I switched to Sprint last year when my Att bills were reaching 250 a month for two lines. One of the biggest mistakes I've ever made, absolute horrible service. Not worth the savings.
I was going to cancel the first month while I still had the option, they told me a tower was out and my first two months will be free. I thought wow, Sprints customer service rocks! They really sucked me in, a year + in and nothing has changed. Many calls to bitch and complain but it goes nowhere. I used to sync my phone with my car and listen to music that way, it's almost impossible with Sprint. Constant buffering, calls always drop. It's also not just where I live, whenever I travel too. I'm not joking when I say my service was better with another carrier ten years ago.
Sprint is the reason people go crazy, smoke signals are more reliable.
