No SMS Notification

[Android Central Question]

I have problem with SMS on J3 2016. Gave it to my little sister and she clicked something and now I don't see SMS notification and don't even hear it. When I get message I don't get notification, vibration, beep or anything, just it shows that there are one unread message. I need it because of my job. No, she didn't turned off volume, I hear all other notification, she didn't changed notification melody. Don't know what to do.
