CRBT is the abbreviation of "Personalized Multicolored Ring Back Tone Service", which is a service that called customers set special sound effects (music, songs, story lines, conversations between people) for other calling customers who call their mobile phones.
After the called customer opens the CRBT service, when the calling customer dials the user's mobile phone to wait for the connection, they will no longer hear the "beep" ring back tone, but provide a piece of music or a greeting to the calling customer instead of the ordinary ring back tone.
The considerate CRBT service fully displays your unique personality and taste, and makes the simple communication process full of fun.
Features:
1, so that the calling user can enjoy pleasant music or greetings while waiting for the answer, instead of ordinary ring back tone;
2. Different ring-back tones can be set for different calling users and played for different time periods;
3. The ring-back tone content is stored on the network side, which has no requirement for the user's mobile phone terminal and has a wide customer base.
