Why does 10086 always send me short messages in the afternoon 12 to report the traffic usage?

This is used by 360 traffic monitoring to check the daily traffic. After you click "Calibrate Now", it will automatically send out the inquiry information code, and then calibrate your current traffic according to the received reply. It can be changed to non-daily approval in the traffic monitoring settings of 360 Security Center, and China Mobile also has free daily traffic reminders. You can also unsubscribe from traffic reminders, daily reminders, weekly reminders and monthly reminders. If you need to cancel, you can send a short message "qxatltx, QXAZLLTX, QXAYLLTX" to 10086 to cancel, and the cancellation will take effect immediately. Sending text messages is free.
