The landline can't receive the message.

If "Do Not Disturb" mode is turned on, the landline will not ring, and you will not receive text messages or phone calls. If the landline suddenly fails to receive the SMS, you can check whether the Do Not Disturb mode is turned on.

Fixed telephones can receive short messages. At present, China Mobile has been able to send short messages to fixed telephones, while China Telecom has converted short messages into voice short messages. Users write a short message on their mobile phones, and then they can send it to a fixed phone. After the mobile phone shows that the transmission is successful, the fixed telephone will ring, and the receiver will hear when he picks up the microphone: you have a voice prompt for a new short message, and then he can hear the content of the short message written by the user.
