AT&T's LTE Footprint Swells With New Markets
Still missing...
Glaring omissions on 4G LTE coverage are Philadelphia and Detroit. These are pretty much the only top 20 cities that are not covered yet....
They may not have adequate 700MHz spectrum holdings there to properly cover the area with quality LTE?
...
Detroit goes live in approx 2 months. You can catch glimpses of the LTE insignia on your device now and then.
