The mobile phone is out of service. Can you get the message?

In this case, you can receive short messages.

SMS is sent through SMS center, and there is a special agreement between SMS center and mobile phone users. As long as the SMS center does not send a "stop communication" instruction to the mobile phone user, the mobile phone can receive SMS normally. The short message center will keep short messages for mobile phone users for a period of time, so that users can also receive these short messages after restarting.
