Sometimes my phone does not ring on my end and the other goes straight to voice mail. Also sometimes if someone sends a text, I might not get it until hours or even the next morning. It's like I'm in a bad area but I know that's not the case because my daughter has the same phone and doesn't have this problem. I've tried updating the towers and it hasn't helped. This does not happen all the time but enough that I'm about ready to throw it out window.
