Why can't Apple 13 receive the message from 1000 1?

If you don't receive the SMS, the following conditions may exist:

1. Check whether the mailbox is full. If yes, please delete some information.

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is a hardware reason.

3. Check whether it is intercepted by mobile phone interception software.

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.
