If your cell phone provider is not Verizon and you live in North Dakota, you don't have the best coverage. This is not a sales pitch. It's a fact.

RootMetrics is an independent firm that tests the four major carriers in each state each year to see which companies provide the best coverage.

For the sixth year in a row, Verizon has ranked the best out of the four largest carriers in the United States.

If you live in North Dakota, this likely comes as no surprise.
