Excuse me, what is the fee for starting to use business color ring tones?

1. 5 yuan/monthly/door color ring back tone function fee will be charged for each mobile phone with color ring back tone function, and users with color ring back tone function need not charge again;

2. Commercial CRBT information fee: 15 yuan/month/paid number, including five fixed-line or mobile phone numbers, and then 15 yuan/month is added for each additional five numbers. If there are less than five doors, five doors are counted.
