Does the telephone notification include text messages?

Hello, dear. Hello, the number you dialed is busy, and he will be notified by SMS if there is an incoming call. Goodbye, in this case, this person should have set Do Not Disturb, and he may be busy. When someone called, he set up a short message notification to avoid missing the message. It is also possible that he doesn't like being disturbed by other people's phone calls, so he set up a unified mobile phone so that anyone who calls can receive SMS notifications.
