Sorry to hear that @pmark019 ,
Let us further isolate the concern. Upon checking www.gsmarena.com the phone supports LTE for band 1800.
It should be supported for LTE. But there is still a disclaimer since I am not that fully sure.. Best way is to isolate this concern if you can borrow a micro simcard that can acquire LTE using other phones which are Globe provided. If it works with your phone maybe the LTE service is not yet activated on your account.
Hope this helps,
