Why do text messages from mobile phone numbers always prompt me to answer or not?

Text messages from mobile phone numbers always prompt you whether to accept or not, which may be due to the following reasons:

1. SMS receipt service: This is a SMS service launched by China Mobile. After sending a point-to-point short message, the user will receive a status receipt report to inform whether the short message has been sent successfully. This service aims to solve the problem of "uncontrollable" in the process of sending short messages and ensure that every short message can be received by the receiver.

2. SMS delivery notification: In order to ensure accurate and timely delivery of SMS, China Mobile will provide SMS delivery notification service to users. When the short message is successfully sent to the receiver, the user will receive a short message sending notice, informing that the short message has been successfully sent.

The above two points are to improve the sending rate and accuracy of short messages, so mobile users will prompt whether to accept them when they receive short messages. If you don't need this service, you can contact the local mobile customer service for cancellation.
