How to query the personal track of Telecom 14 days?

Hello, subject:

How does China Telecom check personal track?

1, edit the short message "last four digits of CXMYD# ID number" and send it to 1000 1.

2. After receiving the reply message from 1000 1, edit the short message "Y" and send it to 1000 1.

3. After receiving the reply message from 1000 1 again, you can check the places where the mobile phone number passed in the past 15 days.
