Caller tune is a value added service through which one can entertain their callers with their favourite music, quotes, jokes or anything instead of the regular tring-tring. One can choose from the hit Bollywood songs, devotional contents, international hits, instrumental tones, jokes, status, humour and much more. And if that’s not enough, one can set his/her name as their caller tune. Caller tune is also referred as Caller Ringback Tone (RBT), and every country has its standard ringback tone set accordingly. In India, it is called by many names as its difference is more of a branding where Airtel calls it Hello Tune, Idea calls it Dialer Tune, Vodafone calls it Caller Tune and Reliance calls it Jio Caller Tune. These are all the same services where one can listen to a song or something instead of a tring-tring.
