I can't receive SMS on my mobile phone. When someone sends me a text message, I have to turn it off and then turn it on. Why?

Hello, there are two possibilities for you to receive the text message.

One is antenna damage.

One is system failure.

Try the soft cell of the mobile phone first.

If it still doesn't work, send it to someone else to help you brush the machine.

Only when all the above methods fail can we prove that there is something wrong with the antenna of the mobile phone.

The address book is because you set the default, for example, the default display is stored in the SIM, so it can't be seen in the mobile phone.

Open the contact settings that you can change.
