Local considerations & tips
Historic & Federal Buildings
Thick masonry in historic rowhomes and federal buildings weakens indoor signal; Verizon and AT&T low-band and Wi-Fi calling perform best.
The Metro
WMATA now has cellular service across the system; T-Mobile and Verizon are the most consistent in the deeper tunnels.
Event Congestion
Mall events, inaugurations, and big rallies congest networks downtown; priority-data plans hold speed in the crowds.
