What is the reason why the mobile phone can't receive SMS?

The mobile phone can't receive SMS for the following reasons:

1, cell phone signal problem. If the mobile phone is in a place with weak signal, it may lead to the abnormal reception of short messages. You can try to move to a place with better signal, or restart your phone to reconnect the signal.

2. The storage space of the mobile phone is insufficient. Many short messages are saved in the mobile phone card by default, and the storage capacity of the mobile phone card is small, so it is easy to be full. You can try to delete some old SMS messages or clean up the SMS storage space.

3.SIM card problem. If the SIM card has expired or been deactivated, it will also lead to the inability to receive short messages. You can try to take out the SIM card and re-insert it into the phone to ensure that the SIM card is inserted correctly and the contact is good.

4, mobile phone arrears or downtime. Verify that the mobile phone is in a normal state to receive short messages, and can't receive short messages when it is down or in arrears.

5, mobile phone settings. Sometimes, the SMS settings of the mobile phone may make it impossible to receive SMS. You can enter the setting menu of your mobile phone and find the SMS setting option to ensure that the SMS center number is set correctly.

6. Software for intercepting short messages is installed. Some security management applications will intelligently filter the received short messages, so it is recommended to uninstall this application.

7. The mobile phone operating system version is too old. You can try to update the operating system version of the mobile phone to solve this problem.

8. The network signal where the mobile phone is located is poor. If the cell phone network signal is poor, it may also lead to the inability to receive short messages.
