The short message receipt service was cancelled some time ago. Why did I receive a message receipt?

Because when the system cancels the enhanced SMS call receipt service, the data cannot be synchronized to the SMS center, so we treat it as feedback. SMS receipt refers to the business that customers receive the receipt message immediately after sending the message with China Telecom's mobile phone. Suitable for China Telecom Tianyi mobile phone users. The contents of the receipt include the status information and additional information of whether the receiver successfully received it. The length of additional information is limited to 44 characters (including punctuation marks), and the content involves cultural entertainment, life health, practical knowledge, hot events and other fields. Suitable for China Telecom Tianyi mobile phone users. Receive the message receipt sent by the system after sending the message normally, and inform whether the message was sent successfully or not. At the same time, attach information within 44 bytes to the receipt SMS, which involves information in the fields of culture and entertainment, life and health, practical knowledge, hot events and so on. Users can personalize the information content and receiving method of receipt SMS. Requirements for mobile terminals: In order to ensure the basic functions of services, mobile terminals must support short messages. For better user experience, it is recommended to support flash messaging and WAP. The monthly fee can be handled through SMS, Huan go website and handheld business hall.
