Why can't Apple receive SMS?

The reasons why Apple's mobile phone can't receive SMS are as follows:

1, the phone is in arrears and stopped.

Of course, if the phone stops, the SMS will be invalid, as long as it is recharged in time.

2. The storage of the mobile phone is full.

If the storage space of iPhone is full, you will not receive SMS. It is recommended to delete unnecessary text messages or other contents that occupy memory before trying to receive text messages. This situation is generally more common in non-intelligent machines.

3. Mobile phone information filtering has been turned on.

When "Filter iMessage Information from Unknown Senders" is turned on, you will not receive SMS messages sent by strangers. You can turn off or on filtering unknown senders in iPhone Settings-Info.

4. Start the flight mode.

If the iPhone unexpectedly turns on airplane mode, you won't receive any text messages during this time. You can turn off the airplane mode option in the Settings interface.

5. Open the blocked contact.

If Blocked Contacts is turned on, you will not be able to receive SMS messages with blacklisted numbers. You can delete some numbers by going to Settings-Messages-Blocked Contacts on the iPhone.
