How does China Mobile send information to the landline so that the landline can receive the information?

Hello. I used a mobile landline with similar functions, such as the functions of the old man-machine, SMS, call, alarm clock and date. In addition to the appearance, there is no essential difference from the mobile phone, and a landline card similar to a mobile phone card should be installed inside. If you send him a text message, you can send it directly, as long as the other party is turned on and has enough memory.
