What happened when Huawei B 199 sent a message but failed to receive it?

See if your mobile phone is in arrears. You can't send and receive text messages when you stop.

Or did you set a blacklist in the mobile phone manager's house, which caused the short message to be intercepted and could not be received? If so, please delete the number from the blacklist and try again.

Is there a third-party application that intercepts short messages? Some security management applications will intelligently filter the received short messages. It is recommended to uninstall this application.

If you can't receive the SMS sent by Apple's mobile phone, the messages sent by other mobile phones will be received normally. It may be because your mobile phone number was bound to an Apple device before, and I sent you an iMessage instead of an ordinary SMS in the opposite direction. You can refer to Apple's official instructions to unbind the phone number from the iPhone device.

In addition, there are two kinds of short messages that Apple can send, one is ordinary short messages for a fee; The other is Apple's unique iMessage message, which is free and sent through data traffic. It can only be used between Apple phones, and other phones cannot receive it.

If the above methods can't be solved, it is recommended to back up important information, restore factory settings or upgrade the mobile phone system and try again.
