What is full-time mobile phone service?

Full-time calling is a missed message reminding service provided by China Mobile. It can make you miss any phone call, so that when the incoming call cannot be connected normally due to reasons such as power off, busy line, out of service area, etc., the incoming call will be transferred to the full-time communication system, and the system will provide the called user with called notification, voice multimedia message and other services according to the operation of the calling user.

Full-time calling service provides two functions: called notification and voice MMS.
