or stayed in 14 days by sending SMS.

China Mobile sends CXMYD to 10086/ China Unicom sends CXMYD to 100 10/ China Telecom sends CXMYD to 10000.

SMS Travel Card Settings

The SMS travel card is set to meet the judgment condition of staying for 4 hours. Therefore, in a day, the earliest and latest call or traffic usage records need to span more than 4 hours, such as once at 7: 00 am and once at noon 12, to meet the requirements.

If you are a user with a number, there is a certain time difference between user information synchronization and itinerary calculation. Usually, the calculation of travel information will be delayed by 1 to 2 days. If you still can't find the itinerary, you can contact the customer service of your own operator in time, such as Telecom 10000, Mobile 10086, Unicom 100 10.
