It seems that all the major carriers claim to have the best 4G coverage. But this can be deceiving because some of the carriers take license with their definitions of 4G coverage. 4G is NOT necessarily the same as 4G LTE. The difference can be huge. All of Verizon Wireless’s 4G service is 4G LTE. Verizon has updated its coverage map to show where 4G service is available for Verizon, AT&T, Sprint and T-Mobile.
