phone won't ring calls go straight to voice mail

Same here. I am having the similar issue regardless of which state I'm in. Mostly notice in my home area, but that's where I'm usually are.. I also called T and suggested to reboot my phone lol, asked them to check the towers, but I think that is more global problem 😥

I was also thinking to switch to 3G when I'm expecting a call, but that is just crazy.
