Why can't my mobile phone receive verification code messages sometimes?

If you can't receive some short messages by using vivo mobile phone, you can check them by the following methods:

1. Check whether the number blacklist is set in the harassment information interception.

Enter the information app-circle icon in the upper right corner-harassment information interception-blacklist management-number blacklist. If the number is blacklisted, incoming calls and messages will be blocked.

2. Check whether there is a third-party housekeeper software to intercept SMS.

Some security management software will intelligently filter the received short messages. It is recommended to do a good job of data backup and uninstall the application. These software lists are generally named as "XX housekeeper" or "XX security assistant".

Please check whether you just can't receive the short message sent by Apple.

If you just can't receive the SMS from Apple's mobile phone, you can receive the messages from other mobile phones. It may be because the mobile phone number was bound to the Apple device before, and the other party sent iMessage instead of ordinary SMS. 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. Check whether the short message contains sensitive words, which makes the mobile phone unable to receive it.

Ask the other party to use the test message, such as send: thank you, to see if it can be received normally. If it can be received normally, it means that the text message sent before may contain sensitive words.
