It's not a "not "real 4G"". It's simply not a 4G.
4G is not a real thing! I don't get why you people don't understand that hehe. There's no tangible thing as 4G. It's a standard that's defined by some body somewhere, and that body is the ITU and they redefined it. People who keep saying it's not "real" 4G are so silly beyond the point of belief hehe
