"While Verizon remains on top in most categories, results from our most recent visit to Tampa show that all four carriers are providing their customers a highly reliable mobile experience," said Bill Moore, RootMetrics CEO. "Verizon ranked first on our network reliability index, but with scores above 98 for all four carriers, reliability was strong across the board. While Verizon's median speeds are impressive, we also saw gains in the market from Sprint and T-Mobile. In the end, all four carriers are providing strong reliability and speed in the Tampa market."
