Where are you located? From some other forums, LHN is only on DirectTVNow if you are in an area where that is the regional sports network (RSN). In central Iowa, the RSNs are listed as FSMidwest and NBCSports-Chicago.

Also they say you need to NOT try the basic package to have geographic-based RSNs.
However, would a DirectTVNow Trial username/login get access to LHN via the WatchESPN app?
