3.CRBT is the abbreviation of "Color Ring Back Tone", which is a service for called customers to set special sound effects (music, songs, story lines, character dialogues) 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, it will no longer hear the "beep" ring back tone, but provide a piece of music or a greeting for the calling customer to replace 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.
