I'm at the end of my 2-year contract with AT&T. I've had AT&T forever, starting when it was GTE then Cingular. I don't have any particular beef with the company, coverage and quality have been fine, but now is the time to switch if it makes sense. I'm currently paying about $150/month for two phones and 2GB of data. I can get two new iPhone 5Cs for dirt cheap from Best Buy ($99 for a 32G model), but I don't have to stick with AT&T. What is Oppo's experience with other carriers?
