My card is M-Zone Mobile. How can I set it so that there will be a text message for missed calls when the phone is turned off?

Hello, if you are a Jiangsu Mobile customer, you can activate the incoming call reminder service for 3 yuan/month. When your mobile phone is turned off or disconnected (in the basement/elevator), the incoming call will be transferred to the voice response system. Record the incoming call number. After you turn on the phone or the phone returns to normal, the call information will be sent to your phone as a text message. If you need to apply, you can bring your valid ID to the business hall to apply, or log in to the Jiangsu Mobile website with a valid service password to enter the business application page to select and apply. for your information. Thank you for choosing China Mobile.
