Ohio is mostly covered even in the archaic map . I remember when I got Sprint, there was no native coverage to my east. My home site was the edge of Sprint's footprint in the mid 2000's. The roaming was probably alltel. Alltel built out here several years before the others. Some of the towers have been around so long that they're painted red and white (still). And yet a strobe was installed atop the local tower anyway once Verizon took over. I guess they want to make absolutely sure planes don't crash into it.
