How is the on-hook SMS service charged?

On-hook SMS is a new form of direct media provided by China Telecom for postpaid landline customers and Tianyi mobile phone customers. When the system determines the call status of the called party, if it meets the called party's settings (such as: connected, busy, no answer), it will have a choice for the calling customer who belongs to the mobile terminal (including Tianyi, PHS and other network mobile phones) Send customized text messages to the called party secretly. The text message content can include phone number, company name, product brand, office address, promotional information, personality statement and other information. It can not only assist the called user in advertising the company's products, but also facilitate the calling user to save the merchant's consultation information.
