Apple's mobile phone can't receive text messages.

The reasons for not receiving the SMS are as follows:

1.

There is no signal on the mobile phone, so I can't receive the text message. You can receive it when the signal is good.

2.

The mobile phone is in flight mode, so the communication service cannot be used. Just turn off the flight mode.

3.

If the mobile phone card is damaged and you can't receive the SMS, go to the local business hall to reissue the card.

4.

When using imessage, the device must be in a networked state, and the object receiving information can only achieve this operation if imessage is enabled and networked.
