That phone they are talking about is awesome. I know this because I have one. I got it right after Bob left, and I needed a way to keep in touch with the kids while I was working. I went into Walmart not knowing exactly which cell phone company I wanted to go with, and ended up with my phone simply because I could not afford the deposits on the "regular" cell phone plans.
You have no idea how happy I am with the way things worked out. My phone did not come with contract. I simply buy a phone card every month for $45 and add it to my phone. That $45 buys me unlimited talk, text, and web. I mean, these phones have everything you need to stay connected. I can check Facebook whenever I want, or I can simply call a friend. There are no overage charges, which drew me in hook, line and sinker. I mean, with three kids who love to text and talk on the phone, I know I would be paying much more with a "regular" cell phone plan.
I would recommend Straight Talk phones to everyone. I wouldn't trade mine for anything. Well, maybe for one that has a full keyboard so texting is a little easier.
