I can't get a message when my Apple phone is playing. What happened?

Apple mobile phone can't receive text messages while playing. Maybe it's not that the mobile phone can't receive the text message, but that you set it so that it doesn't pop up. You can remind your SMS in the settings of your Apple phone, turn it on, and then turn on the display mode of your SMS reminder. When you play, his leaves will pop you up and receive some short messages, otherwise he (she) will receive your short messages, go in and go in the short message function, but it won't.
