Angry wife rant

My husband works construction so he isn't home during the week, only on the weekends. I told him from now on he needs to keep his phone on loud at night, in case I go into labor. (I'm 38w 4d)  
Well, tonight he stopped texting me around 7:15. I tried calling him a few times just to talk. And he isn't answering. I've sent multiple texts and now I'm pissed. 
What if I was in labor?? His phone is not on loud. He's even said before that if he missed me being in labor and got to town after the baby was born that it would be easier for him. 
WHAT?! Are you kidding me? 
I'm so pissed off right now.
