So, I've been with AT&T for a few years, and have a iphone 7 plus. I'm not pleased with my phone AT ALL, and think it's absurd to pay what I am, for a phone that works half the time. So, I'm thinking about doing a prepaid flip phone or something similar form Walmart. I want it to make phone calls, that's it. Anybody have any luck with the prepaid phones? What do you use personally?
