My Lenovo S7 mobile phone can't receive short messages. What happened?

You need an information center code to send messages. You should not set the information center code. ..

In fact, the mobile phone has been set up when it leaves the factory. Maybe you deleted it.

You should go to the local area and ask what your information center code is, then enter the number on the mobile phone information center code and press OK, and you should be able to send and receive messages.
