Greater Philadelphia here is five counties in Pennsylvania: Philadelphia County, which is the city itself, and Bucks, Chester, Delaware and Montgomery counties around it. The metro area also crosses into New Jersey, Delaware and Maryland; those counties are not in this guide.

No carrier is the clear outdoor leader in any of the 5 counties: in Bucks, Delaware, Montgomery and Philadelphia all three are within 5 points of each other, and in Chester no carrier clearly leads once the county's water is allowed for. In a moving car, AT&T leads in 4 of the 5 counties (Bucks, Chester, Delaware and Montgomery), with Verizon close behind in Delaware and Montgomery; in Philadelphia all three are within 5 points of each other. In Philadelphia itself, the only Greater Philadelphia city among the 300 largest in the US, no carrier is the clear leader outdoors or in a car.
