The mobile phone suddenly can't send and receive text messages. What happened?

2. The mobile phone storage is full;

3. SMS center number setting;

4. The positioning signal is poor;

5. Mobile phone settings.

Solution:

1. Mobile phone arrears: just pay the phone bill.

2. The phone is full: you need to delete some short messages or other things that occupy memory.

3. SMS center number setting: You can set the SMS center number correctly in the mobile phone information setting.

4. Poor signal in the wrong place: In tunnels, tunnels, deep mountains and sparsely populated places, the signal is generally poor, and the mobile phone cannot receive short messages. As long as you change your location and go to a place with good signal, you will naturally receive the message you didn't receive.

5. Mobile phone settings problem: Some system settings have been changed. Enter the mobile phone settings and click "Backup Reset". Click "Settings Reset", all mobile phone system settings will be restored to the factory settings, but no data will be lost.

6. Blacklist and information interception are set: therefore, blacklist interception needs to be removed.

7. Mobile phone hardware/system problems: Smartphones can only swipe their cards.
