Don't be alarmed by Dish's lack of 4G coverage in Naperville. Dish has a newly-built network that's 5G-only.

US Cellular And Dish Roaming Coverage

US Cellular does not have native coverage in Naperville. However, some US Cellular subscribers may still have coverage in Naperville thanks to roaming agreements.

The 97% figure for Dish may understate what subscribers in Naperville experience after accounting for roaming agreements.
