How does Apple's mobile phone refuse to flash messages?

1, contact the operator, describe the experience, and turn off the SMS or hands-free SMS function.

2. Short message service is a new short message service. When sending a flash message, the information content is directly displayed on the receiver's mobile phone screen, without opening it, and the information will not be automatically saved after reading.

3. There is no need to apply for or cancel the SMS service, just add the SMS service code 0 18 before the number of the SMS receiver to send it. M-Zone customers who use M20 card can also use it by operating to send flash messages or direct display short messages under the built-in menu of SIM card. It should be noted that the display, storage, forwarding and other operations of flash messages need the support of the receiving terminal.
