Still, it's a start and Verizon had to hit 39 sometime before hitting 258. Besides, while trailing Verizon, AT&T still has the second highest total of LTE coverage amongst the four major U.S. carriers. Sprint is still working on launching LTE for its first market, most likely later this summer. Still, the carrier has already decided on where it will first offer the zippier service. Additionally, Sprint has already started selling handsets that support LTE. T-Mobile is well behind Sprint in terms of planning its 4G LTE pipeline. The nation's fourth largest carrier expects to start offering LTE service in 2013.
