Hi oldsoul1989,
I don't have information on when the LTE service may be up and running in your area quite yet. I can tell you that a lot of time and approval from the local and state goverment must happen before LTE can be turned on. You can visit your local AT&T Company store, they have tools that can pull up the towers and see if any of them are lighting up LTE and would have more information about a possible hard launch date.
You can find your closest AT&T store by clicking Here.
Hope this helps!
