I can't see the message in the inbox.

The text boxes are all arranged in chronological order. What should your situation be like? What is the date setting of the mobile phone? Earlier than? The date of receiving the message, so that the received message will not be displayed according to today's date, and you will not see it easily.

In short, the new message is usually the last one (easy to find and see), and now your message is the first one.

It can be solved by doing it in time setting.
