How do I know the other person is reading the text message we sent?

Start with the other party's mobile phone and cancel his SMS receipt service. Just send "QXHZ" to 10086. After he sends a message, he won't receive a system reminder. You must prevent the other party from opening it again and then opening it again. Anyway, this service is free. Put your mobile phone in a place where the signal is extremely weak and you can't get it. I sent it to a friend of mine, but he didn't turn off his phone, but the system prompted the other party that he hadn't received it yet, and it took a long time to receive it. God, the signal is terrible. Try it, it may not work. Besides, even if you receive a text message, how will the other party know that you have read it? The reminder service only reminds the other party whether it has been received, and then it will say that the mobile phone has been left at home or turned off.

The short message receipt service is a short message value-added service launched by China Mobile for individual users. After using the mobile phone to send SMS normally, the mobile phone will immediately display the words "Message sent". But this only shows that the short message has reached the short message center normally; Doesn't mean the other party received it.

After handling the business, the other party successfully receives the short message, and the sender will also receive the short message prompt.
