Who can tell me: what are CRBT, MMS and ringtone?

Analysis:

CRBT- what is crbt?

A: CRBT service is a new Monternet service recently launched by China Mobile. After the user opens this service, when the other party dials the user's mobile phone to wait for the connection, it is no longer the ring back tone of "beep … beep …", but the music or sound effect set by the user.

When the CRBT goes into battle, you can say goodbye with the sound of "DuDu ……" from now on, so that communication can start with wonderful music, and there will be a relaxing moment between busy work, which is also a new way for you to express your feelings if you love life.
