This is what my AT&T app says about my LTE plan. Does the iPhone use LTE basic? It used to say 5 GB but now it gives me the 9999 GB. Does that seem right? I have the grandfathered unlimited plan. What's weird is that on the AT&T website, the system shows I have a dumb phone with unlimited data for dumb phones. When I called AT&T they show I have an iPhone 5 with iPhone 5 unlimited. I haven't had a dumb phone since before the first iPhone.
