Why isn't my phone notifying me of text messages?

[AC Question]

When I receive a text message my phone doesn't light up. And when I do turn the phone on there is no indication anywhere that I have a text. I have to open my messages app every time I turn the phone on to make sure I am not missing my text messages. So frustrating!!! Please help!
