Welcome to Android Central! What's the exact model number? If the phone didn't come with 4G support, you can't add it.

As I mentioned back in May, what's the exact model number of your phone? Also, what carrier do you have? The phone has to support 4G in the first place, and it also has to support your carrier's 4G bands.
