What is a ringtone?

CRBT is a kind of ringtone. Compared with the traditional ringtone, it can not only play music, but also play some songs, movie lines, famous sayings and aphorisms, which makes the ringtone more colorful. The emergence of CRBT can be traced back to 2003, when China Mobile launched its first CRBT service, which was quickly sought after by users due to its unique nature and personalized needs. At present, all major operators provide CRBT services, and constantly introduce new CRBT products and services to meet the different needs of users. Users can purchase and set up CRBT by SMS or downloading APP, and generally need to pay a certain fee. In a word, CRBT is a personalized ringtone, which allows people to express their personality and preferences through ringtones.
