If you use a vivo mobile phone, you can investigate and handle it in the following ways:

Case 1: Some short messages cannot be received:

1. Enter the information APP-- "circle icon" in the upper right corner-harassment information interception-blacklist management-number blacklist. If the number is blacklisted, calls and information will be intercepted

2.

3. If you just can't receive the short message sent by Apple's mobile phone, you can receive the information sent by other mobile phones, probably because the mobile phone number was bound to an Apple device before, and the other party sent an iMessage instead of an ordinary short message. Please refer to Apple's official instructions to unbind the mobile phone number from the Apple device. The specific steps are subject to Apple's official instructions.

4. Please ask the other party to use test messages, such as sending: hello, thank you, etc., to check whether they can be received normally. If they can be received normally, it means that the messages sent before may contain sensitive words.

In case 2, all the short messages cannot be received:

1. Try to switch the airplane mode, or restart the mobile phone and try again after triggering the network.

2. The third-party SMS APP may have compatibility reasons, so it is recommended to use the SMS APP that comes with the system. Enter Settings-Applications and Permissions-Permissions Management-Permissions-Default Application Settings-Information, and set it as Information.

3. It is recommended to put the SIM card on other mobile phones to receive the SMS test. If you still can't receive SMS, it is recommended to consult the customer service of the operator.

4. Go to Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore.

Note: "Restore all settings" will not delete any data or media files, but only restore all settings of the mobile phone (such as set wallpaper, unlocking style, WiFi, default opening program, desktop layout, etc.), and some third-party application accounts need to log in again. Please make sure that it will not affect the use of the software before operating. For the sake of data security, it is recommended to back up the mobile phone data in advance before operation. (You can enter the cloud service-device cloud backup-backup data type-system data-return-immediately back up some backup system settings and desktop layout; Cloud service-data synchronization-turn on WLAN, Bluetooth, etc. to synchronize data to cloud service)

5. If the above methods cannot be solved, please back up the important data on the mobile phone in advance and take the mobile phone to the vivo customer service center for testing and processing.

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoice/warranty card/ID card) when going, and call the staff of the service center in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
