What does the telephone bill mean by charging for audio-visual materials?

This means that the video that needs to be charged is requested by phone, and the video provider deducts the phone bill through an agreement with the communication operator.

This is commonly referred to as the SP service of a third-party provider. Some music, videos, ringtones and information are charged in the process of surfing the Internet through WAP, but users and third-party providers cannot trade directly. The third-party provider deducts the phone bill through the agreement with the communication operator, and the communication operator is equivalent to collecting it.

Many times shanzhai mobile phones automatically send short messages to order these services, because communication operators are also responsible. Because communication operators have certain interests, they are unwilling to make efforts to ban illegal third-party service providers.
