I just received a short message, but it disappeared inexplicably before I finished reading it, and I didn't delete it. What happened?

I don't think what you said can happen. Because the message has been sent, I can't get it back. It's like overflowing water. If it is a WeChat chat, it can be withdrawn within two minutes, and there is no withdrawal function after the short message is sent.

So the text message sent to your mobile phone can't be gone for no reason. It could be you. I accidentally pressed the delete button and deleted this short message.

You should stop obsessing about this matter. If this information is particularly important. The person who sent you the message will contact you again when he sees that you have not replied. If touching is not important, then don't worry.
