How can I be sure that the other party has received the text message?

1. Under normal circumstances, the short message should be sent immediately, and a prompt of "successful sending" will be displayed. If after sending the message, there is no prompt of successful sending, or a prompt of "failed sending" is displayed, it means that the other party has not received your message. Of course, in some cases, the unstable network service and other reasons will also lead to the failure of sending.

2. SMS has a delivery report. As long as it is turned on, when you send a message to the other party's mobile phone, you will see a successful report. If it doesn't arrive (stop, etc. ), there will be no delivery report, and after a certain period of time, delivery failure will be displayed.

3. If the other party replies to you, it also means that the other party has received the message.

4. Mobile users can open the "short message receipt" service. According to different regions, the monthly function fee is 2-3 yuan. When the other party receives a text message, it will receive a text message reminder.
