He's lying about Band 71/13. They are not harmonically related (i.e., one frequency a multiple of the other). Band 13 is in the 700 MHz range; Band 71 is in the 600 MHz range. Verizon is the largest carrier in the US and their LTE coverage network is based on Band 13, the only nationwide license in the US. Other bands are used to add capacity in urban areas. I'm in an urban area and the only Verizon LTE signal I get, just barely, is on Band 13. In some places, though, I still get their 800 MHz CDMA signal, which has amazing penetrating power. I use an aging Blackberry now and would have considered this phone if it were Verizon-compatible.
