Will Unicom receive a text message when checking the bill?

Unicom will send a short message to inform the mobile phone when inquiring about the bill.

The content of the short message is as follows: Dear users, you used the detailed list inquiry service through the online business hall at a certain time in a certain month. Thanks for using it. (There will be differences in different regions)

This is the setting made by China Unicom to protect users' privacy. Knowing the service password can't cancel SMS notification.
