Why can't my mobile phone use MMS?

Firstly, confirm that the mobile phone terminal supports MMS service (refer to the mobile phone manual), and secondly, the mobile phone number needs to be enabled with Internet access function and SMS function (if the Internet access function is not enabled, users cannot send and receive MMS; If the SMS function is not turned on, the user cannot receive MMS); Please confirm the settings related to the mobile phone MMS function, or contact the telecom customer service for help. When the network is normal, you should be able to use MMS normally. 1) If the user can't send MMS, you can ask the user to check whether it is online normally to judge whether the network environment is normal at that time. 2) If users can't receive MMS, they can inquire through 2.0 System-Online Processing-SMS Service-SMS Send (clear the service number and check the terminal number).
