Why can’t Apple receive text messages?

The reasons for this include signal issues, airplane mode, storage space, contact blocking, device updates, SMS settings, power management, etc.

1. Signal problem: Check the signal strength of your mobile phone. If the signal is weak or there is no signal, it may affect the reception of text messages.

2. Airplane mode: Make sure your phone is not set to airplane mode, otherwise you will not be able to receive text messages.

3. Storage space: If the phone’s storage space is full, text messages may not be received normally. Try cleaning up some unnecessary files or deleting some apps to free up storage space.

4. Contact blocking: If you cannot receive text messages from a specific person, it may be because the contact has added the number to a blacklist or blocked list. Check your contact settings to make sure it's not blocked.

5. Device updates: Make sure that the mobile phone system and SMS application are the latest versions. Outdated software may cause problems with SMS reception.

6. SMS settings: Enter the phone settings and check whether the SMS settings are configured correctly. Make sure your SMS center number is set to the correct carrier number.

7. Power management: Some Apple phones may enable power management functions to limit background application activities. Try turning off power management to make sure the SMS app works properly.
