It has a small trick at first you learn about the hello tune activation date.
Hi friends this is for only airtel users. Airtel introduced Song Catcher. Dail 393 record your favorite song for twenty seconds
Airtel reduce the monthly rental after the 30th day of activation so you must know the activation date...
after 28th or 29th just type YES and send to the song's code.
Change your song every month without any monthly rental problems
