My white iPhone 5 is here for AT&T. When the wifi is turned off, my data doesn't work. I can't surf, check email, weather, etc. I can still call people though. Data is enabled in settings. Any ideas?
Have you tried turning it off and turning it back on? The rep at the store I went to told me I would likely have a data issue until I did that, and he was right. It works fine now.
