After applying for the power-on reminder service, what SMS instructions should be sent to clear the blacklist?

Tianyi users send the command code "QXHMD" to the short hall port 10659114114 to clear the blacklist.

The power-on reminder is a call reminder service provided to callers of China Telecom's Tianyi mobile phones. The fee is 3 yuan per month.

The power-on reminder is a service that provides the calling user with power-on information of the called user after the user's voice call fails (because the called user is powered off or is not in the service area). That is, when the user who customizes the power-on reminder is the calling user and calls the called Tianyi user, and the called user cannot be connected because he is in an unreachable state, when the called user turns on the phone or returns to the service area, the power-on reminder platform will notify the called user via SMS. The power-on information is notified to the calling user in time.
