If the fastest mobile speed across the nation is your priority, looks like it’s Verizon for you. 

For me personally, I chose to compromise for imperceptibly lower speed in exchange for much lower cost, so I chose Tmobile. However if you must have the highest speed and you travel across the country a lot, Verizon might be worth looking into if you haven’t already.

For the second year in a row, Verizon Wireless takes the crown as America’s fastest mobile network by delivering the quickest speeds and the best coverage across the map.
