Why does someone send a message that my apple 13 doesn't ring?

1. Check whether the phone is in mute or vibration mode. 2. Adjust the ringtone size: slide down the screen top curtain-long press the sound icon to enter the sound interface-volume-ringtone, turn up the ringtone volume and try again. 3. If there is still no ringtone, please try to change the ringtone of the phone's built-in system. If the problem still exists, please take the purchase invoice, maintenance card and machine to the mobile phone service center, and the professional after-sales engineer will help you test it.
