What is the boot reminder service? How to open it?

Hello, users can open it through channels such as telecom customer service and telecom business hall.

Boot reminder is a call reminder service for China Telecom Tianyi mobile phone users.

Power-on reminder refers to the service that provides the calling user with the power-on information of the called user after the user's voice call fails (because the called user is turned off or not in the service area). That is, the user who customizes the power-on reminder is the calling party who calls the called Tianyi user. When the called party is unable to connect, when the called party starts up or returns to the service area, the startup reminder platform will inform the called party of the startup information by SMS in time.
