This movie scared the actual life out of me and the suspense was incredibly unreal. I was on the edge of my seat the whole time. The only thing that annoyed me was the fact that 911 can still be called even without a signal because 911 is a priority signal so if you dial 911 your phone will be able to send a signal through any tower that has some kind of connection. If I remember correctly 911 calls can also be connected through satellite? I genuinely hate how they saw no signal and didn't even attempt to call 911, even at their most desperate point.
