Last year I was out driving after dark and I had a blowout on a country road. It was pitch dark, there were no houses around and I was stuck there on the side of the road. I whipped out my ATT cell phone. No service! I was really in a pickle. After 10 minutes of stifling worry, I did get one bar on my phone, and amazingly I was able to call home and get help. But it got me thinking that things could have gone so much worse. I made the switch to Straight Talk with Verizon towers. I haven't found a place that I can't use it yet. They have a reputation for coverage anywhere and after this experience, I just want to be as sure as I can be that I can use my phone in an emergency.
