In 24 of the 25 largest US cities, no carrier clearly leads on outdoor coverage in filings to the FCC as of December 31, 2025: the three are within 5 points, or differ by no more than the share of the city that is water. In most big cities the FCC figures don't separate the carriers, so price and the signal inside your own building are better ways to choose.
