How come the iphone 5 doesn't say i'm on LTE?

There no Internet so shouldn't i be running on LTE? My iphone says i'm on 3G right now but i thought iPhone 5's use LTE?

Sometimes LTE isn't available, since it's a somewhat new technology and not all the radio towers are up supporting it. Try moving around to a different place, hard resetting your phone, or turning LTE off then back on in settings
