Very anxious! Is there any way to see other people's mobile phone messages?

After sending a text message, the mobile phone has an unopened envelope sign, and after reading the text message, it will become an unsealed envelope sign. Methods: 1. Press the hang-up button after receiving the new information. 2. Go into the inbox, find the new email, and don't open it. 3. Press the function key to find "Forward". In this way, you can see the content of the message, and the new message is still an unopened envelope sign, and the owner of the mobile phone doesn't know that you have read it. Hehe, adopt first and then try!
